How does a data backup primarily contribute to business continuity?

By enabling the restoration of data after an incident, reducing downtime and data loss

By automatically detecting and correcting data corruption before it occurs

By ensuring that data is always available in real time without any interruption

By preventing all cyberattacks from reaching the network

What is the primary purpose of a data retention policy?

To define how long data must be kept and when it should be deleted

To ensure all data is kept indefinitely for future analysis

To encrypt all stored data to protect confidentiality

To provide real-time access to data for all employees

Which metric defines the maximum acceptable amount of data loss measured in time, such as minutes or hours, that an organization can tolerate?

Mean Time Between Failures (MTBF)

A company's backup administrator performs a test restore of the file server from last night's backup. The restore completes successfully, but when users try to open files, several files are corrupted. The backup software reported the backup as successful. What is the most likely cause and the best next step?

The backup media is faulty; replace the media and run the backup again.

The backup software is not compatible with the file server; switch to a different backup product.

The source files were already corrupted before the backup; verify the integrity of the source data and consider using application-aware backup.

The restore process is flawed; use a different restore method.

In a business continuity plan, what is the role of a data retention policy?

To reduce the number of backups needed by using only full backups

To ensure that data needed for recovery is available for the required period

To automatically fail over to a secondary site within seconds

To encrypt all data to prevent unauthorized access during a disaster
