PDI Exam Dumps - Salesforce Developers Questions and Answers

Tooling API:

The Tooling API provides programmatic access to manage tests and other metadata in the org.

It can execute test classes or methods remotely.

Developer Console:

The Developer Console is a built-in Salesforce tool to execute Apex tests, debug logs, and more.

Allows developers to execute tests interactively.

B. Metadata API: Used for managing metadata, not for running tests.

C. Bulk API: Used for data operations, not related to testing.

Tooling API Overview: https://developer.salesforce.com/docs/atlas.en-us.api_tooling.meta/api_tooling/

Testing with Developer Console: https://help.salesforce.com/s/articleView?id=sf.code_dev_console_test.htm

The recordSetVar attribute of the tag allows a Visualforce page to handle multiple records, which is ideal for list buttons that display a page for bulk editing.

Why not other options?

A: Standard controllers can be extended, but using recordSetVar is the direct and best-supported method for this scenario.

B: There is no such concept as a "Custom List Controller" in Visualforce.

C: is not a valid Visualforce tag.

In Aura components:

B. Renderer: Contains custom rendering logic.

C. Controller: Manages user interaction and component events.

E. Helper: Contains reusable JavaScript functions for logic.

The Lightning Out library allows a Lightning Web Component to be embedded in a Visualforce page. This approach is the most suitable to make the LWC accessible in Salesforce Classic.

The Boolean isOK variable is declared but not initialized, meaning its value is null by default in Apex.

The code evaluates the if-else conditions in sequence:

Condition 1: isOK == false && theString == 'Hello'

isOK is null, so this evaluates to false.

Condition 2: isOK == true && theString == 'Hello'

Again, isOK is null, so this evaluates to false.

Condition 3: isOK != null && theString == 'Hello'

isOK is null, so isOK != null evaluates to false.

Else block: None of the above conditions are true, so the code enters the else block and sets x = 4.

When running a flow in debug mode, Salesforce rolls back any DML operations performed during the debugging process to ensure no data changes affect the org. This helps test and verify flow logic without impacting live data.

In Visualforce, data-binding requires getter and setter methods to access the attributes of a controller. Adding a getter method for actType ensures that its value is retrieved properly.

Lightning Web Components (LWCs) have access to a variety of resources in Salesforce. Below are the supported resources:

Static Resources (A):You can use static resources to reference JavaScript libraries, images, and other files needed in an LWC.

The @TestVisible annotation allows private methods or variables to be accessed in test classes. This ensures that the private method can be adequately tested without changing its access modifier.

Change sets can only be used between related organizations:

Change sets require a relationship between the source and target Salesforce orgs, such as a production org and its sandboxes. You cannot use change sets between unrelated Salesforce orgs.
