Your network contains an Active Directory domainnamed adatum.com.
The domain contains a domain controllernamed DC1.
DC1has an IP addressof 192.168.200.100.
You need to identify the zone that contains the Pointer(PTR) record for DC1.
Which zone should you identify?
A.
adatum.com
5.168.192.in-addr.arpa
Netlogon
B.
_msdcs.adatum.com
0.5.168.192.in-addr.arpa
DNS Server
C.
100.168.192.in-addr.arpa
192.168.5.in-addr.arpa
Network Location Awareness
D.
200.168.192.in-addr.arpa
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.
QUESTION 3
Your network contains an Active Directory forestnamed adatum.com.
The DNS infrastructure fails.
You rebuild the DNS infrastructure.
You need to force the registration of the Active Directory Service Locator (SRV) records in DNS.
Which serviceshould you restarton the domain controllers?
Network Store Interface Service

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’sPTR (pointer) resource record.

The SRV resource records for a domain controller are important in enabling clients to locate the domain
controller. The Netlogon service on domain controllers registers this resource record whenever a domain
controller is restarted. You can also re-register adomain controller’s SRV resource records by restarting this
service from the Services branch of Server Manager or by typing net start netlogon. An exam question
might ask you how to troubleshoot the nonregistration of SRV resource records.
