Salesforce Updated Platform-App-Builder Exam Questions and Answers by greta

The correct validation rule is:

AND(

ISNEW(),

ISBLANK(Lead.Owner:User.Id)

)

This rule prevents a new Campaign Member from being created when the related Lead does not have a User as owner. Leads can be owned by either a user or a queue, and Salesforce queues can own Lead records.

Salesforce validation rules block a save when the formula evaluates to True. The ISNEW() function checks whether the record is being created, and ISBLANK() checks whether the Lead owner’s User Id is empty.

For owner fields in cross-object formulas, Salesforce requires being explicit about the owner type, such as Owner:User or Owner:Queue .

Why not others:

A is wrong because Lead.Owner.Id is normally populated whether the owner is a user or queue.

B and D focus on queue ownership, but the best exam answer checks that the Lead has an actual User owner when the Campaign Member is created.

The correct answer is D. Flow.

The requirement is to automatically clear the Phone field on Contact when the Do Not Call checkbox is checked. A record-triggered Flow can run when a Contact is created or updated, check whether Do_Not_Call is true, and then update the triggering Contact record by setting the Phone field to blank. Salesforce Flow supports updating records, including directly updating the record that triggered the flow.

B. Validation rule is incorrect because it can block a save but cannot delete or clear the Phone field automatically.

C. Quick action is manual, not automatic.

A. If-then rule is not the best current Salesforce automation tool for this requirement.

===========

The correct answers are A. Use a master-detail relationship between the Park and Trail objects and C. Use a roll-up summary field on the Park record to show the total number of trails .

To show the total number of child Trail records on the parent Park record without code, the app builder should use a roll-up summary field . Salesforce documentation states that roll-up summary fields display values on a master record based on related detail records.

That means Park should be the master object and Trail should be the detail object. Then a roll-up summary field on Park can count the related Trail records.

B is incorrect because standard lookup relationships do not support roll-up summary fields.

D is incorrect because a formula field cannot count multiple child records.

===========

The correct answer is B, based on the intended Salesforce wording.

In a private data model, users normally access records they own or records shared with them. Salesforce role hierarchy opens record access upward: users higher in the hierarchy can view, edit, and report on records owned by users below them, depending on object permissions and hierarchy settings.

Because the Service Coordinator needs access to work orders and related records owned by technicians, placing the SC above the technicians in the role hierarchy gives the required record access without granting excessive org-wide permissions.

Why others are incorrect:

Modify All Data is too broad.

Modify All on Work Order only applies to that object and does not solve access to other related technician-owned records.

Workflow does not grant record access.
