The critical path in a network is the path that:

A.Has the greatest degree of risk.

B.Will elongate the project if the activities on this path take longer than anticipated.

C.Must be completed before all other paths.

D.All of the above.

E.A and B only.

During a project review meeting, you discover that your $250,000 project has a negative schedule variance of $20,000 which equates to 12% of the work scheduled to this point of time. You can therefore conclude that:

A . The project will be completed late.

B . The critical path has been lengthened.

C . the costs are being overrun.

D . Overtime will be required to maintain the original critical path.

E . None of the above.

The schedule risk is the _____ .

A the accumulated "expected' durations which maintain project completion.

B Critical Path adjusted by "high-risk" activity float.

C highest risk path that maintains quality.

D Critical Path when calculated with "most likely" duration.

E highest risk path that contributes the most risk toward the project completion.

88 A non-critical path activity is completed in half the time. Then,

A. The critical path is also reduced.

B. The slack in the path containing this activity will increase.

C. The total cost for this activity has decreased.

D. Manpower from this activity can be assigned to other activities.

E. All of the above
