Correct answer: A

Cache locking is a new feature available if your DNS server is running Windows Server 2008 R2. When you enable cache locking, the DNS server will not allow cached records to be overwritten for the duration of the time to live (TTL) value. Cache locking provides for enhanced security against cache poisoning attacks.
