Database Backup and Data Integrity Quiz

1. Which backup storage location provides the fastest recovery time in case of data loss?

Offsite cloud storage

Tape archival system

Local network attached storage (NAS)

External hard drive at headquarters

2. True or False: Backup encryption is optional and does not affect data integrity compliance.

True

False

3. True or False: Transaction isolation in ACID prevents one user's changes from being visible to another until the transaction commits.

True

False

4. True or False: A hot standby system requires manual failover activation during a disaster.

True

False

5. True or False: Data integrity constraints can prevent invalid data from being entered into a database.

True

False

6. True or False: A differential backup requires all previous incremental backups to perform a complete restore.

True

False

Submit

10. What is the purpose of transaction logs in database backup and recovery?

To record all database changes for point-in-time recovery

To monitor user login activity

To compress backup files automatically

To encrypt sensitive data

11. What is the primary purpose of a full database backup?

To create a complete copy of all database files at a specific point in time

To record only changes made since the last backup

To compress database files for storage efficiency

To automatically repair corrupted data

12. A transaction that follows the ACID property and either completes entirely or not at all demonstrates which principle?

Consistency

Atomicity

Isolation

Durability

13. What is RPO in the context of database recovery?

Recovery Process Optimization

Recovery Point Objective—the maximum acceptable data loss

Replication Protocol Operation

Remote Procedure Override

14. Which disaster recovery strategy involves maintaining a synchronized copy of the database at a remote location?

Cold standby

Warm standby

Hot standby

Offline backup

15. In data integrity, what does a checksum verify?

That data has not been accidentally altered or corrupted

That all users have accessed the database

That backup files are encrypted

That transactions were committed in order

16. What is the main advantage of differential backups over incremental backups?

They require less storage space

They are faster to create

Restore requires only the last differential backup plus the last full backup

They automatically compress data

17. A database maintains data integrity through constraints. Which is NOT a common constraint type?

Primary key constraint

Foreign key constraint

Unique constraint

Random constraint

18. What does ACID stand for in database transactions?

Authentication, Consistency, Integrity, Durability

Atomicity, Consistency, Isolation, Durability

Accuracy, Confidentiality, Integration, Delivery

Access, Control, Integrity, Distribution

19. In database recovery, RTO stands for Recovery Time Objective. What does this measure?

The maximum acceptable downtime before system restoration

The amount of data loss tolerable in a disaster

The physical location of backup storage

The encryption strength of backup files

20. Which backup type records only data changes since the last full backup?

Full backup

Incremental backup

Snapshot backup

Archive backup
