Which metric defines the maximum tolerable amount of data loss measured in time during a technology recovery scenario?
Answer: Recovery Point Objective (RPO)
RPO defines the maximum age of data that must be recovered from backup storage for normal operations to resume after a disaster.
During a technology recovery exercise, a team discovers their backup tapes cannot be read. What process failure does this most likely indicate?
Answer: Failure to test backup restoration procedures
Unreadable backup tapes typically reveal that restoration procedures were never tested, a critical gap in backup verification.
A hot site differs from a warm site primarily because a hot site:
Answer: Has pre-installed and configured systems ready for immediate use
A hot site has fully configured hardware and software with current data, enabling near-immediate failover with minimal activation time.
What is the primary purpose of a Technology Recovery Plan (TRP) in contrast to a broader Business Continuity Plan (BCP)?
Answer: To provide step-by-step technical instructions for restoring IT systems and infrastructure
A TRP focuses specifically on the technical steps to restore IT systems, whereas a BCP addresses broader business operational continuity.
Which storage replication method transmits data to a remote site only after the primary system acknowledges the write, risking data loss if the link fails?
Answer: Asynchronous replication
Asynchronous replication acknowledges writes at the primary before transmitting to the secondary, creating a potential data loss window if the link fails.
During technology recovery, which document should be consulted first to determine the sequence in which systems must be brought back online?
Answer: System dependency map
A system dependency map shows interdependencies between applications and infrastructure, guiding the correct restoration sequence.
A company's critical database server fails. The team restores from last night's backup (18 hours old). Which concept describes the 18-hour gap in recoverable data?
Answer: RPO breach
The 18-hour gap between the backup and the failure represents the actual data loss, which may exceed the organization's defined RPO.
