MCTS 70-640 Technology & Digital Applications 5

Question 1

Which DNS record type do Windows clients use to locate domain controllers for a specific AD DS domain?

Accepted Answer

SRV (Service) records

Answer

Active Directory relies on SRV records registered in DNS (e.g., _ldap._tcp.<domain>) so clients can dynamically discover domain controllers.

Question 2

What is the role of Active Directory Sites and Services in controlling application replication traffic?

Accepted Answer

It defines site links with cost and schedule to control inter-site replication timing and bandwidth usage

Answer

Site links define the cost, replication interval, and schedule for inter-site replication, allowing administrators to align AD replication with WAN constraints.

Question 3

What does the Knowledge Consistency Checker (KCC) automatically generate to ensure AD DS replication connectivity?

Accepted Answer

Connection objects between domain controllers

Answer

The KCC runs on every DC and automatically creates and removes connection objects to maintain a ring topology within sites and spanning-tree topology between sites.

Question 4

Which AD DS component must be present in each domain in a forest for users in that domain to successfully log on to resources in other domains?

Accepted Answer

Global Catalog server

Answer

Global Catalog servers store a partial replica of all objects in the forest, enabling universal group membership lookups required during cross-domain logon.

Question 5

An administrator enables Universal Group Membership Caching (UGMC) at a branch office site. What problem does this solve?

Accepted Answer

It allows branch users to log on without contacting a Global Catalog server across the WAN

Answer

UGMC caches universal group membership on a local DC so users can log on even if the WAN link to a Global Catalog server is slow or unavailable.
