Which three actions should you perform?

DRAG DROP
Your network contains an Active Directory forest. The forest contains a single domain named
contoso.com.
The forest contains two Active Directory sites named Main and Branch1. The sites connect to each
other by using a site link named Main-Branch1. There are no other site links.
Each site contains several domain controllers. All domain controllers run Windows Server 2012 R2.
Your company plans to open a new branch site named Branch2. The new site will have a WAN link
that connects to the Main site only. The site will contain two domain controllers that run Windows
Server 2012 R2.
You need to create a new site and a new site link for Branch2. The solution must ensure that the
domain controllers in Branch2 only replicate to the domain controllers in Branch1 if all of the
domain controllers in Main are unavailable.
Which three actions should you perform?
To answer, move the three appropriate actions from the list of actions to the answer area and
arrange them in the correct order.

Answer:

Explanation:
SO…the first part of this answer is:
1. Create a new site object named Branch2
*When you create the new site Branch2 you will be prompted to associate it with a site link…right
now we only have one site link (Main-Branch1). Hit Finish
2. Remove Branch2 site from the Main-Branch1 Site Link
*In order to move a site into a new site link, you must first remove them from their previous site
link….In this case Branch2 was put in Main-Branch1 when we create the new site because we didn’t
have another site link to associate the new site with at the time we created it.
3. Create a new site link object named Main-Branch2
*When you create the site link object you will be asked to place the appropriate sites in this
link…choose Main and Branch 2
Because we are using Interstice topology replication, ISTG (similar to KCC with Intrasite) will build a
logical transitive connection path between all site links because site link bridge is enabled by default
and is a Microsoft best practice to leave this default.
By default a site link has a default cost of 100 so the Main-Branch1 site cost 100. Since we do not
have a site link established from Branch2 – Branch1, ISTG will create a logical patch that travels along
the Main-Branch2 site link (cost 100) and through Main-Branch1 site link(cost 100) to establish
replication connection in the event the least cost path goes down. Since the logical path =200,
Branch2 will only replicate with Branch1 if the site link to the Main Site goes down.
