You have a DNS server named DN51 that runs Windows Server 2012 R2.
On DNS1, you create a standard primary DNS zone named adatum.com.
You need to change the frequency that secondary name servers will replicate the zone from DNS1.
Which type of DNS record should you modify?
A.
Name server (NS)
B.
Start of authority (SOA)
C.
Host information (HINFO)
D.
Service location (SRV)
Explanation:
The time to live is specified in the Start of Authority (SOA) record
Note: TTL (time to live) – The number of seconds a domain name is cached locally before expiration and return
to authoritative nameservers for updated information.
Answer is B. But the explanation is wrong – The SOA Refresh interval is used to control how old a copy of a zone should be on a secondary before being refreshed from the primary:
