A.       Only one IPv6 address is assigned per node.

B.       Only one IPv6 address can be assigned to each interface.

C.       Each host can auto configure its address without the aid of a DHCP server.

Correct Answer: C

 

 

QUESTION 226

What does the command clear ipv6 ospf process accomplish?

 

A.       The OSPF adjacencies are cleared and initiated again.

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.

 

Correct Answer: D

 

 

QUESTION 227

B.       Specific addresses can be selected using an ACL.

C.       Specific addresses can be selected using a route map.

D.      Specific addresses can be selected using a prefix list.

 

Correct Answer: A

 

 

QUESTION 228

Which statement is true about the command ipv6 ospf 1 area 0?
