HOTSPOT
Your network contains an Active Directory domain named contoso.com. The domain
contains a domain controller named Server1. Server1 has an IP address of
192.168.200.100.
You need to view the Pointer (PTR) record for Server1.
Which zone should you open in the DNS snap-in to view the record?
To answer, select the appropriate zone in the answer area.

Reverse lookup: This occurs when a client computer knows the IP address of another
computer and requires its hostname, which can be found in the DNS server’s PTR (pointer)
resource record.

MCTS 70-640 Cert Guide: Windows Server 2008 Active Directory, Configuring (Pearson IT
Certification, 2010) page 45/730
You are configuring a reverse lookup zone for your network, which uses the Class C network
address range of 192.168.5.0/24. Which of the following addresses should you use for the
reverse lookup zone?
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 both incorrect.
