题目

试题:The metric assigned to each network depends on the type of protocol.Some simple protocol,like RIP,treats each network as equals.The （ ） of passing through each network is the same;
A.number
B.connection
C.diagram
D.cost
试题:it is one （ ） count.So if a packet passes through 10 network to reach thedestination,the total cost is 10 hop counts.Other protocols,such as OSPF,allow the administrator to assign a cost for passing through a network based on the type of service required.
A.process
B.hop
C.route
D.flow
然后说下为什么选这个答案的原因

答案

1.cost,2.hop
大致意思：依靠协议类型为每个网段设计度量值.一些简单的协议,像RIP,对待每个网段都是平等的,经过每个网段的开销都是一样的.
以一跳计数,因此,如果一个包经过10个网段到达目标时,总的开销是10跳.另外的协议,比如OSPF,允许管理员根据服务类型需要为经过的网段设计开销.
翻译有点生硬,答案从上下文可知.
