'Technology', while also retrieving the Contact's Job_Application__c records.

NEW QUESTION # 236
Given the following code snippet, that is part of a custom controller for a Visualforce page:

In which two ways can the try/catch be enclosed to enforce object and field-level permissions and prevent the DML statement from being executed if the current logged-in user does not have the appropriate level of access? Choose 2 answers

Answer: A,B

Explanation:
A: if (Schema.sObjectType.Contact.isUpdatable()) - This checks if the Contact object is updatable for the current user. B. if (Schema.sObjectType.Contact.fields.Is_Active__c.isUpdateable()) - This checks if the Is_Active__c field on the Contact object is updatable for the current user.
These checks should be performed before executing DML statements to ensure that security is not bypassed.
C and D are incorrect because: C. It only checks if the Contact object is accessible, not whether it's updatable.
D: Checking ownership does not necessarily enforce field-level and object-level permissions.

I also noticed that you sent me an image along with your question. It seems to be a snippet of code written in Apex, which is used for copyright development. It shows a public method named updateContact that accepts a Contact object as a parameter. Inside this method, there's an assignment operation where Is_Active__c field of thisContact object is set to false. A try/catch block follows where an attempt to update thisContact record occurs within try; any exceptions caught during this process are handled in catch block. If an exception occurs during update operation, an error message string gets concatenated with exception's message and displayed using ApexPages.addmessage.
