To monitor a Versa CPE interface's live data, you would use the Versa Director. The Versa Director provides a comprehensive interface for real-time monitoring and management of SD-WAN infrastructure, including the visualization of traffic flows and performance metrics. Through Versa Director, network operators can gain insights into transmission data for all traffic or SD-WAN-specific traffic, updated every few seconds, and detailed information about interface statistics.

In a Versa Secure SD-WAN deployment, the following statements about traffic forwarding are accurate:
* By default, all data traffic is forwarded on IPSec tunnels (Answer A): Versa SD-WAN solutions typically encrypt all data traffic by default using IPSec tunnels. This security measure ensures that data remains protected while transiting over the public or private WAN, safeguarding against eavesdropping and data theft.
* By default, all control traffic is forwarded on IPSec tunnels (Answer B): Similarly, control traffic in Versa SD-WAN is also encrypted and sent through IPSec tunnels. This practice secures the signaling and management traffic, preventing potential attacks that could target the network's control plane.
Options C (By default, all data traffic is forwarded on unencrypted tunnels) and D (By default, all control traffic is forwarded on unencrypted tunnels) are incorrect as they contradict the security-oriented design of Versa SD-WAN, which emphasizes the encryption of both data and control traffic by default.
