PDI Exam Dumps - Salesforce Certified Platform Developer (Plat-Dev-201)

The variableisOKis declared but not initialized, so its value isnull. Theif-elseconditions check for specific values ofisOK(trueorfalse), but since it isnull, none of those conditions are satisfied. The program defaults to theelseblock, assigning4tox.

When troubleshooting batch Apex jobs:

Asynchronous Job Monitoring:

Navigate toSetup > Apex Jobsto view the status of the batch job.

Provides information such as success, errors, and total execution time.

This step is crucial to diagnose whether the issue is with system limits, batch size, or specific records.

Debug Logs:

After identifying the issue in the job monitoring page, use debug logs to pinpoint specific errors or bottlenecks.

B. Check the debug logs for the batch job: Debug logs are a secondary step after checking the job status.

C. Disable and recreate with fewer records: Premature without investigating the root cause.

D. Decrease the batch size: Adjusting batch size is a solution but only after identifying the cause of the timeout.

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.

Why Developer Console?

TheDeveloper Consoleprovides tools to troubleshoot query performance, including the Query Plan tool.

The Query Plan tool evaluates SOQL query performance and provides insight into query costs and optimization.

Why Not Other Options?

A. Setup Menu: Used for administrative tasks, not performance troubleshooting.

B. Visual Studio Code IDE: Useful for development, but does not offer query performance tools.

C. AppExchange: Provides apps but does not directly help with query troubleshooting.

Event Propagation Phases in Aura Framework:

Default Phase: The framework executes handlers withevent.setDefault().

Bubble Phase: The event propagates upward from the target component to the root component.

Why Not Other Options?

A. Control: Not a valid Aura event propagation phase.

D. Emit: This is part of event creation, not propagation.

ï‚· Option B:Custom events in LWC allow data to be passed using thedetailproperty of theCustomEventobject. This is the recommended way to pass data in a custom event.

Lightning Web Components (LWC):

Fully responsive and designed to handle touch events.

Executes on stateful clients with high performance.

Aura Components:

Supports responsive designs and touch events but is slightly less efficient than LWC.

Why Not Other Options?

B. Visualforce Components: Not designed for responsiveness or touch event handling.

C. Visualforce Pages: Primarily server-rendered and not stateful for touch interactions.

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.
