Which type of network allows secure access to an organization's network over the Internet?

A virtual private network (VPN) is the correct choice because it provides a secure channel for connecting to an organization's network over the Internet. A VPN uses encryption and other security measures to create a private tunnel through the public Internet, allowing users to send and receive data securely. This is especially important for remote workers who need to access sensitive information or organizational resources while ensuring that their connection is protected from potential threats.

In contrast, a wireless local area network (WLAN) typically provides network access within a localized area, such as an office or home, without the additional layer of security required for Internet transmission. A personal area network (PAN) connects devices over a short range, often using Bluetooth, which is suitable for personal device connectivity but not for secure remote access. A local area network (LAN) connects computers and devices within a limited geographic area but does not inherently provide the security features necessary for Internet access. Therefore, the VPN stands out as the best option for securely accessing an organization's network through an external connection.
