What command is used to provide overall counters related to all active VPNs?

• A. get vpn ipsec stats tunnel
• B. get vpn status
• C. show vpn connections
• D. list active vpns

Answer: (A)

The command that provides overall counters related to all active VPNs is "get vpn ipsec stats tunnel." This command specifically retrieves statistics about IPsec VPN tunnels, including details such as the number of packets sent and received, encryption and authentication statistics, and other performance metrics relevant to all active VPN tunnels. This information is crucial for monitoring the health and performance of VPN connections, allowing administrators to analyze traffic patterns and troubleshoot any issues that may arise. The focus on IPsec within the command indicates that it targets a specific type of VPN, which is widely used for secure communications over public networks. In contrast, other commands like "get vpn status" may provide a more general view of the VPN infrastructure without detailed statistical counters, while "show vpn connections" and "list active vpns" might focus on currently established connections rather than the cumulative statistics across those connections. Thus, the first command is the most appropriate for obtaining a comprehensive view of the operational status of all active VPN tunnels in terms of traffic performance.
