Developers Changed CRT-450 Questions

 A developer can use a validation rule or a trigger to prevent Opportunities from being edited when they reach the Closed/Won stage. A validation rule can check the stage value and display an error message if the user tries to modify the record. A trigger can also check the stage value and throw an exception if the user tries to update the record. Both of these strategies can enforce the business logic at the database level and prevent unwanted changes.

An after-save flow or the Process Automation settings are not suitable for this requirement, because they are executed after the record is saved to the database. They can perform actions based on the record changes, but they cannot prevent the record from being edited in the first place.

The value of the count field after inserting an Account with an initial value of zero is 2, because both the trigger and the workflow rule will increment the count field by 1. The order of execution for this scenario is as follows:

• The Account record is inserted with a count value of 0.
• The system runs the before insert trigger, which increments the count value to 1.
• The system saves the record to the database, but does not commit yet.
• The system runs the after insert trigger, which does not affect the count value.
• The system executes the workflow rule, which increments the count value to 2.
• The system updates the record again with the new count value.
• The system commits the record to the database.

The field update in the workflow rule is configured to not re-evaluate workflow rules, which means that the workflow rule will not be triggered again by the second update. Therefore, the count value will remain 2.

The correct answer is option C. In Salesforce, a custom SOAP Web Service is defined using Apex with annotations that enable classes and methods to be exposed as web service endpoints. Helper methods that are not used by the Web Application should not be declared as webservice. They can be private or public but should not have the webservice keyword in their declaration. The webservice keyword is specifically for methods that are exposed to external applications via SOAP API.
