Your network contains an Active Directory domain named contoso.com. The physical
topology of the network is configured as shown in the exhibit.
Each office contains 500 employees.
You plan to deploy several domain controllers to each office.
You need to recommend a site topology for the planned deployment.
What should you include in the recommendation?
More than one answer choice may achieve the goal. Select the BEST answer.
Exhibit
A.
Five sites and one site link
B.
Three sites and three site links
C.
One site
D.
Five sites and three site links
Explanation:

Create a site for each LAN, or set of LANs, that are connected by a high speed backbone,
and assign the site a name. Connectivity within the site must be reliable and always
available.
This would mean 5 sites Site links are transitive, so if site A is connected to site B, and site B
is connected to site C, then the KCC assumes that domain controllers in site A can
communicate with domain controllers in site C. You only need to create a site link between
site A and site C if there is in fact a distinct network connection between those two sites.
This would mean 3 sitelinks
So answer is “Five sites and three site links”
Need an explanation on this one…
Why not 5 sites and 5 site links?
Or 4 at least??
Why only 3? I question the exhibit or answers on this.
Making 3 site links applies to the 5Mbps connection sites, since then can handle the extra replication traffic. ATL Sydney and ATL NY site links would not be efficient because of their low bandwidth.
That doesn’t make sense. If you don’t link Sydney and NY with the rest of the domain, how do they replicate?
A site link contain two or more sites.
Link 1: Atlanta-Washington-Boston
Link 2: Atlanta-Sydney
Link 3: Atlanta-NY
Basically how I understand it:
You obviously need to allocate 5 sites, because that is what you have… Atlanta is the main site, so you need (according to the diagram) 1 site link connecting it to NY, and another site link connecting it to Sydney.
So that’s 2 so far.
Now you have Washington and Boston, which as you can see are bridgedto each other… so we only need to create one site link for both of them, because replicated data from the main site (Atlanta) will replicate to the closest one/one with the least cost or whatever first (Lets assume this is Washington), and then it will replicate from Washington to Boston via their bridge connection.
