Salesforce Sharing and Visibility Certification Practice Exam

Which method ensures that an Apex class can handle sharing context changes?

1. Create one class that can toggle between contexts as necessary.

2. Separate classes for each sharing context to maintain clarity.

3. Embed SOQL directly in triggers to avoid context issues.

4. Develop utility methods outside of Apex for query execution.

The correct answer is: Separate classes for each sharing context to maintain clarity.

Choosing to separate classes for each sharing context to maintain clarity is a sound method to handle sharing context changes effectively in Apex. This approach allows developers to have distinct, well-defined classes tailored specifically for each sharing context. By doing this, the sharing rules and access levels are clearly articulated in the class design, leading to fewer errors and more maintainable code. When you have separate classes, each can interact with its own set of sharing rules and data access methods without confusion. This structure not only enhances readability but also aligns with the Single Responsibility Principle, which states that a class should have only one reason to change. Therefore, if sharing rules change for a specific context, only the related class needs to be modified. In contrast, a single class toggling between contexts could lead to complex and tangled code, making it harder to manage and understand. Embedding SOQL directly in triggers can introduce difficulties with respect to access level enforcement, leading to potential security concerns. Developing utility methods outside of Apex may also complicate the handling of sharing contexts, as they might bypass the built-in sharing mechanisms intended to control data visibility. Thus, maintaining clarity through separate classes per sharing context is the best practice to follow in this scenario.
