  • 第1题：

    What is the meaning of the default value of the EIGRP variance command of 1? ()

    A. Only the path that is the feasible successor should be used.

    B. Load balancing is disabled on t his router.

    C. The router only performs equal - cost load balancing on all paths that have a metric greater than 1

    D. The router performs equal - cost load balancing.


    参考答案：D

  • 第2题：

    Refer to the exhibit. Router B and router C are performing mutual redistribution between OSPF and EIGRP, and their default metrics are configured the same. Router D has equal cost paths to networks where both paths are not r eally equal cost. For example, network 172.16.54.0 shows equal cost through both router B and router C, though in reality the cost is greater using router C. Other routers, though not shown, are connected to the 172.16.54.0 and 172.16.55.0 networks, and the same issues exist to those routers and the networks connected to them. What can be done so that data will be routed along the most optimal path in the network? （）

    A. Redistribute connected interfaces on router B and router C

    B. Set the maximum nu mber of equal cost paths to1 in all routers

    C. When redistributing EIGRP into OSPF, set the external metric type to type E1

    D. Adjust the default metrics in router B and router C so that the values are different in each router

    E. None of these solut ions will fix the problem. Migrate to a single dynamic routing protocol


    参考答案：E

  • 第3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.
