Salesforce Certified Advanced Administrator — Question 151

The VP of Finance wants to ensure that once an opportunity is closed, it cannot be modified by any user.
How can an administrator meet this requirement?

Answer options

• A. Create a workflow field update to update the IsClosed field to True if a closed opportunity is modified
• B. Set the Do Not Modify Closed Opportunity permission for all profiles
• C. Set all fields to Read-Only on the standard Closed Opportunity page layout
• D. Create an opportunity validation rule with the formula: PRIORVALUE(IsClosed) = True

Correct answer: D

Explanation

The correct answer is D because creating a validation rule that checks if the IsClosed field was True before any modification prevents changes to closed opportunities. Option A is incorrect as it does not prevent the modification but rather updates the field. Option B is not valid because permissions cannot be set universally for all profiles in a way that completely restricts modifications. Option C is also incorrect since making fields Read-Only does not enforce a hard stop on modifications; it just alters the user interface.
