Answer

Free float

Answer

Independent float

Answer

Interfering float

Question 6

Accepted Answer

Activity compression

Answer

Activity segmentation

Answer

Resource smoothing

Answer

Risk analysis

Question 7

What is the primary purpose of calculating project slack in CPM?

Accepted Answer

To determine the amount of flexibility in a task's schedule while ensuring the project is completed on time

Answer

To identify critical activities

Answer

To estimate the project completion time

Answer

To evaluate the project's risk level

Question 8

Which of the following is NOT taken into account in CPM calculations?

Accepted Answer

Project budget

Answer

Task duration

Answer

Task dependencies

Answer

Resource availability

Question 9

Which element is NOT included in the Critical Path Method (CPM)?

Accepted Answer

Project start and finish dates

Answer

Activities and their durations

Answer

Dependencies between activities

Answer

Slack time of activities

Question 10

What does a negative slack time indicate for an activity?

Accepted Answer

The activity is critical and any delay will impact the project duration.

Answer

The activity has some flexibility in its schedule.

Answer

The activity is not on the critical path and can be delayed without affecting the project.

Answer

The activity is behind schedule and needs to be expedited.

Question 11

Which of the following techniques is used to determine the critical path in a project?

Accepted Answer

Forward and backward pass

Answer

PERT analysis

Answer

Gantt chart

Answer

Milestone chart

Question 12

What is the primary benefit of using CPM in project planning?

Accepted Answer

It helps identify the minimum project duration and critical activities.

Answer

It allows for accurate resource allocation and leveling.

Answer

It eliminates uncertainties from the project.

Answer

It guarantees project success and profitability.

Question 13

How are predecessor and successor activities related in CPM?

Accepted Answer

Predecessor activities occur before successor activities.

Answer

Successor activities occur before predecessor activities.

Answer

Predecessor activities have negative slack time while successor activities have positive slack time.

Answer

Predecessor activities are not related to successor activities.

Question 14

What is the definition of the critical path in a project network?

Accepted Answer

The path with the least amount of slack time.

Answer

The longest path from the project start to finish.

Answer

The shortest path from the project start to finish.

Answer

The path with the most activities.

Question 15

How can CPM be effectively utilized in agile project management, given its iterative nature?

Accepted Answer

CPM can be used in agile projects by breaking the project into smaller iterations and updating the CPM diagram as the project progresses.

Answer

CPM is ineffective in agile projects due to their dynamic nature.

Answer

CPM is only applicable in the initial planning phase of agile projects.

Answer

Agile projects require a detailed project plan using CPM at the project's start.

Question 16

In CPM, the **critical path** refers to:

Accepted Answer

The sequence of tasks that determines the **overall project duration**.

Answer

The sequence of tasks with the most **slack**.

Answer

The sequence of tasks with the **least** slack.

Answer

The sequence of tasks with the **highest** resource requirements.

Question 17

The difference between the **early start** and **early finish** dates of a task represents:

Accepted Answer

The amount of **slack** available for the task.

Answer

The duration of the task.

Answer

The latest possible start and finish dates of the task.

Answer

The difference between the planned and actual start/finish dates.

Question 18

Which of the following is **NOT** a benefit of using CPM in project management?

Accepted Answer

Elimination of uncertainty in project timeline.

Answer

Improved project planning and scheduling.

Answer

Reduced project duration.

Answer

Increased project flexibility.

Question 19

The purpose of **float** in CPM is to:

Accepted Answer

Provide **flexibility** in scheduling tasks.

Answer

Identify critical tasks.

Answer

Calculate the project duration.

Answer

Minimize resource usage.

Question 20

Which of the following is NOT a type of float in CPM?

Accepted Answer

Resource float.

Answer

Total float.

Answer

Free float.

Answer

Schedule float.

Question 21

Reducing the duration of a task on the **critical path** will:

Accepted Answer

Reduce the overall project duration.

Answer

Increase the overall project duration.

Answer

Have no impact on the overall project duration.

Answer

Depend on the amount of reduction.

Question 22

The difference between the **forward pass** and **backward pass** in CPM is:

Accepted Answer

Forward pass calculates **early** dates, while backward pass calculates **late** dates.

Answer

Forward pass calculates **late** dates, while backward pass calculates **early** dates.

Answer

Forward pass determines the critical path, while backward pass calculates float.

Answer

There is no difference between forward and backward pass.

Question 23

The role of a **Gantt chart** in conjunction with CPM is to:
