A company is implementing a client-to-site VPN based on tunnel-mode IPsec.
Which devices are responsible for the IPsec encapsulation?
- A. The remote clients and devices accessed by the clients at the main site
- B. Gateways at the remote clients' locations and devices accessed by the clients at the main site
- C. The remote clients and a gateway at the main site
- D. Gateways at the remote clients' locations and a gateway at the main site
Answer: C
Explanation:
In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.
1.IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.
2.Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.
3.Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.
