Salesforce Platform Developer I (PDI) Sample Questions (Q50-Q55):

NEW QUESTION # 50
Universal Containers (UC) has an integration with its Accounting system that creates tens of thousands of Orders inside of Salesforce in a nightly batch. UC wants to add automaton that can attempt to match Leads and Contacts to these Orders using the Email Address field on the insert. UC is concerned about the performance of the automation with a large data volume. Which tool should UC use to automate this process?

A. Apex
B. Workflow Rules
C. Process Builder
D. Process Builder with an Autolaunched Flow

Answer: A

NEW QUESTION # 51
How is a controller and extension specified for a custom object named " Notice " on a Visualforce page?

A. < apex:page = " Notice " extends= " myControllerExtension " >
B. < apex:page controller= " Notice_c " extensions= " myControllerExtension " >
C. < apex:page controllers = " Notice, myControllerExtension " >
D. < apex:page standardController= " Notice " extensions= " myControllerExtension " >

Answer: D

Explanation:
Answer A is correct. Visualforce uses pages, standard controllers, custom controllers, and controller extensions to build server-rendered Salesforce UI. Standard controllers provide built-in record operations such as save, while extensions add custom validation, navigation, and business logic. Large result sets require pagination patterns such as StandardSetController to control view state and page load behavior. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint.
For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.

NEW QUESTION # 52
A developer created a trigger on the Account object. While testing the trigger, the developer sees the error message 'Maximum trigger depth exceeded'.
What could be the possible causes?

A. The developer does not have the correct user permission.
B. The trigger does not have sufficient code coverage.
C. The trigger is too long and should be refactored into a helper class.
D. The trigger is getting executed multiple times.

Answer: D

Explanation:
The error message 'Maximum trigger depth exceeded' occurs when a trigger invokes itself recursively more than the allowed limit.
Option C: The trigger is getting executed multiple times.
Correct Answer.
This error indicates that the trigger is recursively calling itself.
This can happen if the trigger performs an update or insert operation that causes the same trigger to fire again, leading to an infinite loop.
Salesforce enforces a limit on the recursion depth to prevent stack overflows.
User permissions do not cause the 'Maximum trigger depth exceeded' error.
Option B: The trigger is too long and should be refactored into a helper class.
*Incorrect, but possible code improvement.
While refactoring code into helper classes is a good practice, it does not directly address the recursion issue causing the error.
Option D: The trigger does not have sufficient code coverage.
Incorrect.
Code coverage issues affect deployment but do not cause runtime errors like 'Maximum trigger depth exceeded'.
Conclusion:
The error is caused because the trigger is getting executed multiple times due to recursion, leading to exceeding the maximum trigger depth.
Reference:
Triggers and Order of Execution
Preventing Recursive Triggers
Incorrect Options:
Option A: The developer does not have the correct user permission.
Incorrect.

NEW QUESTION # 53
A developer must perform a complex SOQL query that joins two objects in a Lightning component.
How can the Lightning component execute the query?

A. Write the query in a custom Lightning web component wrapper and invoke from the Lightning component.
B. Use the Salesforce Streaming APL to perform the SOQL query.
C. Invoke an Apex class with the method annotated as @AuraEnabled to perform the query.
D. Create a flow to execute the query end invoke from the Lightning component.

Answer: C

Explanation:
* The Lightning component cannot directly perform SOQL queries.
* An Apex class annotated with @AuraEnabled provides server-side logic that can execute the SOQL query and return the data to the Lightning component.

NEW QUESTION # 54
Universal Containers (UC) processes orders in Salesforce in a custom object, Order__c. 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 UC's enterprise resource planning (ERP) system.
After the status for an Order__c is first set to 'Placed', 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?

A. Callout from a Batchable class called from a scheduled job
B. Callout from an @future method called from a trigger
C. Callout from a Queueable class called from a trigger
D. Flow with a callout from an invocable method

Answer: C
