Which metrics does the ZDX Web Probe provide?

The ZDX Web Probe provides critical performance metrics that help analyze the web experience from the end user's perspective. The correct choice highlights specific metrics: Page Fetch Time, DNS Time, Server Response Time, and Availability.

Page Fetch Time measures how long it takes to retrieve a web page, which is essential for understanding user experience. DNS Time indicates how long it takes to resolve a domain name into an IP address, a crucial step before any data can be fetched. Server Response Time refers to the time the server takes to respond to a request after receiving it, which directly influences the overall user experience. Finally, Availability checks whether the web service is accessible or not, forming a foundation for assessing web performance.

These metrics collectively provide a holistic view of how users experience web applications, making this choice particularly relevant for monitoring and improving web-based services. The focus on actual user experience aligns with Zscaler's goals of enhancing security and performance in a cloud-first world.
