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

The correct answer is A. Import Wizard.

Cloud Kicks needs to insert 25,000 records and use deduplication for a custom object. Salesforce Trailhead states that the Data Import Wizard can import data into custom objects and supports up to 50,000 records at a time, so 25,000 records fits within the Import Wizard limit.

Salesforce Help also states that the Data Import Wizard prevents duplicate custom object records by matching records against fields such as the custom object name or Salesforce ID.

B. Data Loader is not the best answer because Data Loader is better for larger or automated loads, but this question specifically requires deduplication and only 25,000 records. C. Lightning Object Creator creates objects from spreadsheets; it is not the correct deduplication import tool. D. Schema Builder is for creating and viewing data models, not importing records.

===========

The correct answers are B. Apex and C. AppExchange.

Cloud Kicks needs to count related Case records on Account based on open and closed status. Standard roll-up summary fields work only in supported roll-up relationships, mainly master-detail relationships. Salesforce documentation states that lookup relationships do not support roll-up summary fields.

Because Cases are related to Accounts through a lookup-style relationship, native roll-up summary fields are not the best available option in this answer set. The app builder can meet the requirement by using:

Apex — Apex triggers can run before or after record changes such as insert, update, or delete, allowing custom logic to recalculate the open and closed Case counts on the Account.

AppExchange — AppExchange roll-up tools, such as lookup roll-up packages, can summarize records across lookup relationships without building custom code.

Why others are incorrect:

Validation Rule prevents invalid data entry; it does not calculate related record counts.

Approval Process routes records for approval; it does not summarize Case counts.

===========

The required metric is the total monetary value of won Opportunities for each Account. Salesforce supports roll-up summary fields on Account that aggregate Opportunity Amount and apply filtering criteria so that only qualifying child records are included. The appropriate configuration therefore uses SUM on Opportunity Amount with a filter restricting the calculation to Opportunities whose Stage represents Closed Won. Option C would incorrectly include open and lost Opportunities. COUNT-based options calculate the number of records rather than total sales value, and the roll-up belongs on the Account because that is where the summarized result must appear. Salesforce ' s current documentation specifically gives the example of an Account roll-up displaying total Opportunity amount and filtering the aggregation to only won Opportunities.

================

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

In Lightning App Builder, Salesforce provides a standard Chatter component for record pages. 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 related list component does not add the Chatter feed.

B is incorrect because the standard Chatter component is available in Lightning App Builder; it does not need to come from AppExchange.

D is incorrect because a custom component is unnecessary when Salesforce provides the standard Chatter component.
