A. 按照專家能夠利用來估算
B. 按照正常的資源水平來完成任務
C. 按照不熟練資源水平完成任務
D. 使用德爾菲法
參考答案:B。專家資源不確定是否能到項目中,那就按照普通資源來估算,即正常的資源水平
44. One way to shorten your project schedule is to assign three developers to each activity in the project design phase instead of two. Although you are considering this approach, your design phase project team would double in size as a result .This approach tends to:
A. Reduce productivity
B. Increase productivity
C. Reduce the need for quality auditing, thereby reducing overall resource costs.
D. Improve production proportionately more than the increase in resources.
44. 有一種縮短項目進度的辦法是在項目設計階段的每個活動上安排3 個開發員而不是2 個,雖然你考慮這種辦法,但設計團隊將會擴大一倍。這種方法往往:
A. 降低生產率
B. 提高生產率
C. 降低了質量審計的必要,因此減少了整個的資源成本
D. 隨著資源增加,生產也按比例增加了
參考答案:A。人員增加,導致溝通渠道增加,效率變低。參見《PMBOK指南》第五版第292 頁
45.Which of the following scheduling techniques incorporates a form of risk assessment?
A. Analogous estimating
B. Program Evaluation and Review Technique (PERT)/three point estimate
C. Precedence Diagramming Method (PDM)
D. Critical Path Method (CPM)
45. 以下進度計劃制訂技巧中何種包含某種形式的風險評估?
A. 類比估算
B. 計劃評審查技術/三點估算
C. 單代號圖方法(PDM)
D. 關鍵路線法(CPM)
參考答案:B。三點估算法考慮估算中的不確定性和風險。參見《PMBOK 指南》第五版第170 頁
46.A project plan results in a project schedule that is too long. If the project network diagram cannot change but you have extra personnel resources, what should you do?
A. Fast track the project
B. Level the resources
C. Crash the project
D. Perform a value analysis
46. 一個項目規劃的結果發現項目的規劃進度要比預計要求的進度表需要更多時間,如果項目的網絡圖不能夠修改,但是你有額外的職員資源,你應該做什么?
A. 快速跟進此項目
B. 資源平衡
C. 趕工此項目
D. 進行價值分析
參考答案:C。進度落后,需要進度壓縮。快速跟進會改變活動間的邏輯關系,即改變網絡圖。趕工是通過增加資源,來壓縮活動本身的時間,不會改變邏輯關系。參見《PMBOK 指南》第五版第181 頁
47. It is crucial that your project team finish your project on time. Your team is using a technique to account for limited resources. You have also added a project buffer before the end date and feeding buffers before each critical task. What technique are you using?
A. critical path analysis
B. PERT
C. critical chain
D. earned value
47. 你的項目團隊必須按時完成項目。你的團隊使用了一種考慮有限資源的技術,在最終日期前添加了緩沖,并在關鍵活動上加入緩沖。這種技術叫做:
A. 關鍵路徑分析
B. 項目評審技術
C. 關鍵鏈
D. 掙值
參考答案:C。關鍵鏈法的定義。參見《PMBOK 指南》第五版第178 頁
48.Your project's primary constraint is quality. In order to make certain the project team members don't feel too pressed for time and to avoid schedule risk, you decide to use which of the following estimate activity durations tools?
A. Expert judgment
B. Qualitatively based durations
C. Reserve analysis
D. Analogous estimating
48. 質量是你項目的主要限制。為了不使項目小組成員對時間感到有太大的壓力,并避免進度延誤的風險,你決定采用下列哪種估算活動持續時間的工具?
A. 專家判斷
B. 基于定性的歷時
C. 儲備分析
D. 類比估算
參考答案:C。“為了不使項目小組成員對時間感到有太大的壓力,并避免進度延誤的風險”--應該多一些緩沖,即儲備。參見《PMBOK 指南》第五版第171 頁

A.一般有三種估計時間幫助預測活動歷時期望值
B.以事件為中心,在箭頭上表示活動
C.每項活動僅有一個時間估計值
D. A和B
參考答案:A。參見《PMBOK 指南》第五版第170 頁
50.Project schedule was compressed.Following are potential problem except-
A.Increased scope
B.Increased cost
C.Increased risk
D.Decreased quality
50. 壓縮項目進度,會產生下列潛在的問題,但()除外
A.范圍增加
B.成本增加
C.風險增加
D.降低質量
參考答案:A。進度壓縮的前提是不縮減項目范圍。參見《PMBOK指南》第五版第181 頁
