CompTIA Network+ (N10-007) — Question 625

Which of the following routing conventions is known as a link-state protocol?

Answer options

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

Correct answer: D

Explanation

The correct answer is OSPF, as it is a link-state routing protocol that uses a method of maintaining a complete map of the network topology to make routing decisions. In contrast, RIP and EIGRP are distance-vector protocols, while BGP is a path-vector protocol, which means they operate differently than link-state protocols.
