B. If the advertised distance of the nonsuccessor route is less than the feasible distance of best route,

then that route is identified as a feasible successor.

C. If the successor becomes unavailable, then the feasible successor can be used immediately without recalculating for a lost route.
D. The feasible successor can be found in the routing table.

E. Traffic will be load balanced between feasible successors with the same advertised distance. Answer: ABC

22. Which two statements are true about trust boundaries? (Choose two.)

B. Trust boundaries are used to determine which QoS mechanism will be applied to the traffic.

C. At the trust boundaries, the untrusted traffic will be marked with a new QoS value appropriate for the policy in place at the point where the traffic entered the campus network.

B. Wireless clients will be successfully authenticated only if their WEP key is configured as “adam”.

C. Wireless clients will first attempt to authenticate with MAC authentication and if this fails, EAP

authentication will be attempted.

D. Wireless clients will first attempt to authenticate with MAC authentication and if this succeeds, EAP

authentication will then be performed.

E. Wireless clients will attempt EAP authentication first, then MAC authentication.

Answer: C

25. In a comparison of an IPv4 header with an IPv6 header, which three statements are true? (Choose three.)
A. An IPv4 header includes a checksum. However, an IPv6 header does not include one.

B. A router has to recompute the checksum of an IPv6 packet when decrementing the TTL. C. An IPv6 header is half the size of an IPv4 header.
D. An IPv6 header has twice as many octets as an IPv4 header.

E. An IPv6 header is simpler and more efficient than an IPv4 header.

F. The 128bit IPv6 address makes the IPv6 header more complicated than an IPv4 header. Answer: ADE
