To make a Lightning record page dynamic and tailored to a user's role, an administrator should use component visibility filters. This feature, available in the Lightning App Builder, allows components to be displayed or hidden based on specific criteria. These criteria can be defined using the user's role, profile, or permissions, as well as field values on the record itself. This directly addresses the requirement to show users information that is most relevant and useful for their specific job function, thereby making the page dynamic and easier to use by reducing clutter.

B. Remove fields from the record details component: This is a static change applied via the page layout and affects all users assigned to it, failing to make the page dynamic for different roles.

C. Delete the extra component from the page: This simplifies the page for all users but does not provide a dynamic, role-specific experience as requested.

D. Include more tab components with filters: Adding more tabs can increase complexity. While tabs can contain filtered components, the core feature enabling the dynamic behavior is the component visibility filter itself, making option A more precise.

1. Salesforce Help Documentation: Dynamic Lightning Pages. This document states

"You can make your Lightning record pages more dynamic by configuring component visibility filters on them... For example

you can create a rule for a component to appear for users in a certain role..." This directly supports using component visibility filters to tailor pages by user role.

2. Trailhead Module: Lightning App Builder

Unit: Create Dynamic Pages with Component Visibility Rules. This unit details the process: "With component visibility rules

you can make your Lightning record pages more dynamic by choosing when a component appears... You can add visibility rule filters to a component based on the user’s profile

role

or permissions."

3. Salesforce Developer Documentation: Lightning App Builder Guide

Section: Configure Component Visibility. This guide explains that visibility filters can be based on "User fields

such as Profile or Role

" which is the exact requirement of the scenario.
