問題文
A customer currently keeps only hourly snapshots on the production array. Which single addition improves their position against a ransomware event the most?
選択肢
- Turn on data at rest encryption for the volumes so that the attacker cannot read the contents of the snapshots after gaining access to them.
- Add a longer retention to the existing schedule so that older recovery points remain available for a much longer period of time.
- Make the existing snapshots immutable so that the credentials of an array administrator cannot be used on their own to remove them.
- Increase the frequency of the snapshots from hourly to every fifteen minutes so that less work is lost when an incident is detected.
