What is the purpose of the Intersite Topology Generator (ISTG)?
Answer: To calculate and create inter-site connection objects for replication between sites
The ISTG is one DC per site responsible for calculating the inter-site replication topology and creating bridgehead server connection objects.
What is a forest trust in Active Directory?
Answer: A two-way transitive trust between two separate AD forests
A forest trust creates a two-way transitive trust between the root domains of two separate AD forests, enabling cross-forest resource access.
Which type of trust shortens the authentication path between two domains in the same forest that are separated by multiple hops?
Answer: Shortcut trust
A shortcut trust directly connects two domains within the same forest to speed up authentication that would otherwise traverse multiple parent-child domain links.
What AD command-line tool is used to check replication status between domain controllers?
Answer: repadmin /replsummary
repadmin /replsummary provides a summary of replication status across all DCs, showing failures and lag times.
What does the 'repadmin /syncall' command do?
Answer: Forces all domain controllers to synchronize immediately with all replication partners
repadmin /syncall triggers immediate replication between a DC and all its partners, useful for pushing urgent changes across the environment.
Which attribute on a user object is used as the unique identifier that survives renames and moves across the AD forest?
Answer: objectGUID
objectGUID is assigned at object creation and never changes regardless of renames, moves, or domain migrations, making it the most stable unique identifier.
