Free Isaca Cybersecurity Audit Certificate Actual Exam Questions - Question 1 Discussion

A - gotta apply all the increments, so it adds up time-wise.

A imo, because restoring incrementals means starting with the full backup, then applying each incremental in sequence, which definitely drags the process out more than the others.

Option A usually takes the longest because you have to restore the full backup first, then each incremental backup in order. Differential (D) just needs the last full backup plus the latest differential.

I’m with the idea that B is a bit vague since offsite just means where the backup is stored, not how it’s done. So it doesn’t really fit as a backup method like the others. Incremental (A) definitely takes longer because you’re piecing together multiple sets. Differential (D) is simpler since it only grabs changes since the last full backup, so less overhead than incremental. Full (C) is fastest since it’s all there in one go. So, does it make sense to rule out B just for being a location term rather than a distinct backup method?

A. Incremental backups do take the longest to restore because you have to go through the last full backup plus every incremental backup after that. Differential backups (D) are faster since you only need the full backup and the last differential, and full backups (C) are fastest for restoration but take more time to create. Offsite backup (B) is just about where the data is stored, not the backup type itself, so it doesn’t directly impact restoration time in this context.

It’s A because you restore the last full backup plus all incremental backups.

Option A, incremental backup usually takes the longest to restore since you have to restore multiple sets of data.
