You are asked to implement the disaster recovery (DR) and business continuity requirements for Oracle Cloud Infrastructure (OCI) Block Volumes. Two OCI regions being used: a primary/source region and a DR/ destination region. The requirements are:
There should be a copy of data in the destination region to use if a region-wide disaster occurs in the source region Minimize costs Which design will help you meet these requirements? (Choose the best answer.)

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 discovered 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.)

You have set an alarm to be generated when the CPU usage of a specified instance is greater than 10%. In the alarm behavior view below you notice that the critical condition happened around 23:30. You were expecting a notification after 1 minute, however, the alarm firing state did not begin until 23:33.

What should you change to fix it? (Choose the best answer.)

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network Security Group with a Source Type: Network Security Group (NSG), Source NSG: NSG-050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:
However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host.
What is the root cause of this issue? (Choose the best answer.)

You have a 750 MIB file in an Oracle Cloud Infrastructure (OCI) Object Storage bucket. You want to download the file in multiple parts to speed up the download using the OCI CLI. You also want to configure each part size to be 128 MIB.
Which is the correct OCI CLI command for this operation? (Choose the best answer.)
