Front Back
Domain controllers located in different sites will participate in intrasite replication.
False
Active Directory is only replicated when the name of an object has changed.
False
When replicating information between sites, Active Directory will designate a bridgehead server in each site to act as a gatekeeper in managing site-to-site replication.
True
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.
False
Site links connect two sites that communicate using the same protocol.
True
Active Directory __________ provide the means by which administrators can control replication traffic.
sites
Domain controllers located in different sites will participate in __________ replication.
intersite
How often does intersite replication occur by default?
15 minutes
When you install the forest root domain controller in an Active Directory forest, the Active Directory Installation Wizard creates a single site named __________.
Default-First-Site-Name
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.
replication topology
Replication within Active Directory will occur when which of the following conditions is met?
All of the above

added or removed from Active Directory, the value of an attribute has changed, or the name of an object has changed.
When replicating information between sites, Active Directory will designate a __________ server in each site to act as a gatekeeper in managing site-to-site replication.
bridgehead
What describes the amount of time that it takes for all domain controllers in the environment to contain the most up-to-date information?
convergence
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.
urgent
What process is responsible for selecting a bridgehead server and mapping the topology to be used for replication between sites?
Intersite Topology Generator
The primary goal of intersite replication is to minimize the usage of __________.
bandwidth
When configuring a site link object, which attribute allows the administrator to define the path that replication will take?
 cost
For both intrasite and intersite replication, what protocol does Active Directory use for all replication traffic?
RPC over IP
What is an alternative solution for intersite replication when a direct or reliable IP connection is not available?
SMTP
How often does replication occur in intersite replication?
180 minutes
The ISTG automatically assigns one server in each site as the bridgehead server unless you override this by establishing a list of __________ bridgehead servers.
preferred
What defines a chain of site links by which domain controllers from different sites can communicate?
site link bridge
What command-line tool used for monitoring Active Directory provides functionality that includes performing connectivty and replication tests?
dcdiag
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?
Repadmin
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?
 3
Intersite replication traffic is __________ by default to decrease the use of network bandwidth.
compressed
When you install the forest root domain controller in an Active Directory forest, the Active Directory Installation Wizard creates a single site named __________.
Default-First-Site-Name
Active Directory creates a replication __________ 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.
topology
Each domain controller maintains a local value called an update __________ number that keeps track of changes that are made at each DC and thus keeps track of which updates should be replicated to other domain controllers.
sequence
In addition to the USN, each Active Directory attribute has a(n) __________ ID associated with it that keeps track of how many times that attribute has been changed.
version
When replicating information between sites, Active Directory will designate a(n) __________ server in each site to act as a gatekeeper in managing site-to-site replication.
bridgehead
Domain controllers use __________ notification to inform one another when changes need to be replicated.
change
SMTP site links use __________ replication, meaning that each replication transaction does not need to complete before another can start because the transaction can be stored until the destination server is available.
asynchronous
All site links that use the same transport protocol are considered to be __________ by default, which means that a domain controller in any site can connect to a domain controller in any other site by navigating a chain of site links.
transitive
The default cost of any new site link is __________.
100
What are the means by which administrators can control replication traffic?
Active Directory sites
The forest root domain controller server object is placed within what folder of the Default-First-Site-Name site?
Servers
What joins together multiple sites?
site links
For each domain controller in the site, what does the KCC create between the domain controller and its new replication partners?
connection objects
How often does the KCC run and analyze the best path and placement for connection objects?
every 15 minutes
  Certain operations, such as a password change or an account lockout, will be transmitted using a special type of 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. What is this type of replication?
urgent replication
Active Directory uses what protocol for both intrasite and intersite replication?
RPC over IP, Remote Procedure Calls over Internet Protocol
What defines a chain of site links by which domain controllers from different sites can communicate?
site link bridge
What is the difference between intersite and intrasite replication?
Domain controllers that reside within the same site participate in intrasite replication. Domain controllers located in different sites will participate in intersite replication.
What three events cause replication to occur in Active Directory?
An object is added or removed from Active Directory. The value of an attribute has changed. The name of an object has changed.
If Active Directory cannot use the version ID as a tie-breaker for replication, what is done?
When two conflicting changes have the same version ID, the modification that took place later will be retained by Active Directory.
In terms of the KCC, what is the “Rule of Three?”
The “Rule of Three” states that no single domain controller should be more than three network hops away from any domain controller that can originate a change to the Active Directory database.
How does change notification work?
Each domain controller will hold a change for 45 seconds before forwarding it, after which it will transmit the change to each of its replication partners in 3-second intervals
To use the SMTP protocol to transmit replication traffic, what must you have?
an enterprise certification authority (CA) that is fully integrated with Active Directory
What is the syntax for the dcdiag command to check replication connections?
dcdiag /test:replications
