Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 69

When an IPv6 enabled host boots, it sends a router solicitation (RS) message. An IPv6 router responds with a router advertisement (RA). Which two items are contained in the RA? (Choose two.)

Answer options

• A. IPv6 address for the host
• B. Lifetime of the prefix
• C. Prefixes for the link
• D. Keepalive timers
• E. Request for the local host IP address
• F. Any route advertisements it has received BC

Correct answer:

Explanation

The correct answers are B and C. The RA includes the lifetime of the prefix, which indicates how long the prefix is valid, and the prefixes for the link that inform the host about the network it is connected to. Options A, D, E, and F are incorrect because the RA does not provide an individual IPv6 address for the host, keepalive timers, requests for host IP addresses, or any external route advertisements.
