MCTS 70-640 AD Sites, Replication & Forest Trusts

Question 1

What is an Active Directory site in Windows Server 2008?

Accepted Answer

A logical representation of a well-connected IP network segment used to control replication and service location

Answer

An AD site represents a set of well-connected subnets, enabling AD to optimize replication traffic and guide clients to nearby domain controllers.

Question 2

Which object defines which domain controllers replicate with each other within a site?

Accepted Answer

Connection object

Answer

Connection objects define one-way replication partnerships between domain controllers; the KCC automatically creates them within a site.

Question 3

What is the role of the Knowledge Consistency Checker (KCC) in Active Directory?

Accepted Answer

Automatically generating and maintaining the replication topology by creating connection objects

Answer

The KCC is a built-in AD process that automatically builds and repairs the replication topology by creating and deleting connection objects on each DC.

Question 4

What is the default replication interval between sites when using a site link?

Accepted Answer

180 minutes

Answer

By default, inter-site replication via site links is scheduled every 180 minutes (3 hours), unlike intra-site replication which is near-real-time.

Question 5

Which protocol can be used for inter-site replication over slower or unreliable WAN links as an alternative to RPC?

Accepted Answer

SMTP

Answer

SMTP-based inter-site replication can be used for non-domain-naming-context partitions (like schema and configuration) over unreliable links where RPC is not feasible.
