Question # 10

Universal Containers (UC) processes orders in Salesforce in a custom object, ord=xr <. They also allow sales reps to upload CSV files with thousands of orders at a time.

A developer is tasked with integrating orders placed in Salesforce with UCâ€™s enterprise resource planning (ERP) system.

After the status for an order__ c is first set to 'Placedâ€™, the order information must be sent to a REST endpoint in the ERP system that can process one order at a time.

What should the developer implement to accomplish this?

Callout from an Qfuture method called from a trigger

Callout from a Batchable class called from a scheduled job

Flow with a callout from an invocable method

Callout from a Queueable class called from a trigger

Full Access

Answer:

Explanation:

To integrate Order__c records with the ERP system after their status is set to 'Placed', and considering that orders may be uploaded in bulk, the developer should:

Option D: Callout from a Queueable class called from a trigger

Explanation:

Trigger: Implement an after-update trigger on Order__c to detect when the status changes to 'Placed'.

Queueable Apex: Use Queueable Apex to handle asynchronous processing and callouts. Queueable classes support callouts by implementing the Database.AllowsCallouts interface.

Benefits:

Handles Bulk Data: Queueable Apex can process records in batches and can be chained for processing large volumes.

Supports Callouts: Unlike future methods, Queueable Apex allows for more complex data types and supports callouts with fewer limitations.

[:, "To make a Web service callout to an external service or API, you must use asynchronous Apex, such as future methods, Queueable Apex, or batch Apex.", "Queueable Apex is an asynchronous Apex feature that is a superset of future methods with some extra features."â€” Apex Developer Guide: Queueable Apex, Why Other Options Are Incorrect:, Option A: Callout from an @future method called from a trigger, @future methods have limitations, such as accepting only primitive types as parameters and a limit of 50 calls per transaction, which can be exceeded when processing thousands of records., Reference:, "Methods with the future annotation must be static methods and can only return a void type. The specified parameters must be primitive data types, arrays of primitive data types, or collections of primitive data types."â€” Apex Developer Guide: Future Methods, Option B: Callout from a Batchable class called from a scheduled job, Batch Apex is not immediately triggered by record changes and may not meet the requirement of processing the order after the status changes., Scheduling adds delay and complexity unnecessary for this use case., Option C: Flow with a callout from an invocable method, Flows invoked from triggers (record-triggered flows) cannot perform callouts unless they are configured to run asynchronously, and managing bulk operations with flows can be less efficient., ]

Question # 13

A developer must create a Lightning component that allows users to input Contact record information to create a Contact record, including a Salary__c custom field.

What should the developer use, along with a lightning-record-edit-form, so that salarv < field functions as a currency Input and is only viewable and editable by users that have the correct field level permissions on salary _c?

Question # 15

Which two characteristics are true for Lightning Web Component custom events? Choose 2 answers

Data may be passed in the payload of a custom event using a property called detail.

By default a custom event only propagates to its immediate container and to its immediate child component.

Data may be passed in the payload of a custom event using @wire decorated properties.

By default a custom event only propagates to its immediate container.

Question # 16

A developer needs to have records with specific field values in order to test a new Apex class.

What should the developer do to ensure the data is available to the test?

Use test.loadData() and reference a JSON file in Documents.

Use Test.loadData() and reference a CSV file in a static resource.

Use Anonymous Apex to create the required data.

Use SOQL to query the org for the required data.

Full Access

Answer:

Explanation:

To ensure that specific data is available in test methods, the developer should create test data within the test context.

Option B: Use Test.loadData() and reference a CSV file in a static resource.

Correct Approach.

Explanation:

Test.loadData() is a method that allows test methods to load test data from a CSV file stored as a static resource.

This method creates the records in the test context, ensuring that the data is available during the test execution.

Using a CSV file makes it easy to define multiple records with specific field values.

Usage Example:

@isTest

private class MyTestClass {

@isTest

static void testMethod() {

List testRecords = (List) Test.loadData(MyObject__c.sObjectType, 'MyTestData');

// Proceed with testing using testRecords

}

Where 'MyTestData' is the name of the static resource containing the CSV file.

[Reference:, Test.loadData() Method, Static Resources, Options Not Suitable:, Option A: Use test.loadData() and reference a JSON file in Documents., Incorrect., Explanation:, Test.loadData() does not support loading data from JSON files or from the Documents object., It uses CSV files stored as static resources., Option C: Use Anonymous Apex to create the required data., Not Effective for Testing., Explanation:, Data created via Anonymous Apex is not available in test methods due to data isolation., Test methods operate in their own context and cannot access data created outside the test unless SeeAllData=true is used, which is discouraged., Option D: Use SOQL to query the org for the required data., Not Recommended., Explanation:, Test methods should not rely on existing org data., Tests should create their own data to ensure consistency and avoid dependencies., Using SeeAllData=true is discouraged., Conclusion:, To ensure that records with specific field values are available in the test, the developer should use Test.loadData() with a CSV file stored in a static resource., Therefore, Option B is the correct answer., ]
