The Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum identifies Real User Tests (RUM) as the primary method for capturing actual browser-based interactions. While synthetic tests provide proactive baselines, Real user tests (Option C) provide visibility into the "lived experience" of an employee as they navigate corporate websites and SaaS platforms.
Real user tests utilize a lightweight browser extension (available for Chrome, Edge, and Safari) that is part of the Endpoint Agent deployment. When a user visits a domain defined in a
"Monitored Domain Set," the extension automatically begins recording performance metrics. This includes the time spent on each page, DNS resolution time, and a full browser waterfall of every object (images, scripts, CSS) loaded during the session. Crucially, it calculates an "Experience Score" for each session, allowing IT teams to identify if a user's frustration is caused by slow page rendering or underlying network issues.
