A+ Backup Quiz: Full, Incremental or Differential?

1. Incremental backups grow in size each day because they store cumulative changes.

True

False

2. A backup strategy combining one full backup weekly with daily differential backups balances storage and recovery time.

True

False

3. For recovery purposes, a differential backup requires the full backup and the latest differential copy only.

True

False

4. Which backup type is best for daily backups when storage space is limited?

Full backup

Incremental backup

Differential backup

Synthetic backup

5. A typical backup rotation combines full, incremental, and differential backups for optimal balance.

True

False

6. Which backup approach requires restoring multiple backup sets to recover all data?

Full backup alone

Differential backup alone

Incremental backups with a full backup

Mirror backup

7. What does a full backup include?

All files and folders on the system

Only files changed since the last backup

Only files changed since the last full backup

Compressed versions of all system files

8. A full backup must be performed before taking incremental or differential backups.

True

False

9. What is the primary advantage of differential backups over incremental backups?

Faster backup time

Faster restore time

Lower storage requirements

No need for a full backup

10. A differential backup is faster to restore than an incremental backup.

True

False

11. Which backup strategy uses the least storage space over time?

Full backup only

Incremental backups after a full backup

Differential backups after a full backup

All three use equal space

12. To restore data after using incremental backups, you need the full backup plus all incremental backups in sequence.

True

False

13. Which backup type requires the most storage space initially?

Incremental backup

Differential backup

Full backup

Synthetic backup

Submit

15. An incremental backup captures which files?

All files on the system

Files modified since the last backup of any type

Files modified since the last full backup only

Files deleted in the current session

16. After a full backup, which backup type stores only changes since that full backup?

Incremental

Differential

Mirror

Both incremental and differential

17. Differential backups store the same data each time because they always reference the most recent full backup.

True

False

Submit

19. Which scenario best supports using incremental backups?

Minimal storage available, fast recovery needed

Ample storage available, minimal recovery time needed

Limited storage, longer recovery time acceptable

Single daily backup needed

Submit
