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.

Under which hierarchy level would you create a new site configuration?
In the Juniper Mist UI, a site is created under the location hierarchy.
Sites represent logical or physical locations grouping wired and wireless devices for unified management.

You are asked to forward event messages from Mist to an external log collector.
Which feature enables this capability?
Syslog is the standard method for exporting Mist AI event and telemetry messages to third-party collectors.
It supports both UDP and TCP delivery for centralized log correlation.

You must move from a campus fabric core-distribution centrally-routed bridging (CRB) network to an edge-routed bridging (ERB) network.
In this scenario, where does the gateway for the network move?
In Juniper Mist campus fabric architectures, the location of the Layer 3 gateway (IRB interface) differentiates centrally-routed bridging (CRB) from edge-routed bridging (ERB):
In CRB, the gateway resides at the core layer --- routing occurs centrally, and access/distribution layers perform Layer 2 bridging.
In ERB, the gateway moves to the edge (distribution layer), enabling routing to occur closer to endpoints, improving performance and scalability.
''In a centrally-routed bridging (CRB) topology, Layer 3 gateways reside at the core. When transitioning to an edge-routed bridging (ERB) design, the Layer 3 gateways are moved to the distribution layer, closer to the access switches and clients.''
Therefore, when moving from a core-distribution CRB to an ERB model, the gateway moves from the distribution to the access layer in campus terms (edge = access).
Option A: Incorrect --- ERB gateways are not at the distribution layer only.
Option B: Incorrect --- opposite direction.
Option C: Correct --- the gateway moves from distribution to access (edge).
Option D: Incorrect --- this describes CRB, not ERB.

What is meant when a Marvis Action is shown as ''AI Validated''?
When Marvis Actions display ''AI Validated,'' it indicates the issue was detected earlier but is now resolved.
Marvis automatically validates remediation and marks the action closed once the anomaly clears.
