You have a DNS server named DNS1 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)
Answer: B
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.
