Which technology provides encrypted remote access to the corporate network when traveling with a laptop?

• A. VPN
• B. SSH
• C. FTP
• D. Telnet

Answer: (A)

When you’re on the road with a laptop, you need to access your company’s internal network securely over public internet. A VPN (Virtual Private Network) creates an encrypted tunnel between your laptop and the corporate network, so your data stays private and your device appears as if it’s on the office network. This leaves you access to internal resources, applications, and services just like you were physically in the building, while keeping the connection protected from eavesdropping or tampering.

SSH is meant for securing access to a single machine or for tunneling specific services, not for providing full, typical access to an entire corporate LAN. FTP transfers files and is not encrypted by default (unless using FTPS/SFTP). Telnet is an old protocol that sends data in plain text, offering no encryption. So for secure, broad remote access to the corporate network, a VPN is the appropriate and best choice.
