Which of the following statements is incorrect about L2TP?
- A. PPP packets can be directly transmitted on the Internet.
- B. L2TP VPN is a tunneling technology used to transmit PPP packets.
- C. L2TP VPN can provide remote access services for employees on business trips, regardless of whether they access the Internet through traditional dial-up or Ethernet.
- D. L2TP VPN is mainly used in remote office scenarios to provide remote intranet resource access for employees on business trips.
Answer: A
Explanation:
Explanation From HCIA-Security documents:
L2TP is a Layer 2 tunneling protocol designed to carry PPP frames across an IP network by encapsulating them inside L2TP tunnels. That's why statement B is correct: L2TP's job is to transport PPP traffic through a tunnel between an L2TP Access Concentrator and an L2TP Network Server. In typical remote-access VPN use, employees connect from outside (hotel, home, mobile network) and reach internal resources through the VPN, so A and D match common deployment scenarios.
The incorrect statement is C because PPP is not routable over the public Internet by itself. PPP was originally meant for point-to-point links (like dial-up or serial links). On an IP network such as the Internet, PPP frames must be encapsulated by a method like L2TP (often paired with IPsec for confidentiality and integrity) or converted via technologies such as PPPoE/PPPoA for specific access networks.
