CompTIA Network+ (N10-008) — Question 640

Which of the following routing technologies uses a successor and a feasible successor?

Answer options

• A. IS-IS
• B. OSPF
• C. BGP
• D. EIGRP

Correct answer: D

Explanation

The correct answer is D, EIGRP, as it uniquely utilizes both a successor and a feasible successor to enhance route selection and provide redundancy. The other protocols, IS-IS, OSPF, and BGP, do not have the concept of feasible successors in their routing mechanisms.
