NEW QUESTION # 17
What is recommended for uploading the XtremApp to the XMS?

• A. PuTTy
• B. WinSCP
• C. Win32Disklmager
• D. Technician Advisor

Answer: B

Explanation:
For uploading the XtremApp to the XtremIO Management Server (XMS), the recommended tool is WinSCP. WinSCP is a popular SFTP client and FTP client for Microsoft Windows that allows for secure file transfer between a local and a remote computer1. It is particularly useful for uploading files like XtremApp due to its graphical user interface, which simplifies the process of transferring files.
The steps for uploading the XtremApp to the XMS using WinSCP are as follows:
Download and install WinSCP on your local machine.
Open WinSCP and enter the XMS's hostname or IP address, as well as the username and password.
Navigate to the XtremApp file on your local machine within the WinSCP interface.
Drag and drop the XtremApp file to the desired directory on the XMS.
Verify that the upload was successful by checking the file size and timestamp on the XMS.
This method is recommended in the Official Dell XtremIO Maintenance Achievement document as it provides a secure and reliable way to manage files on the XMS1.

NEW QUESTION # 21
What is the maximum mixed read/write IOPS rate achievable in a two X-Brick XtremIO X2 array?

• A. 500 K
• B. 1000 K
• C. 300 K
• D. 600 K

Answer: D

Explanation:
This performance metric is derived from the system's ability to deliver linear scalability, meaning that two X-Bricks can deliver twice the IOPS of a single X-Brick configuration2.
The calculation for this is based on the performance of a single X-Brick, which can achieve up to 300,000 IOPS under the same workload conditions. Therefore, with two X-Bricks, the system can achieve double that amount, resulting in 600,000 IOPS1.
This information is crucial for planning and sizing purposes, ensuring that the storage array meets the performance requirements of the applications it supports2.

NEW QUESTION # 22
How much virtual hard drive space is recommended when deploying a virtual XMS?

• A. 80 GB
• B. 400 GB
• C. 900 GB
• D. 200 GB

Answer: D

Explanation:
When deploying a virtual XtremIO Management Server (XMS), it is recommended to allocate a virtual hard drive space of 200 GB. This recommendation is based on the requirements for the operating system, the XMS application, and additional space for updates, logs, and other system files that may be generated during operation1.
The deployment process would typically involve:
Preparing a virtual environment that meets the minimum hardware specifications.
Allocating the recommended virtual hard drive space of 200 GB to ensure adequate room for the XMS application and associated data.
Proceeding with the installation of the XMS application on the prepared virtual machine.
It is important to follow the official Dell XtremIO documentation to ensure that the virtual environment is correctly configured to support the XMS application2.

NEW QUESTION # 23
How much rack space is required for a four X-Brick XtremIO X2 cluster with a physical XMS?

• A. 19U
• B. 16U
• C. 21U
• D. 24U

Answer: C

Explanation:
XtremIO X2 clusters are designed for efficient space utilization in data center racks.
A four X-Brick XtremIO X2 cluster requires specific rack space allocation.
Each X-Brick occupies 5U of rack space. Therefore, four X-Bricks would require 20U.
Additionally, the physical XtremIO Management Server (XMS) occupies 1U of rack space.
In total, the four X-Brick XtremIO X2 cluster with a physical XMS requires 21U of rack space.

NEW QUESTION # 24
Which port is used to connect to the Storage Controller (SC) to service an XtremIO X2 with the Technician Advisor tool?

• A. Dedicated serial port on the back on the SC
• B. Dedicated USB port on the front of the SC
• C. Dedicated Management port on the back of the SC
• D. Dedicated USB port on the back of the SC

Answer: C

Explanation:
To service an XtremIO X2 with the Technician Advisor tool, the connection is made through the dedicated Management port located on the back of the Storage Controller (SC). This port is specifically designed for management tasks and allows service technicians to access the system for diagnostics and configuration using the Technician Advisor tool1.
The process typically involves:
Locating the dedicated Management port on the back of the SC.
Connecting a compatible cable from the technician's device to the Management port.
Using the Technician Advisor tool to perform the necessary service tasks.
This information is outlined in the Official Dell XtremIO Maintenance Achievement document, which provides detailed instructions for servicing and maintaining XtremIO X2 storage systems1.

NEW QUESTION # 25
How many expansions are required to expand a Starter X-Brick cluster to an eight X-Brick cluster?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
To expand a Starter X-Brick cluster (which typically begins with one X-Brick) to an eight X-Brick cluster, a total of three expansions are required. Each expansion step in XtremIO can typically double the number of X-Bricks, thus:
First expansion: From 1 X-Brick to 2 X-Bricks.
Second expansion: From 2 X-Bricks to 4 X-Bricks.
Third expansion: From 4 X-Bricks to 8 X-Bricks.
This sequence ensures that the storage array scales properly, maintaining performance and redundancy.

NEW QUESTION # 26
Which type of InfiniBand switch is used in a multi-brick XtremIO X2-R array?

• A. 24 port switch
• B. 36 port switch
• C. 12 port switch
• D. 18 port switch

Answer: B

Explanation:
In a multi-brick XtremIO X2-R array, a 36 port InfiniBand switch is used. This type of switch provides the necessary number of ports to accommodate the connectivity requirements of a multi-brick configuration, ensuring high-speed data transfer and communication between the bricks and other components of the storage array1.
The InfiniBand switch plays a crucial role in the XtremIO X2-R's architecture, as it allows for the interconnection of multiple bricks, which collectively contribute to the array's performance and scalability. The 36 port switch ensures that there are enough ports available for current use and potential future expansion1.

NEW QUESTION # 27

• A. Accommodate the routing for InfiniBand cables
• B. Manage the air flow between Storage Controllers
• C. Provide space for an additional XMS
• D. Accommodate the cable management duct

Answer: D

Explanation:
An extra rack unit space is used between X-Bricks when installing a multi X-Brick XtremIO X2 to accommodate the cable management duct. This space is essential for organizing and managing the cables, ensuring proper airflow, and making maintenance tasks easier.

NEW QUESTION # 28

• C. b and d
• D. a and d

Answer: C

Explanation:
Based on the provided exhibit, ports "b" and "d" are used for FC2 (Fibre Channel 2) and iSCSI1 connections on an XtremIO X1. These ports are designated for specific connection types to ensure optimal performance and correct configuration of the storage network.

NEW QUESTION # 29
After changing the IP addresses of the Storage Controllers, which XMCLI command is used to verify that those addresses are correct?

• A. pm-query-storage-controller
• B. show-xms-info
• C. show-storage-controllers
• D. show-clusters-info

The show-storage-controllers command is used in XMCLI to verify the IP addresses of the Storage Controllers after they have been changed. This command provides detailed information about the status and configuration of the storage controllers, including their IP addresses.

NEW QUESTION # 30
What is the correct sequence of steps to perform a planned shutdown of an XtremIO X2?

Answer:

Explanation:

1 - Verify no host I/O
2 - Verify the cluster PSNT and health

4 - Stop the cluster service
5 - Power off the hardware

NEW QUESTION # 31
In a multi X-brick cluster, what happens when both DAE Controllers in a single X-Brick fail?

• A. Only LUNs with data on that DAE go offline
• B. Entire cluster shuts down
• C. Cluster performance is degraded
• D. Cluster operations continue normally

Answer: A

Explanation:
In a multi X-brick cluster, each X-brick consists of multiple Disk Array Enclosures (DAEs) that work together to provide storage and data redundancy.
If both DAE controllers in a single X-Brick fail, the impact is localized to the LUNs (Logical Unit Numbers) that store data on that particular DAE.
The entire cluster does not shut down; rather, only the data on the affected DAE becomes unavailable.
This design ensures that the rest of the cluster continues to operate normally, albeit with potential performance degradation depending on the data distribution and workload.
