The only domain controllers that communicate with the other sites.
What is a bridgehead server?
100
Replication between domain controllers in different sites across a WAN. Intersite replication is considered request-pull replication.
What is intersite replication?
100
One site that designated as the hub and communicates with each of the other sites.
What is hub and spoke replication topology?
100
A special type of AD DS container object that provides the connection between the logical AD DS infrastructure—forests, domains, and organizational units—and the physical network infrastructure—cables, routers, and WAN links.
What is a site?
100
The primary reason for creating multiple AD DS sites is to conserve this on relatively slow and expensive WAN connections.
What is bandwidth?
200
The first site object that is created when you create a new forest.
What is Default-First-Site-Name?
200
This creates a bidirectional connection between the source domain controller and the replica domain controller.
What is the Knowledge Consistency Checker (KCC)?
200
This represents the physical connection between remote sites.
What is the site link object?
200
When you determine the Active Directory topology, you need to consider this.
What is the location of the domain controllers?
200
Intrasite replication topology is generated by this.
What is the KCC?
300
A notification given by source domain controllers within a site to their replica domain controllers, notifying them that it has new changes that can be replicated.
What is change notification?
300
Each site maintains connections to every other site.
What is a full mesh topology?
300
This consists of one or more IP subnets connected by a high-speed link and typically defined by a geographical location.
What is a site?
300
This is one of the most critical aspects of the physical AD DS topology.
What is replication?
300
By using these three things, site links are optimized to provide the fastest and cheapest replication possible between two sites.
What is scheduling, configured replication intervals, and costs?
400
A Windows server that stores a replica of the account and security information for the domain and defines the domain boundaries.
What is a domain controller?
400
The time it takes for changes to propagate to all the domain controllers in the enterprise—can be relatively slow.
What is the latency period?
400
This occurs during change notification between domain controllers located within that site.
What is intrasite replication?
400
Active Directory domains, trees, and forests are a _____ representation of your network organization.
What is logical?
400
Intersite replication traffic can occur these two ways.
What is RPC over IP or via Simple Mail Transfer Protocol (SMTP)?
500
This is responsible for managing the inbound replication connection objects for all bridgehead servers in the site in which it is located.
What is the Inter-site Topology Generator (ISTG)?
500
A change from any domain controller that is automatically propagated to all other domain controllers.
What is multimaster replication?
500
The value of a site link that does not have to represent an actual monetary value; it is significant only in relation to the value applied to the other links.
What is site link cost?
500
A connection between two site links that renders them transitive.
What is a site link bridge object?
500
Consider using this in an area that needs to look up, search, or access Active Directory information in an environment that might not be totally secure.
