And this lesson will be talking about characteristics of ADT as her application.
And here it's brief overview.
We'll take a look at multiple master replication Pooler application store and forward to application
then will review data store partition and attribute level replication and some words about collision
detection and management.
Now it's important that you understand that you can make changes from any domain controller in the domain
except for read only domain controllers and that those changes can replicate to all other domain controllers.
Also it's important that you could compare this with a single master replication model in which you
can make changes on one domain controller only think of benefits and disadvantages result from using
a multiple master replication model.
You should know that this model results in a more complicated replication process than the single master
model but it provides more redundancy and scalability.
An effective edit is replication design ensures that each partition on a domain controller is consistent
with the replicas of that partition that are hosted on other domain controllers typically not all domain
controllers have exactly the same information in their replicas at any particular moment because change
is secure to the partition constantly however aided yes replication ensures that all changes to a partition
transfer to all the replicas of the partition aided is replication balances accuracy or integrity and
consistency or convergence with performance.
This keeps replication traffic to a reasonable level.
Now let's see the key characteristics of aided yes replication multiple master replication and a domain
controller accept and rotate seek and initiate and commit a change to.
Edit Is this poor whites fault tolerance and eliminates dependency on a single domain controller to
maintain the directory store separations.
Another characteristic is Boola replication a domain controller requests or pools changes from other
domain controllers a domain controller cannot defy its replication partners that it has changes to the
director or asks its partners to see if they have changes to the directory.
However ultimately the target domain controller requests and pulls the changes itself.
Next stop is store and forward replication a domain controller can bool changes from one replication
partner and then make those changes available to another replication partner.
For example domain controller B can pull changes initiated by domain controller a then domain controller
C can pull the changes from domain controller B.
This helps balance the application load for domains that contain several domain controllers.
Then we have data stored partitioning our domains domain controllers host the domain name in context
for their domains which helps minimize replication particulary in multiple domain forests.
The Domain Controller is also host corpus of schema and configuration partitions which are replicated
forest wide.
However changes in configuration and schema partitions are much less frequent than in the domain partition
by default.
Other data include an application directory partitions and the partial attributes set which is the global
catalogue do not replicate to every domain controller in the forest.
You can enable replication to be universal by configuring all the domain controllers in a forest as
global catalog servers.
Next up is automatic generation of an efficient and robust replication topology by default aided is
configure as an effective multi directional replication topology so that the loss of one domain controller
does not embed or corrupt replication aid is automatically updates this topology as domain controller
of SA read it removed or moved between sites.
Next up is attribute level replication.
When an objects attribute changes only that attribute and minimal method data describe and that attribute
replicates the entire object does not replicate except on this initial creation for multi well you'd
attribute such as account names in the member of attribute of a group account only changes to actual
names replicate and not the entire list of names and other key characteristics of active directory application
as distinct control of interest site replication.
You can control a replication between sites.
Next stop is collision detection and management.
It's possible to modify an attribute on two different domain controllers within a single replication
window thereby creating a conflict.
However this is rare.
If this secures you must reconcile the two changes aided yes US has the resolution algorithms that satisfy
most all scenarios.
