Activity C is a
Answer(s): D
What is the remaining work duration of Active D?
Answer(s): C
Understand the Relationship Between G and H:The time-scaled diagram shows that Activity H starts immediately after the finish of Activity G.This is indicative of a Finish-to-Start (FS) relationship.Cross-Verification:Option A: Incorrect. The relationship is visible in the diagram.Option B: Incorrect. There is no evidence of a Start-to-Start (SS) relationship.Option D: Incorrect. Finish-to-Finish (FF) is not applicable here.Option C: Correct. FS relationship matches the network logic.
What is the relationship depicted between Activity G and Activity H?
Answer(s): B
What does the narrow band at "Y" represent?
Answer(s): A
Interpret the Narrow Band at "Y":The narrow band at "Y" is located on a part of the schedule where activities have been delayed or slowed down.Such delays typically indicate resource limitations (e.g., insufficient manpower or equipment).Reasoning:No evidence of rework or activity inactivity is explicitly shown in the diagram.Resource limitations are common in network diagrams to explain such periods.Cross-Verification:Option B: Incorrect. No evidence of rework exists.Option C: Incorrect. Activity inactivity does not fit the context.Option D: Incorrect. Sufficient information is provided.Option A: Correct. Resource limitation fits the observed diagram behavior.
What is the actual duration as of the status date or data date of Activity B?
Understand Activity B's Status:Activity B has an original duration of 5 days.As of the data date/status date, the diagram shows progress beyond 5 days.Review Actual Duration:The progress bar indicates that 7 days have already been worked on Activity B.Actual duration as of the status date = 7 days.Cross-Verification:Option B: Incorrect. Progress exceeds 3 days.Option C: Incorrect. Progress is not 0 days.Option D: Incorrect. Progress is more than 4 days.Option A: Correct. Matches the observed progress on the diagram.

Which activity is drawn in the incorrect position?
Position Analysis:Activity C (Develop Draft Plans and Specifications) has a duration of 5 months and is preceded by Activity A.The diagram positions Activity C incorrectly since it starts simultaneously with Activity B, but Activity C should start after the completion of Activity A.Cross-Verification:Based on the dependencies, Activity C’s incorrect positioning violates the logical sequencing rule.Verification with PSP Guidelines: Correct logic representation is critical for network diagrams (Ref: PSP Study Guide, Chapter 2A: Logical Sequencing).
Identify the minimum project duration.
Minimum Project Duration Calculation:The critical path determines the minimum project duration.Path: A →B →G →H →16 months.Cross-Verification with Network Diagram:Other paths have shorter durations or do not impact the overall project finish date.Verification with PSP Guidelines: Critical path analysis is central to determining project duration (Ref: PSP Study Guide, Chapter 2A: Critical Path Method).
Identify the late finish to develop plans and specs.
Late Finish Analysis for Activity C (Develop Plans and Specs):Activity C duration is 5 months, starting after Activity A (3 months).Late finish = Early start of successor (Activity E) = 10 months.Cross-Verification:Based on backward pass calculations, Activity C must end by month 10 to not delay its successor.Verification with PSP Guidelines: Late finish values are calculated during backward pass (Ref: PSP Study Guide, Chapter 2A: Backward Pass and Float Calculations).
