Question 5

Given this compartment structure:

You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment.
What will be the result of your attempt to move the compute instance to the new compartment? (Choose the best answer.)

A. After moving the compute instance, you must move the compute instance VNIC as a separate action.

The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment. C. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved. D. The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.
