Marvis is the Juniper Mist AI-driven Virtual Network Assistant (VNA). It is specifically designed to provide interactive troubleshooting through a natural language conversational interface. Administrators can ask questions like "Why is John's connection bad?" and Marvis uses its AI engine to analyze data, identify the root cause, and provide actionable insights. This functionality makes it the primary tool for AI-based interactive troubleshooting within the Mist platform, simplifying complex network operations and accelerating problem resolution.

B. Wireless Assurance: This is a cloud service that provides Service Level Expectations (SLEs) and network analytics, but Marvis is the interactive AI interface that uses this data.

C. Insights: This feature offers dashboards and reports for historical network analytics and trends, focusing on visibility rather than interactive, AI-driven troubleshooting.

D. Site Configuration: This is the administrative section of the Mist UI used for setting up and managing network policies, WLANs, and device settings, not for troubleshooting.
