This MB-920 practice question tests your understanding of describe dynamics 365 commerce. 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.
Which THREE of the following are components of the Dynamics 365 Commerce architecture?
Retail Server
Core component providing services.
Commerce Data Exchange
Synchronizes data between HQ and channels.
Azure Data Lake
Why wrong: Used for analytics, not core architecture.
Power BI
Why wrong: Power BI is a reporting tool, not part of Commerce architecture.
Channel database
Stores data for offline and online channels.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Retail Server
Retail Server is a core component of Dynamics 365 Commerce architecture that acts as the middleware between the channel database and client devices (such as POS terminals and e-commerce front ends). It exposes OData RESTful endpoints to handle business logic, transactions, and data retrieval, ensuring offline-capable and real-time operations across channels.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates confuse external Azure services or reporting tools (like Azure Data Lake or Power BI) with the core architectural components that are specifically part of the Commerce channel infrastructure, leading them to select options that are integrations rather than built-in components.
Detailed technical explanation
The Dynamics 365 Commerce architecture is built on a distributed, channel-based model where Retail Server handles CRUD operations via OData v4, and Commerce Data Exchange (CDX) synchronizes data between the back office (Headquarters) and channel databases using batch jobs and real-time service calls. The channel database stores transactional and master data locally at each channel, enabling offline resilience and high performance during peak loads.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
