You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that the application be deployed in us-phoenix-1. Nor-mal usage requires 2 OCPUs.
You expect to have few spikes during the week, that will require up to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs. What is the most cost-effective approach to implement a highly available and scalable solution? (Choose the best answer.)

• A. Create an instance pool with a VM.Standard2.1 shape instance configuration. Set up the autoscaling configuration to use 2 availability domains and have a minimum of 2 in-stances and a maximum of 8 instances.
• B. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.
• C. Create an instance with 1 OCPU shape. Use a CLI script to clone it when more re-sources are needed.
• D. Create an instance pool with a VM.Standard2.2 shape instance configuration. Set up the autoscaling configuration to use 2 availability domains and have a minimum of 2 in-stances, to handle the weekly spikes, and a maximum of 4 instances.

You have the following compartment structure within yourcompany Oracle Cloud Infrastructure (OCI) tenancy:

You want to create a policy in the root compartment to allow SystemAdmins to manage VCNs only in CompartmentC. Which policy is correct? (Choose the best answer.)

• A. Allow group SystemAdmins to manage virtual-network-family in compartment Root
• B. Allow group SystemAdmins to manage virtual-network-family in compartment CompartmentB:CompartmentC
• C. Allow group SystemAdmins to manage virtual-network-family in compartment CompartmentC
• D. Allow group SystemAdmins to manage virtual-network-family in compartment Com-partmentA:CompartmentB:CompartmentC

Which technique does NOT help you get the optimal performance out of the Oracle Cloud Infrastructure (OCI) File Storage service? (Choose the best answer.)

• A. Serialize operations to the file system to access consecutive blocks as much as possible.
• B. Increase concurrency by using multiple threads, multiple clients, and multiple mount targets.
• C. Limit access to the same Availability Domain (AD) as the File Storage service where possible.
• D. Right size compute instances from where file system is accessed based on their network capacity.

(CHK) Your company recently adopted a hybrid cloud architecture which requires them to migrate some of their on-premises web applications to Oracle Cloud Infrastructure (OCI). You created a Terraform template which automatically provisions OCI resources such as compute instances, load balancer, and a database instance. After running the stack using the terraform apply command, it successfully launched the compute instances and the load balancer, but it failed to create a new database instance with the following error: Service error: NotAuthorizedOrNotFound. shape VM.Standard2.4 not found. http status code: 404 You dis-covered that the resource quotas assigned to your compartment prevent you from using VM.Standard2.4 instance shapes available in your tenancy. You edit the Terraform script and replace the shape with VM.Standard2.2 Which option would you recommend to re-run the terraform command to have required OCI resources provisioned with the least effort? (Choose the best answer.)

• A. terraform plan target=oci_database_db_system.db_system
• B. terraform refresh target=oci_database_db_system.db_system
• C. terraform apply auto-approve
• D. terraform apply target=oci_database_db_system.db_system

As a solutions architect of the Oracle Cloud Infrastructure (OCI) tenancy, you have been asked to provide members of the CloudOps group the ability to view and retrieve monitoring metrics, but only for all monitoring-enabled compute instances. Which policy statement would you define to grant this access?

• A. Allow group CloudOps to read compute-metrics in tenancy
• B. Restricting monitoring access only to compute instances metrics is not possible.
• C. Allow group CloudOps to read metrics in tenancy where tar-get.metrics.namespace='oci_computeagent'
• D. Allow group CloudOps to read metrics in tenancy where tar-get.metrics.monitoring='oci_computeagent'
