Question #1
A Digital Developer is working on a project to convert a pipeline to a JavaScript controller. UX Studio has a functioning pipeline debugger configured for the site. Assume the Developer will add a breakpoint to the controller when it is written. What must be done in order to use the debugger with the new controller when it is written?
Correct answer: A
Explanation
UX Studio debugs JavaScript controllers through a script debug configuration, so a new configuration must be created for the controller. The existing pipeline debugger, even modified, cannot attach breakpoints to controller script.

Additionally, authenticated users who try to add a coupon are logged out. The following processing code is found in the Cart.js controller file: What should the Developer verify to identify the issue?

Correct answer: C

What is the next step in Business Manager to create “The Basics” as a combination?

Question #7
A Digital Developer suspects a logical error in a script. Which action will help locate the error?
Correct answer: C
Explanation
Setting breakpoints, stepping through the script and examining variable values reveals where the logic goes wrong. Request logs show evidence of failures rather than faulty logic, and support tickets or printing values in an earlier node do not locate the error.

Question #8
A Digital Developer needs to add logging to the following code: Which statement logs the HTTP status code to a debug-level custom log file?

Correct answer: D
Explanation
The Logger class is used with getLogger(category), and the category determines which custom log file receives the message, with {0} holding the status code argument. The lowercase logger calls and getLogger() without a category cannot target a named custom log file.

Question #9
A Digital Developer has been given a requirement to add fault tolerance to an existing web service integration that uses Service Framework. Administrators at Universal Containers need to be able to configure the timeout and rate limiting. Which approach should the Developer use to implement the requirement?
Correct answer: A
Explanation
With the Service Framework, timeouts and rate limits are configured by administrators on the service profile; when a limit or circuit breaker trips the call throws ServiceUnavailableException, which the code catches to run fallback logic.

Question #10
A Digital Developer is implementing an Open Commerce API call to add products to a basket. Given the following resource configuration: Which modification allows the requests to successfully execute?

Correct answer: A
Explanation
Adding items requires the resource to cover the basket's items sub-resource, so resource_id must be /baskets/*/items rather than the basket resource alone.
