Salesforce Platform Developer I (PDI) Sample Questions (Q43-Q48):NEW QUESTION # 43
An Approval Process is defined in the Expense_Item__c. A business rule dictates that whenever a user changes the Status to 'Submitted' on an Expense_Report__c record, all the Expense_Item__c records related to the expense report must enter the approval process individually. Which approach should be used to ensure the business requirement is met?
  • A. Create two Process Builder, one on Expense_Report__c to mark the related Expense_Item__c as submittable and the second on Expense_Item__c to submit the records for approval.
  • B. Create a Process Builder on Expense_Report__c with a 'Submit for Approval' action type to submit all related Expense_Item__c records when the criteria is met.
  • C. Create a Process Builder on Expense_Report__c with an 'Apex' action type to submit all related Expense_Item__c records when the criteria is met.

NEW QUESTION # 44
A developer must create a DrawList class that provides capabilities defined in the Sortable and Drawable interfaces.

Which is the correct implementation?

  • A. Option D
  • B. Option A
  • C. Option B
  • D. Option C
Answer: C
Explanation:
* Interfaces in Java and Salesforce Apex:
* In Java or Apex, interfaces define a contract that classes must fulfill. They provide method signatures that any implementing class must define.
* The keyword implements is used to implement an interface.
* Classes and Inheritance:
* A class in Java/Apex cannot use extends to inherit from an interface. The extends keyword is reserved for inheriting from another class, while implements is used for interfaces.
* Multiple Interfaces:
* A class can implement multiple interfaces in both Java and Salesforce Apex. This is done by separating interface names with commas after the implements keyword.
Correct Syntax:
To create a DrawList class that implements both Sortable and Drawable interfaces, the syntax must:
* Use implements for interfaces.
* Provide implementations for all methods defined in the interfaces.
Analysis of Options:
* Option A:
* Uses implements for each interface separately, which is syntactically incorrect in Java/Apex.
* Invalid due to redundancy.
* Option B:
* Correctly uses implements for multiple interfaces separated by a comma.
* Provides implementations for both methods, sort() and draw().
* Option C and D:
* Use extends for interfaces, which is invalid. Interfaces cannot be extended by classes.
Final Implementation:
public class DrawList implements Sortable, Drawable {
public void sort() {
// Implementation of sort method
}
public void draw() {
// Implementation of draw method
}
}
References:
* Apex Classes and Interfaces Documentation
* Trailhead Module on Apex Interfaces
Option B is the correct implementation as it adheres to the rules for working with interfaces in Java/Apex.

NEW QUESTION # 45
A developer must write an Apex method that will be called from a Lightning component. The method may delete an Account stored in the accountRec variable.
Which method should a developer use to ensure only users that should be able to delete Accounts can successfully perform deletions?
  • A. accuntRec, sObjectType,isDeletable()
  • B. accountRec, isDeletable()
  • C. Schema,sObjectType,Account, isDeletable ()
  • D. Account,isDeleteable
Answer: C
Explanation:
* Option B: Using Schema.sObjectType.Account.isDeletable() checks if the current user has permission to delete records of the Account object. This approach adheres to Salesforce's security model.
* Not Suitable:
* Option A: accountRec.isDeletable() is not a valid method.
* Option C: Incorrect syntax for checking permissions.
* Option D: Account.isDeletable does not exist.

NEW QUESTION # 46
Universal Containers is building a recruiting app with an Applicant object that stores information about an individual person and a Job object that represents a job. Each applicant may apply for more than one job.
What should a developer implement to represent that an applicant has applied for a job?
  • A. Master-detail field from Applicant to Job
  • B. Junction object between Applicant and Job
  • C. Formula field on Applicant that references Job
  • D. Lookup field from Applicant to Job
Answer: B
Explanation:
* A. Junction object between Applicant and Job:
* Since an Applicant can apply for multiple Jobs and each Job can have multiple Applicants, this is a many-to-many relationship.
* Salesforce requires a junction object to represent many-to-many relationships. The junction object will have two master-detail relationships: one to the Applicant object and one to the Job object.
* The junction object could be named something like JobApplication__c, which would represent the specific instance of an applicant applying for a particular job.
* Why this is the correct approach?
* A junction object allows for robust data management and reporting capabilities in a many-to- many relationship.
* This design ensures that each combination of applicant and job is captured as a unique record in the JobApplication__c junction object.
* It also allows storing additional details about the application, such as application date, status, and feedback.
Why not the other options?
* B. Lookup field from Applicant to Job:
* A lookup field creates a one-to-many relationship. While an Applicant could reference one Job, it does not support the many-to-many relationship required in this scenario.
* C. Master-detail field from Applicant to Job:
* A master-detail relationship is a one-to-many relationship, which is unsuitable for a many-to- many relationship. Additionally, you cannot have two master-detail fields on a single object to connect Applicant and Job directly.
* D. Formula field on Applicant that references Job:
* A formula field cannot establish relationships between records or represent a many-to-many relationship. It is only for computed fields.

* Creating Many-to-Many Relationships with Junction Objects
* Master-Detail and Lookup Relationship Details

NEW QUESTION # 47
A developer working on a time management application wants to make total hours for each timecard available to applications users. A timecard entry has a Master-Detail relationship to a timecard. Which approach should the developer use to accomplish this declaratively?
  • A. An Apex trigger that uses an Aggregate Query to calculate the hours for a given timecard and stores it in a custom field.
  • B. A Process Builder process that updates a field on the timecard entry is created.
  • C. A Roll-up Summary field on the Timecard Object that calculates the total hours from timecard entries for that timecard.
  • D. A visualforce page that calculates the total number of hours for a timecard and displays it on the page.
Answer: C
