Your network contains an Active Directory domain named contoso.com. The domain
contains three Active Directory sites. The Active Directory sites are configured as shown in
the following table.
The sites connect to each other by using the site links shown in the following table.
You need to design the Active Directory site topology to meet the following requirements:
Ensure that all replication traffic between Site2 and Site3 replicates through Site1 if a domain
controller in Site1 is available.
Ensure that the domain controllers between Site2 and Site3 can replicate if all of the domain
controllers in Site1 are unavailable.
What should you do?
A.
Delete Link2.
B.
Disable site link bridging.
C.
Delete Link3.
D.
Create one site link bridge.
D is incorrect.
Answer is A.
If Link2 is deleted, the default state of the sites is to bridge the connection. So Site 2 and 3 will be automatically bridged through Site 1.

– By default, all site links are bridged. For more information about disabling this option and its affects on intersite replication, see Related Topics.
D is correct. When you delete Link 2 you can not replicate if all of the domain
controllers in Site1 are unavailable.
answer is A
answer is D
A or D??
The question is incomplete, there should be more answer options:
A.
Delete Link1.
B.
Delete Link2.
C.
Delete Link3.
D.
Disable site link bridging.
E.
Create one site link bridge.
F.
Modify the cost of Link2.
G.
Create one SMTP site link between Site2 and Site3.
H.
Create one SMTP site link between Site1 and Site3. Create one SMTP site link between
Site1 and Site2.
F is the only one that makes any sense.
You can’t delete any of the site links. The options may be incomplete. I would increase the cost of the Site-2 to Site-3 link.
The KCC will figure out the DC in site 1 is down or can’t be contacted and on the fly change the replication paths.
Well, you CAN delete site links, but that’s beyond the point. To me, none of the options meet both the requirements. I would go for B, but then you need to change the link costs to control the replica flow.
