37QUESTScheduling systems such as PERT, ADM, and PDM are project management tools to be used by:37AThe project manager and project office personnel.37BThe project team and functional managers.37CThe project sponsor.37DAll of the above.37EA and B only.37

38QUESTNetwork schedules are prepared during the _____ phase and updated during the _____ phase.38AConceptual, execution.38BDevelopment, implementation.38CDevelopment, close-out.38DImplementation, close-out.38EPlanning, finishing.38

QUESTDuring project execution, the customer authorizes and funds a scope change which requires a

major change in the schedule. The baseline schedule:39

39ANow becomes the new schedule, including the changes, and the original baseline is disregarded.39BIs still the original baseline but annotated to reflect that a change has taken place.

CIs amended to reflect the scope change, but the original baseline is still maintained for post-project

review.39

39DIs meaningless since every schedule update changes the baseline (i.e., a rubber baseline.)39EIs the same since baseline schedules cannot change once the development phase is completed.39

QUESTYour 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 thecorrect statement from the following:40

40AThis is a valid representation if the logic is correct.

BThis is invalid because a node can have a maximum of one dummy input representation if the

logic is correct.40

40CThis is invalid because nodes cannot have both dummy inputs and dummy outputs.40DThis is a invalid because the number of outputs must equal the number of inputs.

EThis is invalid because a maximum of two inputs and two outputs are allowed using the critical

path method.40

40

QUESTAssume 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:41

41AThe project's schedule will be reduced by 2 weeks.41BThe available slack on the noncritical paths will increase.41CA new critical path may appear after the crash.41DAll of the above.41EA and B only.41

42QUESTThe critical path in a schedule network is the path that:42ATakes the longest time to complete42BMust be done before any other tasks

QUESTIncreasing resources on the critical path activities may not always shorten the length of the project

because:ACertain activities are time-dependent rather than resource-dependent (i.e., using three ovens

rather than one to bake a cake).BSafety, OSHA and EPA may have placed restrictions on the number of people used on certain

activities or in the physical location of the project.CThe skill level of the added resources might not be appropriate for the activities to be performed.DAdding more resources may create additional work and produce inefficiencies (i.e., additional

people may need training and supervision.)EAll of the above.
