Your company has a single Active Directory forest that has an Active Directory domain named na.contoso.com. A server named Server1 runs the DNS Server server role. You notice stale resource records in the na.contoso.com zone. You have enabled DNS scavenging on Server1. Three weeks later, you notice that the stale resource records remain in na.contoso.com. You need to ensure that the stale resource records are removed from na.contoso.com.
What should you do?
A.
Stop and restart the DNS Server service on Server1.
B.
Enable DNS scavenging on the na.contoso.com zone.
C.
Run the dnscmd Server1 /AgeAllRecords command on Server1.
D.
Run the dnscmd Server1 /StartScavenging command on Server1.
Could someone explain why B is the right answer?
I would say the correct answer is D. per the question, scavenging is already turned on…
I agree with Chris.
Both Scavenging (server Level) and Aging/Scavenging (Zone Level) must be enabled. On Server level properties, under advanced, Enable automatic scavenging of stale records (which is enabled in the question), while the Zone settings MUST be enabled in Zone Properties/General Tab, Aging Button: enable Scavenge Stale Resource Records, by defaut both are disabled.
The answer should be B.
