CompTIA Security+ study material · question 68 of 611

Which two backup properties most directly determine whether an organisation can recover from ransomware without paying? Choose two.

  1. Restores are tested rather than assumed to work
  2. Backups are stored in the same data centre for speed
  3. Backups are taken more frequently than daily
  4. The backups are offline or otherwise unreachable from the production network
Show the answer

Answer: A. Restores are tested rather than assumed to work
D. The backups are offline or otherwise unreachable from the production network

Reachable backups get encrypted with everything else, and an untested backup is an assumption rather than a control.
