Which statement is correct regarding the Mist UI?
The Mist UI (User Interface) is Juniper's cloud-based management platform used to manage both wired and wireless devices, including EX, QFX, and SRX platforms.
It provides centralized visibility, configuration, analytics, and AI-driven insights for the entire enterprise network infrastructure.
Within Wired Assurance, the Mist UI enables device claiming, switch templates, configuration management, and SLE monitoring.
Which two statements are correct about the EVPN-VXLAN control plane? (Choose two.)
In an EVPN-VXLAN fabric, the control plane operates over BGP EVPN and is responsible for distributing endpoint reachability information (MAC and IP) among VTEPs. The data 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 the data plane, not the control plane.
Option B: Correct --- the control plane distributes MAC-to-VTEP mappings.
Option C: Correct --- the control plane also distributes IP-to-MAC associations (Type 2 and Type 5 EVPN routes).
Option D: Incorrect --- the control plane does not alter packet headers.

Which three switch testing tools are available when using Wired Assurance? (Choose three.)
According to Juniper Mist Wired Assurance documentation, three built-in diagnostic tools available for testing switch functionality are Bounce Port, Ping, and Cable Test.
Bounce Port allows you to disable and re-enable a port to reset connectivity.
Ping verifies Layer 3 reachability between the switch and target IPs.
Cable Test performs diagnostics to detect wiring faults, impedance mismatches, or cable lengths.
These tools are accessed directly from the Switch Testing Tools section in the Mist dashboard and are available for EX Series and QFX Series switches onboarded to the Mist cloud.
Which campus fabric architecture supports Layer 3 gateways at the distribution layer?
In Juniper's campus fabric architectures, the location of the Layer 3 gateway (IRB) differentiates between CRB and ERB models:
Centrally-Routed Bridging (CRB): L3 gateways are placed at the core layer.
Edge-Routed Bridging (ERB): L3 gateways are placed at the distribution layer, closer to the edge.
''In the ERB model, Layer 2 gateways are deployed at the access layer, and Layer 3 gateways are deployed at the distribution layer.''
Option A (CRB): Incorrect --- L3 is at the core, not distribution.
Option B (IP Clos): Incorrect --- in 3-stage Clos, L3 is pushed to the access layer.
Option D (EVPN multihoming): Incorrect --- this is about redundancy, not gateway placement.
Option C (ERB): Correct --- L3 gateways sit at the distribution layer in the ERB architecture.

What are three ways that data is collected from the Mist backend? (Choose three.)
Juniper Mist uses open, cloud-native APIs to provide real-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.
WebSockets -- for real-time updates between Mist cloud and clients (dashboards or automation tools).
These methods support seamless integration and programmability for both Wired and Wireless Assurance.
