CCP Business Continuity & Disaster Recovery Flashcards

Which technology replicates data to a secondary location in real time to support near-zero RPO?

Answer: Synchronous replication

Synchronous replication writes data simultaneously to both primary and secondary locations, ensuring zero or near-zero data loss but requiring low-latency links.

An organization's DR plan assigns a priority of Tier 1 to its order processing system. This means the system:

Answer: Must be recovered first because it is most critical to business operations

Tier 1 in DR tiering identifies mission-critical systems that must be restored first because their outage causes immediate, severe business impact.

What is 'data vaulting' in the context of disaster recovery?

Answer: Electronically transmitting backup data to a secure offsite storage facility

Electronic vaulting (data vaulting) automatically transfers backup data over a network to an offsite facility, eliminating the need for physical media transport.

Mean Time To Recovery (MTTR) measures:

Answer: The average time required to restore a failed system to full operation

MTTR is the average elapsed time from when a failure occurs until the system is fully operational again, used to evaluate the efficiency of recovery processes.

Which of the following best describes a 'warm site' in disaster recovery?

Answer: A facility with hardware pre-installed but requiring data restoration before use

A warm site has hardware and network connectivity in place but lacks current data, requiring restoration from backups before normal operations can resume.

Which metric measures the average time a system operates before experiencing a failure?

Answer: MTBF (Mean Time Between Failures)

MTBF quantifies system reliability by calculating the average operational time between failures, helping organizations predict maintenance needs.
