CSA Backup and Disaster Recovery 2

Question 1

Which backup strategy copies only files that have changed since the last FULL backup, regardless of whether a previous incremental backup was taken?

Accepted Answer

Differential backup

Answer

A differential backup copies all data changed since the last full backup, making it independent of other differential backups.

Question 2

What is the primary purpose of a hot site in disaster recovery planning?

Accepted Answer

To provide a fully operational duplicate environment with minimal failover time

Answer

A hot site is a fully equipped, always-on duplicate facility that allows near-immediate failover during a disaster.

Question 3

An administrator needs to restore a single deleted file from three weeks ago. The organization uses weekly full and daily incremental backups. What is the minimum number of backup sets needed?

Accepted Answer

Up to 3 (the full plus each incremental up to the deletion date)

Answer

With incrementals, you need the last full backup plus every incremental from that point up to the day before deletion.

Question 4

What does the term 'journaling' refer to in the context of database backup and recovery?

Accepted Answer

Recording all transactions so the database can be replayed to a consistent state

Answer

Database journaling records every transaction, enabling point-in-time recovery by replaying or rolling back those transactions.

Question 5

Which RAID level provides disk striping with parity distributed across all drives, offering both performance and fault tolerance?

Accepted Answer

RAID 5

Answer

RAID 5 stripes data and distributes parity across all member drives, tolerating a single drive failure.
