     For most students, the most difficult part of any exam is the actual studying.Typically, there is so much
material to study that students begin to delay, putting off studying until the night before.After a latenight cram session, students arrive at the exam tired and feeling dazed by large amounts of information they've tried to
absorb.The easiest way to study, for an exam, and avoid the cram sessions, is to make a study plan.
The first step to making a study plan is to decide whether you want to study alone or in a group.When
planning study times and organizing study sessions for a group, the needs and schedules of the group are a
factor.As a result, you must decide whether you will be studying with a group before continuing with making a study plan.
     There are two time elements that are important to an effective study plan.The first time element to consider is the amount of time you have until the exam, while the second is the amount of time during the day that
you can set aside for studying.Try to study for at least two hours per day for major exams, like entrance
exams, and at least thirty minutes per day for lecture exams.If you are limited on the amount of time until the exam, such as one week or less, then you will need to increase your daily study time.Set up a schedule with clearly marked study times for each day.
     The content to be studied depends on the type of exam.For placement exams, entrance exams, and
licensure exams, there are no specific textbooks or prior lecture notes.There are, however, commercially
available review guides, and textbooks and lecture notes from past classes often contain a great deal of
material that will help with the exam.By looking at the content areas  of the test, you can determine what
readily available material to study.For coursebased exams, textbooks and lecture notes are both ideal study content.Break the content into chunks(块), and then assign specific chunks to the study times that you have
listed on your schedule.
     Once you have set up study times and assigned material to them, it is time to study.When reading
textbooks, take notes on the information.With lecture notes, write notes in the margin.Use a highlighter.The
idea is to make key information readily available for review.In addition, making notes and looking up ideas
to supplement notes reinforces the material in your mind.Quiz yourself as you finish each area you are
studying to determine what you still need to review.
     Study plans are as unique as the person making them.The most effective study plan will take into
account your schedule, the times each day when you are able to study without interruption, and the amount of material that needs to be reviewed.By spreading out the study times and breaking up the information,
you make it easier to absorb and retain the necessary material before the exam.

[说明]
某政府机构欲组建一个计算机网络,要求网络覆盖如图7-7所示长方形区域内的新办公楼(共16层)、旧办公楼(共7层)、礼堂(含文体中心,共3层)、培训楼(共5层)、食堂(共3层)等建筑物,并实现与Internet互联。


根据需求分析结果,该计算机网络规划要求如下。
1.信息网络中心位于新办公楼的第5层。
2.网络信息点需求情况:新办公楼平均每层需部署50个点,旧办公楼平均每层需部署30个点,培训楼平均每层需部署80个点,礼堂(含文体中心)约需部署35个点,食堂约需部署20个点。
3.为满足今后业务应用的需求,要求核心交换机至汇聚交换机以千兆链路聚合,同时千兆到桌面,食堂的一卡通刷卡机信息点允许提供百兆链路。
4.通过部署上网行为管理设备,对用户的上网行为进行安全分析、网页访问过滤、网络应用控制、带宽流量管理、信息收发审计等,以保证正常上网需求。
5.在信息网络中心的计算机机房中部署Web服务器、DNS服务器、E-mail服务器、FTP服务器等。根据业务需求,一方面要对这些服务器有较好的保护措施,另一方面要能为内网、外网用户分别提供相应的业务服务。
根据网络需求,设计师老郭设计的网络设备连接情况如图7-8所示。


[问题4]
为了提高图7-8所示网络中核心层与汇聚层之间的可用性,该网络需要新增哪种冗余网络设备并在图7-8中画出该新增的冗余设备与其他网络设备之间的链路连接关系。
