PMP认证考试练习题（29,30）

The range of time allowed for an activity to be completed in is the （    ）.

Free float is the amount of time that an activity may be delayed with out affecting the （    ）.

Using the problem stated in the Special window, Calculate the deviation of duration for the task, using the PERT concept of standard deviation of task duration.

In crashing a task, you would focus on:

Using the problem stated in the Special window, Calculate the expected value of duration (in days) using the PERT concept of the expected duration of a task

Using the WBS in the Special window, an instance of a work package is:

All of the following are categories of a milestone in a schedule except:

The actual configuration of a PERT/CPM network （    ） the amount of resources that can be devoted to the project.

Excessive flexibility in specifying requirements will （    ） the likelihood of time overruns.

The key purpose of project control is to:

Fast tracking means to:

As a project is carried out and slack time is consumed on individual tasks, the slack left over for the remaining tasks is:

The purpose of a dummy activity in an activity-on-arrow diagram is to:

On November 1, $1000 worth of work on task A was supposed to have been done (BCWS); however, the BCWP was $850. Calculate the schedule variance:

A plan has budgeted three weeks of effort for consultants, but the job was done in only two weeks. Calculate the variance:

Resource leveling will often affect the project by making it:

Using the figure in the Special window, The slacktime in Activity "G" is （    ） weeks.

Using the figure in the Special window, Activity "D" has a latest start time of （    ） weeks and a latest finish time of （    ） weeks.

Using the figure in the Special window, Activity "L" has an early start time of （    ） weeks and an early finish time of （    ） weeks.

Using the figure in the Special window, The Critical path is （    ） weeks.

Using the data shown in the Special window, Activities P, Q, and T are critical path activities. In order to shorten the time duration of the project, which activity should be "crashed" first?

Using the figure in the Special window, By how many weeks can activity "F" slip without extending the end date of the project?

Using the figure in the Special window, The critical path is:

The first step in building a PERT/CPM network is to:

The critical path in a schedule network is the path that:

Assume that you have a network where an activity on the critical path can be crashed by two weeks. If the activity is actually crashed by two weeks, then:

Your team has prepared a CPM schedule for your review. You notice that one node has six inputs (including two dummy activities) and four outputs (which include one dummy activity). Select the correct statement from the following:

During project execution, the customer authorizes and funds a scope change which requires a major change in the schedule. The baseline schedule:

Network schedules are prepared during the （    ） phase and updated during the （    ） phase.

Scheduling systems such as PERT, ADM, and PDM are project management tools to be used by:

Increasing resources on the critical path activities may not always shorten the length of the project because:

A line manager provides you with three estimates for his activity in your PERT network. His estimates are 2 weeks optimistically, 4 weeks most likely, and 12 weeks pessimistically. The expected time which would appear on the chart would be:

Management has decided to "crash" a project in order to avoid penalty payments for late deliveries. To crash the project, either overtime or additional resources should be assigned to:

A network has been developed with resources from six different departments. One of the six departments has just informed you that they can increase the number of employees from 5 to 8. This will result in:

Bar charts are most appropriate for:

A non-critical path activity is completed in half the time. Then,

Once the logic of a network is laid out, the project manager will conduct a forward pass and backward pass through the network. This will provide information on the （    ） and identification of the （    ） .

ADM is an activity-on-arrow method. In this method, a dummy activity:

The starting point in the development of a top-down PERT/CPM chart is the （    ） .
