642-902 Q&A – Implement an IPv6 based solution (16-20)

Section 4 – Implement an IPv6 based solution, given a network design and a set of requirements

QUESTION NO: 16
What is the IPv6 address FF02::2 used for? Select the best response.
A. all hosts in a local segment
B. all routers in a local segment
C. all hosts in a particular multicast group
D. all routers in an autonomous system
Answer: B

Explanation:
To identify all nodes for the node-local and link-local scopes, the following multicast addresses are defined:
FF01::1 (node-local scope all-nodes address)
FF02::1 (link-local scope all-nodes address)
To identify all routers for the node-local, link-local, and site-local scopes, the following multicast addresses are defined:
FF01::2 (node-local scope all-routers address)
FF02::2 (link-local scope all-routers address)
FF05::2 (site-local scope all-routers address)

QUESTION NO: 17

B. Interface Ethernet 0/0 has been configured with the ipv6 ospf authentication ipsec spi 500 md5 command.
C. OSPF version 3 is enabled to support IPv6.
D. The IP address of the designated router (DR) is FE80::A8BB:CCFF:FE00:6E00. E. This is the designated router (DR) on the Ethernet 0/0 link.
Answer: BC

B. The route table is cleared. Then the OSPF neighbors are reformed.
C. The shortest path first (SPF) algorithm is performed on the LSA database.
D. The OSPF database is repopulated. Then the shortest path first (SPF) algorithm is performed.
Answer: D
