MB-920 Describe Dynamics 365 Commerce Practice Question
This MB-920 practice question tests your understanding of describe dynamics 365 commerce. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
You are the Dynamics 365 Commerce administrator for a medium-sized retail company that operates 20 physical stores and an online store. The company uses Dynamics 365 Commerce with the built-in payment connector for credit card processing. Recently, the company started experiencing a high number of abandoned carts in the online store. Customers report that when they attempt to pay using a credit card, they receive an error message stating 'Payment authorization failed.' However, the same credit cards work fine when used in physical stores. The IT team has verified that the payment connector is configured correctly and that the payment gateway is operational. The online store's checkout page loads correctly and customers can enter their payment details. The error occurs only during the authorization step. What should you do to resolve this issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review and update the payment connector configuration for the online store channel.
Option B is correct because the issue is isolated to the online store channel, where the payment connector configuration may be missing or incorrect for that specific channel. Since the physical stores process payments successfully, the problem is not with the payment gateway or the connector itself, but with how the connector is configured for the online channel. Reviewing and updating the payment connector configuration for the online store channel ensures that the authorization request is properly formatted and routed.
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.
✗
Install a hardware station at the online store's data center.
Why it's wrong here
Hardware stations are used for physical stores, not online.
✓
Review and update the payment connector configuration for the online store channel.
Why this is correct
The online store channel may have incorrect payment connector settings.

Read the scenario before looking for a memorised answer.
✗
Reconfigure the credit card payment method in the headquarters.
Why it's wrong here
The payment method works in stores, so the issue is channel-specific.
✗
Contact the payment gateway provider to check for service outages.
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume a global payment method reconfiguration in HQ (Option C) will fix a channel-specific issue, or they may incorrectly think a hardware station (Option A) is needed for online payments, when in fact the online store requires a properly configured payment connector for its channel.
Detailed technical explanation
How to think about this question
In Dynamics 365 Commerce, each channel (online, retail store, call center) has its own payment connector configuration that maps to a specific payment gateway and processor. The online store uses a service-to-service integration with the payment gateway via the payment connector, which requires correct endpoint URLs, merchant IDs, and API keys. If the connector configuration for the online channel is outdated or points to a test environment, authorization will fail even though the gateway itself is operational.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
