Question

All of the following statements about virtual private networks are correct except:

a) They provide secure communication over the Internet
b) They use encryption to protect data
c) They require a dedicated physical network
d) They enable remote access to a private network

Answer 1

Virtual private networks (VPNs) provide secure communication over the Internet using encryption, enable remote access to a private network, but do not require a dedicated physical network.

Step-by-step explanation:

A virtual private network (VPN) is a technology that allows secure communication over the Internet by creating an encrypted connection between the user's device and the private network. It provides a secure tunnel for data transmission, protecting it from unauthorized access.

VPNs use encryption protocols to ensure the confidentiality and integrity of data. By encrypting the data, it becomes unreadable to anyone without the proper decryption key, providing an additional layer of security.

Contrary to statement c), virtual private networks do not require a dedicated physical network. Instead, they utilize existing networks, such as the Internet, to establish a secure connection between the user and the private network.

Therefore, the correct answer is c) They require a dedicated physical network.

Answer 2

VPNs do not require a dedicated physical network, unlike traditional private networks. They operate over existing public infrastructure, enhancing flexibility and cost-effectiveness.Thus,the correct option is c.

Step-by-step explanation:

Contrary to the statement, VPNs don't necessitate a dedicated physical network. Unlike traditional private networks that rely on exclusive physical infrastructure, VPNs leverage existing public networks, such as the Internet.

The term "virtual" underscores the key distinction, signifying that VPNs operate over shared infrastructure rather than requiring a dedicated network. This characteristic enhances the flexibility and cost-effectiveness of VPNs, allowing organizations to establish secure communication channels without the need for a separate, exclusive physical network.

To clarify, the incorrect assertion arises from a misunderstanding of VPN architecture. VPNs are designed to provide secure communication, encryption for data protection, and facilitate remote access to private networks.

However, the idea that they demand a dedicated physical network is inaccurate. This misperception may stem from the term "private network," but the virtual aspect of VPNs is fundamental to their operation, enabling organizations to achieve secure connectivity without the constraints of a dedicated physical infrastructure.

Therefore,the correct option is c.
