Which of the following would be the MOST significant factor when choosing among several backup system alternatives with different restoration speeds?
When evaluating backup system alternatives with different restoration speeds, the most significant factor to consider is the Recovery Time Objective (RTO). RTO defines the maximum acceptable amount of time that a system can be down after a failure or disaster before resuming normal operations. Thus, the restoration speed of a backup system directly impacts the ability to meet this objective, making RTO the key factor.
should be C. restoration = RTO
The recovery time objective (RTO) specifies the maximum elapsed time to recover an application at an alternate site. The greater the RTO, the longer the process can take to be restored.
The question tries to trick you with the words "different restoration speeds", backups are related to RPO. Remember you can measure RPO based on timeline allowed for data loss i.e 0-1 hour time lag would require mirroring/real time replication as compared to 4- 24 hour time lag where you can use tape backups will have slower restoration speed for data lost.
The restoration speed of a backup system directly influences the organization's ability to meet its RTO. A backup solution with faster restoration speeds can help minimize downtime and ensure that critical systems and data are recovered within the specified RTO. While the Recovery Point Objective (RPO) (option B) is also an important consideration in backup system selection, it primarily relates to the acceptable data loss tolerance in the event of a disruption, rather than the speed of system restoration.
Agree with C, Speed>RTO (Time)
lowest RPO will ensure near to no data loss.. which is most rational approach.
so B is correct
