A media firm has deployed Amazon RDS across multiple regions. The Operations team has shared an encrypted snapshot of DB instances with multiple accounts. One of the accounts wants to restore DB instances from this snapshot and is seeking your guidance to restore DB instances immediately.
What is the correct option to restore a DB instance?

Answer options:

A.Directly restore a DB instance from the encrypted DB snapshot.
B.Make a copy of the encrypted DB snapshot & restore the DB instance from the copy.
C.Create an unencrypted snapshot from the encrypted DB snapshot & restore the DB instance from the copy.
D.Create an unencrypted snapshot from encrypted DB snapshot & directly restore a DB instance from the DB snapshot.

Correct Answer: B
To restore a DB instance from shared encrypted snapshots, first, you need to create a copy of the DB snapshot & then need to create a DB instance from the copy of the snapshot.
Option A is incorrect as DB instances cannot be directly restored from an encrypted DB snapshot. First, a copy needs to be created from an encrypted snapshot & then a DB instance can be restored from the copy.
Option C is incorrect as there is no need to create an unencrypted DB snapshot to restore a DB instance from an encrypted DB snapshot.
Option D is incorrect as there is no need to create an unencrypted DB snapshot to restore a DB instance from an encrypted DB snapshot.
