Firewall Configuration for VPN Traffic

A company has two geographically separate locations that need to connect using a VPN.

Which of the following devices must be specifically configured to allow VPN traffic into the network?

A.

Firewall

B.

Switch

C.

Router

D.

Modem.

A.

The correct answer is A) Firewall.

A VPN (Virtual Private Network) is a secure way of establishing a connection between two separate networks over the internet. In the given scenario, two geographically separate locations need to connect using a VPN, which means that the data will be encrypted and secure while being transmitted over the internet.

Firewalls are devices that filter network traffic and control access to and from a network. In order for VPN traffic to pass through a network, the firewall must be specifically configured to allow VPN traffic into the network. This is because firewalls are designed to block or restrict access to unauthorized or potentially harmful traffic.

Switches and routers are networking devices that allow for the flow of data between different networks or devices, but they do not have the specific security features that a firewall has. While a modem is used to connect a network to the internet, it does not have the ability to filter or control traffic in the same way a firewall does.

Therefore, in order to allow VPN traffic into the network, the firewall must be configured to allow it.
