Your network consists of one Active Directory domain.
All domain controllers run Windows Server 2008 R2 and are configured as global catalog servers. The relevant portion of the network is configured as shown in the exhibit.
The Bridge all site links option is enabled.
You are designing a failover strategy for domain controller availability.
You need to ensure that client computers in SiteH only authenticate to DC1 or DC2 if DC8 fails.
What should you do?
A.
Change the B-H site link cost to 50.
B.
Remove the global catalog server attribute from DC3, DC4, DCS, DC6, DC7, and DC8.
C.
Disable the Bridge all site links option. In SiteB, install a new writable domain controller that runs Windows Server 2008 R2.
D.
Prevent DC3, DC4, DC5, DC6, DC7, and DC8 from registering generic (non-site-specific) domain controller locator DNS records.
