Salesforce PDI Online Questions & Answers

• Question 91:

  What are three capabilities of the tag when loading JavaScript resources in Aura components? Choose 3 answers

  A. One-time loading for duplicate scripts
  B. Loading scripts in parallel
  C. Loading Files from Documents
  D. Specifying loading order
  E. Loading externally hosted scripts
  A. One-time loading for duplicate scripts
  D. Specifying loading order
  E. Loading externally hosted scripts

  ---

  Explanation

  Option A: The tag ensures that scripts are loaded only once, even if referenced multiple times.

  Option D: The tag allows you to specify the order of scripts to ensure dependencies are loaded correctly.

  Option E: Externally hosted scripts can be loaded using the scripts attribute.

  Not Suitable:

  Option B (Loading scripts in parallel): Scripts are loaded sequentially to ensure proper dependency handling.

  Option C (Loading Files from Documents): Files must be hosted externally or in static resources, not in Documents.

• Question 92:

  A developer needs to ensure that when a Contact record is deleted, all related custom child records are also deleted automatically. The relationship must support roll-up summary fields on the Contact.

  Which relationship type should the developer use?

  A. Lookup relationship with cascade delete enabled
  B. Master-detail relationship from the child object to Contact
  C. Lookup relationship from Contact to the child object
  D. External lookup relationship
  B. Master-detail relationship from the child object to Contact

  ---

  Explanation

  A master-detail relationship is the correct choice when a developer needs child records to be automatically deleted when the parent record is deleted and also wants to leverage roll-up summary fields. In Salesforce, cascade delete behavior is built into master-detail relationships, meaning that child records cannot exist without a parent and are removed automatically when the parent is deleted. Additionally, roll-up summary fields are only supported on master-detail relationships, allowing the Contact record to calculate values such as count, sum, min, or max from related child records. Lookup relationships do not support roll-up summary fields and do not enforce automatic deletion unless custom logic is implemented, making them less suitable for this requirement.

• Question 93:

  An Approval Process is defined In the Expense_item_c object. A business rule dictates that whenever a ... clients the Status to Submitted on an Expense_Item_c record related to the expense report must enter the approval process individually.

  B. The developer can use a record triggered flow with Actions.
  C. This approval step cannot be automated and must be done manually.
  D. The developer can use Einstein Next Best Actions
  A. This can only be automated with Apex code.

  Explanation

• Question 94:

  A developer wants to import 500 Opportunity records into a sandbox.

  Why should the developer choose to use Data Loader instead of Data Import Wizard?

  A. Data Loader automatically relates Opportunities to Accounts.
  B. Data Loader runs from the developer's browser.
  C. Data Import Wizard does not support Opportunities.
  D. Data Import Wizard can not import all 500 records,
  C. Data Import Wizard does not support Opportunities.

  ---

  Explanation

  Why Data Loader?

  Data Loader supports all standard and custom objects, including Opportunities.

  It is suitable for importing large data volumes like 500 records.

  Why Not Data Import Wizard?

  The Data Import Wizard does not support all objects, such as Opportunities.

  Why Not Other Options?

  A: Data Loader does not automatically relate Opportunities to Accounts unless provided external IDs.

  B: Data Loader is a desktop application, not browser-based.

  D: The Data Import Wizard can handle more than 500 records for supported objects, but it doesn't support Opportunities.

• Question 95:

  Given the following Anonymous block:

  

  What should a developer consider for an environment that has over 10,000 Case records?

  

  What should a developer consider for an environment that has over 10,000 Case records?

  A. The transaction will succeed and changes will be committed.
  B. The try-catch block will handle exceptions thrown by governor limits.
  C. The transaction will fail due to exceeding the governor limit.
  D. The try-catch block will handle any DML exceptions thrown,
  C. The transaction will fail due to exceeding the governor limit.

  ---

  Explanation

  The code provided processes all Case records in a single transaction. Since it attempts to process over 10,000 records, it exceeds the Salesforce governor limit of 50,000 DML rows per transaction, causing the transaction to fail.

  Governor Limits on DML Rows (C):Salesforce enforces a governor limit of 50,000 rows for DML operations per transaction. In this case, if the SELECT query retrieves over 50,000 records, the Database.update call will hit this limit and throw a System.LimitException.

• Question 96:

  A developer wants to ensure an Apex class respects record-level sharing rules when queried from a Lightning web component.

  Which keyword should be used in the class definition?

  A. without sharing
  B. inherited sharing
  C. with sharing
  D. global sharing
  C. with sharing

  ---

  Explanation

  The with sharing keyword enforces the organization's record-level security settings, including organization-wide defaults, role hierarchy, and sharing rules. When an Apex class is declared with with sharing, any SOQL queries executed in that class return only records the current user is allowed to access. This is essential when exposing data to user-facing components such as Lightning web components. Using without sharing bypasses record-level security and can expose sensitive data. Inherited sharing depends on the calling context and is not always predictable, while global sharing is not a valid Apex keyword.

• Question 97:

  A developer is asked to explore if this automation can be implemented without writing any Apex code.

  Which statement is true regarding this automation request?

  A. This approval step cannot be automated and must be done manually.
  B. The developer can use Einstein Next Best Actions.
  C. The developer can use a record
  D. The developer can use record triggered flow with Actions.
  C. The developer can use a record

• Question 98:

  What does the Lightning Component framework provide to developers?

  A. Support for Classic and Lightning UIs
  B. Prebuilt components that can be reused
  C. Templates to create custom components
  D. Extended governor limits for applications
  B. Prebuilt components that can be reused

  ---

  Explanation

  Why Prebuilt Components?

  The Lightning Component Framework includes a library of prebuilt components, which developers can use to build applications faster.

  Why Not Other Options?

  A: The framework is exclusive to Lightning Experience, not Classic UI.

  C: The framework does not provide templates but focuses on reusable components.

  D: Extended governor limits are not provided by the framework.

• Question 99:

  Universal Container uses Salesforce to create orders.

  When an order is created, it needs to sync with the-in-house order fulfillment system.

  The order fulfillment system can accept SOAP messages over the HTTPS.

  If the connection fails, messages should be retried for up to 24 hours.

  What is the recommended approach to sync the orders in Salesforce with the order fulfillment system?

  A. Set up a Workflow Rule outbound message to the order fulfillment system.
  B. Create an after insert trigger on the Order object to make a callout to the order fulfilment system
  C. Write an Apex SOAP service to integrate with the order fulfillment system.
  D. Use Process Bulkier to call an invocable Apex method that sends a message to the order fulfilment system.
  B. Create an after insert trigger on the Order object to make a callout to the order fulfilment system
