An enterprise telemetry cluster suffers a database volume corruption on Friday at 10:00 AM. The disaster recovery strategy specifies a full system backup executed every Sunday at midnight, supplemented by daily differential backups executed every night at 23:00 from Monday through Thursday. Which TWO of the following recovery steps must be performed to restore the database to its latest possible state prior to the failure while minimizing operational restore steps? (Select TWO.)
- Restore the full system backup image from Sunday midnight.Answer
- Restore the differential backup created on Thursday at 23:00.Answer
- CRestore each daily backup file sequentially from Monday night through Thursday night.
- DRestore the Monday differential backup prior to applying the Thursday differential backup.
- EApply the Thursday differential backup directly to the bare-metal host without initializing the base image.
Answer
Restoring the full system backup image from Sunday midnight and restoring the differential backup created on Thursday at 23:00.
Differential backups record all data modified since the last full baseline backup. Therefore, restoring a system utilizing a differential strategy requires exactly two files: the baseline full backup (Sunday) and the most recent differential backup (Thursday at 23:00).
