- Question 1Advanced
Design and Discovery · Site Readiness Assessment
You are conducting a Site Readiness Assessment for a client launching in 3 weeks. You discover that the development team has implemented a custom 'Flash Sale' feature that bypasses the standard SFRA cache for product detail pages (PDPs) to show a real-time countdown timer. The site expects 50,000 concurrent users during the sale.
What is the appropriate risk assessment and recommendation?
Show answer & explanation
Correct answer: D
PDPs are high-traffic pages. Disabling caching on the main controller for a cosmetic feature like a timer during a high-load event is a critical scalability risk. The server cannot generate full HTML for 50k concurrent users. The timer should be handled via client-side logic or a cached remote include.
- Question 2Intermediate
Design and Discovery · Implementation Design Review
A retailer operates a B2C Commerce site with a complex category structure involving 50,000 categories. They plan to introduce a new 'Smart Navigation' feature that dynamically reorders categories in the flyout menu for every user session based on their browsing history.
From a Design and Discovery perspective, identifying which constraint is most critical for the technical specification?
Show answer & explanation
Correct answer: C
Navigation menus are computationally expensive to generate and are usually cached heavily (often part of the page cache or a remote include). Personalizing the menu order per session would render caching ineffective, causing severe performance degradation on every page load.
- Question 3Intermediate
Integrations and Customization · Service Framework Best Practices
A developer is building a custom integration that transmits order data to an ERP system. The ERP requires the order XML to be sent via a SOAP web service. The architect mandates the use of the Service Framework.
Which component of the Service Framework is responsible for converting the internal B2C Commerce Order object into the specific XML format required by the SOAP endpoint?
Show answer & explanation
Correct answer: C
In the Service Framework, the
createRequestcallback method is responsible for preparing the data to be sent. This includes transforming internal objects (like Order) into the payload format (XML/JSON) expected by the external service. - Question 4Advanced
Design and Discovery · Integration and Data Analysis
You are reviewing a proposed architecture for a headless commerce implementation. The client wants to use a React-based Single Page Application (SPA) for the storefront but use B2C Commerce for the backend (PIM, Pricing, Promotions, Checkout). They plan to use the Shop API (OCAPI) for all interactions.
Which limitation of OCAPI should be highlighted as a primary concern for the SEO strategy of the SPA?
Show answer & explanation
Correct answer: D
In a headless architecture using OCAPI, the B2C Commerce platform returns JSON data, not HTML. Search engine crawlers (historically) have difficulty indexing purely client-side rendered SPAs. The architecture must include an SSR layer (like Node.js) or a prerendering service to deliver indexable HTML to bots, which adds complexity compared to SFRA.

Design and Discovery · Integration and Data Analysis
CASE STUDY
Company Background
StyleVibe is a fast-fashion retailer launching a new B2C Commerce site. They have a massive product catalog (2 million SKUs) with high turnover.Current Situation
The catalog team updates product descriptions, pricing, and inventory in their PIM and ERP systems every hour. They expect these updates to reflect on the storefront within 15 minutes of the update.Technical Constraint
The middleware team has exposed a REST API that B2C Commerce can poll for delta updates, but they also support generating a full CSV export dropped onto an SFTP server once a day.Requirement
Design the data integration strategy to meet the 15-minute freshness requirement without degrading storefront performance.Which integration pattern is most appropriate?
Show answer & explanation
Correct answer: D
To meet the 15-minute freshness requirement, a frequent polling mechanism is needed. Since the source provides a delta API, a scheduled Job running every 10 minutes is efficient. It avoids the overhead of full catalog imports and keeps data fresh. The standard Import framework is for files; for API-based deltas, a script-based job is appropriate, provided the delta volume is manageable.

Monitoring and Troubleshooting · Performance Issue Resolution
CASE STUDY CONTINUED
Following the implementation of the delta update job for StyleVibe, the team observes that during peak hours, the job sometimes fails with a
QuotaViolationException. The analysis shows that the number of modified products in a 10-minute window occasionally exceeds the governance limit for object modifications in a script.What is the best architectural adjustment to resolve this stability issue while maintaining data freshness?
Show answer & explanation
Correct answer: C
Script-based object modifications (ORM) have stricter quotas than the standard Import framework. By switching to a file-based import approach (even for deltas), the system leverages the highly optimized, bulk-processing capabilities of the standard Import pipelets, which effectively bypass the script-level object modification limits.
