CompTIA Network+ (N10-008) — Question 537

Which of the following protocols uses Dijkstra's algorithm to calculate the LOWEST cost between routers?

Answer options

• A. RIP
• B. OSPF
• C. BGP
• D. EIGRP

Correct answer: B

Explanation

The correct answer is B, OSPF, as it utilizes Dijkstra's algorithm for calculating the shortest path. RIP uses distance-vector routing, BGP is a path vector protocol, and EIGRP employs a hybrid approach using DUAL, none of which rely on Dijkstra's algorithm.
