Explanation:

To allow access to product inventory records via the Open Commerce API (OCAPI), especially with URLs like:
/dw/data/v18_3/inventory_lists/ecom-inventory/product_inventory_records/00893408601
…the developer must ensure that the inventory_list resource is enabled in the Data API OCAPI settings.

✅ Why “Inventory_list” is Correct
This URL is part of the Data API and references:
The resource inventory_list
A specific inventory list ID (ecom-inventory)
A product SKU (00893408601)

In Business Manager, under:
Administration > Site Development > Open Commerce API Settings > Data API

the developer should confirm that:
The inventory_list resource is present in the JSON config
It includes the necessary read (GET) permissions
The associated client_id is assigned to the correct scopes

❌ Why the Other Options Don’t Apply
A. Client_id
Not a resource — it's a credential identifier used to access APIs. Needs to be valid, but doesn’t control access to specific endpoints.
B. Ecom-inventory
This is a resource identifier (an instance of inventory_list), not a resource type itself.

🔗 Reference:
“The Open Commerce API (OCAPI) uses resource-based access control. To use inventory endpoints, the inventory_list resource must be enabled with the required methods (e.g., GET) in the Data API settings.” — Salesforce B2C Commerce Developer Guide

Explanation:

To meet the requirement of tracking customer interest in out-of-stock products and sending notifications when they’re back in stock, the best approach is to use a custom object. This allows you to:

Store SKUs of out-of-stock products the customer is interested in
Store the customer’s email address, whether they are registered or a guest
Query and trigger notifications when inventory is replenished

✅ Why use a custom object?
Flexible schema: You can define attributes like skuList, email, timestamp, status, etc.
Site-independent or site-specific: Can be scoped globally or per site
Easily queried: For batch jobs or real-time triggers
Avoids polluting system objects like Profile or Product

❌ Why the other options are incorrect

A. Add to Profile object Not suitable for guest users, and misuses the Profile object for transactional data.

B. Create a new system object type You cannot create new system object types — only custom object types.

D. Add emails to Product object This violates data separation principles and doesn’t scale well. Products should not store customer-specific data.

Explanation:

When a logical error is suspected in a Salesforce B2C Commerce script, the most effective way to locate and understand the issue is to:

Use the Script Debugger (available in sandbox environments).

Set breakpoints at key lines of code.

Step through execution to observe control flow and variable values.

Evaluate expressions to confirm whether logic behaves as expected.

This approach allows the developer to pinpoint exactly where the logic deviates from expectations — whether due to incorrect conditions, unexpected data, or flawed assumptions.

❌ Why the other options fall short:

A. Submit a support ticket: Support can help with platform issues, but not with custom logic bugs in your code.

B. Check request logs: Useful for runtime errors or stack traces, but not ideal for tracing logic flow.

D. Print values in a previous script node: May help in pipelines, but doesn’t offer the precision or control of a debugger.

Explanation:

What setFilteredByFolder(false) Does:
The method apiContentSearchModel.setFilteredByFolder(false) disables folder-based filtering in Page Designer content searches.
When set to false, the search will include content assets regardless of whether they are stored in folders or not.

Why Option A is Correct?
This allows merchants or developers to find Page Designer content (pages, components, etc.) even if they are not organized in folders.
By default, searches might be restricted to specific folders, but this setting broadens the search scope.

Why Not the Other Options?

B. Incorrect – The method does not prevent content from being searchable; it expands searchability.
C. Incorrect – It does not separate results into folders; it ignores folder restrictions.
D. Incorrect – It does not extend ContentSearchModel; it simply modifies search behavior.

Explanation:

Logging Hierarchy & Configuration:

The logger is initialized with:
var logger = Logger.getLogger("loggerFile", "category1.eu");

category1.eu is a child of category1 (which is configured for WARN level in Business Manager).

Since no explicit level is set for category1.eu, it inherits the WARN level from category1.

Log File Naming:

Custom log files follow the format:
custom-{loggerName}.log
Here, loggerName = "loggerFile", so the file will be:
custom-loggerFile.log

Why the Log is Written:

The logger.warn() call matches the WARN level enabled for category1 (inherited by category1.eu).

Why Not Other Options?

A: Incorrect. The log level (WARN) is enabled for category1.eu via inheritance.

B: Missing the custom- prefix.

D: Incorrect prefix (customwarn is not a valid format).
