Your network contains a domain controller that is configured as a DNS server. The server hosts an Active
Directory-integrated zone for the domain.
You need to reduce how long it takes until stale records are deleted from the zone. What should you do?
A.
From the configuration directory partition of the forest, modify the tombstone lifetime.
B.
From the configuration directory partition of the forest, modify the garbage collection interval.
C.
From the aging properties of the zone, modify the no-refresh interval and the refresh interval.
D.
From the start of authority (SOA) record of the zone, modify the refresh interval and the expire interval.
Explanation:
Scavenging automates the deletion of old records. When scavenging is enabled, then you should also change
the no-refresh and refresh intervals of the aging properties of the zone else it may take too long for stale
records to be deleted and the size of the DNS database can become large and have an adverse effect on
performance.
