An IT company is planning to deploy a single master Aurora MySQL DB cluster in the us-east-2 region. Operations Head explores options for a quick restoration that can be used with minimal service impact to the application.
Which option should a Sysops Administrator propose to complete restoration quickly?

Answer options:

A.Restore a DB cluster to a specific time using AWS Backup.
B.Restore a DB cluster to a point in time using DB cluster snapshot.
C.Restore a DB cluster to a specific time using Backtrack.
D.Restore to a DB cluster to a point in time using backup data.

Correct Answer: C
For a single master Aurora MySQL DB cluster, backtracking can be enabled during DB cluster creation. This enables DB clusters to rewind to a specific time. This is a quick option of restoring a DB cluster to a particular time as compared to restoration using DB cluster snapshots or from backup data.
Option A is incorrect as using AWS Backup to manage backup & restore is a manual DB cluster snapshot & will be more time-consuming in data restoration.
Options B & D are incorrect as this will launch a new DB cluster to a point in time & additional time will be required to restore data. This would be more time-consuming than using backtrack.
