ZDX Advanced client performance uses live telemetry from real user sessions to measure the experience of internet and private applications. Synthetic probes are useful for availability and path testing, but client performance is gathered by continuously observing active user sessions, endpoint condition, and traffic behavior. Option B (By constantly analyzing live user sessions to both Internet and Private applications and measuring the performance of those sessions) is correct because ZDX Advanced client performance is based on live session analysis.
Why the other options are incorrect:
A. By generating synthetic transactions to designated Internet and Private applications every 5 minutes and measuring the performance of those sessions: Synthetic transactions are scheduled probes that test applications independently of live user sessions.
C. By using AI predictive analysis ZDX can extrapolate near-term client performance based upon recent past data observed: AI prediction would forecast likely performance, but the tested ZDX function measures actual client/application sessions.
D. By constantly analyzing live user sessions to critical SaaS applications and measuring the performance of those sessions: SaaS applications are handled by ZIA controls such as URL Filtering, Cloud App Control, and DLP, not by ZPA App Connectors.
