In acore-distribution campus fabricmodel, the EVPN-VXLAN overlay is establishedonly between the core and distribution tiers. Theaccess switches are not part of the EVPN fabric; they connect upstream to distribution but do not run VXLAN tunnels.

“In the core-distribution campus fabric, only the core and distribution layers participate in the EVPN-VXLAN topology. The access layer connects to the distribution switches and forwards traffic but does not take part in the EVPN-VXLAN fabric.”

Option A:Correct — EVPN-VXLAN is built between core and distribution tiers.

Option B:Incorrect — both coreand distributionparticipate, not just core.

Option C:Incorrect — access switches are excluded from EVPN-VXLAN participation.

Option D:Correct — the access layer does not participate in EVPN-VXLAN.

Group-Based Policy (GBP)is a Juniper EVPN-VXLAN feature that enablesmicrosegmentationwithout requiring multiple VRFs or VLANs. It is implemented within Juniper Mist’sWired Assurance and Campus Fabricframeworks.

“GBP provides scalable, identity-based segmentation for campus fabrics and is supported on EX4100 and EX4400 Series switches operating in EVPN-VXLAN mode under Mist management.”

The feature requires hardware and software support forEVPN-VXLAN and GBP tagging, which is currently available on specific EX models managed by Mist Cloud.

Option A:Correct— GBP requires compatible access switches, specifically EX4100 and EX4400 models.

Option B:Incorrect — GBP is centrally managed through Mist Cloud, not configured per switch.

Option C:Incorrect — GBP is provisioned via Mist Cloud, not the CLI.

Option D:Incorrect — GBP is not supported onallEVPN-capable switches; only on defined platforms (EX4100/EX4400).
