• Question 214:

  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. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.

  B. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.

  C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.

  D. 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.

  Correct Answer: A

  If your organization is small, or if you are still in the proof-of-concept stage of evaluating Oracle Cloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes it easy for you to quickly view and manage all your resources. You can still write policies 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 a separate 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, while maintaining stricter permissions on the resources in your tenancy (root) compartment. https://www.oracle.com/a/ocom/docs/best-practicesfor-iam-on-oci.pdf

• Question 215:

  Which statement Is true about Data Guard implementation in Oracle Cloud Infrastructure (OCI) bare metal and virtual machine database systems?

  A. Primary and standby databases must be in the same OCI region.

  B. Both database systems must be in the same compartment.

  C. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).

  D. Primary and standby database versions and editions need not be Identical.

  Correct Answer: B

• Question 216:

  Which two resources reside exclusively in a single Oracle Cloud Infrastructure Availability Domain? (Choose two.)

  A. Identity and Access Management Groups

  B. Object Storage

  C. Web Application Firewall policy

  D. Block volume

  E. Compute instance

  Correct Answer: DE

  Availability Domain-Specific Resources DB Systems ephemeral public IPs instances: They can be attached only to volumes in the same availability domain. subnets: When you create a subnet, you choose whether it is regional or specific to an availability domain. Oracle recommends using regional subnets. volumes: They can be attached only to an instance in the same availability domain.

• Question 217:

  Your company uses the Oracle Cloud Infrastructure (OCI) Object Storage service to share large data sets with its data science team. The data science team consists of 20 people who work from offices in Washington, D.C., and Tokyo. While working in these offices, employees are assigned an IP address from the public IP range 129.146.31.0/27 Which two steps should you take to ensure that the Object Storage bucket used in this scenario was only accessible from these office locations? (Choose two.)

  A. Write an IAM policy that includes the conditional statement where request.networkSource.name =CorpNet

  B. Set the bucket visibility to public and only share the URL with the data science team via email

  C. Create a pre-authenticated request for each data set and only share with the data science team via email

  D. Create a Network Source named CorpNetwork with a CIDR block of 129.146.31.0/27

  E. Create a Network Source named CorpNetwork with a CIDR block of 129.146.0.0/16

  F. Write an IAM policy that includes the conditional statement where request.region = 129.146.31.0/27

  Correct Answer: CE

• Question 218:

  You have an AI/ML application running on Oracle Cloud Infrastructure. You identified that the application

  needs GPU and at least 20Gbps Network throughput. The application is currently using a VM.Standard2.1

  compute without any block storage attached to it.

  Which two options allow you to get your required performance for your application? (Choose two.)

  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.

  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved, but no block volume attached.

  C. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.GPU3.4 shape using the boot volume preserved and use the NVMe devices to host your application.

  D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.HPC2.36 shape using the boot volume preserved and use the NVMe devices to host your application.

  E. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved and attach a new block volume to host your application.

  Correct Answer: DE

• Question 219:

  Which option is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?

  A. Clone an existing volume to a new, larger volume.

  B. Restore from a volume backup to a larger volume.

  C. Shrink an existing volume in place with offline resizing.

  D. Expand an existing volume in place with offline resizing.

  Correct Answer: C

• Question 220:

  You deployed a database on a Standard Compute instance in Oracle Cloud Infrastructure (OCI) due to

  cost concerns. The database requires additional storage with high I/O and you decided to use OCI Block

  Volume service for it.

  With this requirement in mind, which elastic performance option should you choose for the Block Volume?

  A. Balanced Performance

  B. Higher performance

  C. Extreme performance

  D. Lower cost

  Correct Answer: B
