The correct answer is B. Validation Rule.

DreamHouse Realty wants to prevent an Opportunity from entering the Qualified stage unless Expected_Close_Date__c is populated. A validation rule is the correct tool because Salesforce validation rules check whether record data meets specified criteria before the user can save the record.

A validation rule could check:

Stage = Qualified

AND

Expected_Close_Date__c is blank

If both are true, Salesforce blocks the save and displays an error message.

A. Page Layout can make a field visible or required on a layout, but it cannot conditionally require the field only when Stage equals Qualified.

C. Activity History is unrelated.

D. Record Type controls business processes and layouts but does not enforce this condition by itself.

===========

The formula must evaluate true when:

Stage = Negotiation/Review

Close Date < 1 week from today

Salesforce formula functions used:

ISPICKVAL() for picklist equality checks

AND() to combine multiple conditions

CloseDate < TODAY() + 7 to check the Close Date is within one week

Correct formula:

AND(

ISPICKVAL(StageName, " Negotiation/Review " ),

CloseDate < TODAY() + 7

)

Options A, C, D use invalid syntax (missing quotation marks, incorrect function structure).

Salesforce Help confirms correct syntax for picklist comparison and date arithmetic in formula fields. (Salesforce Help)

This formula evaluates true only when both conditions are simultaneously met.

===========

The correct answer is D. Roll-up summary field.

Cloud Kicks wants to display a count of related Opportunities on the Account record where the Opportunities are Closed Won and have a Close Date within the last year. A roll-up summary field is the correct declarative feature because it calculates values from related records, including counts, sums, minimums, and maximums. Salesforce documentation confirms that roll-up summary fields calculate values from related records and can display values on the parent record.

The app builder can create a roll-up summary field on Account with filter criteria such as:

Stage = Closed Won

Close Date = Last 365 Days / Last Year

Why others are incorrect:

Activity timeline displays activities, not Opportunity counts.

Formula field cannot count multiple child Opportunity records.

Validation rule blocks invalid saves; it does not calculate related record totals.

===========

The correct answer is D. Approval process.

The marketing director wants all free parts to receive sign-off before they are allowed. Salesforce Approval Processes are used to automate how records are approved, define who approves at each step, and specify actions after approval or rejection. Trailhead describes approval processes as automation for record approval and explains that approval steps assign approval requests to specific users.

Chatter approval is not the standard feature for formal record sign-off. Slack post and automated email message can notify people, but they do not enforce approval. An Approval Process is the correct declarative feature for required business sign-off.
