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 private subnet. The Compute instances have an attached Network Security Group with a Source Type: Network security Group (NSG) , Source 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.

You have been contracted by a local e-commerce company to assist with enhancing their online shopping application. The application is currently deployed In a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet and a database in a separate, private subnet.
The company would like to deploy another set of similar Infrastructure In a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically.
After deploying the additional infrastructure within the second region, how should you configure automated failover requirements?
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?
