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

Real-time off-site replication is the most effective response strategy for a ransomware attack because it ensures that up-to-date copies of data are continuously replicated to a secure, remote location. This allows for faster recovery with minimal data loss. Incremental, full, and differential backups (B, C, D) are valuable but may not provide the immediacy and recency of data recovery needed during ransomware incidents.
