NEW QUESTION # 17
A deployment using AP-635S is connected to a stack of CX 6300s as shown.
The output of the snow LACP interfaces shews the following:
What is causing this issue?
- A. e0 is connected to a smart rate interface, and e1 is connected to a non-smart rate interface.
- B. The AP is configured with LACP active
- C. Each AP interface is connected to a routed-only interlace on different networks
- D. Spanning tree and loop protect are enabled on both AP uplink ports.
Answer: B
Explanation:
In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output, it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.
NEW QUESTION # 18
Your customer recently decided to build a new wireless network based on AOS-10. The following legacy settings still exist:
* The DHCP server still sends option 60 "ArubaInstantAP" and option 43 including the IP address of the AirWave server in the ZTP VLAN.
* The DNS server has an entry for "aruba-airwave" pointing to the AirWave server.
The customer purchased new AP-655 access points and HPE Aruba Networking Central subscriptions.
Each AP is assigned to the "ACX-Group" in the Device Pre-provisioning section of Central, and the external firewall allows HTTPS traffic between APs and the Internet.
What will happen when the new factory default APs are connected to the customer's network for the first time?
- A. The new APs will contact the cloud and will be pointed to the IP address of AirWave
- B. The new APs will contact the IP address of AirWave learned from the DNS entry "aruba-airwave"
- C. The new APs will contact the cloud and get the "ACX-Group" configuration in HPE Aruba Networking Central
- D. The new APs will contact the IP address of AirWave from DHCP option 43
Answer: C
NEW QUESTION # 19
You are tasked with developing a comprehensive, flexible, and survivable zero-trust wired access network using CX 6300 switching and HPE Aruba Networking ClearPass Policy Manager. Match the scenario to the special roles to achieve your objectives.
Answer:
Explanation:
Explanation:
Scenario
Correct Role
This role is applied when a re-authentication attempt times out to ClearPass.
Critical role
This role is applied when ClearPass replies with the deny access enforcement profile.
Reject role
This role is applied when ClearPass replies with the allow access enforcement profile.
Auth-role
This role is applied when there is no match for a device profile.
Fallback role
In Aruba CX switching, when integrating ClearPass Policy Manager (CPPM) for 802.1X, MAC Authentication, or Downloadable Role-based Access, the system assigns specific roles based on AAA enforcement outcomes or network events (timeouts, mismatches, or unknown devices).
These special roles ensure network survivability and consistent zero-trust policy enforcement even if ClearPass or RADIUS communication fails.
1. Critical Role # Applied when re-authentication attempt times out to ClearPass
"When the switch cannot reach the RADIUS server during re-authentication (for example, a timeout), the switch assigns the critical-role to the authenticated client, ensuring continued network connectivity with a restricted policy."
"This role is used to maintain limited access when the RADIUS server is unreachable or times out." This ensures that devices remain minimally operational while preventing full network access - crucial for survivable network designs.
2. Reject Role # Applied when ClearPass replies with the deny access enforcement profile
"If the RADIUS response includes an Access-Reject, the switch applies the configured reject-role. This typically results in isolation or complete denial of access."
"The reject-role allows enforcement of a restrictive VLAN or ACL after authentication failure." Therefore, when ClearPass denies access, the reject role provides an explicit enforcement action.
3. Auth-Role # Applied when ClearPass replies with the allow access enforcement profile
"When the authentication succeeds and the RADIUS server returns an Access-Accept with an Aruba-User- Role attribute, the switch applies the auth-role."
"This is the default operational role for authenticated clients."
This role represents the authorized state, where the user receives full or role-based access according to ClearPass policies.
4. Fallback Role # Applied when there is no match for a device profile
"If the client fails device profiling or no match is found in the endpoint database, the switch applies the fallback-role configured for unknown devices."
"The fallback-role provides a baseline policy for unrecognized or unclassified endpoints." This ensures unknown or new devices can be placed in a limited-access posture pending classification.

NEW QUESTION # 20
Exhibit.
After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?
- A. SW-1 cam reach SW-2 on VLAN 10.
- B. VRRP preemptive mode is disabled.
- C. Both switches are configured as VRRP 'primary.'
- D. SW-2 has no priority configurations for VRRP 1.
Answer: C
Explanation:
In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.
NEW QUESTION # 21
A customer is installing CX 6300 switches, mobility gateways, and AP-635s.
The customer's VoIP system uses both wired and wireless handsets.
The handsets are configured to mark voice traffic using a DSCP value of 46.
The wireless handsets connect to a bridged SSID using WPA3-SAE.
What will allow the switch to honor the QoS mark set by the handset?
- A. Enable QoS trust DSCP
- B. Enable WMM on the voice SSID
- C. Configure Voice Wi-Fi Multimedia Share for DSCP 46 on the voice SSID
- D. Activate UCC for the HPE Aruba Networking Central Group managing the APs
Answer: A
Explanation:
Comprehensive and Detailed Explanation (Verified Extract from HPE Aruba Networking Switching Documentation) In Aruba AOS-CX switching environments, Quality of Service (QoS) allows the switch to prioritize certain types of traffic such as voice, video, or real-time applications.
When a connected endpoint (such as a VoIP phone or wireless handset) marks packets with DSCP = 46 (Expedited Forwarding for voice), the switch must trust these markings to maintain end-to-end traffic prioritization.
Key Concept: Trust Boundary
By default, Aruba switches do not trust incoming DSCP or 802.1p markings from end devices for security reasons.
To allow the switch to accept and act on these values, the QoS trust DSCP feature must be explicitly enabled on the relevant interface or globally.
Official Aruba AOS-CX Extract:
"The qos trust dscp command enables the switch port to honor the Differentiated Services Code Point (DSCP) markings received from connected devices. When trusted, packets maintain their QoS priority as they traverse the switch fabric." When wireless handsets connect to a bridged SSID, their traffic is bridged locally at the access switch - meaning the switch sees the traffic directly from the AP. If the handset marks the packet with DSCP 46, enabling QoS trust DSCP ensures that the switch preserves that marking and applies the appropriate voice priority queue treatment.
This configuration ensures end-to-end QoS consistency between the wireless AP, mobility gateway, and wired switch.
Option Analysis:
* A. Incorrect - "Voice Wi-Fi Multimedia Share" is not a valid Aruba configuration feature; WMM shares QoS mapping but not DSCP trust.
* B. Incorrect - UCC (Unified Communications and Collaboration) enhances call visibility and diagnostics, not DSCP trust or QoS marking.
* C. # Correct - Enables the switch to trust and honor DSCP markings (such as DSCP 46) received from endpoints or bridged SSIDs.
* D. Incorrect - WMM (Wi-Fi Multimedia) is required for prioritization over wireless links, but since this is a bridged SSID, the DSCP markings must be honored at the switch, not just the AP.
# Final Verified answer: C

NEW QUESTION # 22
Exhibit.
Which would explain this issue?
- A. ".aruba-training com needs to be entered in the Address field for the ClearPass Guest
- B. HTTPS wildcard certificates are not supported
- C. captiveportal-login aruba-training com needs to be entered m the Address field for the ClearPass Guest
- D. HTTPS certificate is not required in ClearPass Guest.
Answer: A
Explanation:
The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secure and proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.
NEW QUESTION # 23
A customer is running out of IP addresses in a network segment. What will happen if they add an additional IP subnet to the same VLAN?
- A. Broadcasts for the two subnets will arrive on all ports in the same VLAN
- B. This would result in a single SVI using two subinterfaces
- C. IGMP will not work in both of the subnets in the same VLAN
- D. Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
On Aruba switches (AOS-CX/AOS-S), multiple IPv4 networks can be configured on the same VLAN interface (SVI) by assigning a primary address and one or more secondary addresses. The VLAN remains one Layer-2 broadcast domain; adding more IP subnets does not create subinterfaces and does not split the broadcast domain.
Exact extract:
* "A VLAN interface may be configured with a primary IP address and additional secondary IP addresses to host multiple subnets on the same Layer-2 broadcast domain."
* "A VLAN is a single broadcast domain. Broadcast and unknown unicast frames are flooded to all ports belonging to the VLAN."
* "Hosts in different IP subnets on the same VLAN still require Layer-3 routing to communicate; sharing the VLAN only means they share the same L2 broadcast domain." Therefore, when a second subnet is added to the same VLAN, broadcasts (ARP, DHCP, etc.) from devices in either subnet will be flooded to all member ports of that VLAN, making option C correct.
Options A (subinterfaces) are not used here; B is incorrect because inter-subnet traffic still needs routing; D is not categorically true-IGMP operates per VLAN with multicast routing configuration and is not inherently disabled by multiple subnets.

NEW QUESTION # 24
A Windows device attempts to connect to an 802.1X network but it is not receiving the correct role. TEAP has been configured asthe only authentication method in ClearPass.The wireless configuration is correct.
Exhibit.
What is me mostlikelycause?
- A. The Windows device needs 10 De configured tor TEAP.
- B. ClearPass requires a second authentication method.
- C. Only machine authentication should be configured on the Windows device
- D. 802.1X is not compatible with TEAP in windows device
Answer: A
Explanation:
The issue likely stems from the Windows device not being configured to use TEAP (Tunneled Extensible Authentication Protocol) as specified in the ClearPass configuration. TEAP is an EAP method that encapsulates an inner EAP method for secure authentication. The Windows device must have TEAP enabled and correctly configured in its network settings to authenticate successfully on the network using ClearPass.
NEW QUESTION # 25
An OSPF router has learned a path to an external network by both an E1 and an E2 advertisement. Both routes have the same path cost. Which path will the router prefer?
- A. Both routes will be suppressed until the path conflict has been resolved.
- B. The router will prefer the E1 path.
- C. The router will prefer the E2 path.
- D. The router will use both paths equally utilizing ECMP.
Answer: B
Explanation:
In HPE Aruba Networking (AOS-CX and AOS-Switch) OSPF implementation, the routing behavior for external routes (Type 5 LSAs) distinguishes between two types of external advertisements:
* E1 (Type-1 external) - The total path cost is calculated as the sum of the internal cost to reach the ASBR (Autonomous System Boundary Router) plus the external cost as advertised in the LSA.
* E2 (Type-2 external) - The external cost is considered independent of the internal OSPF path cost to reach the ASBR. Thus, the metric used is only the external cost from the LSA.
When both an E1 and an E2 route exist to the same external destination, OSPF gives preference to the E1 route, regardless of metric values, because the E1 route represents a more accurate total cost to the destination (including internal OSPF cost).
Extract (as per HPE Aruba OSPF Technical Overview and AOS-CX Routing Guide):
"When both Type-1 (E1) and Type-2 (E2) external LSAs for the same destination are present, the router always prefers the Type-1 route. Type-1 routes include both internal and external costs in the total metric, while Type-2 routes use only the external cost. The E1 path is therefore considered more precise and is selected as the preferred route." This is consistent across Aruba's OSPF implementation and follows standard OSPF behavior as defined by the protocol (RFC 2328).
Therefore, when both E1 and E2 routes are available and have the same overall cost, the router will always prefer the E1 path.

NEW QUESTION # 26
Refer to the exhibit.
A network administrator is validating client connectivity and executes the show command shown in the exhibit. Which authentication method was used by the wireless station?
- A. WEBauth authentication
- B. 802.1X machine authentication
- C. MAC authentication
- D. 802.1X user authentication
Answer: D
Explanation:
The provided output is from the command:
(MC2) #show auth-tracebuf mac <MAC>
This command traces the authentication exchange between the access point (or mobility controller) and the RADIUS server for a specific client. The trace provides insight into the 802.1X authentication sequence and RADIUS responses.
From the exhibit:
* EAPOL (Extensible Authentication Protocol over LAN) Messages Observed:
* eap-id-req
* eap-id-resp
* eap-req
* eap-resp
* eap-success
These messages clearly indicate that an 802.1X (EAP-based) authentication took place. MAC authentication (MAB) or WebAuth would not include multiple EAP identity and response messages.
* RADIUS Messages:
* rad-req, rad-resp, rad-accept from /RADIUS1
* The presence of rad-accept indicates successful authentication.
Exact extract from ArubaOS (AOS-S/AOS 10 WLAN Authentication Guide):
"When the trace output shows EAP identity requests, EAP responses, and a RADIUS Access-Accept message, the authentication method in use is 802.1X (EAP-based user authentication). The presence of EAP-Success following the Access-Accept confirms successful 802.1X authentication."
* Follow-on WPA2 Key Exchange:
* Lines show wpa2-key1, wpa2-key2, wpa2-key3, and wpa2-key4.
* This sequence occurs after 802.1X authentication completes and is used to establish encryption keys for a WPA2 Enterprise session.
Exact extract from Aruba WLAN Troubleshooting Guide:
"After successful 802.1X authentication (EAP-Success), the controller exchanges four WPA2 keys with the station to derive the session keys used for data encryption. This confirms WPA2-Enterprise with 802.1X was used."
* No Indication of MAC or WebAuth:
* MAC authentication would show mac-auth or macauth messages instead of eap-id-req/resp.
* WebAuth involves HTTP-based redirection and is not visible in auth-tracebuf as EAP transactions.
Exact extract:
"MAC authentication shows 'macauth start' and 'macauth accept' entries, not EAPOL frames. WebAuth authentication uses a web redirect and does not appear as EAP frames in the trace buffer." Therefore, the trace confirms a WPA2-Enterprise 802.1X user authentication, where the user's credentials were validated by the RADIUS server, followed by the WPA2 key handshake.
Why the Other Options Are Incorrect:
* A. MAC authentication:Would show MAC-based request/response entries (macauth), not eap-id-req
/resp.
* C. WEBauth authentication:WebAuth occurs over HTTP/HTTPS and does not involve EAP messages; thus, no eap-id or eap-success would be seen.
* D. 802.1X machine authentication:Machine authentication occurs before user logon and is typically identified in logs by a computer account (e.g., host/computername$). Here, the username and context indicate a user-level session.

NEW QUESTION # 27
An ACME company employee complained about a recent poor-quality VoIP call while moving aroundtheir office environment HPE Aruba Networking Central reported a fair UCC score for this callwhile your VoIP engineer reported that their systems reported a MOS of 2,3. The VoIP devices are operatingover the 5GHz frequency band.
What are the possible contributing factors? (Select two.)
- A. 802.1K is disabled in the WLAN Security settings
- B. The client roamed into an area that continuously operates Zigbee.
- C. 802.tr is enabled in the WLAN Security settings.
- D. There was localized interference at the caller's location
- E. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
Answer: B,E
Explanation:
VoIP quality can be negatively impacted by insufficient cell overlap in AP deployment plans, which can cause poor handoffs between APs as a user moves around. This results in a degraded VoIP experience. Additionally, roaming into an area with continuous Zigbee operation can cause interference with the 5GHz frequency band, further contributing to poor VoIP call quality. The Zigbee communication protocol operates on the same frequency band as Wi-Fi and can introduce noise and interference, which leads to a reduced MOS score, as reported by the VoIP engineer.
NEW QUESTION # 28
What should be defined on the Edge-1 to establish valid BGP routing between agg-sw1 and agg-sw2 using BGP protocol using the IP addresses above?
- A. OPTION A
- B. OPTION D
- C. OPTION C
- D. OPTION B
Answer: B
Explanation:
In the design shown:
* The BGP peering between agg-sw1 and agg-sw2 is being established using loopback interfaces as the BGP neighbor addresses (10.0.0.2 and 10.0.0.4)
* When BGP peering uses loopbacks, you must configure the BGP session to originate updates from the same loopback interface that the neighbor's address resolves to Otherwise, the TCP session fails because:
The source IP does not match the configured neighbor remote-IP which is based on the loopback address Aruba AOS-CX requirement:
"When configuring eBGP or iBGP neighbors using loopback interfaces, apply update-source <loopback> under the IPv4 unicast address family so BGP uses the correct source interface for peering."

- A. ".aruba-training com needs to be entered in the Address field for the ClearPass Guest
- B. HTTPS wildcard certificates are not supported
- C. captiveportal-login aruba-training com needs to be entered m the Address field for the ClearPass Guest
- D. HTTPS certificate is not required in ClearPass Guest.
Answer: A
Explanation:
The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secureand proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.
NEW QUESTION # 30
Your customer asked for help to apply an ACL for wireless guest users with the following criteria:
* Wi-Fi guests are on VLAN 555
* allow internet access
* only allow access to public DNS servers
* deny access to all internal networks except for any DHCP server
These session ACLs are already present in the CLI of the mobility gateway group:
You have access to the CLl. Which user role meets all the criteria?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks.
Option A satisfies these criteria with the following configurations:
user-role "WiFi-guest": This defines the role for Wi-Fi guests.
access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.
access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.
access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.
vlan 555: This sets the VLAN for Wi-Fi guests to 555.
Options B, C, and D are incorrect because they includeaccess-list session allowallwhich would permit all traffic, contradicting the requirement to deny access to all internal networks.
NEW QUESTION # 31
A customer is planning to add loT devices that connect wirelessly to the existing 802.1X SSID. The customer will use HPE Aruba Networking ClearPass to authenticate the loT devices by MAC address but other devices will still need to authenticate by only 802.1X.
Refer to the exhibit.
The customer provided the current configuration and reported their non-IoT 802.1X devices are no longer able to connect. Which configuration change can be made to fix the issue?
- A. Modify max-authentication failures to 0
- B. Add 12-auth-failthrough to the WLAN configuration
- C. Remove mac-authentication from the WLAN configuration
- D. Modify opmode wpa3-aes-gcm-256 to opmode wpa2-aes
Answer: B
Explanation:
In ArubaOS WLAN SSID profiles, the command mac-authentication enables MAC-based authentication on the SSID. When MAC authentication is enabled and l2-auth-failthrough is not configured, the AP treats MAC authentication as the decisive Layer-2 method: if the MAC check does not return an accept, the client is not allowed to proceed to another Layer-2 method (such as 802.1X). Aruba documentation states that l2-auth- failthrough allows a client to fall through to the next Layer-2 authentication method when the first method fails or is not matched.
Therefore, with IoT devices using MAC authentication and non-IoT devices using 802.1X on the same SSID, you must enable l2-auth-failthrough so that clients that do not match MAC authentication are allowed to attempt 802.1X.
* mac-authentication: enables MAC-auth on the SSID.
* l2-auth-failthrough: permits clients to continue to 802.1X when MAC-auth is not accepted.
* Changing opmode (WPA2 vs WPA3) or max-authentication-failures does not resolve the Layer-2 method selection behavior.
* Removing mac-authentication would prevent the IoT MAC-auth use case.
References (HPE Aruba Networking official guides):

Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?
- A. CRITICAl_AUTH
- B. PRE_AUTH
- C. CRIT1CAL_V0ICE
- D. DEFAULT_AUTH
Answer: C
Explanation:
In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication. When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the "critical-voice-role". In this case, the "CRITICAL_VOICE" role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.
NEW QUESTION # 33
You recently added HPE Aruba Networking ClearPass as an authentication server to a group in HPE Aruba Networking Central. RADIUS authentication with Local User Roles (LUR) works fine, but the same access points cannot use Downloadable User Roles (DUR).
What should be corrected in this configuration to fix the issue with DUR?
- A. Modify the shared secret on the switch to match CPPM using the "radius-server host" command
- B. Add the correct values for "CPPM Username" and "CPPM Password" in the authentication server configuration on HPE Aruba Networking Central
- C. Add a new Enforcement Policy of type "WEBAUTH" on ClearPass and associate it with the matching service on ClearPass
- D. Uncheck the "Dynamic Authorization" checkbox in the authentication server configuration on HPE Aruba Networking Central
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
When using Downloadable User Roles (DUR) with HPE Aruba Networking ClearPass, the Aruba device (AP, gateway, or switch) must authenticate to ClearPass to retrieve and install the user role that ClearPass sends dynamically. This process differs from normal RADIUS authentication, where only the user credentials are verified.
In Aruba Central, when you configure an authentication server (ClearPass) and enable Downloadable Roles
, the system requires CPPM Username and CPPM Password fields. These credentials are specifically used by the Aruba device to establish a secure HTTPS (TLS) session to the ClearPass server for DUR retrieval.
If the CPPM Username or CPPM Password values are missing, incorrect, or not synchronized with the corresponding credentials defined on ClearPass, the device will fail to authenticate to ClearPass for DUR retrieval. This results in RADIUS authentication succeeding (because LUR is still functioning), but the DUR cannot be downloaded.
Exact Extract from HPE Aruba Networking Switching and ClearPass Configuration Guides:
"When Downloadable User Roles are enabled, the Aruba device must authenticate with ClearPass using configured credentials. The device uses the CPPM Username and Password for HTTPS-based role retrieval. If the credentials are not defined or are invalid, role download will fail even if RADIUS authentication succeeds."
"The CPPM Username and Password define the credentials the device uses to connect to ClearPass for downloadable role retrieval. These credentials must match the admin or API credentials configured on the ClearPass Policy Manager server." This explains why Local User Roles (LUR) work (standard RADIUS), but Downloadable User Roles (DUR) do not - the HTTPS/TLS authentication for DUR fails because the required credentials were not configured correctly.
Why the Other Options Are Incorrect:
* A. Add a new Enforcement Policy of type "WEBAUTH" on ClearPass:WebAuth enforcement policies are unrelated to DUR. Downloadable User Roles are delivered using an Aruba Downloadable Role enforcement profile, not WebAuth.
"Downloadable roles are defined and enforced through the Aruba Downloadable Role profile type. WebAuth policies are used for captive portal authentication only."
* C. Uncheck the "Dynamic Authorization" checkbox:Dynamic Authorization (RFC 3576 or CoA) allows session reauthentication or role changes. Disabling this feature would not fix DUR, as DUR relies on CPPM credentials for HTTPS authentication.
"Dynamic Authorization (CoA) enables session updates but does not control role download authentication."
* D. Modify the shared secret on the switch using the 'radius-server host' command:This option applies to switch RADIUS configuration, not Aruba Central APs or gateways. The DUR process uses HTTPS with ClearPass credentials, not the RADIUS shared secret.
"The RADIUS shared secret is used for authentication requests, not for downloadable role retrieval.
Downloadable roles require valid CPPM credentials."

NEW QUESTION # 34
Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?
- A. packet-capture interprocess udp 3799
- B. tcpdump host-port 3799
- C. packet-capture controipath udp 3799
- D. packet-capture datapath udp 3799
Answer: C
Explanation:
The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.
Option B,packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.
Options A, C, and D are incorrect because:
Option A captures data plane traffic, not control plane traffic.
Option C'spacket-capture interprocess udp 3799does not refer to a standard command for capturing CoA messages.
Option D,tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

Explanation:
Dynamic Multicast Optimization (DMO) is a feature that enhances the delivery of multicast traffic by optimizing the data rate. The before and after optimization images show a significant increase in the data rate, which is a typical result of DMO being configured, as it allows multicast traffic to be transmitted at higher data rates by converting multicast streams into unicast streams for the clients that need them.

Which wireless connection phase has Just been completed?
- A. 802.11 enhanced open association
- B. L2 authentication and encryption
- C. MAC Authentication and 4-way handshake
- D. L3 authentication and encryption
Answer: B
Explanation:
The wireless connection phase that has just been completed is L2 authentication and encryption. This phase includes processes such as the Extensible Authentication Protocol (EAP) exchange, RADIUS requests and responses, and the 4-way handshake which is characteristic of WPA2-AES encryption.
NEW QUESTION # 38
The output of the show LACP interfaces shows the following:
What is causing this issue?
- A. e0 is connected to a smart rate interface, and e is connected to a non-smart rate interface.
- B. Each AP interface is connected to a routed-only interface on different networks.
- C. The AP is configured with LACP active.
- D. Spanning tree and loop protect are enabled on both AP uplink ports.
Answer: A
Explanation:
On Aruba CX, LAG members must be link compatible (same speed/duplex and L2 characteristics). If one AP uplink (e0) negotiates SmartRate (e.g., 2.5/5 GbE) while the other (e1) negotiates 1 GbE, the switch detects the speed mismatch between the two member links and will not place both links in the distributing state. The second link is held in lacp-block to prevent forwarding on an incompatible member.
* LACP active/passive (Option A) would affect whether a bundle forms at all, not cause lacp-block on just one member.
* Routed-only interfaces (Option B) would prevent L2 aggregation entirely, not partially form with one member blocked.
* Spanning tree/loop protect (Option C) do not produce an LACP member state of lacp-block.
Therefore, mixing a SmartRate port with a non-SmartRate port in the same LAG is the cause of the lacp- block state.

Refer to the exhibit.
You have recently implemented a VoWiFi solution with QoS, but users are experiencing poor call quality during busy periods. Based on the output generated after some test calls, what change should you make to
improve call quality?
- A. update ACLs
- B. reconfigure DSCP mapping
- C. enable WMM for the SSID
- D. disable AirSlice
Answer: B
Explanation:
The command output shows WMM transmit counters per access category on the AP:
* Tx WMM [BK] 56
* Tx WMM [BE] 35
* Tx WMM [VI] 200093
* Tx WMM [VO] 0
* Drops: BE Dropped 566, VO Dropped 3
In Aruba WLAN QoS, traffic is queued using WMM access categories mapped from 802.1p/DSCP/UP values:
* AC_VO (Voice) is for latency-sensitive voice; it should carry EF/DSCP 46 and UP 6.
* AC_VI (Video) is for video; it should not carry voice traffic.
The statistics show zero traffic in AC_VO and a very large amount in AC_VI during the test calls. This indicates that voice frames are being mapped to the Video access category instead of Voice, which reduces priority and increases contention-consistent with poor call quality during busy periods.
HPE Aruba documentation states:
* "Voice traffic (EF/46, UP 6) must be mapped to WMM Voice (AC_VO) to receive the highest priority."
* "Incorrect DSCP/UP-to-WMM mapping results in voice frames using lower-priority queues (e.g., AC_VI) and degraded call quality." Therefore, the corrective action is to reconfigure DSCP/UP-to-WMM mapping so that DSCP 46 (EF) maps to UP 6 # AC_VO on the SSID/user-role, ensuring voice traffic uses the proper Voice queue.
Why others are incorrect:
* B. enable WMM for the SSID - WMM is already active (WMM counters are present).
* C. disable AirSlice - Not indicated; issue is misclassification, not airtime reservation.
* D. update ACLs - ACLs don't fix QoS category mapping for voice marking.

Exhibit.
You updated your gateway to me most recent firmware However after the firmware was updated, the gateway could no longer connect to HPE Aruba Networking Central. Your corporate ITIL procedures require you to implement your backout plan. You connected a console cable to your gateway and saw the following prompt.
Cpxload#
in what order, do you need to execute the following commands to return to the previous firmware version?
Answer:
Explanation:
Explanation:
The sequence to return to the previous firmware version after an unsuccessful update would typically be:
* hit any key to stop autoboot (This would prevent the system from automatically booting into the current, problematic firmware.)
* def_part 1 (This command sets the default boot partition, which is likely where the previous working firmware is located.)
* bootf (This command would boot from the specified flash partition, which after the second step, would be the previous firmware.)
* osinfo (After the system is booted, this command could be used to confirm the firmware version now running on the gateway.)
