A business executive needs to share their 5G smartphone's internet connection with a colleague's laptop for an urgent video conference call while traveling. They know the phone can create a hotspot but have never configured one. Which action will securely set up the mobile hotspot so the colleague can connect?
Enable USB tethering in Settings to share the phone's data connection with the laptop wirelessly.
Open Settings, select Mobile Hotspot/Tethering, set a unique SSID, and create a strong password.
Turn on the hotspot from Quick Settings and set Security to None so no password is required.
Tell the colleague to join any available open public Wi-Fi instead of configuring a personal hotspot.
The secure way to enable a mobile hotspot is to open the phone's Settings, go to the Hotspot/Tethering section, assign a distinctive network name (SSID), and set WPA2/WPA3 security with a strong password. This prevents unauthorized devices from connecting. Choosing an open network leaves the hotspot unprotected, USB tethering requires a cable and is not a Wi-Fi hotspot, and relying on public Wi-Fi does not share the phone's connection.
