NEW QUESTION 84
Your on-premises hosted application uses Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options.
Which database offering on OCI would you select?
- A. bare metal DB systems
- B. Autonomous Transactions Processing (ATP)
- C. VM DBsystems
- D. Autonomous Data Warehouse (ADW)
Answer: A
Explanation:
Explanation
- In, Oracle Autonomous Database, Customers are not given OS logons or SYSDBA privileges to prevent phishing attacking.
- If a bare metal DB system requiresmore compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system.
You cannot change the number of CPU cores for a virtual machine DB system in the same way as metal DB system. Instead, you must change the shape to one with a different number of OCPUs Changing the shape does not impact the amount of storage available to the DB system. However, the new shape can have different memory and network bandwidth characteristics, and you might need to reapply any customizations to these aspects after the change.
NEW QUESTION 85
Which two statements are true regarding cloning a block volume?
- A. You can skip block volume encryption when creating a clone
- B. You can clone block volumes across regions
- C. You can change the block volume performance when creating a clone
- D. You can change the block volume size when creating a clone
Answer: C,D
Explanation:
Explanation
Youcan create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process.
A cloned volume is a point-in-time direct disk-to-disk deep copyof the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume.
You can only create a clone for a volume within the same region, availability domain and tenant. You can create a clone for a volumebetween compartments as long as you have the required access permissions for the operation.
during create a clone you can do the following
If you want to clone the block volume to a larger size volume, check Custom Block Volume Size (GB) and then specifythe new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to a larger size volume, you need to extend the volume's partition. See Extending the Partition for a Block Volume for more information.
If you want to change the elastic performance setting when cloning the volume, check Custom Block Volume Performance and select the elastic performance setting you want the volume clone to use. See Block Volume Elastic Performance for more information. You can also change the elastic performance setting after you have cloned the volume, see Block Volume Elastic Performance. If you leave Custom Block Volume Performance unchecked, the cloned volume will use the same elastic performance setting as the source volume.
NEW QUESTION 86
Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy PeopleSoft.
If your existing resources are being maintained in the root compartment, what is the recommended approach for defining security for the upcoming POC?
- A. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.
- B. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.
- C. Create a new tenancy for the POC. Provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment.
- D. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.
Answer: D
Explanation:
Explanation
If your organization is small, or if you are still in the proof-of-concept stage of evaluating OracleCloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes iteasy for you to quickly view and manage all your resources. You can still writepolicies and create groups to restrict permissions on specific resources to only the users who need access.If you plan to maintain all your resources in the root compartment,we recommend setting up aseparate sandbox compartment to give users a dedicated space to try out features. In the sandbox compartment, you can grant users permissions to create and manage resources, whilemaintaining stricter permissions on the resourcesin your tenancy (root) compartment.

You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have loggedinto the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?
- A. There is no internet gateway (IGW) set up for mount target traffic
- B. There is no route in your virtual cloud network's (VCN) route table for mount target traffic
- C. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
- D. There are no security list rules for mount target traffic
Answer: D
Explanation:
Explanation
Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you can add more.
These security lists provide ingress andegress rules that specify the types of traffic allowed in and out of the instances. You can choose whether a given rule is stateful or stateless. Security list rules must be set up so that clients can connect to file system mount targets. For more information about how security lists work in Oracle Cloud Infrastructure, see Security Lists in the Networking documentation. For information about setting up specific security list rules required for mount target traffic, see Configuring VCN Security List Rules for File Storage. About Security explains how security lists interact with other types of security in your file system.
