Study with Arch-303 Actual Test Questions

The Client wishes to implement a third party integration that allows for free shipping If the customer Is a member of the third party service. When the customer's order is exported to the Order Management System (OMS) it also creates a custom object in order to track additional data before sending that order data to the third-party service as well.
What technical concern should the Architect raise to protect performance and stability of the site1?

• A. The customer order quota and related retention or deletion needs.
• B. The customer's order data sent to a third-party and related security needs.
• C. The custom object quota and related retentionor deletion needs.
• D. The OMS having order data sent to a thud party and related security needs.

The storefront integrates with a REST based Address verification service (AVS) that uses token based security. The sequence of calls in the API documentation for this AVS looks like the following
1. Client authentication call, which contains the merchantId and secret in a GET request and returns a token in the response.
2. Address verification call, which contains the token and the address to verify in a POST request.
Once the token is obtained, it is valid for hours and it is not needed to request a new one for subsequent address verification calls, the AVS charges for every request made no matter if it is client authentication call or address verificationcall.
Which three strategies could be applied to allow for efficient use of the service without compromising security? Choose 3 answers

• A. Obtain the token from local storage of the browser and update it once It expires.
• B. Obtain the token from a custom cache before making the client authentication call.
• C. Use HTTPService caching for the client authentication call.
• D. Use a job to store and update the token in a customobject that is used from the storefront code
• E. Apply page caching to the client authentication controller that is used with AJAX.

The Client identifies that a segment of customers need to see some products on the site that other customers should not be able to access. All products are maintained within one catalog but in separate categories. A custom attribute will be used on the Profile system object to identify customers that belong to this special segment. A customer group will be made that is qualified for by this Profile custom attribute. The storefront will be customized to include navigation to relevant categories for this customer group.
Unfortunately during technical review the Client points out that the business teams have raised a concern with maintenance and want to use a shared navigation within the catalog and not use separate categories.
Which item should the Architect suggest to efficiently fulfil this new requirement while maintaining scalability?

• A. Customize theStorefront to use separate storefront catalogs with the same navigation that If the customer Is In the customer group gets assign products appropriately.
• B. Customize the Storefront to modify the search result that if the user is in the customer group thenthe result includes those products appropriately.
• C. Customize the Storefront Co use a hidden search refinement that if the user Is In the customer group then the result Includes those products with a new custom attribute.
• D. Customize the Storefront to use a hidden search refinement and modify the customer group to be qualified for by a new product custom attribute

A new version of the Page Show controller is required for implementation of Page Deserter specific look. It requires implementation of a specific, cache period for Page Designer pages, which b not currently available in the base Storefront Reference Architecture (SFRA) cache.js module What two steps should the Architect instruct the developer to implement?
Choose 2 answers

• A. Create new Page.js controller in client s cartridge. Copy code from base and modify the Page-Show route to include the new cache middleware function.
• B. Create new ceche,js client's cartridge. Copy cache,js from app_storefront_base and add a function for the Page Designer caching.
• C. Create new cache,js in client's cartridge. Extend cache,js from app_storefront_baseand add a function for the Page Designer caching.
• D. Create new Page,js controller in client's cartridge. Extend the code from base and prepend the new cache middleware function to Page-Show route.

The Client wants to have a flashsate on a few products every day. These products are sold through B2C Commerce as well as an in store Point of Sale system that it tied to the same inventory.
An Architect analyzes the following proposed solution:
Inventory feed w*l continue to run dailybut add a web-service call to compare and update B2C Commerce inventory in real time during checkout after a flash product's inventory reaches a threshold.
Which two risks should the Architect communicate to the Client about this solution?
Choose 2 answers

• A. Because the job would still be configured to run daily there will be a degrade in performance during non-flash sales periods
• B. If the externals hosted web-service is unreliable. It could be a point of failure in the site s order placement flow.
• C. The default rate limiter configuration for the web-service could cause the web-service to return an exception during high traffic.
• D. If the product Inventory threshold that triggers the web service calls is reached too often. It will have a negative Impact on site performance.
