Salesforce PDI Online Questions & Answers

• Question 101:

  A developer needs to create a custom button for the Account object that, when clicked, will perform a series of calculations and redirect the user to a custom Visualforce page. The developer wants to ensure the Visualforce page matches the Lightning Experience user interface.

  What attribute needs to be defined within the tag to meet the requirement?

  A. applyHtmlTag="true"
  B. wizard=true"
  C. setup="true"
  D. lightningStylesheets=''true"
  D. lightningStylesheets=''true"

  Explanation

• Question 102:

  Universal Containers wants to back up all of the data and attachments in its Salesforce org once a month.

  Which approach should a developer use to meet this requirement?

  A. Schedule a report.
  B. Use the Data Loader command line.
  C. Define a Data Export scheduled job.
  D. Create a Schedulable Apex class.
  C. Define a Data Export scheduled job.

  ---

  Explanation

  Why Data Export Scheduled Job?

  Salesforce provides an out-of-the-box Data Export feature that allows organizations to back up their data, including attachments.

  This feature can be scheduled to run automatically on a monthly basis, fulfilling the requirement.

  Why Not Other Options?

  A. Schedule a Report: Does not export attachments and is limited to reportable data.

  B. Data Loader Command Line: Requires manual setup and scripting, which is unnecessary for this requirement.

  D. Create a Schedulable Apex class: Not suitable, as the Data Export tool is more efficient for full data and attachment backup.

• Question 103:

  Which statement should be used to allow some of the records in a list of records to be inserted if others fail to be inserted?

  A. Database. insert (records, true)
  B. insert records
  C. insert (records, false)
  D. Database. insert (records, false)
  D. Database. insert (records, false)

  ---

  Explanation

  Database.insert(records, false):

  The Database.insert() method with the allOrNone parameter set to false allows for partial success.

  If some records in the list fail due to validation rules, triggers, or other errors, the method will still attempt to insert the remaining valid records.

  The false parameter ensures that records that fail will not roll back the transaction for the others.

  Why not the other options?

  A. Database.insert(records, true):

  The true parameter makes the operation transactional (all or none). If any record fails, all records will roll back.

  B. insert records:

  The insert DML statement behaves like Database.insert(records, true) by default and rolls back all records if any error occurs.

  C. insert(records, false):

  This syntax is invalid in Apex.

• Question 104:

  A developer has the following requirements:

  1. Calculate the total amount on an Order.

  2. Calculate the line amount for each Line Item based on quantity selected and price.

  3. Move Line Items to a different Order if a Line Item is not in stock.

  Which relationship implementation supports these requirements on its own?

  A. Line Item has a re-parentable master-detail field to Order.
  B. Line Item has a re-parentable lookup field to Order.
  C. Order has a re-parentable lookup field to Line Item.
  D. Order has are-parentable master-detail field to Line Item.
  A. Line Item has a re-parentable master-detail field to Order.

  ---

  Explanation

  Why Re-Parentable Master-Detail Field?

  A master-detail relationship allows Line Items to roll up totals (e.g., calculate total amount) to the Order.

  Setting the relationship as re-parentable supports moving Line Items between different Orders.

  Why Not Other Options?

  B. Lookup field: Does not support roll-up summary fields for calculations.

  C and D: Relationships in the opposite direction (Order to Line Item) do not support the required logic.

• Question 105:

  In the following example, which sharing context will myMethod execute when it is invoked?

  

  A. Sharing rules will be enforced by the instantiating class.
  B. Sharing rules will be enforced for the running user.
  C. Sharing rules will not be enforced for the running user.
  D. Sharing rules will be inherited from the calling context.
  C. Sharing rules will not be enforced for the running user.

  ---

  Explanation

  In the provided code snippet, the class myClass does not specify a sharing declaration (with sharing or without sharing). In Salesforce, when a class does not explicitly declare its sharing context, it defaults to without sharing. This means sharing rules are not enforced.

• Question 106:

  A developer wants to mark each Account in a List as either Active or Inactive, based on the value in the LastModified each Account being greater than 90 days in the past.

  Which Apex technique should the developer use?

  A. An if-else statement, with a for loop inside
  B. A witch statement, with a for loop inside
  C. A for loop, with an if or if/else statement inside
  D. A for loop, with a switch statement inside
  C. A for loop, with an if or if/else statement inside

  ---

  Explanation

  The developer must iterate over each Account in the list and evaluate a date-based condition (LastModifiedDate compared to 90 days ago). This requires looping through the list first, then using an if or if/else statement to mark each record as Active or Inactive. Switch statements are not suitable for evaluating range or date comparison logic.

• Question 107:

  Which exception type cannot be caught?

  A. custom exception Limit
  B. LinkException
  C. NoAccessException
  D. CelloutException
  B. LinkException

  ---

  Explanation

  LimitException cannot be caught in a try-catch block because it is thrown when governor limits are exceeded, and Salesforce does not allow further processing in such cases.

  Other exceptions, such as custom exceptions, NoAccessException, or CalloutException, can be caught and handled.

• Question 108:

  Which process automation should be used to post a message to Chatter without using Apex code?

  A. Outbound Message
  B. Entitlement Process
  C. Strategy Builder
  D. Flow Builder
  D. Flow Builder

  ---

  Explanation

• Question 109:

  A developer has a single custom controller class that works with a Visualforce Wizard to support creating and editing multiple sObjects. The wizard accepts data from user inputs across multiple Visualforce pages and from a parameter on the initial URL.

  Which three statements are useful inside the unit test to effectively test the custom controller? Choose 3 answers

  A. String nextPage = controller.save().getUrl ();
  B. ApexPages.currentPage ().getParametera(}.put{'input', "TeatValue');
  C. insert pageret;
  D. public Extendedcontroller (ApexPages.Standardcontraller entrl) { }
  E. Test. setCurrentPage (pageRef) ;
  A. String nextPage = controller.save().getUrl ();
  B. ApexPages.currentPage ().getParametera(}.put{'input', "TeatValue');
  E. Test. setCurrentPage (pageRef) ;

  ---

  Explanation

  Calling controller.save().getUrl() allows the test to verify navigation logic in the Visualforce wizard.

  Using ApexPages.currentPage().getParameters().put('input','TestValue') simulates URL parameters passed into the controller, which is required because the wizard reads from the initial URL.

  Using Test.setCurrentPage(pageRef) sets the Visualforce page context so that page parameters and controller logic depending on the current page can execute correctly.

  The constructor signature itself is not a test statement, and inserting a PageReference is invalid because PageReference is not an sObject.

• Question 110:

  A developer wants to automate logic when a record is created or updated, without writing Apex code.

  Which tool should be used?

  A. Apex trigger
  B. Validation rule
  C. Record-triggered Flow
  D. Workflow rule
  C. Record-triggered Flow

  ---

  Explanation

  Record-triggered Flows are the recommended declarative automation tool for responding to record creation and updates. They allow developers and administrators to define logic, conditions, and actions without writing Apex code. Record-triggered Flows can run before or after the record is saved and support complex branching logic, making them more powerful and flexible than workflow rules. Apex triggers are programmatic and require code, while validation rules only enforce constraints and cannot perform automation. Workflow rules are legacy tools and offer limited functionality compared to flows.
