No.# C,D E https://developer.salesforce.com/docs/platform/lwc/guide/testing.html#:~:text=Write%20Jest%20tests%20to:%20*%20Test%20a,*%20Verify%20that%20events%20fire%20when%20expected.

I passed with such a high score.
I really appreciate your dump PDII help.

No.# Yes, I agree with Mauricio.
Correct option is D - Create a formula field that substitutes NULL values for a string of text, create an index for the formula field, then use the formula within the WHERE clause.

As part of a new integration, a developer is asked to implement a custom search functionality that:
Can perform unrestricted queries
Can account for all values including NULL in a custom picklist field Type__c on the Opportunity object
The Opportunity object has OWD = Public Read-Only
Custom index has been created for Type__c
Dataset contains over 5 million records with many NULLs

No.# Answer should be C,D & E

C. To verify the DOM output of a component
✔️ Correct. Jest tests can inspect the rendered DOM to verify that the expected HTML structure or values appear based on component logic or user input.

D. To verify that events fire when expected
✔️ Correct. You can use Jest to mock and assert that CustomEvents are dispatched correctly from your LWC component.

E. To test basic user interaction
✔️ Correct. Jest is commonly used to simulate user interaction like button clicks, input changes, and form submissions to verify component behavior.

No.# An org has an existing process, built using Process Builder, on Opportunity that sets a custom field, CcommissionBaseAmount _c, when
an Opportunity is edited and the Opportunity's Amount changes.
A developer recently deployed an Opportunity before update trigger that uses the CommissionBaseAmount__c and complex logic to calculate a
value for a custom field, CommissionAmount c, when an Opportunity stage changes to Closed/Won.
Users report that when they change the Opportunity to Closed/Won and also change the Amount during the same save,
the CommissionAmount __c is incorrect.
Which action should the developer take to correct this problem?

A. Replace the process with a Fast Field Update record-trigger flow.
B. Call the trigger from the process,
C. Call the process from the trigger.

other version of this question .
Ans is A for this question.

No.# Ans is
B. Account a = MyRemoter.getAccount('TestAccount');
System.assertEquals('TestAccount', a.Name);

No.# Correct Answer : A Create and Dispatch a custom event

No.# Ans is C :
@Mauricio
Rewrite the business logic and use @TestVisible ------> @TestVisible is used to expose private methods/variables to test classes — it doesn't bypass callouts or solve DML issues.


The error message:

"You have uncommitted work pending. Please commit or rollback before calling out."

...means your code is attempting to make an HTTP callout after performing a DML operation, which is not allowed in the same transaction.

In test classes, this is especially common if:
You’re running business logic that performs DML and callouts.
The callout is real or not mocked with HttpCalloutMock.

No.# Ans is Validation rules.
Even though Validation Rules only show one error per field, they do support showing multiple field-level errors simultaneously — which is what users usually want — with no JavaScript required.

So if:

You have validation rules targeting different fields (e.g., Email, Phone, Company),
And you're using lightning-record-edit-form with lightning-input-field,

Then when the user clicks Submit, Salesforce will automatically show all field errors inline — one per field — with no JavaScript needed.

I passed PDII exam with a high score.

I have passed the exam successfully for this set of PDII exam questions only. It is so helpful that i suggest all the candidates to make a worthy purchase of it. You won't regret for it.

These PDII exam questions are the latest you should have and they are accurate. I took the exam in the last day of this month, and i passed with a high score out of my expection. Thanks!

No.# When dealing with a large data volume (e.g., 100,000 child records per parent record), triggers are not an ideal solution because they can quickly run into governor limits such as:

SOQL Query Limit: Triggers have a limit on the number of SOQL queries that can be executed per transaction.
DML Statement Limit: Large DML operations can exceed transaction limits.
Using a batch job is the recommended approach because it allows processing large datasets in manageable chunks, avoiding governor limits. Additionally, by scheduling the batch job using Database.Schedulable, the update process can be executed asynchronously.

No.# Answer is C :
In Aura, application events are used when you need to communicate information across multiple, independent components in the application. Since this scenario involves multiple components on the same page that are not directly related, an application event is ideal. When the c:searchAccounts component selects an Account, firing an application event allows all other components on the page to react to that selection and display relevant information without requiring them to be in a parent-child relationship.

No.# True , reference :

No.# I think it's A .
Salesforce validation rules are declarative and can be used to validate more than one field on an object and display multiple error messages. This approach requires minimal JavaScript code and uses Salesforce's built-in validation framework.

No.# A is correct

No.# Answer is A :
https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_js_remoting_compare_remote_objects.htm

- Visualforce Remote Objects:
Makes basic “CRUD” object access easy
Doesn’t require any Apex code
Supports minimal server-side application logic
Doesn’t provide automatic relationship traversals; you must look up related objects yourself

- JavaScript Remoting:
Requires both JavaScript and Apex code
Supports complex server-side application logic
Handles complex object relationships better
Uses network connections (even) more efficiently

No.# true , reference :

No.# This is why C is correct :

Salesforce releases can vary between production and sandbox environments, especially if the sandbox was refreshed before a production release. New Salesforce releases introduce changes to platform behavior, new features, and potentially new or altered behaviors in code execution. If the sandbox is on a newer or different release than production, it might execute code differently, leading to unexpected test failures in the sandbox.
