You work as the network administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. Domain.com has its headquarters located in London and branch office located in Paris. All servers on the Domain.com network run Windows Server 2008 and all client computers run Windows Vista.
Domain.com currently makes use of a computer named CERTKILLER-SR01 which has the DNS Server role installed. During the course of the day you a network user named Rory Allen send a recursive query looking for the IP address of www.Weyland.com. Rory Allen has then discovered that the DNS server cannot find any local zones matching the requested domain name and the DNS server forwards the request to a root name server. Rory Allen wants to know what the root name server should reply with.
What would your reply be?
A.
The root name server would reply with the IP address of www.Weyland.com
B.
The root name server would reply with the IP address of the name server for the .com top-level domain.
C.
The root name server would reply with the IP address of the name server for the Weyland.com domain.
D.
The root name server would reply with the DNS name of the .com top-level domain.
Explanation:
The root name server has control over the root domain and has to reply with the IP address of a name server for the .com top-level domain. Upon receiving the IP address of the top-level domain the system should inquire for the Weyland.com address.
