PDF Platform-App-Builder Study Guide

When activating a Lightning page from the Lightning App Builder, three options are available:

Assign the page to a combination of apps and profiles. This option allows users to specify which apps and profiles will see the custom Lightning page instead of the default page.

Make the page the org default. This option makes the custom Lightning page the default for all users in the org regardless of their app or profile.

Make the page the default homepage for specific apps. This option allows users to set different homepages for different apps in Lightning Experience. [Source]

The best way to implement this request is to create a Lightning Web Component that can fetch the real-time stock price from an external API and display it on the Account record page. Installing a solution from the AppExchange may not be feasible as it may not match the exact requirements or may have additional costs. Building a Flow that uses API calls may not be efficient as it may consume API limits and may not be able to update the stock price in real-time. Using a scheduled Apex job may not be suitable as it may not be able to run frequently enough to reflect the real-time stock price

The deployed permission set will merge with the existing permission set in production, meaning changes made in the sandbox will be added to the existing permission set after deployment.References:

The app builder should verify that there is an Apex test that provides test coverage for the Flow. An Apex test is a unit test that verifies the functionality and quality of Apex code. Apex tests are required to deploy any change that contains Apex code or references Apex code, such as an auto launched flow3. The app builder should ensure that there is an Apex test that covers at least 75% of the Flow logic before deploying it to production in an active state4. Option B, C, and D are not things that the app builder should take into consideration when planning the deployment.
