ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 143

Which type of routing protocol relies on the shortest path tree?

Answer options

• A. path-vector
• B. hybrid routing
• C. link-state
• D. distance-vector C

Correct answer:

Explanation

The correct answer is C, link-state, as it builds a complete view of the network topology and calculates the shortest path to each node. The other options, such as path-vector and distance-vector protocols, use different mechanisms for routing decisions that do not rely on a shortest path tree.
