Salesforce Platform Developer II Sample Questions (Q26-Q31):

NEW QUESTION # 26
A developer has a requirement to query three fields (Id, Name, Type) from an Account; and first and last names for all Contacts associated with the Account.
Which option is the preferred, optimized method to achieve this for the Account named 'Ozone Electronics'?

Answer: C

NEW QUESTION # 27
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?

A. Write an after update trigger on Contact for the Is Primary logic and a separate before update trigger on Contact for the last name logic.
B. Write a Validation Rule on the Contact for the Is Primary logic and a before update trigger on Contact for the last name logic.
C. Write a single trigger on Contact for both after update and before update and callout to helper classes to handle each set of logic.
D. Write an after update trigger on Account for the Is Primary logic and a before update trigger on Contact for the last name logic.

Answer: C

Explanation:
The optimal way to implement these requirements is to write a single trigger on Contact for both after update and before update and call out to helper classes to handle each set of logic. A trigger is a piece of Apex code that executes before or after specific data manipulation language (DML) events occur, such as inserting, updating, or deleting records. A trigger can handle both before and after events in the same code block by using trigger context variables to determine the event type. A helper class is a class that contains reusable methods that can be invoked by a trigger or another class. A helper class can encapsulate the logic for normalizing the address and converting the last name to uppercase, and be called by the trigger based on the event type. This way, the developer can avoid code duplication, improve readability, and adhere to the best practices for writing triggers34.

NEW QUESTION # 28
A company requires an external system to be notified whenever an account is updated.
trigger AccountTrigger on Account (after update){ for (Account
updatedAccount:Trigger.new){ AccountTriggerHelper.notinyxternalSystem
(updatedAccount.id); } } public class AccountTriggerHelperfuture(callout=true)
{ public static void notinyxternalSystem(Id accountId){ Account acc = [Select id, name from Account where accountId = :accountId]; http objectHttp h = new Http(); HttpRequest req = new HttpRequest(); req.setEndpoint('http://example.org/ restService'); req.setMethod('POST'); req.setBody(JSON.serialize(acc)); HttpResponse res = h.send(req); } } What LimitException could the following code trigger?

A. System.LimitException: Too many future calls
B. System.LimitException: Too many callouts
C. System.CalloutException: Callout from triggers are currently not supported
D. System.LimitException: Too many SOQL queries

Answer: A

NEW QUESTION # 29
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?

A. Write an after update trigger on Contact for the Is Primary logic and a separate before update trigger on Contact for the last name logic.
B. Write a Validation Rule on the Contact for the Is Primary logic and a before update trigger on Contact for the last name logic.
C. Write a single trigger on Contact for both after update and before update and callout to helper classes to handle each set of logic.
D. Write an after update trigger on Account for the Is Primary logic and a before update trigger on Contact for the last name logic.

Answer: C

Explanation:
A single trigger on Contact that handles both after update and before update events, utilizing helper classes for each logic set, is the most optimal implementation. It centralizes the logic for maintaining primary contacts and normalizing last names while allowing for clear separation of concerns through helper classes.References:
