質問 # 46
Although Salesforce B2B Commerce and Salesforce recommend against using
"without sharing classes" whenever possible, sometimes it is unavoidable. Which three items will open up a major security hole? (3 answers)
正解：B、C、E
解説：
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.

A developer has been working on the flow of an Inventory Class for checkout. The developer has handled all the error states and now needs to indicate that inventory is available for all items and amounts in the cart.
Which step should happen next?
正解：A
解説：
To indicate that inventory is available for all items and amounts in the cart, the developer should return sfdc.checkout.InventoryStatus.Status.SUCCESS. The sfdc.checkout.InventoryStatus.Status.SUCCESS is a constant value that represents a successful inventory status. It means that the inventory class has checked the availability of all the products in the cart and confirmed that they are in stock and can be fulfilled. The developer should use this value as the return value of the checkInventory method, which is a method that implements the sfdc.checkout.InventoryCheck interface. The checkInventory method is invoked during the checkout flow to validate the inventory availability of the products in the cart. Returning TRUE is not a valid way to indicate inventory availability, as it is not a valid inventory status value. Returning sfdc_checkout.IntegrationStatus.Status.SUCCESS is not a valid way either, as it is not an inventory status value, but rather an integration status value. Returning sfdc.checkout.InventoryStatus.SUCCESS is not a valid way either, as it is not a valid syntax for accessing the inventory status value.

質問 # 48
Which two statements are true about Global API ' s in Salesforce B2B Commerce? (2 answers)
正解：B、D
解説：
Global APIs are methods that can be called from any Apex class or Visualforce page within the B2B Commerce managed package or subscriber code. Each global API method takes in a Map < String, Object > as a single parameter and returns a Map < String, Object > . This allows for flexibility and extensibility of the API. Global APIs are versioned, which means that they have a version number in their name, such as ccApi_1_0. This ensures backward compatibility and allows for new features and enhancements to be added without breaking existing functionality. Global APIs do not catch any Exceptions that are thrown as part of missingparameters, which means that the caller is responsible for handling any errors or validations. Global APIs do not handle Transaction scope, and the Subscriber calling it does not need to handle scope. This means that the caller can decide whether to use transactions or not, depending on the business logic and performance requirements. Salesforce References: B2B Commerce Developer Guide: Global APIs, B2B Commerce Developer Guide: Global API Versioning
質問 # 49
Which method signature is used in the Global API's?
正解：C
解説：
The method signature that is used in the Global API's is ccrz.cc_Output (ccrz.cc_Input input). This signature indicates that the Global API methods take a single input parameter of type ccrz.cc_Input and return an output of type ccrz.cc_Output. These are custom classes that are defined in the cloudcraze managed package and contain various properties and methods for handling the input and output data. For example, ccrz.ccServiceProduct.getProducts(ccrz.cc_Input input) is a Global API method that takes an input object and returns an output object containing product data.

質問 # 50
How should data for Lightning web components be provided?
正解：B
解説：
Data for Lightning web components should be provided as independent properties that take simpler, primitive values (e.g. String, Number, Boolean, Array). Providing data as independent properties allows the developer to expose data as public or private properties of the Lightning web component and communicate data between components or services. Providing data as simpler, primitive values allows the developer to use data types that are supported by JavaScript and Lightning web components and avoid unnecessary or complex conversions or transformations. Providing data as a few properties that contain sets (objects) of data is not a good way to provide data for Lightning web components, as it can create confusion or inconsistency in data structure and access. Providing data as one property that contains all data in one set (object) is not a good way either, as it can create complexity or inefficiency in data management and manipulation. Providing data as a single property object that contains sets (objects) of data is not a good way either, as it can create redundancy or duplication in data storage and retrieval.
