NEW QUESTION # 13
Universal Containers recently transitioned from Classic to Lighting Experience. One of its business processes requires certain value from the opportunity object to be sent via HTTP REST callout to its external order management system based on a user-initiated action on the opportunity page. Example values are as follow
* Name
* Amount
* Account
Which two methods should the developer implement to fulfill the business requirement? (Choose 2 answers)
- A. Create a Lightning component that performs the HTTP REST callout, and use a Lightning Action to expose the component on the Opportunity detail page.
- B. Create an after update trigger on the Opportunity object that calls a helper method using
@Future(Callout=true) to perform the HTTP REST callout. - C. Create a Process Builder on the Opportunity object that executes an Apex immediate action to perform the HTTP REST callout whenever the Opportunity is updated.
- D. Create a Visualforce page that performs the HTTP REST callout, and use a Visualforce quick action to expose the component on the Opportunity detail page.
Answer: A,D
Explanation:
The developer should implement either a Lightning component or a Visualforce page that performs the HTTP REST callout, and use a Lightning Action or a Visualforce quick action to expose the component on the Opportunity detail page. These methods allow the developer to create a user interface that can capture the user input and trigger the callout based on a user-initiated action. The Lightning component or the Visualforce page can use the Apex controller to invoke the HTTP callout using the built-in HTTP classes, such as HttpRequest, HttpResponse, and Http. The Lightning Action or the Visualforce quick action can be added to the page layout of the Opportunity object and configured to display the component in a modal dialog or a panel.
Creating a Process Builder or an after update trigger to perform the HTTP REST callout is not a suitable method for this business requirement, because these methods do not provide a user interface or a user-initiated action. The Process Builder or the trigger would execute the callout whenever the Opportunity is updated, regardless of the user input or intention. This could result in unnecessary or unwanted callouts, as well as hitting the governor limits for callouts.

NEW QUESTION # 17
A developer is alerted to an Issue with a custom Apex trigger that is causing records to be duplicated.
What is the most appropriate debugging approach to troubleshoot the issue?
- A. Review the Historical Event legs to identify the source of the issue.
- B. Disable the trigger in production and test to see if the issue still occurs.
- C. Add system.debug statements to the code to track the execution flow and identify the issue.
- D. Use the Apex Interactive Debugger to step through the code and identify the issue.
Answer: C
Explanation:
When a developer is alerted to an issue with a custom Apex trigger causing records to be duplicated, the most appropriate debugging approach is to add System.debug statements to the code.
Option A: Add System.debug statements to the code to track the execution flow and identify the issue Trace Execution Flow: System.debug statements help log the values of variables and the execution path.
Identify Logic Errors: By examining the debug logs, the developer can pinpoint where the duplication is occurring.
Minimal Impact: Adding debug statements is a minimal code change and does not alter the functionality.
Reference:
Debugging with System.debug
Best Practices for Debugging
Why Other Options are Less Optimal or Incorrect:
Option B: Use the Apex Interactive Debugger to step through the code
Limited Availability: The Apex Interactive Debugger is not typically available in production environments.
Requires Setup: Needs special permissions and setup, which may not be feasible.
Option C: Disable the trigger in production and test to see if the issue still occurs Risky: Disabling the trigger can disrupt business processes and data integrity.
Not a Debugging Strategy: Does not help identify the cause within the code.
Option D: Review the Historical Event Logs to identify the source of the issue Insufficient Detail: Event logs may not provide the necessary detail about code execution to identify the issue.
Better for Auditing: More suited for tracking user actions rather than debugging code.
Conclusion:
Adding System.debug statements and reviewing the resulting debug logs is the most appropriate and effective method to troubleshoot and identify the issue causing record duplication.
It allows the developer to understand the code execution flow and make necessary corrections.

NEW QUESTION # 20
A developer created these three Rollup Summary fields in the custom object, Project_ct,
The developer is asked to create a new field that shows the ratio between rejected and approved timesheets for a given project.
Which should the developer use to Implement the business requirement in order to minimize maintenance overhead?
- A. Record-triggered Flow
- B. Formula field
- C. Apex Trigger
- D. Process Builder
Answer: B
Explanation:
In this scenario, a formula field is the most appropriate choice to calculate the ratio between rejected and approved timesheets for a given project. This is because formula fields automatically calculate their values based on other fields' values, requiring no additional maintenance or manual intervention. They are used for read-only purposes and are visible to users if they have read access to the object containing the formula field.
To create the formula field, the developer can use the following expression:
IF(Total_Approved_Timesheets__c > 0, Total_Rejected_Timesheet__c / Total_Approved_Timesheets__c, 0) This expression checks if the total approved timesheets is greater than zero, and if so, divides the total rejected timesheets by the total approved timesheets. Otherwise, it returns zero. This formula field will display the ratio as a decimal number, which can be formatted as a percentage if desired.
References: The use of formula fields for automatic calculations can be referenced in the Salesforce Platform Developer I learning documents, specifically in modules that cover objects and fields management, such as:
* Create Object Relationships
* Data Modeling
* Formula Operators and Functions by Context

NEW QUESTION # 26
A developer Is Integrating with a legacy on-premise SQL database.
What should the developer use to ensure the data being Integrated is matched to the right records in Salesforce?
- A. External ID field
- B. Formula field
- C. External Object
- D. Lookup field
Answer: A
Explanation:
The developer should use an external ID field to ensure the data being integrated is matched to the right records in Salesforce. An external ID field is a custom field that has the External ID attribute, meaning that it contains unique record identifiers from a system outside of Salesforce. When you integrate with an external system, you can use an external ID field to match records based on the external system's ID, rather than the Salesforce ID. This way, you can avoid creating duplicate records or updating the wrong records. An external ID field can also be used as a relationship field to relate records to other objects. A lookup field is a relationship field that allows users to select a record from another object. A formula field is a read-only field that derives its value from a formula expression. An external object is a custom object that maps to data stored outside Salesforce, such as in an external database. These options are not relevant to matching records based on an external system's ID. References:
* Salesforce Help: External ID Fields, page 1
* Trailhead: Platform Developer I Certification Study Guide: Data Modeling, unit 2

- A. Use Lightning Locker Service to enforce sharing rules and field-level security.
- B. Use Lightning Data Service to get the collection of sales records.
- C. Use WITH SECURITY_ENFORCED in the SOQL that fetches the data for the component.
- D. Use Security. stripInaccessible to remove fields inaccessible to the current user.
Answer: D
NEW QUESTION # 29
A custom object Trainer_c has a lookup field to another custom object Gym___c.
Which SOQL query will get the record for the Viridian City gym and it's trainers?
- A. SELECT Id, (SELECT Id FROM Trainer_c) FROM Gym_c WHERE Name - Viridian City Gym'
- B. SELECT Id, (SELECT Id FROM Trainers) FROM Gym_C WHERE Name . Viridian City Gym'
- C. SELECT ID FROM Trainer_c WHERE Gym__r.Name - Viridian City Gym'
- D. SELECT Id, (SELECT Id FROM Trainers) FROM Gym_C WHERE Name - Viridian City Gym'
Answer: A
Explanation:
This SOQL query will get the record for the Viridian City gym and its trainers by using a subquery to fetch the related records from the Trainer_c object. The subquery uses the relationship name Trainer_c, which is the plural form of the custom object name with a suffix of __c. The main query uses the Name field of the Gym_c object to filter by the gym name. The query also uses the correct syntax for SOQL, which requires the use of the equal sign (=) for comparison operators, and single quotes (') for string literals.

NEW QUESTION # 30
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
- A. Use a Test Data Factory class.
- B. Use the @T=Test (SeefAllDaca=rru=) annotation.
- C. Use the Test.loadTesc() method.
- D. Use without sharing on the class declaration.
Answer: A,C
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:
Test Data Factory Pattern
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 # 33
How can a developer check the test coverage of autolaunched Flows before deploying them in a change set?
- A. Use the Flow Properties page.
- B. Use SOQL and the Tooling APL.
- C. Use the Code Coverage Setup page.
- D. Use the ApextestResult class.
Answer: B
Explanation:
As of Winter '20 (API version 47.0), Salesforce introduced the ability to test Autolaunched Flows with test coverage.
However, as of the current knowledge cutoff (2023-09), there is no direct way within the Salesforce UI to check the test coverage of autolaunched flows before deploying them via change sets.
To check the test coverage of flows, developers can use the Tooling API to query for test coverage.
Option A: Use SOQL and the Tooling API.
Correct Answer.
Developers can use the Tooling API to query for Flow test coverage information.
By executing a SOQL query on FlowTestCoverage and FlowVersionView objects via the Tooling API, developers can retrieve coverage data.
This allows checking flow test coverage programmatically before deployment.
The Flow Properties page does not provide test coverage information.
It allows configuring flow settings but not checking test coverage.
Option C: Use the Code Coverage Setup page.
Incorrect.
The Code Coverage page in Setup pertains to Apex code coverage, not Flow coverage.
Option D: Use the ApexTestResult class.
Incorrect.
The ApexTestResult class is used for Apex test results.
It does not provide information on Flow test coverage.
Conclusion:
To check the test coverage of autolaunched Flows before deploying them in a change set, a developer should use SOQL and the Tooling API, which is Option A.
Reference:
Flow Test Coverage with Tooling API
Use Tooling API to Check Flow Coverage
Incorrect Options:
Option B: Use the Flow Properties page.
Incorrect.
