PK0-005 Which phase has the most total float? Practice Question

Exhibit

Refer to the exhibit.
Project Phase Schedule:
Phase A (Initiation): Duration 2 weeks, no predecessor.
Phase B (Planning): Duration 4 weeks, depends on Phase A.
Phase C (Execution): Duration 3 weeks, depends on Phase A.
Phase D (Closure): Duration 1 week, depends on Phase B and Phase C.

Which phase has the most total float?

⚠ Common exam trap

Test-takers frequently confuse total float with free float, assuming the phase with the most free float (delay without affecting successor activities) has the most total float, but total float considers the entire project end date, not just immediate successors.

Correct answer & explanation

✓

Phase C

Phase C is correct because in a typical project schedule, the phase with the most total float is the one that can be delayed the longest without affecting the project's overall completion date. Total float is calculated as the difference between the late start and early start (or late finish and early finish) of an activity. Phase C has the highest total float value, indicating it has the greatest scheduling flexibility.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Phase B
Why it's wrong here
Phase B is on the critical path and has zero float.
✗
Phase A
Why it's wrong here
Phase A is on the critical path and has zero float.
✗
Phase D
Why it's wrong here
Phase D is on the critical path and has zero float.
✓
Phase C
Why this is correct
Phase C has 1 week of float because its path is shorter than the critical path.
