Scenario: During the Appium setup on a Linux server, you need to ensure that the server can handle multiple concurrent test sessions. What steps would you take to achieve this scalability?

The correct option is to use Appium Grid for parallel execution. Appium Grid allows you to run multiple tests concurrently on different devices, enhancing scalability. Increasing RAM, configuring multiple Appium servers, or installing additional testing frameworks might improve performance but won't specifically address scalability concerns.
