Platform-App-Builder Exam Dumps - Salesforce Certified Platform App Builder (Plat-Admn-202)

The correct answer is B. Add the standard Chatter feed component.

In Lightning App Builder, Salesforce provides a standard Chatter component. Salesforce documentation states that the Feed component was renamed Chatter in Lightning App Builder and is used to place the publisher and feed on a record page.

A is incorrect because a custom Chatter feed component is not needed.

C is incorrect because this does not come from the AppExchange/App College.

D is incorrect because Chatter feed is not added by using the standard related list component.

===========

This question is testing the classic Salesforce Process Builder automation best practice , not a generic Flow-only rule. Salesforce’s official process design guidance states that an org should have only one record-change process per object . The reason is simple: every time a record is created or updated, Salesforce evaluates the record-change processes for that object. If an object has multiple record-change processes, the automation becomes harder to predict, harder to troubleshoot, and more likely to hit governor limits. Salesforce specifically explains that consolidating automation into one record-change process gives admins a single view of all criteria and actions for that object, reduces duplicated automation overhead, and allows the app builder to control the order of criteria evaluation.

A is not the best exam answer here. In modern Flow architecture, “one Flow per object” is often discussed as a design pattern, but it is not the exact best-practice wording being tested by this Platform App Builder-style question. Salesforce Flow design is more nuanced today because record-triggered flows can vary by trigger timing and event. B is wrong because validation rules should be separated by validation requirement, not forced into one rule per object. C is wrong because invocable processes are reusable modular processes, not the main record-change automation container.

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. Deselect auto add to custom report type.

When creating a new custom field, Salesforce provides an Auto Add option that can automatically add the new field to applicable existing custom report types. If the app builder does not want the new field to appear on pre-existing custom report types, they should deselect the Auto add to custom report type option during field creation. Salesforce release documentation confirms that Auto Add automatically adds custom fields to custom report types based on that object.

Why the other options are incorrect:

Removing the field from page layouts only affects record-page visibility, not report type availability.

Changing profile visibility or read-only access affects field security, not whether the field is added to the custom report type layout.

===========

The correct answer is D. Record-triggered flow.

The requirement is automatic: when an Account Type changes to Past-Customer, all directly related Contacts must have their Status updated to Re-Market. A record-triggered flow is the correct declarative automation because it can run when an Account record is updated and then update related Contact records. Salesforce describes record-triggered flows as automation that runs automatically when records are created, updated, or deleted. Salesforce also documents that Flow can update records related to the record that triggered the flow.

Validation rules only prevent invalid saves. Lightning components are UI elements. Screen flows require user interaction, while this requirement needs background automation.
