CV0-003 Question #314: Real Exam Question with Answer & Explanation
The correct answer is C: Restore the site at the new location within eight hours by using backups from the failed public. RPO defines the maximum acceptable age of backup data used in recovery, and RTO defines the maximum time allowed to restore service - a valid recovery plan must satisfy both constraints.

Question
A CSA needs to bring a client's public cloud site online at another location in the same region after a disaster. The RPO is eight hours, and the RTO is four hours. Which of the following is the BEST way to accomplish this goal?
Options
- ARestore the site at the new location within six hours by using backups from the failed public cloud
- BRestore the site at the new location within two hours by using backups from the failed public cloud
- CRestore the site at the new location within eight hours by using backups from the failed public
- DRestore the site at the new location within four and half hours by using backups from the failed
Explanation
RPO defines the maximum acceptable age of backup data used in recovery, and RTO defines the maximum time allowed to restore service - a valid recovery plan must satisfy both constraints.
Common mistakes.
- A. Restoring within six hours does not match the eight-hour RPO boundary and does not satisfy both recovery objectives as defined in the scenario.
- B. Restoring within two hours is faster than necessary but does not correspond to the stated eight-hour RPO, making it an imprecise fit for the defined recovery requirements.
- D. Restoring within four and a half hours exceeds the RTO of four hours, meaning the system remains offline longer than the maximum allowable downtime and violates the recovery time constraint.
