Salesforce PDI Online Questions & Answers

• Question 201:

  What is a considerations for running a flow in debug mode?

  A. When debugging a schedule-triggered flow, the flow starts only for one record.
  B. Clicking Pause allows an element to be replaced in the flow.
  C. DML operations will be rolled back when the debugging ends.
  D. Callouts to external are not when debugging a flow.
  C. DML operations will be rolled back when the debugging ends.

  ---

  Explanation

  When a flow runs in debug mode, Salesforce performs a rollback at the end of the debug session, so any DML changes made during debugging are not committed to the database. The other options are incorrect because debug mode does not replace elements, does not universally block callouts, and scheduled flows are simulated rather than restricted to a single record by default.

• Question 202:

  A developer wants to improve runtime performance of Apex calls by caching result on the client.

  What is the most efficient way to implement this and follow best practices?

  A. Decorate the server-side method with @AuraEnabled (total-true).
  B. Call the setStoeable () method on the action in the javaScript client-sidecode.
  C. Decorate the server-side method with @AuraEnabled (cacheable-true.
  D. Set a ciikie in the browser for use upon return to the page.
  C. Decorate the server-side method with @AuraEnabled (cacheable-true.

• Question 203:

  Which two scenarios require an Apex method to be called imperatively from a Lightning web component? Choose 2 answer

  A. Calling a method that makes a web service callout
  B. Calling a method that is not annotated with cacheable-true
  C. Calling a method with the click of a button
  D. Calling a method that is external to the main controller for the Lightning web component
  B. Calling a method that is not annotated with cacheable-true
  D. Calling a method that is external to the main controller for the Lightning web component

• Question 204:

  If Apex code executes inside the execute() method of an Apex class when implementing the Batchable interface, which two statements are true regarding governor limits? Choose 2 answers

  A. The Apex governor limits are reset for each iteration of the execute () method.
  B. The Apex governor limits cannot be exceeded due to the asynchronaus nature of the transaction.
  C. The Apex governor limits will use the asynchronous limit levels.
  D. The Apex governor limits are omitted while calling the constructor of the Apex class.
  A. The Apex governor limits are reset for each iteration of the execute () method.
  C. The Apex governor limits will use the asynchronous limit levels.

  ---

  Explanation

  Option A: Governor limits are reset for each execution of the execute() method in a batch job because each batch is treated as a separate transaction.

  Option C: Batch jobs use asynchronous governor limits, which are higher than synchronous limits.

• Question 205:

  A developer wrote the following two classes:

  

  The StatusFetcher class successfully compiled and saved. However, the Calculator class has a compile time error.

  How should the developer fix this code?

  A. Change the class declaration for the statusFetcher class to public with inherited sharing.
  B. Make the is Active method in the StatusFetcher class public.
  C. Make the doCalculations method in the Calculation class private.
  D. Change the class declaration for the Calculator class to public with inherited sharing.
  B. Make the is Active method in the StatusFetcher class public.

• Question 206:

  Developers at Universal Containers (UC) use version control to share their code changes, but they notice that when they deploy their code to different environments they often have failures. They decide to set up Continuous Integration (CI).

  What should the UC development team use to automatically run tests as part of their CI process?

  A. Salesforce CLI
  B. Visual Studio Code
  C. Force.com Toolkit
  D. Developer Console
  A. Salesforce CLI

  ---

  Explanation

  Why Salesforce CLI?

  The Salesforce CLI supports scripting for Continuous Integration (CI) pipelines, allowing automatic testing and deployment as part of the CI process.

  Why Not Other Options?

  B: Visual Studio Code is a development IDE, not a CI tool.

  C: Force.com Toolkit is outdated and does not support CI processes.

  D: Developer Console is for debugging and manual testing, not automation.

• Question 207:

  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 logs to identify the source of the issue.
  B. Add system.debug statements to the code to track the execution flow and identify the issue.
  C. Use the Apex Interactive Debugger to step through the code and identify the issue.
  D. Disable the trigger in production and test to see if the issue still occurs.
  C. Use the Apex Interactive Debugger to step through the code and identify the issue.

  ---

  Explanation

  The Apex Interactive Debugger allows a developer to step through trigger execution line by line, inspect variable values, and observe execution context in real time, which is the most effective way to identify the root cause of record duplication. System.debug statements are less precise and harder to correlate, historical event logs are not designed for code-level debugging, and disabling the trigger in production is not an appropriate or safe troubleshooting approach.

• Question 208:

  A developer wants to prevent recursive trigger execution within a single transaction.

  What is the best practice?

  A. Disable the trigger temporarily
  B. Use a static Boolean variable
  C. Use a custom metadata type
  D. Use an after trigger only
  B. Use a static Boolean variable

  ---

  Explanation

  Recursive trigger execution can occur when a trigger performs DML operations that cause the same trigger to fire again. The standard best practice to prevent this behavior is to use a static Boolean variable in a helper class. Static variables persist for the duration of the transaction and can be used as flags to ensure the trigger logic executes only once per transaction. Disabling triggers or relying on trigger context alone is not reliable, and custom metadata is not transaction-scoped, making it unsuitable for recursion control.

• Question 209:

  Universal Containers has created a unique process for tracking container repairs. A custom field, status_c, has been created within the container_c custom object. A developer is tasked with sending notifications to multiple external systems every time the value of the status_picklist changes.

  Which two tools should the developer use to meet the business requirement and ensure low maintenance of the solution? Choose 2 answers

  A. Record-Triggered flow
  B. Apex trigger
  C. Apex callouts
  D. Platform event
  C. Apex callouts
  D. Platform event

• Question 210:

  Refer to the following Apex code:

  

  What is the value of ?when it is written to the debug log?

  B. 1
  C. 2
  D. 3
  C. 2

  ---

  Explanation

  Execution Flow :

  Initially, x = 0.

  Inside the do block:

  x = 1 is set.

  x++ increments x to 2.

  The condition x < 1 is evaluated. Since x = 2, the condition is false, and the loop exits.

  Value of x in Debug Log :

  Final value of x after the loop is 2.
