Your network contains an Active Directory domainnamed contoso.com.
The domain contains a domain controllernamed Server1.
Server1has anIP addressof 192.168.200.100.
You need to view the Pointer (PTR) record for Server1.
Which zoneshould you open in the DNS snap-into view the record?
To answer, select the appropriate zone in the answer area.

A.
5.168.192.in-addr.arpa

B.
0.5.168.192.in-addr.arpa

C.
192.168.5.in-addr.arpa

D.
192.168.5.0.in-addr.arpa
The reverse lookup zone contains octets of the network portion of the IP address in reverse sequence and uses
a special domain name ending in in-addr.arpa.Thus the correct address is 5.168.192.in-addr.arpa. You do not
use the host portion of the IP address, so 0.5.168.192.in-addr.arpa is incorrect. The octets must be specified in
reverse sequence, so the other two choices are bothincorrect.
