Which of the following actions should you take?

You work as an administrator at Contoso.com. The Contoso.com network consists of a single domain
named Contoso.com. All servers on the Contoso.com network have Windows Server 2012 R2
installed.
Contoso.com has a server, named ENSUREPASS-SR13, which is configured as the primary DNS server
in the Contoso.com domain. Contoso.com has another server, named ENSUREPASS-SR14, which
makes use of ENSUREPASSSR13 for DNS queries.
You want to make sure that running nslookup.exe from ENSUREPASS-SR14 produces a result that
shows the proper name of the default server.
Which of the following actions should you take?

A.
You should consider creating a reverse lookup zone on ENSUREPASS-SR14.

B.
You should consider creating a forward lookup zone on ENSUREPASS-SR14.

C.
You should consider creating a reverse lookup zone on ENSUREPASS-SR13.

D.

Explanation:
When you start Nslookup from a command line, the following error message may be displayed: DNS
request timed out
timeout was x seconds
Can’t find server name for address xxx.xxx.xxx.xxx: Timed out
Default servers are not available
Default Server: UnKnown
Address: xxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the Internet Protocol (IP) address of the host on which you are attempting
to start
Nslookup.
CAUSE When Nslookup starts, it attempts to resolve the IP address of its host’s DNS server to its fully
qualified domain name (FQDN). If the DNS server does not respond or if the DNS server’s reverse
lookup zones do not contain a PTR record for the DNS server’s IP address, the error message is
displayed.
