Comm-Dev-101 Exam Dumps : Salesforce Certified B2C Commerce Developer

B2C Commerce allowsmultiple modules to be registered for the same extension point, including multiple registrations in a singlehooks.jsonfile. Salesforce explicitly documents this behavior. When the extension point is invoked, all registered modules are executed rather than stopping after the first implementation.

Option B is incorrect as stated for modules registered together in one hook configuration: Salesforce states that the developer cannot explicitly control their execution order through the registration itself. Across cartridges, however, hook execution follows cartridge-path order, so cartridge precedence can affect the sequence in which implementations from different cartridges execute. Option C is also incorrect because Salesforce specifies that when multiple hook modules are called,the last hook ' s return valueis the return value that is ultimately used—not the first hook ' s return value. All registered implementations still execute even if earlier implementations return values.

This behavior is important when several cartridges extend the same business process. Developers must design hooks to coexist without assuming that their implementation is the only one registered.

===============

The cartridge ' s root-levelpackage.jsonuses the " hooks " property to point to the hook registration file. In the standard SFRA cartridge structure, the hook-registration file resides under:

cartridge/scripts/hooks.json

Therefore, the correct relative path is:

{ " hooks " : " ./cartridge/scripts/hooks.json " }

Salesforce ' s SFRA hook documentation confirms thatpackage.jsonuses thehookskeyword to identify the hook file and that the referenced hook file then maps extension-point names to script implementations.

Option B omits thecartridgeportion of the normal directory structure, so it points to the wrong location. Option C uses JavaScript-object syntax rather than valid JSON because thehooksproperty name is unquoted. Apackage.jsonfile must contain valid JSON.

Thehooks.jsonfile contains entries with the extension-pointnameand correspondingscriptmodule. Once the cartridge is deployed and active on the appropriate cartridge path, registered hooks can participate in storefront or platform extension points.

===============

Uploading a cartridge to an instance does not automatically make its code available to a storefront. B2C Commerce resolves application resources according to thecartridge path configured for the relevant site. Consequently, the new custom cartridge must be added to that storefront site ' s cartridge path, normally in the correct precedence position relative to SFRA base and other cartridges.

Salesforce ' s cartridge documentation describes two distinct steps: upload the cartridge code and register the cartridge with the applicable site through its cartridge path. Site configuration is performed from the site ' s settings, where the cartridge path controls which controllers, templates, scripts, models, and other cartridge resources can participate in storefront execution.

Rebuilding indexes is unrelated unless the customization specifically changes indexed catalog/search data. An index rebuild does not register executable storefront code. Likewise, configuring the Business Manager application ' s cartridge path would affect Business Manager customizations rather than the customer-facing storefront identified in the question.

Cartridge ordering is also significant because B2C Commerce searches the path according to precedence, enabling custom cartridges to extend or override functionality from cartridges located farther to the right.
