You need to recommend changes to the Active Directory site topology to support on the company’s planned changes.
What should you include in the recommendation?
A . A new site
B . A new site link bridge
C . A new site link
D . A new subnet
Answer: D
Explanation:
* Scenario:
The forest contains a child domain for each office. An Active Directory site exists for each office.
* Sites overview
Sites in AD DS represent the physical structure, or topology, of your network. AD DS uses network topology information, which is stored in the directory as site, subnet, and site link objects, to build the most efficient replication topology. The replication topology itself consists of the set of connection objects that enable inbound replication from a source domain controller to the destination domain controller that stores the connection object. The Knowledge
Consistency Checker (KCC) creates these connection objects automatically on each domain controller.
