Question 1

A system administrator wants to onboard switches to a greenfield site.

In this scenario, which three actions will accomplish this task?(Choose three.)

Answer Options
Correct Answer: B, C, D
Explanation

Forgreenfield onboarding, switches are newly deployed and must be claimed into Mist Cloud. Juniper Mist offers multiple claim options to simplify large-scale onboarding.

''You can claim switches using the device's QR claim code, by bulk importing from a sales order, or through API-based automation for large deployments. Each of these methods securely associates the devices to your organization in Mist Cloud.''

Option A:Incorrect --- serial number alone is not sufficient for claiming.

Option B:Correct--- claim codes (QR) uniquely identify switches.

Option C:Correct--- bulk claim from a sale order streamlines large deployments.

Option D:Correct--- APIs support automated claiming and provisioning workflows.

Option E:Incorrect --- MAC address alone cannot be used to claim devices.

Question 2

What are three ways that data is collected from the Mist backend?(Choose three.)

Answer Options
Correct Answer: A, B, C
Explanation

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.

Question 3

Which statement is correct about the VXLAN data plane?

Answer Options
Correct Answer: C
Explanation

VXLAN (Virtual Extensible LAN) uses an overlay encapsulation method to carry Layer-2 frames over an IP underlay. This functionality is part of the data plane, which is responsible for packet forwarding and encapsulation/decapsulation.

''In an EVPN-VXLAN fabric, the control plane (via BGP EVPN) learns and advertises MAC and IP information, while the data plane encapsulates and forwards traffic using VXLAN tunnels between VTEPs.''

Option A is incorrect: IP learning happens in the control plane, not the data plane.

Option B is incorrect: MAC advertisement is done in the control plane through EVPN route types.

Option D is incorrect: MAC learning is handled by EVPN control plane, not the VXLAN data plane.

Option C is correct: the VXLAN data plane encapsulates the traffic in UDP tunnels between VTEPs.

Question 4

When adopting your switches into theJuniper Mist Cloud, you notice that the status of the switches is''Unassigned.''

In this scenario, which additional step is required for the switches to show as''Connected''in the Juniper Mist dashboard?

Answer Options
Correct Answer: D
Explanation

When a switch is successfully onboarded into Mist Cloud but shows''Unassigned,''it means the device has been claimed into the organization but hasnot yet been assigned to a specific site.

''After claiming switches into an organization, you must assign each switch to a site for it to transition from Unassigned to Connected state and begin receiving configuration and telemetry updates.''

Option A:Incorrect --- rescanning is not needed once the device is claimed.

Option B:Incorrect --- reboots are unnecessary for assignment recognition.

Option C:Incorrect --- these commands are for connectivity troubleshooting, not site assignment.

Option D:Correct--- assigning each switch to itsintended siteenables full Mist management and connectivity state.

Question 5

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 movie?

Answer Options
Correct Answer: C
Explanation

In Juniper Mist campus fabric architectures, thelocation of the Layer 3 gateway (IRB interface)differentiatescentrally-routed bridging (CRB)fromedge-routed bridging (ERB):

InCRB, thegateway resides at the core layer--- routing occurs centrally, and access/distribution layers perform Layer 2 bridging.

InERB, thegateway 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 acore-distribution CRBto anERBmodel, thegateway moves from the distribution to the access layerin 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 movesfrom distribution to access (edge).

Option D:Incorrect --- this describes CRB, not ERB.
