Certified Information Systems Security Professional (CISSP) — Question 179

Which dynamic routing protocol is BEST suited for a dispersed campus network utilizing Internet Protocol version 6 (IPv6) addresses?

Answer options

• A. Open Shortest Path First (OPSF) version 3
• B. Enhanced Interior Gateway Routing Protocol (EIGRP)
• C. Border Gateway Protocol (BGP) version 4
• D. Routing Information Protocol (RIP) version 2

Correct answer: A

Explanation

Open Shortest Path First (OPSF) version 3 is specifically designed to support IPv6, making it the best choice for a campus network using this addressing scheme. Enhanced Interior Gateway Routing Protocol (EIGRP) and Routing Information Protocol (RIP) version 2 do not natively support IPv6, and while Border Gateway Protocol (BGP) version 4 can work with IPv6, it is primarily used for routing between autonomous systems rather than within a campus environment.
