Explanation:

To grant access to an OCAPI resource in a sandbox or production instance, you must define the required permissions inside the **OCAPI settings JSON file** (typically found in Business Manager under: Administration > Site Development > Open Commerce API Settings).

Two critical fields required to enable access are:
Resource_id: This specifies the path to the OCAPI resource (e.g., /products/*, /baskets/*). Without this, the system doesn’t know which endpoint the permissions apply to.

Client_id: This defines the specific client ID (from Account Manager) that will have access. This ties the permissions to the external application making the API call.

Other optional fields include:

- read_attributes: Controls what fields are returned when reading data (optional, unless you need attribute filtering).
- version_range: Limits what versions of the OCAPI this config applies to (defaults if not specified).

Explanation:

In Salesforce B2C Commerce (SFCC), to log messages to a debug-level custom log file, you use the Logger class from dw/system/Logger. The correct syntax for logging a formatted message to a custom log file is:

var Logger = require('dw/system/Logger');
Logger.getLogger('profile').debug("Error retrieving profile email, Status Code: {0} was returned.", http.statusCode);

This does the following:

📁 getLogger('profile'): Creates or retrieves a custom log file named customdebug-profile-...
🐞 .debug(...): Logs the message at the debug level
🧩 {0}: Placeholder for the first argument (http.statusCode)

🔍 Why Not the Other Options?

A. logger.getLogger(...) Incorrect casing — should be Logger, not logger.
B. logger.debug(...) Missing getLogger() — this logs to the default logger, not a custom file.
C. Logger.getLogger().debug(...) Missing required category name ('profile') in getLogger().

Explanation:

Key Requirement:
Render a Page Designer page in JSON format (e.g., for headless commerce or API responses).

Why Option C?
✅ Correct Syntax for PageMgr.renderPage
The PageMgr.renderPage() method is used to render Page Designer pages programmatically.
To output in JSON, set the renderMode parameter to json:

PageMgr.renderPage(pageID, {
renderMode: 'json',
parameter1: value1 // Additional parameters if needed });

How It Works:
Returns the page structure (regions, components, and data) as JSON.
Used in controllers or scripts to integrate with headless frontends.

Why Not Other Options?
❌ A. PageMgr.serializePage()
Does not exist in the B2C Commerce API.

❌ B. JSON.stringify(PageMgr.renderPage())
Incorrect: renderPage() already returns JSON when renderMode: 'json' is set. Wrapping it in JSON.stringify is redundant.

Explanation:

In Salesforce B2C Commerce, services are configured using three components:

Service Definition (ID, type, etc.)
Service Profile (timeout, logging, retry rules)
Service Credential (username, password, URL)

While the service credential defines the default URL for the service, sometimes during development or sandbox testing, you need to override that URL without changing the credential itself — e.g., for testing with different environments.
To do this, B2C Commerce provides an Override URL feature in the Service Status area of Business Manager.

📌 How to do it:
Go to Business Manager
→ Administration > Operations > Services
Select the service you want to modify.

In the Service Status section, you'll see:
Override URL checkbox
A URL field
✅ Check the “Override URL” box
📝 Enter the custom URL you want the service to call.
Save the changes.
At runtime, the service will use this override URL instead of the one defined in the credential.

❌ Why the other options are incorrect:
A. Use the service credential URL field
🔴 This is the default place to set the URL, but it is not editable dynamically during runtime or testing without affecting the entire credential.
You cannot switch URLs manually on the fly this way.

C. Use a Site preference dedicated for the service URL
🔴 While this is a flexible custom-built solution, it is not required when the goal is to manually override a URL for a service.
Better suited for dynamically switching URLs via code.

D. Use a Global preference dedicated for the service URL
🔴 Same as C — this is custom and unnecessary here.
The built-in override functionality is the correct tool.

🧠 Summary:
To manually change a service URL in a sandbox, use the built-in Service Status override feature in Business Manager. This allows you to test different endpoints without editing credentials or custom preferences.

Explanation:

The log file name is derived from the first parameter passed to Logger.getLogger(). Here’s the breakdown:

Code Analysis:
var log = Logger.getLogger("xyz", "export"); // First param: "xyz", second param: "export" log.info("This is important information");

"xyz": Defines the log file name prefix (e.g., custom-xyz.log).

"export": Specifies the log category (unrelated to the filename).

Business Manager Log Configuration:

The active log category is root (irrelevant here; filename depends on the first parameter).

Log level is info, so the message will be written (since log.info() matches the configured level).

Log File Naming Convention:

Log files follow the format: custom-{firstParameter}.log.
Example: custom-xyz.log.

Why Not Other Options?

A (xyz): Missing the custom- prefix.

B (custominfo-blade): Incorrect; not based on the code.

C (custom-export): Uses the second parameter (category), which doesn’t affect the filename.
