Question 1

All of the following strategies can help a project team to develop realistic time estimates for project activities EXCEPT:
A) adding a significant buffer to each activity
B) be sure to consider learning curves,interruptions and competing priorities
C) estimate times of completion without initial reference to a calendar
D) verify the time estimates with the people doing the work

Accepted Answer

Adding a significant buffer to each activity may lead to overly conservative estimates and does not necessarily help in developing realistic time estimates. It is important to consider factors such as learning curves, interruptions, and competing priorities, estimate times of completion without initial reference to a calendar and verify the time estimates with the people doing the work to develop realistic time estimates.

Question 2

Which of the following responses identifies a common type of logical dependency used to sequence project activities?
A) first-in; first-out
B) last-in; last-out
C) finish-to-start
D) last-in; first-out

Accepted Answer

Finish-to-start is the most common type of logical dependency used to sequence project activities, where the finish of one activity is dependent on the start of another activity.

Question 3

Creating a realistic schedule is often an iterative process because several factors can limit how fast a project can be completed.All of the following factors can limit how fast a project can be scheduled and completed EXCEPT:
A) logical order
B) imposed dates
C) resource availability
D) quality metrics

Accepted Answer

Quality metrics may be a factor in ensuring that a project is completed to a certain standard, but they do not directly limit how fast a project can be scheduled and completed. Logical order, imposed dates, and resource availability can all impact the timeline of a project.

Question 4

The sequencing of activities is often based upon dependencies between the activities.The dependencies that should guide activity sequencing can be either:
A) critical or non-critical
B) opportunities or threats
C) mandatory or discretionary
D) interior or exterior

Accepted Answer

The dependencies that should guide activity sequencing are divided into two categories—mandatory and discretionary. Mandatory dependencies are those that are inherent in the nature of the work being performed, while discretionary dependencies are those that are established by the project team.

Question 5

All of the following problems contribute to difficulty in estimating activity durations accurately EXCEPT:
A) merging - multiple predecessors
B) omissions - leaving out key activities
C) general uncertainty in the estimate
D) poor vendor selection

Accepted Answer

Poor vendor selection does not contribute to difficulty in estimating activity durations accurately. The other options (merging, omissions, and general uncertainty) can make it challenging to determine how long a particular activity will take to complete.

Accepted Answer

The answer of Which of the following statements correctly describes...

Question 10

An activity that logically comes before a dependent activity in a schedule is called a ___:
A) leader activity
B) predecessor activity
C) successor activity
D) mandatory activity

Accepted Answer

A predecessor activity is an activity that must be completed before another dependent activity can begin. Therefore, it logically comes before the dependent activity in the schedule. The other options (leader activity, successor activity, mandatory activity) do not capture this relationship.

Question 11

The total number of work periods (not including holidays or other non-work periods)required to complete a schedule activity is known as:
A) effort
B) elapsed time
C) duration
D) resource days

Accepted Answer

The definition of duration specifies that it refers to the total number of work periods required to complete a schedule activity. It does not take into account any non-work periods or holidays. Therefore, option C is the best choice. Option A (effort) refers to the amount of work required to complete an activity in terms of labor, while option B (elapsed time) refers to the actual amount of time from the start of an activity to its completion, including non-working periods such as holidays. Option D (resource days) refers to the amount of effort or labor that a particular resource has available to work on an activity.

Question 12

All of the following items can provide useful assistance to a project team to define the activities of a project EXCEPT:
A) the work packages from the Work Breakdown Structure
B) issue logs
C) checklists for projects of the same type
D) schedules from similar projects that are already completed

Accepted Answer

Issue logs do not provide information on the specific activities needed to complete a project. Work packages, checklists, and schedules from similar projects can all provide valuable information for defining project activities.

Question 13

Estimating the number of work periods that will be needed to complete individual schedule activities characterizes which of the following time management processes?
A) Define activities
B) Sequence activities
C) Estimate activity duration
D) Create WBS

Accepted Answer

Estimating the number of work periods needed to complete individual schedule activities is part of the Estimate Activity Duration process. This process involves estimating the amount of time required to complete each individual activity based on the resources that will be available and the level of effort required.

Question 14

Figure 7-2 Research Project
-Consider the Research Project depicted in Figure 7-2.Based on the information provided,what is the late start date for activity C - "Review Reports"?
A) Day 0
B) Day 2
C) Day 4
D) Day 10

Accepted Answer

The late start date for activity C - "Review Reports" is the latest possible day that the activity can start without delaying the project. Based on the information provided in Figure 7-2, the latest possible day that activity C can start is day 4, which is calculated by subtracting the activity duration of 2 days from the late finish date of activity D, which is day 6. Therefore, the answer is C) Day 4.

Question 15

Figure 7-2 Research Project
-Consider the Research Project depicted in Figure 7-2.Based on the information provided,what is the late start date for activity A - "Plan Research"?
A) Day 0
B) Day 2
C) Day 4
D) Day 10

Accepted Answer

The late start date for activity A - "Plan Research" is Day 0 because it is the first activity in the project and typically starts at the beginning of the project timeline.

Question 16

Milestones are important points in a project schedule that can serve as check points for project managers and sponsors.All of the following reasons might justify the decision to establish a milestone EXCEPT:
A) completion of a major deliverable
B) the time right before a large amount of money needs to be committed
C) a merging point where multiple activities must be completed before progress can continue
D) scheduling team status meetings

Accepted Answer

Scheduling team status meetings is not a milestone as it is a regular activity in project management and does not represent a significant point in the project schedule. The other options represent important points in the project timeline where progress and success can be measured, making them potential milestones.

Question 17

Which of the following remedies may reduce the likelihood of omissions when developing activity duration estimates?
A) lessons learned
B) resource buffers
C) learning curve
D) staggering project start dates

Accepted Answer

The answer of Which of the following remedies may reduce...

Question 19

Faced with significant schedule challenges,the project manager has several responsibilities.All of the following are among the project manager's responsibilities EXCEPT:
A) willingly accept end dates dictated by customers or sponsors
B) persuade all stakeholders that the schedule makes sense
C) deliver the project according to the agreed-upon schedule
D) determine a schedule that is possible to achieve

Accepted Answer

The project manager should not simply accept end dates dictated by customers or sponsors without first evaluating whether they are realistic and achievable. It is the project manager's responsibility to determine a schedule that is possible to achieve, persuade stakeholders that the schedule makes sense, and ultimately deliver the project according to the agreed-upon schedule.

Question 20

The amount of time a schedule activity can be delayed without delaying the early start date of any successor is known as:
A) reserve
B) free float
C) contingency
D) lead

Accepted Answer

Free float is the amount of time that a scheduled activity can be delayed without delaying the early start date of any successor activity. It helps to identify the amount of flexibility available in a schedule and allows the project team to prioritize activities based on their level of criticality. Reserve is a time buffer added to the overall duration of a project to account for uncertainty and risks. Contingency refers to a predetermined action plan or response to an identified risk event. Lead refers to the amount of time by which a successor activity can be advanced with respect to its predecessor activity.
