Which DNS record type do Windows clients use to locate domain controllers for a specific AD DS domain?
Answer: SRV (Service) records
Active Directory relies on SRV records registered in DNS (e.g., _ldap._tcp.) so clients can dynamically discover domain controllers.
What is the role of Active Directory Sites and Services in controlling application replication traffic?
Answer: It defines site links with cost and schedule to control inter-site replication timing and bandwidth usage
Site links define the cost, replication interval, and schedule for inter-site replication, allowing administrators to align AD replication with WAN constraints.
What does the Knowledge Consistency Checker (KCC) automatically generate to ensure AD DS replication connectivity?
Answer: Connection objects between domain controllers
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.
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?
Answer: Global Catalog server
Global Catalog servers store a partial replica of all objects in the forest, enabling universal group membership lookups required during cross-domain logon.
An administrator enables Universal Group Membership Caching (UGMC) at a branch office site. What problem does this solve?
Answer: It allows branch users to log on without contacting a Global Catalog server across the WAN
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.
What replication protocol does Active Directory use by default for intra-site replication between domain controllers?
Answer: RPC over IP (uncompressed, low-latency)
Within a site, AD replication uses RPC over IP without compression because the high-speed LAN makes compression overhead unnecessary, and replication is triggered immediately.
Which AD DS FSMO role holder is responsible for maintaining referential integrity for group memberships that span domain boundaries in a forest?
Answer: Infrastructure Master
The Infrastructure Master updates cross-domain object references (phantoms) so that group membership displays correctly when members reside in different domains.
