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

The correct answer is D. Approval process with a record-triggered flow.

Salesforce does not provide a simple “approval before delete” button behavior by default. The practical declarative pattern is to use an Approval Process for manager permission and a record-triggered Flow to automate the submit/delete logic. Flow includes a Submit for Approval action for Classic Approval Processes and also supports deleting records through the Delete Records element.

Why not the others:

A two-step approval process only handles approval routing; it does not complete the deletion automation by itself. A scheduled path or schedule-triggered flow is not appropriate because this is based on a user’s delete request, not a time-based batch process.

The correct answer is B. Unable to reference the child records.

Formula fields can reference fields on related parent records through cross-object formulas. For example, a formula field on Contact can reference Account fields because Account is the parent of Contact. Salesforce Trailhead shows this pattern by inserting Contact | Account | Account Number in a formula on Contact.

However, the reverse direction is not supported in a normal formula field. An Account formula cannot directly reference values from multiple related Contact child records. Since Contacts are child records of Account, the Contact relationship does not appear in the Account formula editor.

A is incorrect because the issue described is about relationship direction, not the number of formula fields.

C is incorrect because Contact and Account do not need a master-detail relationship for this limitation to apply.

D is incorrect because Salesforce formula character limits are separate from this parent-to-child reference limitation. Salesforce documents formula character limits separately.

===========

The correct answers are B. AppExchange and D. Lightning Components.

Salesforce Trailhead states that custom Lightning components can be created with Lightning Web Components or Aura, and existing Lightning components can also be installed from the AppExchange. Custom components configured for Lightning App Builder appear in the Lightning Components pane and can be added to Lightning pages.

Why others are incorrect:

A. Import Wizard is a data import tool, not a source of UI components.

C. Apex Code provides server-side logic, but Apex itself is not a Lightning page component resource.

===========

A before-save record-triggered flow is optimized for updating fields on the same record that initiated the automation. The flow can trigger when an Opportunity is updated, test whether StageName changed, and assign the current date directly to Stage_Last_Changed__c . Salesforce recommends before-save flows for updating fields on new or changed triggering records because the changes are applied before the database save and avoid an additional DML operation. Salesforce also confirms that values assigned to the triggering $Record are automatically persisted. A scheduled path would introduce an unnecessary delay, while an approval process does not fit a simple field-stamping requirement. An autolaunched flow invoked manually would depend on user action and therefore could not reliably guarantee that every Stage change is captured.
