Arch-303 sample questions

Question 1

A global luxury fashion retailer is planning a migration from a legacy platform to Salesforce B2C Commerce. The business requirement dictates a single global storefront that serves 12 countries across North America, Europe, and Asia, supporting 8 languages and 5 currencies. The inventory is managed regionally (Americas, EMEA, APAC) in three separate ERP instances. As the Architect, you must design the technical specification for the site structure and inventory integration.

Which architectural approach best balances the requirement for a unified customer experience with the technical constraints of regional inventory data?

Accepted Answer

Create three separate Sites (Americas, EMEA, APAC) within one Realm sharing a common Master Catalog. Configure distinct Inventory Lists for each site mapped to the respective ERPs, using aliases to present a unified domain structure.

Answer

Design a single Site within one Realm. Use a custom inventory object to aggregate data from all three ERPs and implement complex availability logic in the checkout flow.

Answer

Implement three separate Realms. Replicate the catalog data across all realms and use OCAPI to synchronize cart and session data to simulate a single site experience.

Answer

Design a single Site with one Inventory List. Implement middleware to aggregate real-time inventory calls from all three ERPs into a single feed that updates the list every 15 minutes.

Question 2

During the discovery phase for a high-volume cosmetics brand, the technical architect reviews the client's requirement for a third-party Loyalty Management System (LMS). The client insists on using a specific LMS provider that does not have an existing LINK cartridge. The provider offers a REST API. The integration requires real-time point redemption during checkout and nightly batch exports of order history.

What is the most critical first step the architect should take to evaluate the technical feasibility of this integration?

Accepted Answer

Review the LMS provider's API documentation for response time guarantees, rate limits, and authentication methods to ensure they meet B2C Commerce timeout and security standards.

Answer

Immediately estimate the development effort for a custom cartridge and present the cost to the client.

Answer

Develop a proof-of-concept (POC) integration in a sandbox environment to test the connectivity.

Answer

Advise the client to switch to a loyalty provider that already has a certified LINK cartridge to save time.

Question 3

An architect is creating a Technical Specification for a client who needs to migrate 5 million customer records from a legacy system to Salesforce B2C Commerce. The data includes profile information, address books, and stored payment tokens. The client requires this migration to occur over a weekend cutover window.

Which two artifacts are essential to include in the design documentation for this migration? (Select TWO)

Accepted Answer

A Data Mapping Document detailing the transformation of legacy fields to B2C Commerce system object attributes.

Accepted Answer

A Tokenization Strategy Document outlining how payment tokens will be securely extracted, transformed, and imported without violating PCI compliance.

Answer

A Load Testing Plan to simulate 5 million concurrent users logging in immediately after migration.

Answer

A SEO Strategy Document for customer profile URLs.

Question 4

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?

Accepted Answer

Critical Risk: Bypassing PDP cache for a high-traffic event will likely cause application server saturation and 504 Gateway Timeouts. Recommendation: Refactor to use client-side JavaScript or a remote include with a shorter cache time for the timer only.

Answer

Low Risk: B2C Commerce Application Servers scale automatically, so the bypassed cache will not affect performance.

Answer

Medium Risk: The database might lock. Recommendation: Increase the quota for database connections.

Answer

No Risk: Real-time features are standard in SFRA.

Question 5

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?

Accepted Answer

The impact on page caching, as menus are typically cached globally or by segment, not by individual session.

Answer

The depth of the category tree.

Answer

The limitation of 10,000 categories per site in B2C Commerce.

Answer

The SEO impact of changing category URLs dynamically.

Question 6

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?

Accepted Answer

createRequest

Answer

parseResponse

Answer

mockCall

Answer
