Marvis is Juniper's Virtual Network Assistant (VNA) that leverages AI to provide natural language queries, anomaly detection, and proactive troubleshooting across wireless, wired, and WAN networks.
"Marvis, the AI-driven Virtual Network Assistant, requires a Virtual Network Assistant subscription. The subscription enables Marvis to provide insights, recommendations, and natural language queries for Mist- managed networks." Option A (Access Assurance) is related to NAC/802.1X enforcement.
Option B (IoT Assurance) applies to profiling and securing IoT devices.
Option D (Wired Assurance) enables switch telemetry, onboarding, and assurance, but does not unlock Marvis.
Option C (Virtual Network Assistant) is correct - this subscription is required to enable Marvis AI.

WhenMarvis Actionsdisplay "AI Validated," it indicates the issue was detected earlier but is nowresolved.
Marvis automatically validates remediation and marks the action closed once the anomaly clears.

In anEVPN-VXLAN fabric, thecontrol planeoperates overBGP EVPNand is responsible for distributing endpoint reachability information (MAC and IP) among VTEPs. Thedata plane, by contrast, performs encapsulation and forwarding.
"The EVPN control plane uses BGP to exchange MAC and IP address reachability information between VTEPs, enabling efficient forwarding and loop prevention without relying on flood-and-learn behavior." Option A:Incorrect - encapsulation occurs in thedata plane, not the control plane.
Option B:Correct - the control plane distributesMAC-to-VTEP mappings.
Option C:Correct - the control plane also distributesIP-to-MAC associations(Type 2 and Type 5 EVPN routes).
Option D:Incorrect - the control plane does not alter packet headers.

In Juniper Mist,Greenfield adoptionapplies to new, cloud-ready switches (such as EX4100, EX4400, and QFX series) using aclaim or activation codeto securely connect to the Mist cloud.
Brownfield adoption, however, supports switches already deployed or not factory-fresh. These are manually onboarded by configuring outbound management connectivity and adopting them through the Mist portal.
This distinction enables both new and legacy EX/QFX environments to be cloud-managed under Wired Assurance.

Juniper Mist uses open, cloud-native APIs to providereal-time telemetry and integration.
Data is collected and streamed from the backend using:
RESTful APIs- for configuration, automation, and reporting.
Webhooks- to push events, alerts, or SLE changes to third-party systems.
