Salesforce Sharing and Visibility Certification Practice Exam

Which two methods would enforce user permissions on creating records and accessing certain fields in Visualforce?

1. Schema.DescribeFieldResult

2. Schema.getGlobalDescribe

3. UserInfo.getProfileID

4. Schema.DescribeSObjectResult

The correct answer is: Schema.DescribeFieldResult

To enforce user permissions on creating records and accessing certain fields in Visualforce, utilizing Schema.DescribeFieldResult is a robust choice. This method provides detailed information about a specific field in an object, including its accessibility for the current user's profile. It can determine whether a user has read or edit access to that field, which allows developers to tailor the visibility and editability of form fields based on the user's permissions effectively. When a Visualforce page invokes this method, it can check field-level security settings, ensuring that users do not unintentionally interact with fields they are not permitted to access or modify. This is crucial for maintaining data integrity and adhering to security best practices within the Salesforce environment. The other options do not serve the same function. For example, getGlobalDescribe provides metadata about all objects in the organization but does not focus on user permissions at the field level. UserInfo.getProfileID retrieves the profile ID of the current user but does not directly evaluate specific user permissions against individual fields or records. DescribeSObjectResult gives metadata about an entire object but similarly lacks the granularity needed for field-level permission checks.
