An enterprise mobility technician is reviewing advanced mobile device wireless protocols and connection technologies for remote employees. Match each mobile networking feature on the left with its corresponding technical operational mechanism on the right.
- Wi-Fi Calling (VoWiFi)Establishes an encrypted IPsec tunnel over a wireless local area connection to transport voice packets directly to the cellular provider network.
- Bluetooth Secure Simple Pairing (SSP)Uses Elliptic Curve Diffie-Hellman (ECDH) public key exchange to establish an authenticated short-range Personal Area Network connection.
- Mobile VPN Split-TunnelingDirects corporate-bound application traffic through a secure encrypted gateway while allowing routine public internet traffic to bypass the corporate tunnel.
- USB Cellular TetheringShares a mobile device's cellular data connection with a single computer via a physical cable while preventing wireless interception.
Answer
Wi-Fi Calling corresponds to establishing an encrypted IPsec tunnel over Wi-Fi to transport carrier voice traffic. Bluetooth Secure Simple Pairing (SSP) corresponds to using Elliptic Curve Diffie-Hellman (ECDH) public key exchange for short-range authentication. Mobile VPN Split-Tunneling corresponds to directing corporate traffic through an encrypted gateway while letting public traffic bypass the tunnel. USB Cellular Tethering corresponds to sharing cellular data with a single computer over a physical cable.
Each feature accurately reflects its core technical implementation: Wi-Fi Calling uses IPsec tunnels over local 802.11 wireless networks; Bluetooth SSP leverages ECDH key exchange for personal area security; Mobile VPN split-tunneling isolates corporate traffic from public internet traffic; and USB cellular tethering provides single-device wired connection sharing over cellular data.
