You have an Active Directory domain named contoso.com. You have a domain controller named
Server1 that is configured as a DNS server. Server1 hosts a standard primary zone for contoso.com.
The DNS configuration of Server1 is shown in the exhibit.
You discover that stale resource records are not automatically removed from the contoso.com zone.
You need to ensure that the stale resource records are automatically removed from the
contoso.com zone.
What should you do?
A.
Set the scavenging period of Server1 to 0 days.
B.
Modify the Server Aging/Scavenging properties.
C.
Configure the aging properties for the contoso.com zone.
D.
Convert the contoso.com zone to an Active Directory-integrated zone.
Explanation:
Scavenging or aging as it is also known as automates the deletion of old records. When scavenging is
disabled, these records must be deleted manually or the size of the DNS database can become large
and have an adverse effect on performance. In the exhibit it shows that scavenging is enabled on
Server1, thus you should configure the aging properties for the zone.
B & C is basically the same answer….

Not really, check yourself the contoso zone aging properties:

B and C are not the same.
Be cautious that B goes with “Server…” while C goes with “… contoso.com ZONE”.
The answer is C (ZONE).
