Term
______ replication takes place within a single well connected location.
Definition
Intrasite
Term
______ replication allows AD to replicate over WAN links to remote locations.
Definition
Intersite
Term
T/F
Active Directory sites are the means by which Administrators can control traffic.
Definition
True
Term
By default, _____ replication occurs every 15 minutes.
Definition
Intersite
Term
How often does intrasite replication take place?
Definition
Almost immediately following a change in AD.
Term
T/F
All types of replication traffic is compressed.
Definition
False;
Intrasite replication is not compressed and intrasite replication is.
Term
ADs logical structure can be viewed through ADUC, and its physical structure can be viewed in AD ______
Definition
Sites and Services
Term
Sites are defined by well-connected ____ _____
Definition
IP subnets
Term
What purpose do sites serve?
Definition
They organize the replication process by defining the servers that will replicate with eachother by using either intersite or intrasite replication.
Term
[Fact]
When logging on, hosts will query DNS servers for site information in order to know what DC they will authenticating to.
Definition
[Fact]
AD sites are independant of the logical structure of AD meaning that a single site can contain multiple domains and a domain can span multiple sites
Term
[Tip]
Define sites prior to promoting Domain Controllers.
Definition
This will ensure that the clients are attempting authentication to the correct server.
Term
What is the primary goal if intersite replication?
Definition
To minimize bandwidth usage
Term
When configuring the frequency of AD intersite replication, what is the default value?
Definition
180 minutes or 3 hours
Term
What two protocols are used by AD replication?
Definition
RPC over IP and SMTP
Term
All replication traffic uses which protocol by default?
Definition
RPC over IP
Term
When a direct or reliable IP connection is not available, _____ can be used in place of RPC over IP.
Definition
SMTP
Term
SMTP site links use ______ replication.
Asynchronous
Compressed
Encrypted
Definition
Asynchronous
Term
T/F
SMTP site link replication transactions do not need to be complete before another segment of data is sent.
Definition
True;
This is known as Asynchronous replication
Term
T/F
SMTP can replicate domain directory partitions
Definition
False;
SMTP can only replicate configuration, schema, and application directory partitions. Additionally, SMTP requires an Enterprise Certificate Authority that is fully integrated with AD.
Term
Which partitions in AD can the SMTP protocol be used to replicate?
Definition
Configuration, Schema, and Application directory partitions
Term
Which protocol should be used when replicating between different domains across slow WAN links?
Definition
SMTP
Term
What type of replication utilizes BHS'?
Definition
Intersite replication
Term
What type of replication utilizes the KCC?
Definition
Intrasite replication
Term
What does designating a BHS do to a network?
Definition
It minimizes bandwidth consumption by only replicating from one source server to others outside of the network
Term
T/F
A BHS is automatically chosen without Adminstrative action.
Definition
True;
The BHS is chosen automatically by the ISTG
Term
T/F
You can have only one BHS per site.
Definition
False;
You will have AT LEAST one BHS per site but you can configure multiple BHS servers, especially to serve separate partitions.
Term
Which replication protocol requires an enterprise CA and why?
Definition
SMTP because the replication traffic is sent out whether it is being recieved or not and when it is received, the recevinig server should be able to trust the source hence the CA
Term
When is it a better idea to manually configure site link bridges instead of letting the ISTG do it for you?
Definition
When the network you are administering is not fully routed
and
When there are many sites in the network that are not at the FFL of server2003 or better, to prevent overloading the ISTG
Term
A chain of site links by which domain controllers from different sites can communicate are known as what?
Definition
site link bridges
Term
T/F
You can force the KCC to work after a malfunction by selecting Sites and services>Sites>correspondingsitename>NTDS setttings>All tasks> and select Check Replication Topology, the same folder destination is true if you want to force replication earlier than the scheduled time.
Definition
True
Term
What two well known command line tools are made available for monitoring and manipulating replication after the implementation of AD DS.
Definition
dcdiag and repadmin
Term
This command line tool can perform connectivity and replication tests; reporting the errors that are discovered
Definition
dcdiag
Term
This command line tool can report DNS registration problems
Definition
dcdiag
Term
This command line tool can analyze the permissions required for replication
Definition
dcdiag
Term
analyze the state of Domain Controllers within the forest
Definition
dcdiag
Term
This command line tool can view the replication topology from the perspective of each domain controller
Definition
repadmin
Term
This command line tool can manually create a replication topology if site link bridging is disabled (because the network is not fully routed)
Definition
repadmin
Term
This command line tool can force replication between domain controllers
Definition
repadmin
Term
This command line tool can view replication metadata (which is the combination of the actual data and the up-to-date USN information). This is helpful in determining the most up to date information before seizing a FSMO role
Definition
repadmin
Term
The default _____ of any new site link is 100
Definition
cost
Term
All site links are considered transitive when they
Definition
all share the same protocol
Term
When AD detects a replication conflict in which two objects have been modified nearly simultaneously, the first Attribute that will be used as a tie breaker is the ____. The second? Third?
Definition
Version ID
2nd time-stamp
3rd GUID
Term
The minimum _____ that you can assign to a site link is 15 minutes.
Definition
Frequency
Term
Sites and subnets defined within AD dictate the ____ used by replication traffic on the network
Definition
path
Term
Each Domain Controller maintains a USN that keeps track of changes that are made at each DC and thus keeps track of changes that need to be replicated out to other DCs throughout the forest. What does USN stand for?
Definition
Update Sequence Number
Term
The KCC works by creating replication partners and _____ _____ between said DC and its new partners
Definition
Connection objects
Term
_____ _____ ______ allows for AD replication in WS2k8 to repplicate only information that was changed as opposed to the entire list, whether it was changed or not (like with WS2k3)
Definition
LVR (Link Value Replication)
Term
What is "The Rule of Three"?
Definition
The Rule of Three states that no Domain Controller should be more than 3 network hops away from any other Domain Controller that can originate a change to the Active Directory database
Term
Application Directory partitions, Schema partitions, Configuration partitions, and domain partitions are referred to as ____ ____
Definition
Naming contexts
Term
T/F
Once a manual replication connection is configured and activated, all automatic replication connections are then ignored.
Definition
True
