NEW QUESTION # 22
Challenge 2 -Task 1
In deploying a new application, a cloud customer needs to reflect different security postures. If a security zone is enabled with the Maximum Security Zone recipe, the customer will be unable to create or update a resource in the security zone if the action violates the attached Maximum Security Zone policy.
As an application requirement, the customer requires a compute instance in the public subnet. You therefore, need to configure Custom Security Zones that allow the creation of compute instances in the public subnet.
Review the architecture diagram, which outlines the resoures you'll need to address the requirement:

- A. It ensures all non-volatile memory on the terminated instance is securely wiped before reuse.
- B. It eliminates the need for hypervisors, reducing the potential attack surface.
- C. It guarantees complete isolation between customer workloads on different instances.
- D. It automatically encrypts data at rest on the bare metal instance.
Answer: A

What then could be causing the issue?
- A. The instance is not part of any Dynamic Group or the matching rule is incorrect.
- B. The instance is using the wrong OCI CLI authentication method.
- C. The policy is written at the root compartment instead of the production compartment.
- D. The bucket name is already in use, causing a conflict.
Answer: A
