Which requirements must be met to monitor Zoom or Teams call quality statistics using ZDX?

To monitor Zoom or Teams call quality statistics using ZDX, it is crucial that traffic can traverse via ZIA (Zscaler Internet Access) or directly, and that the corresponding tenants are added under Applications. This flexibility allows for accurate monitoring of call quality regardless of how the traffic is being routed.

Having traffic pass through ZIA offers the advantage of comprehensive visibility into the user experience and performance metrics, as ZDX can analyze and provide insights based on the traffic data it collects. Additionally, adding the specific tenants in the Applications section is essential for ZDX to recognize and monitor the calls properly, ensuring it can assess the relevant quality statistics effectively.

The other options do not align with the requirements for effectively monitoring call quality. For instance, limiting monitoring to the same network is restrictive and would not allow comprehensive insights from different sources or varying network conditions. Similarly, stating that monitoring only works with ZIA rules or requires local server installation imposes unnecessary limitations that conflict with the way ZDX is designed to operate efficiently across different setups and configurations.
