PK0-004 Question #363: Real Exam Question with Answer & Explanation

The correct answer is D: 26 days. The critical path is the longest sequence of dependent tasks that determines the project's minimum completion time. With Task B extended to 10 days (an increase from its original duration), the path containing Task B becomes longer. Based on the referenced table (not visible here

Question

Based on the table below: Which of the following is the critical path if Task B has extended to ten days?

Exhibit

Options

A21 days
B23 days
C24 days
D26 days

Explanation

The critical path is the longest sequence of dependent tasks that determines the project's minimum completion time. With Task B extended to 10 days (an increase from its original duration), the path containing Task B becomes longer. Based on the referenced table (not visible here), the path containing Task B with the 10-day extension sums to 26 days - making it the longest path and therefore the critical path. The other answer options (21, 23, 24 days) represent either non-critical paths or the original durations before Task B's extension. When any task on the critical path is extended, the overall project duration increases by the same amount, and 26 days reflects that recalculation.
