PMI-SP Critical Path Method 2

Question 1

A project has four paths with durations of 22, 25, 25, and 18 days. Which statement about the critical path is correct?

Accepted Answer

There are two critical paths, both 25 days long

Answer

When two or more paths share the longest duration, all of them are considered critical paths.

Question 2

In CPM, what does a 'near-critical path' signify to a project scheduler?

Accepted Answer

A path with very little float that could become critical if delayed slightly

Answer

Near-critical paths have minimal float and require monitoring because small delays can make them critical.

Question 3

Which scheduling technique extends CPM by incorporating resource constraints into the network analysis?

Accepted Answer

Critical Chain Method

Answer

Critical Chain Method (CCM) modifies the critical path to account for resource availability and dependencies.

Question 4

Activity G has an Early Start of day 10, Early Finish of day 16, Late Start of day 14, and Late Finish of day 20. What is the Total Float?

Accepted Answer

4 days

Answer

Total Float = Late Start − Early Start = 14 − 10 = 4 days (or Late Finish − Early Finish = 20 − 16 = 4 days).

Question 5

When performing a forward pass in CPM, what value is carried forward when two predecessor activities converge on a single successor?

Accepted Answer

The maximum Early Finish of the predecessors

Answer

The successor's Early Start equals the maximum Early Finish of all its predecessors, ensuring all predecessors are complete.
