CompTIA SecurityX (CAS-005) — Question 134

A Chief Information Security Officer is concerned about the operational impact of ransomware. In the event of a ransomware attack, the business requires the integrity of the data to remain intact and an RPO of less than one hour. Which of the following storage strategies best satisfies the business requirements?

Answer options

• A. Full disk encryption
• B. Remote journaling
• C. Immutable
• D. RAID 10

Correct answer: C

Explanation

The correct answer is C, Immutable, as it ensures that data cannot be altered or deleted, which is crucial during a ransomware attack to maintain integrity. Options A and D do not specifically address data integrity in the context of ransomware, while B, Remote journaling, may not guarantee the immediate integrity of data as effectively as an immutable storage solution.
