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
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.
Refresh Interval
Time in seconds that a secondary name server should wait between zone file update checks.
Retry Interval
Time in seconds that a secondary name server should wait before trying to contact the primary name server again after a failed attempt to check for a zone file update.
Expiry Interval
Time in seconds that a secondary name server will treat its zone file as valid when the primary name server cannot be contacted.
