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 in the London office as the network DNS server.
Domain.com currently has the network configured with each office containing a file server used to access and store files. During the course of the day you receive complaints from network users complaining about the long wait when connecting to network resources. You later checked the WAN bandwidth and discovered no problems. Domain.com requested that you ensure the network users are able to access resources quickly as possible.
What should you do? (Choose two)
A.
You should consider having a DNS server installed in the Paris office.
B.
You should consider having a secondary zone configured in the Paris office.
C.
You should consider having forwarders configured in the Paris office.
D.
You should consider having the Paris office configured with a standard primary zone.
Explanation:
You should then ensure the secondary zone used the London office DNS server as a master.
You should then configure the Paris office DNS server to point to the DNS server in the London office.
In the scenario you should have a DNS server installed in the Paris office with a separate zone for the office as a single zone can become overburdened consuming the bandwidth and we should ensure that the network users receive access to resources as quickly as possible.
The Paris office should be configured with a secondary zone which uses the London office DNS server as a master. You should then consider having copies of the zone file distributed among several name servers to ensure quick access to network resources.
You should finally know that changes made to the primary zone are replicated to the secondary zone which is known as a zone transfer. You should also not confuse that a name server is necessarily the primary or secondary server because a DNS server might host the primary zone for a specific portion of the Organization name space and a secondary for another name space. You should then note that you would not be able to have forwarders set in the Paris office which means you would not be able to resolve names outside your own network.
