問題文

A rotation function is triggered but its run fails, and the secret is never updated. Event Grid shows repeated delivery attempts over about two hours and then stops. What does this indicate?

選択肢

1. The notification will be published again when the secret is closer to its expiry, so the rotation has another chance to run before the value becomes unusable
2. The vault rotates the secret itself when the notified function fails, so the value is replaced even though the run did not complete
3. The retry window for the rotation notification has been exhausted, so the rotation must now be driven manually before the secret expires
4. The rotation notification is retried indefinitely with an increasing interval, so the rotation will eventually succeed once the underlying fault is fixed
