A company performs nightly full backups and hourly transaction log backups. During a quarterly restore test, they successfully restored the full backup but could not apply the transaction log backups. The error indicates that the log backup chain is broken. What is the most likely cause and the appropriate corrective action?

The backup software is not compatible with the database; upgrade the backup software.

The log backups were taken from a different database copy; restore the correct log backup sequence.

The full backup is too old; perform a new full backup.

The log backups are corrupted; switch to differential backups.

A company has a backup strategy that includes nightly full backups and weekly test restores. The RPO is 24 hours and the RTO is 8 hours. During a recent disaster, they discovered that the backup software had been silently failing for 3 days, and the last successful backup was 4 days old. Which improvement would most directly prevent this from happening again?

Switch to a different backup software.

Perform test restores more frequently, such as daily.

Implement automated backup monitoring and alerting.

Increase the frequency of full backups to twice a day.

An e-commerce company experiences peak traffic from 8 AM to 10 PM. Their database changes rapidly during peak hours. The RPO is 1 hour and the RTO is 6 hours. They currently run a full backup at 2 AM and a differential backup at 6 AM daily. Which scheduling change best meets the RPO without disrupting business hours?

Add transaction log backups every hour during peak hours and every 4 hours off-peak.

Run a full backup every 6 hours throughout the day.

Keep the current schedule and accept the RPO of 24 hours.

Run the differential backup at 2 AM instead of 6 AM.

A company's backup verification process only checks that backup jobs complete successfully. During a disaster recovery exercise, they discover that a database backup cannot be restored because the backup software did not capture the database in a consistent state. Which improvement to the verification process would best prevent this issue?

Perform application-aware restore tests that validate database consistency

Check the backup log for errors after each job

Increase the frequency of full backups

Use a different backup software vendor
