NEW QUESTION # 153
developer created this Apex trigger that calls MyClass .myStaticMethod: trigger myTrigger on Contact(before insert) ( MyClass.myStaticMethod(trigger.new, trigger.oldMap); } The developer creates a test class with a test method that calls MyClass.mystaticMethod, resulting in 81% overall code coverage. What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exist?

A. The deployment fails because no assertions were made in the test method.
B. The deployment passes because both classes and the trigger were included in the deployment.

NEW QUESTION # 155
A primaryid_c custom field exists on the candidate_c custom object. The filed is used to store each candidate's id number and is marked as Unique in the schema definition.
As part of a data enrichment process. Universal Containers has a CSV file that contains updated data for all candidates in the system, the file contains each Candidate's primary id as a data point. Universal Containers wants to upload this information into Salesforce, while ensuring all data rows are correctly mapped to a candidate in the system.

B. Create a Process Builder on the Candidate_c object to map the records.
C. Upload the CSV into a custom object related to Candidate_c.

NEW QUESTION # 156
A company decides to implement a new process where every time an Opportunity is created, a follow up Task should be created and assigned to the Opportunity Owner.
What is the most efficient way for a developer to implement this?

A. Task actions
B. Auto-launched flow on Task
C. Record-triggered flow on opportunity
D. Apex trigger on Task

Answer: C

Explanation:
To implement a process where every time an Opportunity is created, a follow-up Task should be created and assigned to the Opportunity Owner, the most efficient method is to use a Record-Triggered Flow on the Opportunity object.
Option B: Record-triggered flow on Opportunity
Declarative Solution: Salesforce Flows provide a powerful, declarative way to automate business processes without writing code.
Triggering Event: The flow is configured to trigger when a new Opportunity record is created.
Create Task Record: The flow includes an element to create a new Task record.
Set the Assigned To field to the Opportunity Owner.
Populate other Task fields as necessary (e.g., Subject, Due Date).
Efficiency: Flows are more efficient than Apex triggers for simple automation and are easier to maintain.
Best Practice: Salesforce recommends using Flows over Workflow Rules and Process Builders for new automations.
Reference:
Record-Triggered Flows
Flow Builder
Why Other Options are Less Efficient or Incorrect:
Option A: Apex trigger on Task
Incorrect Object: An Apex trigger on Task does not fulfill the requirement, as the trigger needs to be on Opportunity creation.
Code Maintenance: Requires writing and maintaining Apex code, which is less efficient for this use case.
Option C: Auto-launched flow on Task
Incorrect Trigger: Auto-launched flows do not automatically trigger on record creation unless explicitly invoked.
Does Not Meet Requirement: Does not trigger upon Opportunity creation to create a Task.
Option D: Task actions
Ambiguous Term: "Task actions" is not a specific Salesforce feature.
Possible Misinterpretation: Could refer to Workflow Actions, which are being deprecated in favor of Flows.
Conclusion:
Using a Record-Triggered Flow on the Opportunity object is the most efficient and recommended approach.
It leverages Salesforce's declarative tools and aligns with best practices for automation.
