You have a DNS server named Server1 that runs Windows Server 2012 R2. On Server1,
you create a DNS zone named contoso.com.
You need to specify the email address of the person responsible for the zone.
Which type of DNS record should you configure?

A.
Start of authority (SOA)

B.
Host information (HINFO)

C.
Mailbox (MB)

D.
Mail exchanger (MX)

Explanation:
A SOA-record defines the responsible person for an entire zone, but a zone may contain
many individual hosts / domain names for which different people are responsible. The RPrecord type makes it possible to identify the responsible person for individual host names
contained within the zone.
