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 has the London and Paris office connected via a WAN link.
Domain.com additionally makes use of a computer in the London office named CERTKILLER- SR01 configured as the DNS server hosting a standard primary zone. During the course of the day you receive instruction from Domain.com to install a computer named CERTKILLER-SR02 in the Paris office configured as a DNS server. Domain.com additionally wants you to ensure that the DNS service on CERTKILLER-SR02 in the Paris office is able to update records and resolve queries in the event of a WAN link failure.
What should you do?
A.
You should consider having Domain.com converted to an Active Directory-integrated zone on CERTKILLER-SR01.
B.
You should consider having a new stub zone configured on CERTKILLER-SR01.
You should then set the forwarding option to CERTKILLER-SR02.
C.
You should consider having DNS on CERTKILLER-SR01 configured to forward request to CERTKILLER-SR02.
D.
You should consider having a secondary zone added on CERTKILLER-SR02 named Domain.com.
Explanation:
In the scenario you should ensure that CERTKILLER-SR01’s DNS service is able to update and resolve DNS queries if the WAN link fails. In addition you should have the mask converted to an Active Directory-integrated zone on CERTKILLER-SR01 as this eliminates the need for primary and secondary name servers as fault tolerance is built into Active Directory which in addition is a bonus when using dynamic DNS.
