What is meant when aMarvis Actionis shown as ??AI Validated???
Correct Answer:
D
You must provide physical connectivity between the core and access devices.
Which step of the campus fabric deployment process would allow you to accomplish this task?
Correct Answer:
A
In theCampus Fabric Deployment Wizard, the first step is defining thetopology type(3-stage or 5-stage IP Clos) and mapping thephysical connectionsbetween devices (core, distribution, and access).
??The first step in the campus fabric deployment process is to define the topology and identify physical connections between devices. This ensures correct port mapping between core, distribution, and access tiers.??
Option A:Correct— topology definition and physical connectivity mapping occur in the initial step.
Option B:Incorrect — the underlay network configuration happens after topology definition.
Option C:Incorrect — overlay configuration handles EVPN/VXLAN and routing setup, not physical cabling.
Option D:Incorrect — applying intent finalizes the deployment but does not define connectivity.

You want a Juniper cloud-ready switch to connect to theJuniper Mist Cloud. In this scenario, which two statements are correct?(Choose two.)
Correct Answer:
BD
A switch is claimed in a Mist organization using the activation code.
What are two possible device states that the switch will have in this scenario?(Choose two.)
Correct Answer:
AD
When a switch is claimed into a Mist organization, it appears in one of several states depending on connectivity and site assignment.
??After claiming, switches initially appear asUnassignedif they are not yet linked to a site. Once online and connected to Mist Cloud, they transition toConnectedstatus and begin receiving configurations and telemetry.??
Option A (Connected):Correct— indicates the switch is online and communicating with Mist Cloud.
Option B (Inactive):Incorrect — not a valid device state in Mist.
Option C (Active):Incorrect — ??Active?? is not a device state label in Mist.
Option D (Unassigned):Correct— indicates the switch has been claimed but not yet assigned to a site.

When is a virtual routing and forwarding (VRF) instance typically used?
Correct Answer:
B
According to Juniper Networks' documentation on campus fabric and EVPN-VXLAN architectures, aVirtual Routing and Forwarding (VRF)instance—conceptually referred to within the Junos OS as arouting instance—is typically used to providemacro-segmentationby logically separating a single physical network into multiple, isolated virtual networks.2 In the context of a modern campus fabric managed by Juniper Mist, VRFs allow network administrators to create distinct routing domains that maintain their own independent routing and forwarding tables.3
This separation is essential formultitenancy and security.4 For example, an organization might use one VRF for "Corporate_IT" and another for "Guest_WiFi" or "IoT_Devices". Because each VRF operates with its own routing table, traffic belonging to one instance is completely isolated from traffic in another by default; packets cannot travel between VRFs unless an administrator explicitly configures "route leaking" or directs the traffic through a stateful firewall for security inspection. This architectural approach also permits the use ofoverlapping IP address spaces, as the routing decisions for one tenant do not interfere with the address entries of another.5
In a Juniper Mist-driven campus fabric (such as Core-Distribution or IP Clos), the Mist portal streamlines the creation of these VRF instances as part of the fabric workflow.6 Once a VRF is created, specific VLANs (and their corresponding IRB interfaces) are assigned to it, ensuring that Layer 3 gateways are placed in the correct logical domain. While theunderlay network(Option D) is responsible for providing the physical reachability (loopback to loopback) between switches using a protocol like eBGP, theoverlay networkleverages VRFs to deliver the actual isolated user services.
