PMI-SP Resource Leveling & Optimization 2

Question 1

What is a resource histogram used for in project scheduling?

Accepted Answer

Showing resource demand per time period to identify over- or under-allocation

Answer

Displaying the sequence of project activities over time

Answer

Tracking cumulative costs against the performance measurement baseline

Answer

Mapping team member skills to scheduled activities

Question 2

Which of the following is a valid resource optimization technique that does NOT alter the project logic network?

Accepted Answer

Reassigning work to an alternative resource with the same skill set

Answer

Adding a mandatory finish-to-start lag

Answer

Changing activity dependencies from finish-to-start to start-to-start

Answer

Eliminating a milestone to create free float

Question 3

A scheduler is told the project must finish by its contractual date and cannot be extended. Which resource optimization approach is most appropriate when a resource is over-allocated?

Accepted Answer

Resource smoothing, adjusting only within available float

Answer

Resource leveling, accepting a later finish

Answer

Compressing the schedule by adding more resources to all tasks

Answer

Removing the over-allocated resource from the project

Question 4

In a resource-constrained project, what does the term 'resource calendar' define?

Accepted Answer

The working times, non-working times, and capacity for a specific resource or resource category

Answer

The total number of resources available across all projects in a portfolio

Answer

The sequence in which resources are assigned to activities

Answer

The historical utilization log for completed projects

Question 5

What effect does resource leveling have on the schedule's total float?

Accepted Answer

Total float typically decreases or is consumed as activities are delayed

Answer

Total float increases because activities are rescheduled to optimal windows

Answer

Total float is unaffected because only resource assignments change

Answer

Total float can only increase when leveling is applied to critical activities

Question 6

Which input is MOST critical when running an automated resource leveling algorithm in scheduling software?

Accepted Answer

Accurate resource availability and maximum units defined in resource calendars

Answer

The project's risk register

Answer

The earned value performance baseline

Answer

Stakeholder communication plan

Question 7

A project manager asks why the leveled schedule shows several activities on the critical path that were not critical before leveling. What is the BEST explanation?

Accepted Answer

Leveling consumed float by delaying activities to resolve over-allocations, creating new critical paths

Answer

The scheduling software made errors in network logic

Answer

Resource leveling always creates a new critical path in the schedule

Answer

The WBS was changed during the leveling process
