CCP CCP Business Continuity & Disaster Recovery 2 — Questions and Answers
Question 1: Which RAID level provides disk mirroring with no parity, offering full redundancy?
- RAID 1 (Correct answer)
- RAID 0
- RAID 5
- RAID 6
Correct 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.
Question 2: What is a failover cluster primarily used for?
- Automatically switching to a standby system when the primary fails (Correct answer)
- Load balancing across multiple servers
- Encrypting data during transmission
- Archiving old data to cold storage
Correct 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.
Question 3: The 3-2-1 backup rule states you should have:
- 3 copies of data, on 2 different media, with 1 stored offsite (Correct answer)
- 3 backups per day, 2 onsite, 1 encrypted
- 3 sites, 2 hot and 1 cold
- 3 RPOs, 2 RTOs, 1 BIA
Correct 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.
Question 4: Which term describes the process of testing disaster recovery plans through simulation without actually switching over production systems?
- Tabletop exercise (Correct answer)
- Full interruption test
- Parallel test
- Checklist review
Correct 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.
Question 5: What is the primary purpose of a Business Continuity Plan (BCP)?
- To ensure critical business operations continue during and after a disaster (Correct answer)
- To document all IT assets and their replacement costs
- To define employee roles during non-emergency operations
- To schedule routine maintenance windows
Correct 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.
Question 6: Differential backup differs from incremental backup in that it:
- Copies all data changed since the last full backup, regardless of intermediate backups (Correct answer)
- Copies only data changed since the last backup of any type
- Compresses data more aggressively than incremental backups
- Runs less frequently than incremental backups
Correct 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.
