CompTIA Cloud+ (CV0-002) — Question 16

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?

Answer options

• A. Restore the site at the new location within six hours by using backups from the failed public cloud site from eight hours earlier. Switch users from the failed site to the online regional public cloud site.
• B. Restore the site at the new location within two hours by using backups from the failed public cloud site from two hours earlier. Switch users from the failed site to the online regional public cloud site.
• C. Restore the site at the new location within eight hours by using backups from the failed public cloud site from six hours earlier. Switch users from the failed site to the online regional public cloud site.
• D. Restore the site at the new location within four and half hours by using backups from the failed public cloud site from a half hour earlier. Switch users from the failed site to the online regional public cloud site.

Correct answer: B

Explanation

Option B is the best choice because it allows for the recovery of the site within the RTO of four hours and utilizes backups from only two hours prior, which is within the RPO of eight hours. Other options either exceed the RTO or do not utilize the most recent backup data effectively, making them less optimal for disaster recovery.
