MB-920 Describe Dynamics 365 Commerce — 15 Questions

Question 1

A retail company uses Dynamics 365 Commerce for its online and physical stores. Customers are reporting that items added to their online shopping cart are not being reserved in the physical store's inventory. The company uses the 'Reserve inventory' feature. What is the most likely cause of this issue?

Accepted Answer

The 'Process inventory reservation' batch job is not scheduled or is failing.. The 'Reserve inventory' feature in Dynamics 365 Commerce relies on the 'Process inventory reservation' batch job to synchronize online cart reservations with physical store inventory. If this batch job is not scheduled or is failing, items added to the online shopping cart will not be reserved in the store's inventory, causing the reported issue. This is the most likely cause because the batch job is responsible for processing reservation requests from the online channel.

Answer

The 'Pick inventory' job is not configured.

Answer

The 'Reserve inventory' feature is disabled for the online store channel.

Answer

Inventory is not set up at the store level.

Question 2

A company is setting up a new store in Dynamics 365 Commerce. They want to ensure that prices for products are automatically updated across all channels when changed in the head office. Which configuration should they use?

Accepted Answer

Set up a Commerce Data Exchange (CDE) schedule for price updates.. Commerce Data Exchange (CDE) is the dedicated Dynamics 365 Commerce component for synchronizing data between the head office (HQ) and channel databases. A CDE schedule specifically handles the distribution of master data changes, such as price updates, ensuring that all channels (e.g., online stores, POS terminals) receive the updated prices automatically and consistently. This is the correct configuration for automated, scheduled price propagation across channels.

Answer

Use the Point of Sale (POS) to update prices directly.

Answer

Configure Retail Server to push price changes.

Answer

Enable real-time service for the channel database.

Question 3

A company uses Dynamics 365 Commerce and has multiple stores. They want to implement a loyalty program where customers earn points based on purchase amounts, and the points can be redeemed at any store. The program should also allow for tiered rewards. Which component should be used to define the loyalty program rules?

Accepted Answer

Loyalty module in Dynamics 365 headquarters. The Loyalty module in Dynamics 365 headquarters is the correct component because it is the centralized back-office tool where loyalty program rules—such as earning rates, redemption rules, and tier definitions—are configured. This module allows you to define program-wide settings that apply across all stores, ensuring consistent point accrual and redemption behavior regardless of where the customer shops.

Answer

Channel database

Answer

Point of Sale (POS)

Answer

Retail Server

Question 4

A retail company is planning to expand its online presence and wants to use Dynamics 365 Commerce to build a new e-commerce site. They need to ensure that the site can handle high traffic during promotional events and that product catalog updates are reflected quickly. What should they consider?

Accepted Answer

Use a content delivery network (CDN) and optimize catalog synchronization.. Option C is correct because using a Content Delivery Network (CDN) caches static assets (images, scripts, CSS) at edge nodes, reducing load on the origin server during high-traffic promotional events. Optimizing catalog synchronization (e.g., using incremental syncs and the Commerce Data Exchange) ensures product updates are reflected quickly without full re-indexing, maintaining performance and data freshness.

Answer

Increase the size of the channel database.

Answer

Disable caching for product pages to ensure fresh data.

Answer

Limit the number of products in the catalog.

Question 5

A store manager needs to process a return for a customer who purchased an item using a loyalty card. The manager wants to ensure that the loyalty points originally earned from that purchase are reversed. What should the manager do?

Accepted Answer

Process the return using the standard return function in POS.. In Dynamics 365 Commerce, the standard return function in POS automatically reverses any loyalty points that were earned on the original transaction. This ensures that the customer's loyalty balance is accurately adjusted without manual intervention or external requests.

Answer

Issue a store credit instead of a refund to keep the points.

Answer

Contact the head office to adjust the points.

Answer

Manually deduct the loyalty points from the customer's account.

Question 6

A company uses Dynamics 365 Commerce and has set up a new online store. They notice that the product images are not displaying on the product detail pages. The images are stored in the media library in the headquarters. What is the most likely cause?

Accepted Answer

The images have not been published to the online store channel.. In Dynamics 365 Commerce, product images must be explicitly published to the online store channel after being uploaded to the headquarters media library. Simply storing images in the media library does not make them available on the product detail pages; they require a channel-level publication step to synchronize and render on the storefront. This ensures that only approved media is visible to customers.

Answer

The images lack alternative text.

Answer

Commerce Data Exchange is not configured for image synchronization.

Answer

The images are not uploaded to the media library.

Question 7

A retail chain is implementing Dynamics 365 Commerce and wants to enforce that all stores use the same pricing structure. However, one store manager needs to offer a local discount to match a competitor. What is the best way to handle this?

Accepted Answer

Create a price adjustment for that specific store.. A price adjustment in Dynamics 365 Commerce allows you to apply a discount to a specific product for a specific store or channel without altering the global base price. This meets the requirement of maintaining a consistent pricing structure across all stores while enabling the local store manager to offer a targeted discount to match a competitor. Price adjustments are the standard mechanism for temporary or localized pricing changes in Commerce.

Answer

Have the store manager manually override the price at POS.

Answer

Change the base price for the product globally.

Answer

Create a new product assortment for that store.

Question 8

A company uses Dynamics 365 Commerce and wants to track inventory across multiple warehouses. They need to ensure that inventory levels are updated in real-time when a sale is made at the store. Which feature should they use?

Accepted Answer

Enable Real-time Service in the POS.. Option B is correct because Real-time Service in the POS enables immediate inventory updates by sending transactions directly to the Dynamics 365 Commerce headquarters as they occur. This ensures that inventory levels across multiple warehouses are synchronized in real-time when a sale is made at the store, meeting the requirement for up-to-the-minute accuracy.

Answer

Configure the channel database to update inventory directly.

Answer

Use Commerce Data Exchange to sync inventory.

Answer

Schedule a batch job to update inventory every hour.

Question 9

Which TWO of the following are valid methods to handle product returns in Dynamics 365 Commerce?

Accepted Answer

Process a return through the online store's customer portal.. Option B is correct because Dynamics 365 Commerce allows customers to initiate returns through the online store's customer portal, which integrates with the return order process in the system. This self-service capability enables customers to select items from their order history and submit a return request without needing to contact a call center or visit a physical store.

Answer

Allow customers to return items via the call center without an order reference.

Answer

Use the vendor returns functionality for customer returns.

Answer

Use the Inventory management module to create a return order.

Question 10

Which THREE of the following are components of the Dynamics 365 Commerce architecture?

Accepted Answer

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.

Answer

Azure Data Lake

Answer

Power BI

Question 11

Which TWO of the following are valid reasons to use the 'Offline mode' in Dynamics 365 Commerce POS?

Accepted Answer

To continue processing sales when the internet connection is lost.. Options B and D are correct. B is correct because if the network connection is lost, POS can switch to offline mode to continue operations. D is correct because offline mode uses a local database to store transactions. Option A is wrong because offline mode does not provide real-time inventory; it uses cached data. Option C is wrong because offline mode does not improve speed; it may be slower. Option E is wrong because offline mode is not for testing.

Answer

To access real-time inventory data.

Answer

To improve transaction processing speed.

Answer

To test new POS features without affecting the production environment.

Question 12

Refer to the exhibit. A company uses the 'Process inventory reservation' job to manage inventory reservations for online orders. The job is scheduled to run every 5 minutes. At 12:30 PM, a customer places an order but the inventory reservation is not created until 12:50 PM. What is the most likely cause of this delay?

Accepted Answer

The job only processes reservations at its scheduled times, so the order will be processed at 12:50 PM.. The 'Process inventory reservation' job in Dynamics 365 Commerce is a batch job that runs on a scheduled interval. When a customer places an order at 12:30 PM, the reservation is not created until the next scheduled run of the job. Since the job runs every 5 minutes, the next run after 12:30 PM would be at 12:35 PM, but the reservation was not created until 12:50 PM. This indicates that the job is processing reservations only at its scheduled times, and the delay is due to the job's scheduled execution cycle, not a failure or configuration issue.

Answer

The job is not configured to process reservations for online orders.

Answer

The job failed during the last run.

Answer

The job is set to run every 5 minutes but it takes 20 minutes to process.

Question 13

Refer to the exhibit. A product has a tax group of 'WA' and a tax rate of 0.087. The price is set to 29.99. A customer in Washington state purchases this product. What will be the final price including tax?

Accepted Answer

$32.60. Option C is correct because the final price including tax is calculated by adding the tax amount to the base price. The tax amount is $29.99 * 0.087 = $2.60913, which rounds to $2.61 (standard rounding to two decimal places). Adding this to $29.99 gives $32.60. Dynamics 365 Commerce applies tax rounding based on the system's tax calculation settings, typically rounding to the nearest cent.

Answer

$29.99

Answer

$32.59

Answer

$32.48

Question 14

Contoso Retail is a mid-sized company with 50 physical stores and an online store. They use Dynamics 365 Commerce. Recently, they launched a promotion offering 20% off on all electronics for a weekend. During the promotion, the online store experienced slow page load times, and some customers reported errors when adding items to the cart. The IT team checked the infrastructure and found that the Retail Server CPU usage was at 95%, and the channel database had high lock contention. The POS systems in stores were working fine. The company uses a single Retail Server instance and a single channel database for all channels. What is the best course of action to prevent this issue in future promotions?

Accepted Answer

Scale out the Retail Server and channel database to handle increased load.. The issue stems from a single Retail Server and single channel database being overwhelmed by the combined load of online and POS traffic during the promotion. Scaling out the Retail Server (e.g., adding more instances behind a load balancer) and the channel database (e.g., using a dedicated online channel database or scaling up/out the existing one) directly addresses the high CPU usage and lock contention, ensuring adequate capacity for future high-traffic events.

Answer

Disable the online store during promotions to ensure POS performance.

Answer

Configure the online store to use offline mode.

Answer

Reduce the promotion discount to 10% to lower traffic.

Question 15

Northwind Traders operates a chain of grocery stores using Dynamics 365 Commerce. They recently implemented a new loyalty program where customers earn 1 point for every $1 spent, and 100 points can be redeemed for a $5 discount. The program is set up correctly in the headquarters. However, when a customer makes a purchase at a store, the POS does not display the loyalty points earned. The store manager confirms that the customer's loyalty card is linked to the customer account. The IT team verifies that the loyalty program is published to the channel. What is the most likely cause of the issue?

Accepted Answer

The POS screen layout does not include the loyalty points field.. Option B is correct because the POS screen layout controls which fields are visible to the cashier. Even if the loyalty program is correctly configured in Headquarters and published to the channel, the POS will not display loyalty points earned unless the screen layout includes the specific loyalty points field. The store manager confirmed the loyalty card is linked, and the IT team verified the program is published, so the missing field in the screen layout is the most likely cause.

Answer

The 'Process loyalty points' job is not scheduled.

Answer

The customer's loyalty card is not properly linked to the customer account.

Answer

The loyalty program is not published to the store's channel database.
