MB-920 Describe Dynamics 365 Project Operations Practice Question
This MB-920 practice question tests your understanding of describe dynamics 365 project operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A consulting firm uses Dynamics 365 Project Operations to manage fixed-price projects. During project execution, the project manager notices that the actual cost is exceeding the budget. What should the project manager do to track and communicate the impact on profit?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the Cost Performance Index (CPI) on the project and update the estimate at completion (EAC).
In Dynamics 365 Project Operations, the Cost Performance Index (CPI) is the key metric for measuring cost efficiency on a project. When actual costs exceed the budget, the project manager should review the CPI and update the Estimate at Completion (EAC) to forecast the total expected cost based on current performance, directly communicating the impact on profit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Analyze resource utilization percentages to identify over-allocated resources.
Why it's wrong here
Resource utilization does not directly measure profit impact.
✓
Review the Cost Performance Index (CPI) on the project and update the estimate at completion (EAC).
Why this is correct
CPI is the correct metric to monitor cost efficiency and forecast final costs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Review the Schedule Performance Index (SPI) to assess if the project is behind schedule.
Why it's wrong here
SPI measures schedule, not cost performance.
✗
Compare the project budget to the actual cost in the project invoice.
Why it's wrong here
Invoices reflect billed amounts, not ongoing cost efficiency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse cost performance metrics (CPI) with schedule metrics (SPI) or operational metrics (resource utilization), leading them to select options that address resource allocation or schedule delays instead of the direct cost-to-profit impact.
Detailed technical explanation
How to think about this question
In Dynamics 365 Project Operations, the CPI is calculated as Earned Value (EV) divided by Actual Cost (AC), and updating the EAC uses the formula EAC = Budget at Completion (BAC) / CPI, which provides a revised total cost forecast. This is part of the Earned Value Management (EVM) engine within the application, which automatically computes these values from time, expense, and material transactions. A real-world scenario is a fixed-price project where a CPI below 1.0 triggers an automatic reforecast, allowing the project manager to communicate revised profit margins to stakeholders.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
