Salesforce Updated PDI Exam Questions and Answers by zarah

A validation rule can ensure that theLead Sourcefield is populated before the Lead is converted. This prevents users from proceeding unless the required data is entered.

Why not other options?

A: Triggers are programmatic, whereas a declarative solution like validation rules is simpler and more efficient.

B: Lead Conversion field mapping maps fields between Lead and Account/Contact but cannot enforce field requirements.

C: A formula field is read-only and cannot enforce user input.

Validation Rules Documentation

Using a formula field is the most efficient solution to calculate the ratio between rejected and approved timesheets. It minimizes maintenance overhead by dynamically calculating the value based on the existing roll-up summary fields.

Example Formula:

Total_Rejected_Timesheets__c / Total_Approved_Timesheets__c

A: Thesave()method in the custom controller must be tested to ensure it works as intended and redirects to the correct page.

B: Setting parameters viaApexPages.currentPage().getParameters()is crucial to test scenarios where user input or URL parameters drive logic.

D: UsingTest.setCurrentPage(pageRef)is essential for simulating page context in unit tests.

Why not other options?

C: This statement does not belong to testing a custom controller.

B (second occurrence): It appears to be incorrectly formatted in the question.

Testing Apex Controllers

A. Junction object between Applicant and Job:

Since anApplicantcan apply for multipleJobsand eachJobcan have multipleApplicants, this is amany-to-many relationship.

Salesforce requires ajunction objectto 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.
