Your company has a main office and 50 branch offices. Each office is configured as an Active
Directory site. Each branch office site contains a domain controller. The main office site contains all
the global catalog servers in the forest. Each branch office contains a WAN link that connects to the
main office. You need to plan the deployment of new Mailbox servers to meet the following
requirements:
• Ensure that users in the branch offices can access their mailboxes if their local domain controller
fails
• Deploy the minimum number of Exchange servers
What should you include in the plan?
A.
One Mailbox server in each office and global catalog servers in each branch office
B.
One Mailbox server in each office and Universal Group Membership Caching in each branch office
C.
One Mailbox server in each branch office only
D.
Multiple Mailbox servers in the main office only
Explanation:
This is an interesting question however if you break it down it starts to make sense Main Office has
the Global Catalog Servers – not the Branch Offices Branch Offices connect to the main office via a
Wan Link While each branch office does have a domain controller they are not Global Catalog
Servers. Further there are 50 branch offices so it makes no sense to deploy a mailbox server in each
branch office or to have 50 Global Catalog Servers The best answer is D as this would meet the
requirement of deploying the least amount of Exchange Servers
