What is an important feature of public gateways?

Public gateways are designed to streamline and facilitate external access to internet-based applications, making option C the correct choice. They serve as entry points for users to access cloud services and applications over the internet, simplifying connectivity for users and organizations. By offering a dedicated pathway for external access, public gateways make it easier for users to interact with applications hosted on the cloud without needing intricate networking setups.

Their primary function eliminates many of the complexities associated with network management, as they provide a direct and efficient means for users to connect to the services they need. This enhances user experience, promoting efficiency and ease of access to critical business applications and resources.

In the context of the other choices, while public gateways can allow for secure remote access to virtual private networks, this is not their primary function and they do not inherently provide encryption for data in transit—these capabilities are usually associated more closely with VPNs and security protocols. Additionally, the assertion that they increase complexity of network management contrasts with their core benefit of simplifying external access.
