Option C: Roll-up summary fields can cause triggers to fire again as they recalculate parent records.

Option D: After-save record-triggered flows can update records, which may fire triggers on those records.

75% Code Coverage (A):To deploy Apex code to production, Salesforce requires at least 75% of the code to be covered by tests across the organization.

Option A: Only one method annotated with @InvocableMethod can exist per class.

Option C: The method must be static.

Option E: The method can be declared as Public or Global for broader accessibility.

A before trigger fires when records are inserted, updated, or deleted. Using the Data Loader or Bulk API to import data updates records, which triggers the before insert or before update events.

Option A: Renaming or replacing picklists does not trigger a record-level operation.

Option B: The Mass Address Update tool is not a record operation that triggers before triggers.

Option D: Converting leads to contacts triggers lead conversion events, not directly related to Account triggers.

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.

LWC Overview: https://developer.salesforce.com/docs/component-library/documentation/en/lwc

References:

Public Method (A):The parent component can call a public method defined in the child component to pass data directly.

 Lightning Component Quick Action (C):Using a Lightning component ensures the user can trigger the HTTP REST callout via a button click on the Opportunity detail page. This provides a seamless user interface experience in Lightning Experience.

To notify the parent component when the child component’s Next button is clicked, the child component can dispatch a custom event. The parent component listens to this event and handles navigation accordingly.

Visual Studio Code (VS Code) is the recommended tool for Salesforce development. It supports the Salesforce Extensions Pack for debugging and fixing issues in Lightning Web Components (LWCs).

Not Suitable:

Option A: The Developer Console is less effective for LWC debugging.

Option B: The Force.com IDE is deprecated.

Option C: Execute Anonymous does not provide tools to debug or fix LWC bugs.

Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.

Why not other options?

A: Null values in the Vendor records do not prevent the change.

C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.

D: Organization-wide defaults do not affect the ability to change relationships.
