A city defines RPO of 1 hour and RTO of 4 hours for the building-permit system and wants the lowest ongoing DR cost that still meets those targets. Which DR strategy fits?
Select an answer to reveal the explanation.
Short Explanation
An hour of data and four hours to get back online is the classic “restore from backups” neighborhood—not the always-on twin-city price tag.
Full Explanation
Backup and restore is appropriate when RPO/RTO allow hours of recovery and minimize steady-state DR cost. Active-active and warm standby lower RTO at higher continuous cost; a full-capacity pilot light misstates the pattern. Matching strategy to stated RPO/RTO is the Associate-level decision.
