Question 1

A developer wants to import 500 Opportunity records into a sandbox.

Why should the developer choose to use Data Loader instead of Data Import Wizard?

AData Loader automatically relates Opportunities to Accounts.

BData Loader runs from the developer's browser.

CData Import Wizard does not support Opportunities.

DData Import Wizard can not import all 500 records,

Answer : C

Question 2

A developer needs to create a baseline set of data (Accounts, Contacts, Products, Assets) for an entire suite of Apex tests allowing

them to test isolated requirements for various types of Salesforce cases.

Which approach can efficiently generate the required data for each unit test?

ACreate a mock using the HttpcalloutMock interface.

BUse @TestSetup with a void method.

CAdd @IsTest (seeAllData=true) at the start of the unit test class.

DCreate test data before Test .startTest() in the unit test.

Answer : B

Question 3

A Primaryld_c custom field exists on the Candidate _c custom object. The field is used to store each candidate's id number and is marked as Unique in the schema definition.

As part of a data enrichment process, Universal Containers has a CSV file that contains updated data for all candidates in the system. The file contains each Candidate's primary .. as a data point. Universal Containers wants to upload this information into Salesforce, while ensuring all data rows are correctly mapped to a candidate in the system.

Which technique should the developer implement to streamline the data upload?

AUpload the CSV into-a custom object related to candidate__c.

BCreate a before insert trigger to correctly map the records,

CUpdate the Primarytd_c field definition to mark it. as.an External Id.

DCreate a before save flow to correctly map the records.

Answer : C

C . Update the PrimaryId__c field definition to mark it as an External Id:

Marking PrimaryId__c as an External Id allows Salesforce to use this field to match records during the data import process, streamlining the process of mapping CSV rows to existing Candidate__c records.

External Id fields are indexed and can be used in tools like Data Loader, Data Import Wizard, or API-based upserts to ensure that records are matched correctly based on the value of the external ID field.

In this case, since PrimaryId__c is unique, marking it as an external ID eliminates the need for custom triggers or flows.

Why this is the best solution?

This technique leverages built-in Salesforce capabilities (no need for custom code or automation).

It ensures accurate record matching and is the standard approach for data enrichment tasks involving unique identifiers.

Why not the other options?

A . Upload the CSV into a custom object related to Candidate__c:

This approach unnecessarily introduces another object, adding complexity. The goal is to update existing Candidate__c records, not store the data in a separate object.

B . Create a before insert trigger to correctly map the records:

Using triggers for this purpose is overengineering. Salesforce already provides tools like upsert for this exact use case. Writing a trigger would require additional effort and could introduce unintended errors or performance issues.

D . Create a before save flow to correctly map the records:

While flows are powerful, they are not the optimal solution for this use case. Data mapping is better handled using an external ID during import to ensure proper matching and updates.

Question 4

Which code statement includes an Apex method named updateAccounts in the class AccountController for use in a Lightning web component?

Aimport updateAccounts from 'AccountControlles';

Bimport updateAccounts from 'Salesforce/apex/AccountController:';

Cimport updateAccounts from 'Account@ontroller.updateAccounts';

Dimport updateAccounts from '@salesforce/apex/AccountController.updateAccounts';

Answer : B

Question 5

Universal Containers is building a recruiting app with an Applicant object that stores information about an individual person and a Job

object that represents a job. Each applicant may apply for more than one job.

What should a developer implement to represent that an applicant has applied for a job?

AJunction object between Applicant and Job

BLookup field from Applicant to Job

CMaster-detail field from Applicant to Job

DFormula field on Applicant that references Job

Answer : A

A . Junction object between Applicant and Job:

Since an Applicant can apply for multiple Jobs and each Job can have multiple Applicants, this is a many-to-many relationship.

Salesforce requires a junction object to represent many-to-many relationships. The junction object will have two master-detail relationships: one to the Applicant object and one to the Job object.

The junction object could be named something like JobApplication__c, which would represent the specific instance of an applicant applying for a particular job.

Why this is the correct approach?

A junction object allows for robust data management and reporting capabilities in a many-to-many relationship.

This design ensures that each combination of applicant and job is captured as a unique record in the JobApplication__c junction object.

It also allows storing additional details about the application, such as application date, status, and feedback.

Why not the other options?

B . Lookup field from Applicant to Job:

A lookup field creates a one-to-many relationship. While an Applicant could reference one Job, it does not support the many-to-many relationship required in this scenario.

C . Master-detail field from Applicant to Job:

A master-detail relationship is a one-to-many relationship, which is unsuitable for a many-to-many relationship. Additionally, you cannot have two master-detail fields on a single object to connect Applicant and Job directly.

D . Formula field on Applicant that references Job:

A formula field cannot establish relationships between records or represent a many-to-many relationship. It is only for computed fields.
