A router receives information about network 192.168.10.0/24 from multiple sources. What will the router consider the most reliable information about the path to that network（）。

A. When a router receives a failure response, it stops querying authentication methods.

B. When a router receives an error response, it stops querying authentication methods.

C. If the router receives a failure response from an authentication method, it queries the next method.

D. The router does not differentiate between failure and error responses; the authentication process is always interrupted.

E. If it receives no response from the authentication method, a router will determine the error condition on its own; the router also has the option to proceed to the next method in a list if configured accordingly.

A. Forward the packet.

B. Fragment the packet.

C. Drop the packet silently.

D. Drop the packet and send an ICMPv6 message.

A. The destination is a host on another subnet, so the router will not forward the packet.

B. The destination is a host on the same subnet, so the router will forward the packet.

C. The destination is a broadcast address, so the router will not forward the packet.

D. The destination is a network address, so the router will forward the packet.

A. It performs a label pop operation and an IP lookup.

B. It performs a label swap operation and an IP lookup.

C. It sends an error message toward the egress router.

D. It sends an error message toward the ingress router.

An internet is a combination of networks connected by (71) .When a datagram goes from a source to a (72) ，it will probably pass many (73) until it reaches the router attached to the destination network．A router receives a (74) from a network and passes it to another network．A router is usually attached to several networks．When it receives a packet，to which network should it pass the packet？ The decision is based on optimization： Which of the available (75) is the optimum pathway？

A．modems

B．routers

C．switches

D．computers

A.The new IOS image is too large for the router flash memory.

B.The TFTP server is unreachable from the router.
