B2C-Commerce-Architect Sample Questions Answers

When integrating a new brand's ecommerce site into an existing realm, the architect needs to ensure that product data and inventory from the new brand's Enterprise Resource Planning (ERP) system are correctly managed within the realm. Therefore, creating new import jobs for products (Answer B) and inventory (Answer C) is essential. These import jobs will facilitate the synchronization of the new brand’s product catalog and inventory levels with the existing Order Management System (OMS) and Customer Relationship Management (CRM) systems of the realm. Such integration is crucial for maintaining up-to-date product and inventory information across the systems, ensuring seamless operations and data consistency.

The appropriate tool to verify that the problem is indeed caused by the inventory check at the beginning of checkout is the Pipeline Profiler in Business Manager. This tool allows an architect to analyze the performance of specific code execution paths, including those involving third-party API calls. It helps identify bottlenecks and inefficiencies in the pipeline execution, particularly useful in situations where custom code like inventory checks may impact site functionality. The use of the Pipeline Profiler would enable the architect to pinpoint if the custom inventory check is causing the checkout process to fail or redirect users inappropriately.

When integrating a new Payment Service Provider (PSP) LINK cartridge designed for SiteGenesis Pipelines into a site built on Controllers, consider these options:

• Option A (Estimate the effort and risk to convert the LINK cartridge from pipelines to controllers): Assessing the effort involved in converting the cartridge provides insight into the project scope, helping to manage risk and allocate resources effectively.
• Option B (Reach out to the PSP development team and ask if a new cartridge version that supports controllers is under development): This can potentially save significant development time and resources if a compatible version is already planned or in progress.

These approaches help in making an informed decision on integration strategies, balancing between customization efforts and leveraging existing solutions.

When integrating a third-party service that relies on custom objects in B2C Commerce, the primary technical concern is the impact on performance and site stability related to the usage of these objects. Important considerations include:

• Custom object quota: Ensuring that the use of custom objects does not exceed platform limits, which could impact performance or even prevent new data from being stored.
• Retention or deletion needs: Proper management of custom object lifecycle is crucial to prevent data bloat and maintain database performance, including strategies for timely deletion or archiving of old data.

Addressing these concerns is critical to maintaining the performance and stability of the site while integrating third-party services that require extensive data handling.

The risks associated with the proposed real-time inventory update solution during flash sales are:

• Option A (The default rate limiter configuration for the web-service could cause the web-service to return an exception during high traffic): This is a critical risk because high traffic during flash sales could exceed the rate limits set for the web-service, leading to exceptions and potentially failing to update inventory in real-time.
• Option B (If the external hosted web-service is unreliable, it could be a point of failure in the site’s order placement flow): Reliance on an external web-service for crucial operations like inventory updates introduces a risk of downtime or performance issues if the service is unreliable, directly impacting the ability to complete orders during peak sales periods.

Both risks could severely disrupt operations during critical sales events, suggesting a need for robust contingency plans and potentially reevaluating the solution architecture to ensure reliability.

For logging practices in a complex LINK cartridge integration, the recommendation is:

• Get logger for cartridge-specific category (C): This practice allows for more precise and relevant logging by focusing on the specific cartridge, making troubleshooting more efficient.
• Report debug level message for the back-end asynchronous communication: This ensures that all detailed interactions are logged, providing valuable data for diagnosing issues.
• Report all errors at error level message: This categorizes all critical issues under error logs, which is essential for quick identification and resolution of problems affecting the system's operations.

This structured logging strategy enhances the ability to monitor and troubleshoot the system effectively, especially in complex integrations where multiple components interact asynchronously.

To fulfill the requirements of having multiple static image content areas, a carousel of featured products, and dynamic content adjustments based on the time of year:

• Option C (Leverage B2C Commerce content slots and assets): This solution allows for dynamic content management where different assets and slots can be used to manage and display static images, text overlays, and other content variations effectively.
• Option D (Leverage B2C Commerce Page Designer with a dynamic layout): Using the Page Designer with a dynamic layout enables the easy assembly of complex page designs, including carousels and responsive elements that adjust based on viewing device or other criteria like time of year. This tool provides the flexibility required for real-time customization and resizability of page elements.

These solutions provide robust and flexible management of site content that meets the business's needs for a visually engaging and adaptable homepage.

In a production environment, logging sensitive customer information such as credit card details (PAN, CVV, expiration date) can lead to severe security and compliance issues, specifically violating PCI DSS (Payment Card Industry Data Security Standard) requirements. The standards strictly prohibit the storage of CVV codes and mandate that any PAN displayed must be masked. Storing such data in logs is not only a risk for data breaches but also non-compliance with these standards can lead to penalties.

• Option A: Including the customer's card name along with the full credit card number in logs is a clear violation of PCI DSS requirements, which stipulate that no more than the last four digits of the card number may be displayed.
• Option B: Logging the card security code (CVV) and expiration date is explicitly prohibited by PCI DSS, which requires that sensitive authentication data, including CVV, must never be stored post-authentication, even if it is encrypted.

For implementing CSRF (Cross-Site Request Forgery) protection correctly, especially in forms like promotion code submissions during checkout, best practices include:

• Option A (Ensure the CSRF protection is validated on form submission): It is crucial to validate the CSRF token upon the form's submission to ensure that the request originates from a legitimate source and corresponds to the user's intended actions, enhancing security against CSRF attacks.
• Option D (Only use POST methods over HTTPS): Using POST methods for transmitting form data helps mitigate the risk of CSRF attacks as opposed to GET methods which can be manipulated more easily via URL. Ensuring the communication is overHTTPS encrypts the transmission, securing the data from interception or tampering during transit.

These practices safeguard against common security vulnerabilities and ensure that the application adheres to secure coding standards.

This design maximizes efficiency and concurrency. By having the jobs that import products, stores, prices, and content run in parallel, the system can handle multiple data streams simultaneously, reducing total processing time. The sequential execution of importing categories followed by reindexing ensures that all new and updated information is properly indexed and available for site use, following the completion of the import of more frequently updated data. This order respects dependencies between steps and aligns with best practices for handling complex data workflows in B2C Commerce environments.

To implement a specific cache period for Page Designer pages in SFRA:

• Option Ainvolves creating a new Page.js controller in the client’s cartridge, where the existing Page-Show route can be modified to include a custom caching logic. This ensures that the specific caching requirements for Page Designer pages are met without altering the base functionality for other pages.
• Option Dcalls for extending the existing cache.js module in the client’s cartridge to include a function specifically for Page Designer caching. This allows for reusing the existing caching logic while adding enhancements specific to the Page Designer pages, thus maintaining efficiency and clarity in the codebase.

Both options provide a clean, maintainable approach to customizing caching for specific requirements in SFRA, avoiding disruptions in other areas of the site functionality.

Considering the existing metrics and forecasted 300% growth, the appropriate load testing targets for the new B2C Commerce site would be:

• 15000 visits per hour: This figure is calculated by applying the expected growth to the peak visits per hour (1000 visits), resulting in 4000 visits. The choice of 15000 provides a higher buffer to accommodate unforeseen spikes in traffic.
• 300000 page views per hour: Similarly, this is scaled up from the peak page views per hour (20000) considering the growth, ensuring the site can handle high demand and interactions.
• 3750 orders per hour: This target is based on the peak orders per hour (250) with the growth applied, allowing testing of the system's ability to handle transactions under significant load.

These targets ensure that the system is robust enough to handle increased traffic and transactions without performance degradation, crucial for maintaining customer satisfaction and operational stability.

If multiple hook.js files are referring to the same basket calculation hook within a LINK cartridge integration, it could lead to the hook being executed multiple times during a single tax call. This often occurs due to redundancy in the integration, where multiple scripts are set to trigger the same function, inadvertently causing duplicate calculations. It's essential to ensure that only one script is responsible for invoking specific hooks to prevent this kind of redundancy and inefficiency in the system.

When integrating a new LINK cartridge for a customer service provider, the following documents are essential:

• Option A (Document the design of implementing a new B2C Commerce cartridge following the industry standard best practices): This ensures that the cartridge is implemented in a manner that is consistent with established best practices, enhancing maintainability and compatibility.
• Option B (Document the data objects, the interface, and data synchronization frequency between the systems): It's crucial to define how data will flow between the new customer service provider and the commerce system, including the frequency of synchronization to ensure data integrity and timeliness.
• Option D (Document the customizations required on top of the LINK cartridge based on current commerce implementation and business needs): Customizing the cartridge to fit the specific needs and existing setup of the commerce system ensures that the integration adds the intended value without disrupting existing operations.

These artifacts will guide the structured integration and customization of the LINK cartridge, ensuring it meets the business's operational and strategic needs.

In the provided configuration, the incorrect statement is B. While it appears that the hostnamewww.example.comshould redirect towww.example.com/usbased on the"if-site-path": "us"entry, this assumes that the default path or redirect isn't overridden by other configurations within the hostname alias file not visible in the snapshot provided. Typically, in Salesforce B2C Commerce, such a direct statement about redirection should align with explicit mapping rules that include hostname and path directives, which are not detailed forwww.example.comtowww.example.com/usin the snippet provided. This absence suggests that the statement may be incorrect unless corroborated by additional detailed mappings in the full configuration file.

When facing build failures that are not reproducible in developers' environments, a common and effective first step is to clean up the build server workspace (Answer A). This action clears any residual files, settings, or data that might be influencing the build process and causing discrepancies between local and server builds. By resetting the workspace to a clean state, it helps ensure that the build process is starting from a consistent base, potentially resolving issues caused by stale data or corrupted build artifacts. This step often resolves hidden configuration or environment-specific issues that are not immediately apparent in the code or module versions.
