Marvis is Juniper's AI-driven Virtual Network Assistant (VNA) designed to simplify network operations. A core feature is its conversational interface, which uses Natural Language Processing (NLP) to allow administrators to ask plain-language questions about network performance and user experiences. Additionally, Marvis functions as a proactive monitoring tool through its "Marvis Actions" dashboard. This feature automatically detects network anomalies, identifies the root cause of issues before they significantly impact users, and provides actionable recommendations for resolution.

A. The Juniper Mist cloud portal is the main configuration tool for network policies, templates, and device settings; Marvis is primarily for analytics and troubleshooting.

C. While the Mist platform has extensive reporting capabilities, Marvis's primary function is proactive issue detection and conversational queries, not generating and sending custom reports.

3. Juniper Networks Data Sheet, "Marvis Virtual Network Assistant": This document outlines the core capabilities, stating, "Proactively find and fix network problems before users know they exist" and describes the "Natural Language Processing (NLP) based conversational interface."
