PK0-005 Practice Question: Refer to the exhibit

Exhibit

Refer to the exhibit.

```
[Project Schedule - Critical Path]
Task A (5d) -> Task C (3d) -> Task E (4d) -> Task G (2d)
Task B (6d) -> Task D (4d) -> Task F (5d) -> Task H (3d)
Dependencies: Task C depends on A and B; Task D depends on B; Task E depends on C; Task F depends on D; Task G depends on E; Task H depends on F. All durations in days. No other dependencies.
```

Refer to the exhibit. What is the total float for Task D?

⚠ Common exam trap

CompTIA often tests the concept that tasks on the critical path have zero total float, and the trap here is that candidates may miscalculate float by using incorrect early/late dates from the diagram or confuse total float with free float, leading to picking a non-zero value.

Correct answer & explanation

✓

0 days

Task D has a total float of 0 days because it lies on the critical path. In the network diagram, its early start (ES) equals its late start (LS), and its early finish (EF) equals its late finish (LF), indicating no schedule flexibility. This means any delay in Task D would directly extend the project duration. The critical path includes Task D, so total float is zero.
