Certified Chief Information Security Officer (CCISO) — Question 81

Which of the following strategies provides the BEST response to a ransomware attack?

Answer options

• A. Real-time off-site replication
• B. Daily incremental backup
• C. Daily full backup
• D. Daily differential backup

Correct answer: A

Explanation

Real-time off-site replication is the best response to a ransomware attack because it ensures that data is continuously backed up in real-time, minimizing potential data loss. The other options, while useful, do not provide the same level of protection since they rely on scheduled backups that could leave data vulnerable to encryption by ransomware during the intervals between backups.
