Your network contains two DNS servers named Server1 and Server2 that run Windows Server 2012 R2. Server1 hosts a primary zone for contoso.com. Server2 hosts a secondary zone for contoso.com. You need to ensure that Server2 replicates changes to the contoso.com zone every five minutes.
Which setting should you modify in the start of authority (SOA) record?
A . Retry interval
B . Expires after
C . Minimum (default) TTL
D . Refresh interval
Answer: D
Explanation:
By default, the refresh interval for each zone is set to 15 minutes. The refresh interval is used to determine how often other DNS servers that load and host the zone must attempt to renew the zone.
