QUESTION 245

What action will be taken by a Cisco IOS router if a TCP packet, with the DF bit set, is larger than the egress interface MTU?

QUESTION 248

Which three statements correctly describe the purpose and operation of IPv6 RS and RA messages? (Choose three.)

 

A.

Both IPv6 RS and RA packets are ICMPv6 messages.

B.

IPv6 RA messages can help host devices perform stateful or stateless address autoconfiguration; RS messages are sent by hosts to determine the addresses of routers.

C.

RS and RA packets are always sent to an all-nodes multicast address.

D.

RS and RA packets are used by the duplicate address detection function of IPv6.

E.

IPv6 hosts learn connected router information from RA messages which may be sent in response to an RS message.

F.

RS and RA packets are used for IPv6 nodes to perform address resolution that is similar to ARP in IPv4.

 

Correct Answer: ABE
