NEW QUESTION # 26
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 trigger is a a helper class.
- B. The trigger is getting executed multiple times.
- C. The trigger does not have sufficient code coverage.
- D. The developer does not have the correct user permission.
Answer: B
Explanation:
The correct answer is that the trigger is getting executed multiple times. This error message indicates that the trigger has exceeded the maximum number of recursions allowed by Salesforce, which is 16. This can happen when the trigger causes an update on the same object or a related object, which in turn fires the trigger again, creating an infinite loop. To avoid this, the developer should use a static variable to control the trigger execution and prevent it from running more than once in the same transaction.

NEW QUESTION # 37
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.
Answer: C
Explanation:
To improve runtime performance of Apex calls by caching result on the client, the most efficient way to implement this and follow best practices is to decorate the server-side method with @AuraEnabled (cacheable=true). This annotation enables the method to be called from a Lightning web component and also caches the method results on the client. This reduces the number of server requests and improves the responsiveness of the component. The cacheable attribute can only be set to true for methods that are read-only and don't change any data. The other options are not correct because:
* Decorating the server-side method with @AuraEnabled (total=true) does not cache the result on the client, but rather indicates that the method returns the total number of records that match a query.
* Calling the setStorable() method on the action in the JavaScript client-side code is a deprecated way of caching the result on the client for Aura components, not Lightning web components. It also requires more code than using the cacheable attribute.
* Setting a cookie in the browser for use upon return to the page is not a reliable way of caching the result on the client, as cookies can be deleted, expired, or blocked by the browser. It also does not leverage the built-in caching mechanism of the Lightning platform. References:

NEW QUESTION # 39
Which three operations affect the number of times a trigger can fire?
Choose 3 answers
- A. Criteria-based Sharing calculations
- B. Process Flows
- C. Workflow Rules
- D. Email messages
- E. Roll-Up Summary fields
Answer: B,C,E
Explanation:
The number of times a trigger can fire depends on the number of records that are processed and the number of DML operations that are performed. Some operations can cause the trigger to fire multiple times, either by updating the same records or by updating related records. These operations include:
* Process Flows: A process flow is a declarative tool that can automate complex business processes by executing actions based on criteria. A process flow can update the same record that triggered it, or a related record, which can cause the trigger to fire again1.
* Workflow Rules: A workflow rule is a declarative tool that can automate tasks and field updates based on criteria. A workflow rule can update the same record that triggered it, or a related record, which can cause the trigger to fire again2.
* Roll-Up Summary fields: A roll-up summary field is a custom field that aggregates child record information into a parent record. A roll-up summary field can update the parent record when a child record is inserted, updated, deleted, or undeleted, which can cause the trigger to fire again3.
The other options do not affect the number of times a trigger can fire. Criteria-based sharing calculations and email messages do not update records or cause DML operations. References:
