問題文

A secret referenced from a configuration setting was rotated, but the application continues to receive the old value long after. Which cause fits?

選択肢

1. The vault serves the previous value for a fixed grace period after a rotation so that in-flight clients are not disrupted, and the period has not elapsed yet
2. The reference is pinned to a specific version, so it keeps resolving to the value that version holds
3. The configuration store does not support references to secrets, so the value that was copied in at setup time is what the application keeps receiving
4. Purge protection retains the old value and keeps designating it as the current version until the retention period for the deleted version has passed
