NEW QUESTION # 69
A developer is asked to build a solution that will automatically send an email to the customer when an Opportunity stage changes. The solution must scale to allow for 10,000 emails per day. The criteria to send the email should be evaluated after certain conditions are met.
What is the optimal way to accomplish this?
Answer: C
Explanation:
Using an Email Alert with Flow Builder allows for scalable solutions that can handle large volumes of emails, and it offloads the processing from Apex to Salesforce's declarative automation tools. This approach is also bulk-safe, as it does not rely on Apex code that could hit governor limits.
NEW QUESTION # 70
Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer: A
Explanation:
Platform events provide a robust and scalable way to communicate changes and events from Salesforce to external systems, especially when there is no requirement for Salesforce to wait for a response. They are designed to support event-driven architectures and can handle high volumes of events that can be published and consumed by external systems. Outbound messages, on the other hand, are limited by the need for an acknowledgment response from the target system, which can introduce latency.
NEW QUESTION # 71

NEW QUESTION # 73
Consider the below trigger intended to assign the Account to the manager of the Account's region:
Which two changes should a developer make in this trigger to adhere to best practices? Choose 2 answers A)
B)
C)
D)
Answer: B,C
Explanation:
The best practices for writing triggers in Salesforce include bulkifying your code to handle multiple records efficiently and reducing the number of SOQL queries, especially within loops, to avoid hitting governor limits.
Option B is correct because moving the SOQL query outside of the for loop is essential to bulkify the trigger. Performing a query within a loop can cause a SOQL governor limit to be reached if the trigger is processing many records. The best practice is to collect all necessary data before the loop starts and then process it within the loop.
Option C is correct as well, because using a Map to cache the results of a SOQL query by Id is another way to bulkify the code. This allows you to query all the necessary data once and then access it efficiently in memory, avoiding repeated queries.
Option A is incorrect because adding isExecuting before the update doesn't address any best practices related to bulkification or SOQL query optimization.
Option D is incorrect because the last line should not be removed if the developer intends to perform DML on the accountList. However, this line should be outside of the loop and is unnecessary if the trigger context is 'before insert' or 'before update', since in those contexts, changes to records in Trigger.new are implicitly saved without the need for explicit DML.
