Which scenario is an example of remote access VPNs?

Question

Remote-access VPNs let an individual user establish an encrypted connection from a remote device over a public network (like the Internet) to a corporate network, typically using a VPN client or built-in OS VPN capability. Site-to-site VPNs (also called gateway-to-gateway VPNs) connect entire networks or offices through permanent or semi-permanent tunnels between routers or firewalls.

Step-by-step reasoning:
1. Identify key distinction: remote-access = individual device/user connecting to corporate resources; site-to-site = network-to-network connection handled by gateway devices.
2. Examine option A: "A mobile sales agent is connecting to the company network via the Internet connection at a hotel." This describes a single user at a transient location using the hotel Internet to reach the company—typical remote-access VPN behavior.
3. Examine option B: "A toy manufacturer has a permanent VPN connection to one of its parts suppliers." A permanent connection between two organizations is a site-to-site VPN connecting two networks, not an individual remote-access session.
4. Examine option C: "All users at a large branch office can access company resources through a single VPN connection." When an entire branch’s traffic goes through a single tunnel or gateway, that is a site-to-site VPN (branch gateway to HQ gateway).
5. Examine option D: "A small branch office with three employees has a Cisco ASA that is used to create a VPN connection to the HQ." A Cisco ASA acting as the branch gateway to establish a VPN tunnel to headquarters describes a site-to-site VPN, even if the branch is small.

Why the correct answer is correct:
- Option A fits the defining characteristics of remote-access VPNs: one user, dynamic location (hotel), client-to-network encrypted session over the Internet. It’s not a persistent gateway-to-gateway tunnel.

Why other options are incorrect:
- B, C, and D describe gateway-to-gateway or permanent connections between networks (site-to-site VPNs), not individual remote-user connections.

Conclusion: The correct answer is "A mobile sales agent is connecting to the company network via the Internet connection at a hotel," which matches the provided answer.
