What is 'failback' in a disaster recovery context?
Answer: Moving operations from the DR site back to the restored primary site
Failback is the process of returning operations from the DR/secondary site to the original primary site once it has been repaired and validated after a disaster.
Which cloud DR strategy provides the lowest cost but the longest recovery time by storing data in the cloud without pre-provisioned compute resources?
Answer: Backup and restore
The backup and restore strategy stores data backups in the cloud but provisions no running compute, making it the cheapest option at the cost of longer recovery time when resources must be spun up.
The 'pilot light' cloud DR strategy differs from a warm standby primarily because:
Answer: Pilot light keeps only the minimal core infrastructure running, not a scaled version of the full environment
A pilot light keeps just the critical core components (such as a database replica) running in the cloud, requiring additional resources to be provisioned at failover, unlike a warm standby which runs a scaled-down but complete environment.
During a disaster, the Incident Commander's primary responsibility is to:
Answer: Coordinate and direct all response and recovery activities across teams
The Incident Commander serves as the overall coordinator for disaster response, directing teams, prioritizing recovery actions, and ensuring communication flows effectively across the organization.
What is the purpose of a 'recovery time objective' (RTO) gap analysis?
Answer: Comparing actual recovery times achieved in tests against the defined RTO targets
An RTO gap analysis compares tested recovery performance against the agreed RTO to identify where improvements are needed in recovery procedures or infrastructure.
Which DR document type focuses specifically on restoring IT infrastructure and systems rather than overall business continuity?
Answer: Disaster Recovery Plan (DRP)
The Disaster Recovery Plan (DRP) is specifically focused on the technical recovery of IT systems and infrastructure, while the BCP addresses the broader continuation of business operations.
An organization experiences a disaster at 2:00 PM. Their last backup completed at 10:00 AM. What is the actual data loss in hours?
Answer: 4 hours
Data loss equals the time between the last successful backup (10:00 AM) and the disaster event (2:00 PM), which is 4 hours — the actual recovery point achieved.
