E.
Executing dynamic SOQL inside a without sharing class with a bind variable fromccAPI.CURRENT_VERSION.
Answers
Suggested answer: A, C, D

Explanation:

Executing dynamic SOQL inside a without sharing class with a bind variable from PageReference.getParameters(), PageReference.getCookies(), or cc_RemoteActionContext class will open up a major security hole because these sources of input are not sanitized and can be manipulated by malicious users to inject SOQL queries that bypass the sharing rules and access data that they are not supposed to see. For example, a user can modify the URL parameters or cookies to include a SOQL query that returns sensitive data from the database. To prevent this, it is recommended to use static SOQL or escape the bind variables before executing dynamic SOQL.

C.
HTML does not support <span> tags inside the <head>
Answers
Suggested answer: A

Explanation:

The ccrz.cc_hk_UserInterface apex class is preferred over the HTMLHead Include Begin and HTML Head Include End Cloudcraze Page Include sections because Salesforce apex:include is wrapped in <span> tags, which are not valid inside the HTML <head> tag. This can cause rendering issues or unexpected behavior in some browsers. The ccrz.cc_hk_UserInterface extension allows adding content to the HTML <head> tag without using apex:include.

Answers
Suggested answer: A, D

Explanation:

The ccUtil apex class provides two methods to check the input or return data of the Global API's: ccrz.ccUtil.isNotEmpty(Map<String, Object>) and ccrz.ccUtil.isEmpty(Map<String, Object>). These methods return true if the map is not null and contains at least one entry, or if the map is null or empty, respectively. Similarly, ccrz.ccUtil.isNotEmpty(List<Object>) and ccrz.ccUtil.isEmpty(List<Object>) return true if the list is not null and contains at least one element, or if the list is null or empty, respectively. These methods are useful for validating the input parameters or the output results of the Global API's.

Answers
Suggested answer: A

Explanation:

To ensure that a custom field is available to display on a given page, the Developer needs to override the Service Class that the page uses and update the Service Management in CCAdmin for the given storefront to use this new Service Class. The Service Class is responsible for retrieving and setting data for a given page. The Logic Class is responsible for implementing business logic and validation rules for a given page. Creating a new Service Class or Logic Class is not necessary, as overriding an existing one can achieve the same result. Salesforce

Answers
Suggested answer: B, D

Explanation:

It is preferable to extend the Salesforce B2B Commerce remote invocation object instead of using the standard Salesforce remote action invocation manager for two reasons:

The APEX method called by the remote action will be passed as a Salesforce B2B Commerce context object, which contains useful information such as the current user, cart, storefront, and configuration settings. This can simplify the development and testing of the remote action.

The Salesforce B2B Commerce logger can be utilized in the remote action, which allows logging messages and errors to the debug log or to a custom object. This can facilitate debugging and troubleshooting of the remote action.
