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.
A Dynamics 365 Commerce administrator reviews the Retail Server configuration exhibit. Customers report that the checkout page does not appear. Based on the exhibit, what is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Checkout page is not configured.
The Retail Server configuration in Dynamics 365 Commerce includes a dedicated 'Checkout page' setting that must be explicitly linked to a valid page URL. If this field is empty or points to a non-existent or unpublished page, the checkout page will not render, causing the reported issue. The exhibit likely shows this field is blank or misconfigured, making 'Checkout page is not configured' the most direct cause.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse functional settings (like guest checkout or default customer) with the page-level configuration required for the checkout page to render, overlooking the direct link between the Retail Server's page mapping and the actual page availability.
Detailed technical explanation
How to think about this question
Under the hood, the Retail Server uses a channel configuration entity (RetailChannelTable) where the 'CheckoutPageId' field maps to a Commerce site builder page record. If this field is null or references a deleted page, the Commerce runtime fails to resolve the checkout URL during the cart-to-checkout flow, resulting in a blank or error page. In real-world scenarios, this often occurs after a site migration or when a page is unpublished without updating the channel configuration.
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 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.
