Welcome to your Platform Developer 2

A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for certain geographic regions. When a contact is inserted, the default information should be set on the contact from the custom metadata records based on the contact's address information. Additionally, if a user attempts to delete a contact that belongs to a flagged region, the user must get an error message. Depending on company personnel resources, what are two ways to automate this? Choose 2 answers

Remote action

Flow Builder

Apex trigger

Apex invocable method

A company has many different unit test methods that create Account records as part of their data setup. A new required field was added to the Account and now all of the unit tests fail. What is the optimal way for a developer to fix the issue?

Add a before insert trigger on Account to set the value of the required field,

Change the required field to be a validation rule that excludes the System Administrator profile.

An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature. The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters. What is the optimal way to implement these requirements?

Write a Validation Rule on the Contact for the Is Primary logic and a before update trigger on Contact for the last name logic.

Write an after update trigger on Contact for the Is Primary logic and a separate before update trigger on Contact for the last name logic.

Write a single trigger on Contact for both after update and before update and callout to helper classes to handle each set of logic.

Write an after update trigger on Account for the Is Primary logic and a before update trigger on Contact for the last name logic.

Users report that a button on a custom Lightning web component (LWC) is not saving the data they enter. The button looks to be clicked, but the LWC simply sits there, seemingly doing nothing. What should the developer use to ensure error messages are properly displayed?

Add a try-catch block surrounding the DML statement.

Use the Database method with a110rNone Set to false.

Add the tag to the component.

Add JavaScript and HTML to display an error message.

developer is inserting, updating, and deleting multiple lists of records in a single transaction and wants to ensure that any error prevents all execution. How should the developer implement error exception handling in their code to handle this?

Use Database methods to obtain lists of Database.SaveResults.

Use a try-catch statement and handle DML cleanup in the catch statement,

Use Database.setSavepoint {} and Database.rollBack with a try-catch statement.

Use a try-catch and use sObject.addError() on any failures.

Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing. What is the recommended best solution to accomplish this?

PushTopic event

Qutbound message

Trigger with HTTP callout

Platform event

An Apex trigger creates an order co record every time an Opportunity is won by a Sales Rep. Recently the trigger is creating two orders. What is the optimal technique for 2 developer to troubleshoot this?

Disable all flows, and then re-enable them one at at time to see which one causes the error.

Run the Apex Test Classes for the Apex trigger to ensure the code still has sufficient code coverage.

Set up debug logging for every Sales Rep, then monitor the logs for errors and exceptions,

Add system.debug() statements to the code and use the Developer Console logs to trace the code.

A developer needs to store variables to control the style and behavior of a Lightning Web Component. Which feature can be used to ensure that the variables are testable in both Production and all Sandboxes?

Custom setting

Custom object

Custom variable

Custom metadata

What should a developer use to query all Account fields for the Acme account in their sandbox?

SELECT FIELDS FAOM Account WHERE Name = ‘Acme’ LIMIT 1

SELECT FIELDS (ALL) FROM Account WHERE Name = ‘Acme’ LIMIT 1

SELECT ALL FROM Account WHERE Name = “Acme’ LIMIT 1

SELECT * FROM Recount WHERE Names = ‘Aeme’ LIMIT

An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed and Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance. When a test batch of records are loaded, the Apex trigger creates Contract records. A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created. 'What is the most extendable way to update the Apex trigger to accomplish this?

Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.

Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.

Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.

Use a list custom setting ta disable the trigger for the user who loads the data.

An org has an existing process, built using Process Builder, on Opportunity that sets a custom field, CommissionBaseAmount__c, when an Opportunity is edited and the Opportunity's Amount changes. A developer recently deployed an Opportunity before update trigger that uses the CommissionBaseAmount__c and complex logic to calculate a value for a custom field, CommissionAmount__c, when an Opportunity stage changes to Closed/Won. Users report that when they change the Opportunity to Closed/Won and also change the Amount during the same save, the CommissionAmount__c is incorrect. Which action should the developer take to correct this problem?

A Replace the process with a Fast Field Update record-trigger flow.

Call the trigger from the process.

Call the process from the trigger.

A developer writes a Lightning web component that displays a dropdown list of all custom objects in the org from which a user will select. An Apex method prepares and returns data to the component. What should the developer do to determine which objects to include in the response?

Check the isCustom() value on the sObject describe result,

Import the list of all custom objects from @salesforce/schema.

Check the getobiectType [) value for ‘Custom’ or “Standard’ on the sObject describe result.

Use the getcustomobjects() method from the Schema class.

A developer is asked to look into an issue where a scheduled Apex is running into DML limits. Upon investigation, the developer finds that the number of records processed by the scheduled Apex has recently increased to more than 10,000.What should the developer do to eliminate the limit exception error?

Use the @future annotation.

Implement the Qususabls interface.

Implement the Batchable interface.

Use platform events.

A developer is tasked with ensuring that email addresses entered into the system for Contacts and for a custom object called survey Response c do not belong to a list of blocked domains. The list of blocked domains is stored in a custom object for ease of maintenance by users. The survey Response c object is populated via a custom Visualforce page. What is the optimal way to implement this?

Implement the logic in validation rules on the Contact and the Burvey Response_c Objects.

Implement the logic in a helper class that is called by an Apex trigger on Contact and from the custom Visualforce page controller.

Implement the logic in an Apex trigger on Contact and also implement the logic within the custom Visualforce page controller.

Implement the logic in the custom Visualforce page controller and call “that method from an Apex trigger on Contact.

Which tag should a developer use to display different text while an is Processing an action?

<apex:actionSupparts

<apex:pageMes sagas

A developer used custom settings to store some configuration data that changes occasionally. However, tests are now Failing in some of the sandboxes that were recently refreshed. What should be done to eliminate this issue going forward?

Set the setting type on the custom setting to List.

Replace custom settings with static resources.

Set the setting type on the custom setting to Hierarchy.

Replace custom settings with custom metadata.

A developer has a Visualforce page that automatically assigns ewnership of an Account to a queue upon save. The page appears to correctly assign ownership, but an assertion validating the correct ownership fails. What can cause this problem?

The test class does not use the Bulk API for loading test data.

The test class does not use the seeallData=true= annotation.

The test class does not implement the Queueable interface.

Universal Containers develops a Salesforce application that requires frequent interaction with an external REST API. To avoid duplicating code and improve maintainability, how should they implement the APL integration for code reuse?

Use a separate Apex class for each API endpoint to encapsulate the integration logic,

Include the API integration code directly in each Apex class that requires it.

Create a reusable Apex class for the AFL integration and invoke it from the relevant Apex classes.
