第1题：

What does a router do if it has no EIGRP feasible successor route to a destination network and the successor route to that destination network is inactive status?()

A. It routes all traffic that is addresses to the destination network to the interface indicates in the routing table.

B. It sends a copy of its neighbor table to all adjacent routers.

C. It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network.

D. It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.


参考答案：C

第2题：

Traditional network layer packet forwarding relies on the information provided by network layer （） protocols, or static routing, to make an independent （本题）decision at each hop within the network. The forwarding （）is based solely on the destination （）IP address. All packets for the same destination follow the same path across the network if no other equal-cost paths exist. Whenever a router has two equal-cost （）toward a destination, the packets toward the destination might take one or both of them, resulting in some degree of load sharing.
