1.
The guiding principle involved in the
KCC’s selection of replication partners and its creation of replication
objects is the “Rule of Four,” which states that no single domain
controller should be more than four network hops away from any domain
controller that can originate a change to the Active Directory database.
Correct Answer
B. False
2.
What defines a chain of site links by which domain controllers from different sites can communicate?
Correct Answer
A. Site link bridge
Explanation
A site link bridge defines a chain of site links by which domain controllers from different sites can communicate. In cases in which there is a centralized site that connects two branch sites via site links, the site link bridge creates a direct link between the branch sites using the total cost of both site links to the central site.
3.
Replication within Active Directory will occur when which of the following conditions is met?
Correct Answer
D. All of the above
Explanation
Replication within Active Directory will occur when an object is added or removed from Active Directory, the value of an attribute has changed, or the name of an object has changed.
4.
Active Directory __________ provide the means by which administrators can control replication traffic.
Correct Answer
B. Sites
Explanation
Active Directory sites are the means by which administrators can control replication traffic.
5.
How often does replication occur in intersite replication?
Correct Answer
D. 180 minutes
Explanation
The default replication frequency for a new site link is 180 minutes, but it can be configured to take place as frequently as every 15 minutes and as infrequently as once per week.
6.
Certain operations, such as a password
change or an account lockout, will be transmitted by using __________
replication, which means that the change will be placed at the
“beginning of the line” and applied before any other changes that are
waiting to be replicated.
Correct Answer
A. Urgent
Explanation
Certain operations, such as a password change or an account lockout, will be transmitted using urgent replication, which means that the change will be placed at the “beginning of the line” and will be applied before any other changes that are waiting to be replicated.
7.
What describes the amount of time that
it takes for all domain controllers in the environment to contain the
most up-to-date information?
Correct Answer
B. Convergence
Explanation
Active Directory convergence describes the amount of time that it takes for this process to take place so that all domain controllers in the environment contain the most up-to-date information.
8.
How often does intersite replication occur by default?
Correct Answer
C. 15 minutes
Explanation
Domain controllers located in different sites will participate in intersite replication. Intersite replication occurs on a scheduled basis (every 15 minutes by default).
9.
When you install the forest root domain
controller in an Active Directory forest, the Active Directory
Installation Wizard creates a single site named __________.
Correct Answer
D. Default-First-Site-Name
Explanation
When you install the forest root domain controller in an Active Directory forest, the Active Directory Installation Wizard creates a single site called Default-First-Site-Name, which you can see in the Active Directory Sites and Services tool.
10.
Domain controllers located in different sites will participate in intrasite replication.
Correct Answer
B. False
11.
For both intrasite and intersite replication, what protocol does Active Directory use for all replication traffic?
Correct Answer
C. RPC over IP
Explanation
For both intrasite and intersite replication, Active Directory uses Remote Procedure Calls over Internet Protocol (RPC over IP) by default for all replication traffic. RPC is commonly used to communicate with network services on various computers, whereas IP is responsible for the addressing and routing of the data. RPC over IP replication keeps data secure while in transit by using both authentication and encryption.
12.
Domain controllers located in different sites will participate in __________ replication.
Correct Answer
A. Intersite
Explanation
Domain controllers located in different sites will participate in intersite replication. Intersite replication occurs on a scheduled basis (every 15 minutes by default).
13.
What command-line tool can be used to
manually create a replication topology if site link bridging is
disabled if the network is not fully routed?
Correct Answer
C. Repadmin
Explanation
Repadmin is a command-line tool used to manually create a replication topology if site link bridging is disabled if the network is not fully routed.
14.
Active Directory is only replicated when the name of an object has changed.
Correct Answer
B. False
15.
Active Directory creates a __________
with the idea that all writeable domain controllers in a domain should
communicate Active Directory information to each other, in addition to
communicating forest-wide information with other domains.
Correct Answer
A. Replication topology
Explanation
Active Directory creates a replication topology with the idea that all writeable domain controllers in a domain should communicate Active Directory information to each other, in addition to communicating forest-wide information with other domains. Sites and subnets defined within Active Directory will dictate the path used by replication traffic on the network, as well as form the basis for how Active Directory information is distributed.
16.
What process is responsible for selecting a bridgehead server and mapping the topology to be used for replication between sites?
Correct Answer
D. Intersite Topology Generator
Explanation
To create a replication topology in a multisite network, one domain controller within each site runs the Intersite Topology Generator (ISTG), which is a process responsible for selecting a bridgehead server and mapping the topology to be used for replication between sites.
17.
What is an alternative solution for intersite replication when a direct or reliable IP connection is not available?
Correct Answer
B. SMTP
Explanation
Simple Mail Transport Protocol (SMTP) is an alternative solution for intersite replication when a direct or reliable IP connection is not available. SMTP, a member of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, is the standard protocol used for message transfer, such as email.
18.
What command-line tool used for
monitoring Active Directory provides functionality that includes
performing connectivty and replication tests?
Correct Answer
A. Dcdiag
Explanation
Dcdiag is a command-line tool used for monitoring Active Directory. When run from a command prompt, this tool can perform connectivity and replication tests, report errors that occur, report DNS registration problems, analyze the permissions required for replication, and analyze the state of domain controllers within the forest.
19.
The ISTG automatically assigns one
server in each site as the bridgehead server unless you override this
by establishing a list of __________ bridgehead servers.
Correct Answer
B. Preferred
Explanation
The ISTG automatically assigns one server in each site as the bridgehead server unless you override this by establishing a list of preferred bridgehead servers. The advantage of administratively assigning a preferred bridgehead server list is that you can determine which servers have the best processing power for handling replication traffic.
