Lesson 3
Working with Active Directory Sites
Knowledge Assessment
Fill in the Blank
Complete the following sentences by writing the correct word or words in the blanks provided.
1.The amount of time that it takes for a change to be replicated to all domain controllers in an environment is called _convergence_.
2.The default __cost__ of any new site link is 100.
3.Intersite replication uses __compressed__ traffic to reduce the impact to bandwidth on corporate WAN links.
4.The KCC creates a(n) __ dual counter-rotating ring__ to allow replication to take place in the opposite direction in the event that a single domain controller in the replication topology fails.

5.The purpose of the KCC is to create a(n) __replication topology__ between multiple domain controllers within a site as well as between sites.
6.By default, all Active Directory site links are __transitive__.
7.When Active Directory detects a replication conflict in which two objects have been modified nearly simultaneously, the first attribute that Active Directory will use as a tie-breaker is the __version ID__.

8.Active Directory will designate a(n) __bridgehead server__ within each site to manage intersite replication activity.
9.The minimum __frequency__ that you can assign to a site link is 15 minutes.
10.Within a single site, domain controllers will use __change notification__ to inform other DCs that intrasite replication needs to take place. Multiple Choice
Circle the letter that corresponds to the best answer
1.The KCC is responsible for calculating intrasite replication partners. During this process, what is the maximum number of hops that the KCC will allow between domain controllers?
a.2
b.3
c.4
d.5
The built-in algorithm used by the KCC ensures that any Active Directory site is no more than three hops away from any other Active Directory site. If sites are added to Active Directory, the KCC can create additional connection objects to maintain this “3 hop” rule. 2.Replication that occurs between sites is called ____________ replication.

a.Local
b.Remote
c.Intersite
d.Intrasite
Intrasite replication takes place between domain controllers within a single Active Directory site. Intersite replication takes place between domain controllers contained within different Active Directory sites. 3.Company XYZ is a national company with locations in Detroit, Minneapolis, Phoenix, and Dallas. There are two connections between Detroit and Minneapolis. The first is a T-1 link and the second is a 128-Kbps link. When setting up the site links for replication, what should you do to ensure that the 128-Kbps link is used only if the T-1 is unavailable?

a.Set a cost of 1 for the T-1 and a cost of 5 for the 128-Kbps link.
b.Set a cost of 5 for the T-1 and 1 for the 128-Kbps link.
c.Leave the costs at their default value of 100.
d.Change the schedule manually to disallow replication on the 128-Kbps link until it is needed.
When selecting between multiple site links connecting the same two sites, the KCC compares site link costs and selects the one with the lower cost. Only if that site link is not available will it use the site link with a higher configured cost. 4.You are the administrator for a network that has several sites. There is a site link from the main headquarters to each remote site for file transfer and replication purposes. You have been asked to create five new users on the network, and several of the users need immediate access to network applications. When asked by your manager how long replication of these new accounts will take, what is your response?

a.Replication occurs every 180 minutes by default.
b.Replication occurs at 15-minute intervals.
c.Replication occurs as soon as the account is added.
d.Replication occurs only between 12:00 am and 6:00 am.
The default replication interval for intersite...
