MB-920 Practice Question: Describe the core capabilities of the finance and operations apps
This MB-920 practice question tests your understanding of describe the core capabilities of the finance and operations apps. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. A company configures Dynamics 365 Supply Chain Management with the parameters shown. They notice that material requirements planning (MRP) is recalculating every time a sales order is entered, causing performance issues. Which parameter should be changed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ExplosionMode
The 'ExplosionMode' parameter controls when MRP recalculates demand. Setting it to 'Always' causes MRP to regenerate every time a sales order is entered, leading to performance degradation. Changing it to 'Never' or 'MinMax' prevents unnecessary recalculations and improves system responsiveness.
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.
✓
ExplosionMode
Why this is correct
Setting explosionMode to 'Always' triggers MRP recalculation on every change; setting it to 'Never' or 'On change' improves performance.

✗
DynamicPlan
Why it's wrong here
DynamicPlan being 'Yes' is standard for real-time planning.
✗
RouteNetwork
Why it's wrong here
RouteNetwork defines the route sequence, not MRP recalculation frequency.
✗
FrozenPlan
Why it's wrong here
FrozenPlan is used to freeze a plan, not the root cause.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'ExplosionMode' with 'DynamicPlan' or 'FrozenPlan', assuming those parameters control the frequency of MRP recalculation, when in fact they control planning horizons and time fences respectively.
Detailed technical explanation
How to think about this question
In Dynamics 365 Supply Chain Management, the ExplosionMode parameter is part of the coverage group settings. When set to 'Always', MRP performs a full explosion for every demand change, which can be resource-intensive. In real-world scenarios, companies with high sales order volumes often set this to 'Never' and rely on scheduled batch MRP runs to avoid performance hits, while using 'MinMax' for critical items that need immediate replenishment signals.
KKey Concepts to Remember

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
