Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 162

How is authentication handled with OSPFv3?

Answer options

• A. OSPFv3 for IPv6 authentication is supported by IPv6 IPsec.
• B. OSPFv3 for IPv6 authentication is supported by MD5 authentication.
• C. OSPFv3 for IPv6 authentication is supported by IPv4 IPsec.

Correct answer:

Explanation

The correct answer is A, as OSPFv3 uses IPv6 IPsec for authentication purposes, providing secure communication. Option B is incorrect because MD5 authentication is not applicable to OSPFv3, which does not support it. Option C is also wrong since OSPFv3 operates with IPv6, not IPv4 IPsec.
