Using a mobile hotspot can quickly establish an internet connection for the remote user. A mobile hotspot uses cellular data to create a Wi-Fi network that the user can connect to, bypassing the need for a physical connection to the ISP. This solution is practical and efficient, especially in situations where the primary internet connection is down, and immediate connectivity is required. Mobile hotspots are widely used for their convenience and the ability to provide internet access almost anywhere cellular service is available, as highlighted in the CompTIA A+ Core 1 (220-1101) Exam Objectives in sections related to networking and mobile devices .
