Salesforce Platform Developer I (PDI) Sample Questions (Q73-Q78):NEW QUESTION # 73
A developer identifies the following triggers on the Expense _c object:

The triggers process before delete, before insert, and before update events respectively.
Which two techniques should the developer implement to ensure trigger best practices are followed?
Choose 2 answers
  • A. Maintain all three triggers on the Expense __c object, but move the Apex logic out of the trigger definition.
  • B. Create helper classes to execute the appropriate logic when a record is saved.
  • C. Unify the before insert and before update triggers and use Flow for the delete action.
  • D. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
Answer: B,D
Explanation:
* A. Unify all three triggers in a single trigger on the Expense__c object that includes all events:
* Salesforce best practices recommend having only one trigger per object to avoid redundancy and conflicts.
* By combining all the events (before delete, before insert, and before update) into a single trigger, the developer can manage the logic in an organized and maintainable manner.
* This also simplifies debugging and ensures that the trigger logic executes in a predictable order.
* C. Create helper classes to execute the appropriate logic when a record is saved:
* Using helper classes allows for a clean separation of concerns. The trigger becomes a dispatcher that delegates logic to dedicated classes.
* For example, you can create methods like applyDefaultsToExpense(), validateExpenseUpdate(), and deleteExpense() in a helper class and invoke them from the trigger.
* This improves reusability, readability, and testability of the code.
Why not the other options?
* B. Unify the before insert and before update triggers and use Flow for the delete action:
* While Flow is a powerful tool, it is not ideal for deleting records or replacing Apex trigger functionality, especially when triggers already exist for other events.
* D. Maintain all three triggers on the Expense__c object but move the Apex logic out of the trigger definition:
* Maintaining multiple triggers on the same object can lead to conflicts and execution order issues, even if the logic is moved to helper classes.

NEW QUESTION # 74
A developer wants to improve runtime performance of Apex calls by caching results on the client.
What is the most efficient way to implement this and follow best practices?
  • A. Set a cookie in the browser for use upon return to the page.
  • B. Decorate the server-side method with @AuraEnsbled(storable=true).
  • C. Call the setStorable () method on the action in the JavaScript client-side code.
  • D. Decorate the server-side method with @AuraZnabled(cacheable=true).
Answer: D
Explanation:
To improve runtime performance by caching Apex call results on the client, the developer should decorate the server-side method with @AuraEnabled(cacheable=true).
@AuraEnabled(cacheable=true) Annotation:
When applied to an Apex method, it enables the method's results to be cached on the client, improving performance for subsequent calls.
This is especially effective in Lightning Web Components (LWC) and can also be used in Aura components.
"To cache method results, annotate the method with @AuraEnabled(cacheable=true). Methods annotated with cacheable=true are called cached methods."
- Lightning Web Components Developer Guide: Call Apex Methods
Why Not Other Options:
A . Call the setStorable() method on the action in the JavaScript client-side code: This approach is used in Aura components but is less efficient and not considered best practice compared to using cacheable=true.
"For improved performance, use @AuraEnabled(cacheable=true) instead of action.setStorable()."
- Aura Components Developer Guide: Calling Server-Side Actions
B . Set a cookie in the browser for use upon return to the page: Managing cookies for caching Apex results is not efficient and can lead to security and scalability issues.
C . Decorate the server-side method with @AuraEnabled(storable=true): There is no storable=true parameter for @AuraEnabled. The correct parameter is cacheable=true.
Best Practices:
Use @AuraEnabled(cacheable=true): This is the recommended way to cache Apex method results in Lightning components.
"Apex methods annotated with @AuraEnabled(cacheable=true) are cached on the client and shared across components."
- Lightning Web Components Developer Guide: Apex Methods Cache
Conclusion: By decorating the Apex method with @AuraEnabled(cacheable=true), the developer enables client-side caching of the method's results, improving runtime performance in an efficient and recommended way.

NEW QUESTION # 75
An Opportunity needs to have an amount rolled up from a custom object that is not in a master-detail relationship.
How can this be achieved?
  • A. Write a trigger on the Opportunity object and use tree sorting to sum the amount for all related child objects under the Opportunity.
  • B. Use the Streaming API to create real-time roll-up summaries.
  • C. Write a trigger on the child object and use an aggregate function to sum the amount for all related child objects under the Opportunity.
  • D. Use the Metadata API to create real-time roll-up summaries.
Answer: C
Explanation:
Why a Trigger on the Child Object?
Since the relationship is not master-detail, a trigger on the child object can perform aggregate calculations and update the parent Opportunity.
Why Not Other Options?
A: Tree sorting is unnecessary and unrelated to roll-up summaries.
B and D: Neither Streaming API nor Metadata API is suitable for real-time roll-up calculations.
