- remote access VPN over the Internet
Explanation: A remote access VPN over the Internet is an appropriate solution to meet the requirement for secure connections to individual teleworkers. Site-to-site VPNs are used to connect between offices. Leased lines are very expensive for multiple teleworkers. A dial-up connection is very slow and the corporation needs to maintain a facility (a bank of access servers) to handle multiple simultaneous dial-up connections.
