1．Increasing resources on the critical path activities may not always shorten the length of the project because:
A．No activities are time-dependent or resource-dependent
B．Activities are always scheduled with optimal number of resources
C．The Project Manager always selects original resources with the highest skill levels
D．Adding more resources may create additional work and produce inefficiencies
在關鍵路線上增加資源不會總是縮短項目的時間長度,這是因為:
A．沒有活動是依賴時間或依賴資源的
B．總是以最佳的資源數(shù)量來安排活動
C．項目經(jīng)理總選擇具有最高技能水平的初始資源
D．增加更多的資源可能產(chǎn)生額外的工作并且導致效率低

2．Among the common types of scheduling techniques, task relationships are best illustrated using:
A．Networks
B．Gantt charts
C．Milestone charts
D．Work Breakdown structure
在計劃安排技術的普通類型中用下列哪一項能最好地說明工作任務關系:
A．網(wǎng)絡
B．甘特Gantt圖
C．里程碑圖
D．工作分解結(jié)構

3．Bar charts are most appropriate for:
A．Comparing actual to planned performance for each activity
B．Showing slack time
C．Showing critical path dependencies
D．Showing which activities can be rearranged in parallel
柱形圖最適合于:
A．對每項活動比較實際的與計劃的績效
B．表示松弛時間
C．表示關鍵路線的依賴關系
D．表示哪些活動能被重新并行安排

4．Using the figure below, activity D has a latest start time of weeks and a
latest finish time of weeks．
A．2, 10
B．4, 12
C．6, 14
D．7, 15
利用下圖數(shù)字計算, 活動 D 最遲開始時間是周和最遲完成時間是周
A．2,10
B．4,12
C．6,14
D．7,15

5．Which of the following does not represent the critical path?
A．Has a high degree of risk
B．Will elongate the project if the activities on this path take longer than anticipated
C．Must remain on schedule
D．Has the largest number of activities of any path
下列哪一項不代表關鍵路線?
A．有高度風險
B．如果這條路線上的活動要比所預期的花更長時間,項目時間將延長
C．必須保持按進度

D．任何有最大數(shù)目活動的路線
6．Networks are a result of the process and a key input to the process．
A．Activity definition, duration estimating
B．Activity sequencing, schedule development
C．Activity planning, schedule development
D．Activity sequencing, duration estimating
任務網(wǎng)絡是過程的一個結(jié)果和是對過程的一項關鍵的輸入
A．活動定義, 工期估計
B．活動排序,進度制定
C．活動規(guī)劃,進度制定
D．活動排序, 工期估計

7．Which method shown below would normally not be used for shortening the schedule?
A．Crashing
B．Changing the scope
C．Performing activities in parallel rather than in series
D．Resource leveling
下面哪一方法通常不會被用來縮短進度?
A．趕工
B．變更范圍
C．以并行方式而不是序列方式來實施進行活動
D．資源平衡

8．In a start-to-start relationship between two tasks not on the critical path, the project team determines that the start of the successor task must be delayed 3 days after the start of its predecessor．This delay is referred to as
A．Slack
B．Free float
C．Level float
D．Lag
在非關鍵路線上的二件工作之間的開始到開始關系中項目團隊認為: 在前序工作開始之后, 后序工作的開始時間要被延遲3天這種延遲被稱為
A．時差
B．自由時差
C．水平時差
D．滯后

9．In some Arrow Diagramming Method (ADM) networks, the project manager may be required to indicate logic relationships that do not consumer resources or time．These relationships are shown by using:
A．Critical path activities
B．Non-critical path activities
C．Slack time activities
D．Dummy activities
在箭線圖示法(ADM) 網(wǎng)絡中可能要求項目經(jīng)理標明不消耗資源或時間的邏輯關系表
示這種關系可借助于:
A．關鍵路線活動
B．非關鍵路線活動
C．有閑時間活動
D．虛活動

10．A possible disadvantage of a bar chart is that it:
A．Lacks time-phasing
B．Cannot display more than one variable
C．Does not show activity interrelationships well on large complex projects
D．Cannot be related to manpower planning
柱形圖的一個可能的缺點(劣勢)是:
A．缺乏時間定位
B．不能展示出多個變量
C．在大的復雜項目上,不能很好地表示出活動之間的相互關系
D．不能與人力規(guī)劃相聯(lián)系
