CCP Business Continuity & Disaster Recovery Flashcards

Which RAID level provides disk mirroring with no parity, offering full redundancy?

Answer: RAID 1

RAID 1 mirrors data across two drives, so if one fails the other contains an identical copy, providing full redundancy at the cost of 50% storage efficiency.

What is a failover cluster primarily used for?

Answer: Automatically switching to a standby system when the primary fails

A failover cluster monitors nodes and automatically redirects workloads to a surviving node when a failure is detected, minimizing downtime.

The 3-2-1 backup rule states you should have:

Answer: 3 copies of data, on 2 different media, with 1 stored offsite

The 3-2-1 rule recommends three total copies of data stored on two different types of media with one copy kept offsite for disaster protection.

Which term describes the process of testing disaster recovery plans through simulation without actually switching over production systems?

Answer: Tabletop exercise

A tabletop exercise is a discussion-based session where team members walk through a disaster scenario verbally to identify gaps without disrupting operations.

What is the primary purpose of a Business Continuity Plan (BCP)?

Answer: To ensure critical business operations continue during and after a disaster

A BCP outlines procedures and strategies to ensure essential business functions remain operational or resume quickly after a disruptive event.

Differential backup differs from incremental backup in that it:

Answer: Copies all data changed since the last full backup, regardless of intermediate backups

Differential backups always back up all changes since the last full backup, making restoration simpler (full + latest differential) but using more storage than incremental.
