Salesforce PDI Online Questions & Answers

• Question 251:

  Universal Containers wants to automatically assign new cases to the appropriate support representative based on the case origin. They have created a custom field on the Case object to store the support representative name.

  What is the best solution to assign the case to the appropriate support representative?

  A. Use a trigger on the Case object.
  B. Use a formula field on the Case object.
  C. Use a validation rule on the Case object.
  D. Use an Assignment Flow element.
  D. Use an Assignment Flow element.

  ---

  Explanation

  A Flow with an Assignment element is the best declarative solution to assign cases based on criteria such as Case Origin. It can automatically evaluate the value of the Case Origin and assign the support representative.

  Why not other options?

  A: Using a trigger is a programmatic approach and less ideal when declarative tools can solve the problem.

  B: A formula field cannot assign values; it only calculates and displays results.

  C: Validation rules are used to enforce constraints, not for assigning values.

• Question 252:

  A business implemented a magnification plan to encourage its customers to watch some educational videos.

  Customers can watch videos over several days, and their progress is recorded. Award points are granted to customers for all completed videos. When the video is marked as completed in Salesforce, an external web service must be called so that points can be awarded to the user.

  A developer implemented these requirements in the after update trigger by making a calf to an external web service. However, a System.CalloutException is occurring.

  What should the developer do to fix this error?

  A. Surround the external call with a try-catch block to handle the exception.
  B. Write a REST service to integrate with the external web service.
  C. Move the callout to an asynchronous method with structure (callout=true) annotation.
  D. Replace the after update trigger with a before insert trigger.
  C. Move the callout to an asynchronous method with structure (callout=true) annotation.

• Question 253:

  Management asked for opportunities to be automatically created for accounts with annual revenue greater than $1, 000,000. A developer created the following trigger on the Account object to satisfy this requirement.

  

  Users are able to update the account records via the UI and can see an opportunity created for high annual revenue accounts.

  However, when the administrator tries to upload a list of 179 accounts using Data Loader, it fails with system, Exception errors.

  Which two actions should the developer take to fix the code segment shown above? Choose 2 answers

  A. Query for existing opportunities outside the for loop.
  B. Check if all the required fields for Opportunity are being added on creation.
  C. Move the DML that saves opportunities outside the for loop.
  D. Use Database query to query the opportunities.
  A. Query for existing opportunities outside the for loop.
  C. Move the DML that saves opportunities outside the for loop.

• Question 254:

  A developer creates a new Apex trigger with a helper class, and writes a test class that only exercises 95% coverage of the new Apex helper class.

  Change Set deployment to production fails with the test coverage warning:

  "Test coverage of selected Apex Trigger is 0%, at least 1% test coverage is required."

  What should the developer do to successfully deploy the new Apex trigger and helper class?

  A. Run the tests using the Run All Tests' method.
  B. Remove the failing test methods from the test class
  C. Create a test class and methods to cover the Apex trigger.
  D. Increase the test class coverage on the helper class.
  C. Create a test class and methods to cover the Apex trigger.

  ---

  Explanation

  The deployment fails because the Apex trigger has 0% test coverage. Even though the helper class is covered, Salesforce requires at least 1% test coverage for the trigger itself. To resolve this, a test class and methods must specifically invoke the trigger by performing DML operations on the related object.

• Question 255:

  A developer is embedding a Lightning component inside a Visualforce page.

  Which tag is required to include the Lightning framework?

  A. apex:includeLightning/
  B. ltng:require
  C. apex:slds/
  D. lightning:container
  A. apex:includeLightning/

  ---

  Explanation

  The apex:includeLightning/ tag is required to load the Lightning framework when embedding Lightning components within a Visualforce page. This tag ensures that the necessary JavaScript libraries are available so that Lightning components can be instantiated and rendered correctly. The ltng:require tag is used within Aura components to load external resources, while apex:slds/ includes styling resources only. The lightning:container component is used for specific embedding scenarios and does not replace the need to include the Lightning framework.

• Question 256:

  A developer is asked to prevent anyone other than a user with Sales Manager profile from changing the Opportunity Status to Closed Lost if the lost reason is blank.

  Which automation allows the developer to satisfy this requirement in the most efficient manner?

  A. An Apex trigger on the Opportunity object
  B. An error condition formula on a validation rule on Opportunity
  C. A record trigger flow on the Opportunity object
  D. An approval process on the Opportunity object
  B. An error condition formula on a validation rule on Opportunity

  ---

  Explanation

  Why Validation Rule?

  Validation rules are efficient for enforcing field-level conditions without requiring Apex or Flow.

  A formula can check if the user's profile is not "Sales Manager" and if the Lost Reason field is blank when Status is set to "Closed Lost".

  Why Not Other Options?

  A: Triggers are more complex and unnecessary for this simple validation.

  C: Record-triggered flows are less efficient for field validations compared to validation rules.

  D: Approval processes do not handle this type of field-level restriction.

• Question 257:

  AW Computing (AWC) handles orders In Salesforce and stores Its product Inventory In a fter, inventory_c, on a custom object, Product_c. When en order for a Product_c Is placed, the inventory_c field Is reduced by the quantity of the order using an Apex trigger.

  

  AWC wants the real-time inventory reduction for a product to be sent to many of Its external systems, Including some future systems the company Is currently planning.

  What should a developer add to the code at the placeholder to meet these requirements?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 258:

  Universal Containers wants to ensure that all new leads created in the system have a valid email address. They have already created a validation rule to enforce this requirement, but want to add an additional layer of validation using automation.

  What would be the best solution for this requirement?

  A. Submit a REST API Callout with a JSON payload and validate the fields on a third party system
  B. Use a before-save Apex trigger on the Lead object to validate the email address and display an error message if it is invalid
  C. Use a custom Lightning Web component to make a callout to validate the fields on a third party system.
  D. Use an Approval Process to enforce the completion of a valid email address using an outbound message action.
  B. Use a before-save Apex trigger on the Lead object to validate the email address and display an error message if it is invalid

  ---

  Explanation

  Before-save Apex Trigger:

  This is the best solution because a before-save trigger runs before the record is saved to the database, providing an opportunity to validate or modify the data.

  In this case, the Apex trigger can validate the email address using a regular expression or a third- party API call to ensure the email address is valid. If the email is invalid, an error message can be displayed using addError().

  Why not the other options?

  A. Submit a REST API Callout with a JSON payload:

  REST callouts are more complex and generally not recommended for simple validation tasks like email format validation. Additionally, callouts cannot be performed directly in a before-save trigger.

  C. Use a custom Lightning Web Component (LWC):

  LWCs are primarily for UI interactions and should not be used to enforce data validations that are server-side requirements.

  D. Use an Approval Process:

  Approval Processes are for managing the approval flow of records, not for real-time validations. They cannot enforce email validation directly.

• Question 259:

  A developer needs to schedule Apex code to run nightly.

  Which interface should the Apex class implement?

  A. Batchable
  B. Queueable
  C. Schedulable
  D. Callable
  C. Schedulable

  ---

  Explanation

  To schedule Apex code to run at a specific time or on a recurring basis, the class must implement the Schedulable interface. This interface requires the implementation of the execute method, which contains the logic to run when the scheduled job executes. While Batchable and Queueable interfaces support asynchronous processing, they do not provide scheduling capabilities on their own. Schedulable classes can also invoke batch or queueable jobs if more complex processing is required.

• Question 260:

  Which two sfdx commands can be used to add testing data to a Developer sandbox?

  A. Forced: data:bulk:upsert
  B. Forced: data: object :upsert
  C. Forced: data: tree: upsert
  D. Forced: data:async:upsert
  A. Forced: data:bulk:upsert
  C. Forced: data: tree: upsert
