ISC2 CC Business Continuity and Disaster Recovery 2 — Questions and Answers
Question 1: What is a cold site in disaster recovery?
- A facility identical to the primary site
- An empty facility with basic infrastructure but no equipment (Correct answer)
- A cloud-based DR solution
- A temporary off-site storage location
Correct answer: An empty facility with basic infrastructure but no equipment
A cold site provides basic infrastructure (power, connectivity) but requires equipment and systems to be installed before operations can resume.
Question 2: Which term describes the process of returning to normal operations from a DR site?
- Failover
- Recovery
- Failback (Correct answer)
- Restoration
Correct answer: Failback
Failback is the process of returning operations from the disaster recovery site back to the primary site once it has been restored.
Question 3: What does MTTR stand for in availability planning?
- Maximum Throughput Time for Recovery
- Mean Time To Repair (Correct answer)
- Minimum Transfer Time Requirement
- Monthly Testing and Training Report
Correct answer: Mean Time To Repair
MTTR (Mean Time To Repair) is the average time required to repair a failed system or component.
Question 4: Which of the following is the MOST important outcome of a disaster recovery test?
- Minimal disruption to operations
- Testing all systems simultaneously
- Documenting lessons learned and improvements needed (Correct answer)
- Involving only IT staff
Correct answer: Documenting lessons learned and improvements needed
Documenting lessons learned is critical because it captures improvements needed to strengthen the DR plan for future real incidents.
Question 5: What does a warm site offer that a cold site does not?
- Better temperature control for equipment
- Pre-installed equipment and connectivity but not live data (Correct answer)
- Fully replicated live data and systems
- Only network connectivity with no servers
Correct answer: Pre-installed equipment and connectivity but not live data
A warm site has pre-installed equipment and network connectivity but requires data restoration before operations can fully resume.
Question 6: What does Mean Time Between Failures (MTBF) measure?
- The time required to repair a failed system
- The average time between system failures (Correct answer)
- The maximum acceptable downtime
- The frequency of scheduled maintenance
Correct answer: The average time between system failures
MTBF measures the average time between failures for a system or component and is used to assess overall reliability.
