Your network consists of a single Active Directory domain. The domain contains three domain
controllers and one DNS server. You plan to deploy Exchange Server 2010. You need to recommend
a DNS implementation that provides redundancy if a DNS server fails. What should you include in the
recommendations?
A.
Active Directory integrated DNS server
B.
DNS forwarding
C.
integrated DNS and WINS
D.
multiple MX records
Explanation:
With 3 domain controller all running the DNS service this will provide good fault tolerance if a single
server fails. Keep in mind that Exchange Server also requires Global Catalog Servers – so you should
have more than one on the network.
