You are responsible for setting up a secure, fault-tolerant VPN connection between on-premises and GCP. What would be the best approach to achieve this?

*Explanation:* To establish a secure and fault-tolerant VPN connection between on-premises and GCP, the best approach is to use **HA VPN with multiple interfaces (option C. **. HA VPN (High Availability VPN) provides high availability and redundancy for VPN connections. Using multiple interfaces enhances fault tolerance by allowing you to connect to multiple GCP regions or multiple VPN devices on-premises. This setup ensures that the VPN connection remains available even in the event of failures in one interface or location. Options A, B, D, and E do not provide the same level of fault tolerance as HA VPN with multiple interfaces.
