Routing.protocols use different techniques for assigning【S1】to individual networks.Further,each routing protocol forms a metric aggregation in a different.way.Most routing protocolscan use muh.iple paths if the paths have an equal【S2】.Some routing protocols can evenuse multiple paths when paths have an unequal cost.In either ease,load【S3】can improveoverall allocation of network bandwidth.When mulliple paths are used.there are several ways to distribute the packets.The two most common mechanisms are per—packet load balancing and per—destination load balancing.Per—packet load balancing distributes the【S4】across the possi-ble routes in a manner proportional to the route metrics.Per-destination load balancing distributes packets across the possible routes based on【S5】.

【S1】

A.calls

B.metrics

C.1inks

D.destinations

参考答案和解析
正确答案:B
解析:路由协议使用各种技术来确定到达不同网络的跳数。此外,每个路由协议用不同的方法形成一个跳数聚集。大多数路由协议可以使用多条路径,如果它们代价相等,一些路由协议甚至可以在路径代价不等时也使用多条路径。在任何情况下,负载均衡可以提高整体的网络带宽分配。当使用多条路径时,有几种方法分配数据包。最常见的两种机制是按包负载平衡和按目的地负载平衡。按包负载均衡是按路由跳数成比例地分配数据包。按目的地负载平衡是基于目的地来分配数据包。

    To assess how well a student is performing relative to his or her own previous performance,a teacher would use__________ assessment.

    A.criterion-referenced
    B.individual-referenced
    C.norm-referenced
    D.peer

    答案:B
    解析:
    考查教学评价。教学评价标准包括目标参照性评价、常模参照性评价和个体参照性评价。对一个学生与其之前的表现相比作评价.属于个体参照性评价。故选B。

  • 第3题:

    To assess how well a student is performing relative to his or her own previous performance,a teacher should use_________assessment.

    A.criterion-referenced
    B.individual-referenced
    C.norm-referenced
    D.peer

    答案:B
    解析:
    考查教学评价。教学评价可分为目标参照性评价、常模参照性评价和个体参照性评价。目标参照性评价(Criterion-referenced assessment)是以具体体现教学目标的标准作为依据,确定学生是否达到标准以及达到的程度如何的一种评价方法。常模参照性评价(Norm-referenced assessment)是依据学生个人的成绩与规定的一群人(如班级、年级、全国的同龄人等)中其他人的成绩相比较来评价和决定学生成绩优劣的一种方法。而不考虑他是否达到教学目标的要求。个体参照性评价(Individual-referenced assessment)是将一个学生的表现与其之前的表现相比所作出的评价。故选B。
