Which action best isolates a mobile device from the network during seizure?

• A. Faraday bag
• B. Charger
• C. Leave the device in direct sunlight
• D. Airplane mode

Answer: (A)

Blocking all wireless signals with a Faraday bag is the most reliable way to isolate a mobile device from the network during a seizure. The bag creates a conductive enclosure that prevents cellular, Wi‑Fi, Bluetooth, GPS, and other radios from communicating with outside networks. This guarantees the device cannot contact cloud accounts, be remotely wiped, or be traced via network connections, regardless of the device’s state or power. Charging the device does not stop its radios from functioning or connecting to networks, and may even keep it active and reachable. Leaving the device in direct sunlight risks damage but does not isolate it. Relying on airplane mode depends on the user or the device’s settings and can be bypassed or re-enabled, so it isn’t a foolproof isolation method.
