A database administrator needs to move an Oracle database deployed on EC2 from one region to another. What steps must the administrator perform to accomplish this?

Answer options:

A.It is not possible to move an EC2 instance from one region to another.
B.Create a read-replica of the RDS database in another region. Promote the replica to a primary database.
C.Shut down the EC2, then take the AMI and copy it in another region. Launch a new EC2 instance from the AMI.
D.Configure a Multi-AZ for the database. Promote a Multi-AZ node to a primary database.

Answer: C
Option A is incorrect because it is possible to move EC2 instances from one region to another using AMI copy.
Option B is incorrect because read-replicas are the capability of Amazon RDS, not databases deployed to EC2.
Option C is CORRECT because to copy an EC2 instance from one region to another, you must first create an image from an existing EC2 instance, perform a copy of the image to a different region, and then create a new EC2 instance from that image. To maintain system integrity, it is recommended to shut down the EC2 instance before creating an AMI.
