NEW QUESTION # 41
A developer at AW Computing is tasked to create the supporting test class for programmatic customization that leverages records stored within the custom object, Pricing_Structure__c. AW Computing has a complex pricing structure for each item on the store, spanning more than 500 records, Which two approaches can the developer use to ensure Pricing Strucrture_c records are available when the test class is executed?
Choose 2 answers
Answer: C,D
Explanation:
To ensure Pricing_Structure__c records are available when the test class is executed, the developer can use the following approaches:
Option A: Use a Test Data Factory class.
Valid Approach.
A Test Data Factory class is a utility class that creates test data for use in test methods.
It helps in generating consistent test data and promotes reusability.
The factory class can create the necessary Pricing_Structure__c records for testing.
Test.loadData() allows loading test data from a static resource (CSV file) into test methods.
This is useful for loading large datasets, such as over 500 records.
The CSV file can contain the Pricing_Structure__c records needed for testing.
Using SeeAllData=true accesses existing org data, which is not recommended due to test data isolation.
Tests should create their own data to ensure reliability and avoid dependencies on org data.
The without sharing keyword affects record sharing and visibility, not data availability in tests.
It does not help in creating or accessing test data.
Reference:

Best Practices for Test Classes
Option B: Use the Test.loadData() method.
Valid Approach.
Test.loadData Method
Using Test.loadData()
Incorrect Options:
Option C: Use the @IsTest(SeeAllData=true) annotation.
Not Recommended.
Isolation of Test Data from Organization Data in Unit Tests
Option D: Use without sharing on the class declaration.
Irrelevant.
Using the with sharing or without sharing Keywords
Conclusion:
To ensure Pricing_Structure__c records are available in tests, the developer can use Option A (Test Data Factory) and Option B (Test.loadData()).
NEW QUESTION # 42
A developer has the following requirements:
Calculate the total amount on an Order.
Calculate the line amount for each Line Item based on quantity selected and price.
Move Line Items to a different Order if a Line Item Is not In stock.
Which relationship implementation supports these requirements on its own?
Answer: B
Explanation:
To meet the given requirements, we need a relationship that allows:
Calculating the total amount on an Order.
This can be achieved using roll-up summary fields on the Order object to sum up values from its Line Item child records.
Roll-up summary fields are only available on the master object in a master-detail relationship.
Reference:
Calculating the line amount for each Line Item based on quantity selected and price.
This calculation can be handled using formula fields or triggers on the Line Item object.
Moving Line Items to a different Order if a Line Item is not in stock.
This requires the ability to reparent the Line Item to a different Order.
In a master-detail relationship, you can enable reparenting by selecting "Allow reparenting" in the relationship field settings.
Given these considerations, the appropriate relationship is:
Line Item has a re-parentable master-detail field to Order.
Option D satisfies all the requirements:
Master-detail relationship allows roll-up summary fields on Order.
Reparenting is enabled, allowing Line Items to be moved to a different Order.
Line Item calculations can be handled on the child object.
Incorrect Options:
Option A & C: Lookup relationships do not support roll-up summary fields.
Option B: If the Order has a master-detail field to Line Item, it contradicts the natural parent-child relationship.
Conclusion:
Option D is the correct choice as it supports roll-up summary fields, allows reparenting, and aligns with the parent-child relationship needed.
NEW QUESTION # 43
A developer is creating anapplication to track engines and their parts. An individual part can be used in different types of engines. What data model should be used to track the data and to prevent orphan records?
Answer: B
NEW QUESTION # 44
What should a developer use to script the deployment and unit test execution as part of continuous integration?
Answer: D
Explanation:
Salesforce CLI allows developers to automate deployments and run unit tests as part of a continuous integration (CI) pipeline. It is the most efficient tool for scripting these processes.
Reference:Salesforce CLI
Incorrect Options:
A:VS Code is an IDE and requires CLI integration for scripting.
B:Execute Anonymous is used for running code snippets manually, not for CI.
D:Developer Console is for manual testing and debugging, not CI automation.
Below is the formatted response for the provided question, adhering to the specified format and requirements.
The answer is based on official Salesforce Platform Developer I documentation, focusing on the Data Modeling and Management topic. The response includes a comprehensive explanation, corrects any potential errors, and references relevant Salesforce documentation.
NEW QUESTION # 45
Which two scenarios require an Apex method to be called imperatively from a Lightning web component?
Choose 2 answer
Answer: A,D
Explanation:
The two scenarios that require an Apex method to be called imperatively from a Lightning web component are:
* Calling a method that makes a web service callout: A web service callout is a request that is sent from Salesforce to an external service, such as a REST or SOAP API1. Web service callouts are subject to limits and restrictions, such as the maximum number of callouts per transaction, the maximum response size, and the requirement to use asynchronous execution for long-running callouts1. Therefore, to control when the callout occurs and handle the response or errors, it is recommended to call the Apex method that makes the callout imperatively from the Lightning web component2.
* Calling a method that is not annotated with cacheable=true: The cacheable=true annotation on an Apex method indicates that the method can be cached and reused by the Lightning Data Service, which is a layer of the Lightning web component framework that manages data and metadata3. This annotation improves the performance and user experience of the Lightning web component, as it reduces the number of server round trips and network latency3. However, not all Apex methods can or should be annotated with cacheable=true, such as methods that perform DML operations, return different results for different users, or depend on the current state of the database3. In such cases, the Apex method should be called imperatively from the Lightning web component to ensure the data is fresh and consistent2.
