Question 1

An auditor is evaluating the design of a disaster recovery plan (DRP). The organization uses a 'differential' backup strategy during the week and a 'full' backup on weekends. If the system crashes on Thursday afternoon, which files are required to restore the system to the most recent state?

Accepted Answer

Understand the difference between Incremental (changes since last backup of any kind) and Differential (changes since last FULL backup). Differential restoration is faster because you only need two files.

Question 2

What mistakes do candidates make on this CPA question?

Accepted Answer
