AZ-802 Deploy and Manage AD DS Practice Question
You have three Active Directory sites: SiteA, SiteB, and SiteC. SiteA is connected to SiteB with a cost of 50. SiteB is connected to SiteC with a cost of 50. There is no direct link between SiteA and SiteC. If 'Bridge all site links' is enabled, what is the effective replication cost between SiteA and SiteC?

Correct answer & explanation
✓
100
Active Directory uses site link costs to determine the most efficient path for replication. When 'Bridge all site links' is enabled (the default), Active Directory can calculate a transitive path between sites that are not directly connected. The total cost is the sum of the costs of the individual links that make up the path.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
100
Why this is correct
Because 'Bridge all site links' is enabled, the KCC can route replication from SiteA through SiteB to reach SiteC. The total cost is calculated by adding the SiteA-SiteB link cost (50) to the SiteB-SiteC link cost (50), resulting in an effective transitive replication cost of 100 for the entire route.
- ✗
50
Why it's wrong here
A cost of 50 would only be possible if there were a direct site link between SiteA and SiteC with that specific value. In a transitive routing scenario, the costs of all segments in the path must be added together, and there is no mechanism in Active Directory to ignore the cost of intermediate hops.
- ✗
Replication is impossible without a direct link.
Why it's wrong here
This is incorrect because Active Directory supports transitive replication. As long as 'Bridge all site links' is enabled or manual site link bridges are created, domain controllers can replicate across multiple hops, provided there is a continuous chain of site links connecting the source and destination sites in the forest.
- ✗
0
Why it's wrong here
A cost of 0 is not used for site links, as the minimum default cost is 1. Even within a site, replication has an implied cost, and across sites, the cost is used to prefer faster or more reliable links. A value of 0 would prevent the KCC from making meaningful decisions about the topology.
