摘要：对于【网络管理员】软考考试而言，试题无疑是最重要的学习资料之一。在软考备考过程中，吃透试题、掌握试题所考知识点、熟悉试题的出题思路，对我们提升分数的效果是最明显的，通过对试题的反复练习，还可以查漏补缺。今天，给大家带来【网络管理员2022下半年模拟一上午题】部分试题的详解，一起来看看吧~



1、Routing protocols use different techniques for assigning (71) to individual networks. Further, each routing protocol forms a metric aggregation in a different way. Most routing protocols can use multiple paths if the paths have an equal (72) . Some routing protocols can even use multiple paths when paths have an unequal cost In either case, load (73) can improve overall allocation of network bandwidth. When multiple 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 (74) across the possible routes in a manner proportional to the route metrics. Per-destination load balancing distributes packets across the possible routes based on (75). 
A、 bracketing
B、 balancing
C、 downloading
D、 transmitting

答案:B
答题解析:

各种路由协议使用不同的技术来为网络赋予度量值。进一步说，每一种路由协议都形成了不同的度量汇聚模式。大部分路由协议在各个通路具有相等费用时可以使用多个通路。某些路由协议甚至在各个通路费用不相等时也可以使用多个通路。在上述任何一种情况下，负载均衡都可以改进网络带宽的全局分配。当使用多个通路时，可以使用多种方法来分配分组。两种最通常的机制是按分组进行负载均衡和按目标进行负载均衡。按分组进行负载均衡是指按照路由度量的比例向各个可能的路由上分配分组。按目标进行负载均衡是指根据目标向各个可能的路由上分配分组。
