A 21
B 22
C 23
D 24
E 25
ans:D
2 Using the data shown in the Special window, Activities P, Q, and T are critical path activities. In order to shorten the time duration of the project, which activity should be "crashed" first?
A P
B Q
C R
D S
E T
ans:A
3 Using the figure in the Special window, By how many weeks can activity "F" slip without extending the end date of the project?
A 0
B 1
C 2
D 3
E 4
ans:D
4 Using the figure in the Special window, The critical path is:
A A-B-G
B C-G
C C-D
D E-F
E A-B-G and C-D
ans:B
5 The first step in building a PERT/CPM network is to:
A Create a flow chart
B Determine the critical path
C Show task relationships
D Create a work breakdown structure
E None of the above.
ans:D
6 The critical path in a schedule network is the path that:
A Takes the longest time to complete
B Must be done before any other tasks
C Allows some flexibility in scheduling a start time.
D Is not affected by schedule slippage
E All of the above.
ans:A
7 Assume that you have a network where an activity on the critical path can be crashed by two weeks. If the activity is actually crashed by two weeks, then:
A The project's schedule will be reduced by 2 weeks.
B The available slack on the noncritical paths will increase.
C A new critical path may appear after the crash.
D All of the above.
E A and B only.
ans:C
8 Your team has prepared a CPM schedule for your review. You notice that one node has six inputs (including two dummy activities) and four outputs (which include one dummy activity). Select the correct statement from the following:
A This is a valid representation if the logic is correct.
B This is invalid because a node can have a maximum of one dummy input representation if the logic is correct.
C This is invalid because nodes cannot have both dummy inputs and dummy outputs.
D This is a invalid because the number of outputs must equal the number of inputs.
E This is invalid because a maximum of two inputs and two outputs are allowed using the critical path method.
ans:A
9 During project execution, the customer authorizes and funds a scope change which requires a major change in the schedule. The baseline schedule:
A Now becomes the new schedule, including the changes, and the original baseline is disregarded.
B Is still the original baseline but annotated to reflect that a change has taken place.
C Is amended to reflect the scope change, but the original baseline is still maintained for post-project review.
D Is meaningless since every schedule update changes the baseline (i.e., a rubber baseline.)
E Is the same since baseline schedules cannot change once the development phase is completed.
ans:C
10 Network schedules are prepared during the _____ phase and updated during the _____ phase.
A Conceptual, execution.
B Development, implementation.
C Development, close-out.
D Implementation, close-out.
E Planning, finishing.
ans:B
11 Scheduling systems such as PERT, ADM, and PDM are project management tools to be used by:
A The project manager and project office personnel.
B The project team and functional managers.
C The project sponsor.
D All of the above.
E A and B only.
ans:E
12 Increasing resources on the critical path activities may not always shorten the length of the project because:
A Certain activities are time-dependent rather than resource-dependent (i.e., using three ovens rather than one to bake a cake).
B Safety, OSHA and EPA may have placed restrictions on the number of people used on certain activities or in the physical location of the project.
C The skill level of the added resources might not be appropriate for the activities to be performed.
D Adding more resources may create additional work and produce inefficiencies (i.e., additional people may need training and supervision.)
E All of the above.
ans:E
