InJuniper Mist Wired Assurance, SLEs (Service Level Expectations) measure key performance indicators for wired network quality.Throughput SLEmonitorsdata transfer quality, includinglatency, jitter, and packet loss, which directly impact real-time applications such as voice or video.

“The Throughput SLE provides visibility into end-to-end network performance by tracking latency, jitter, and packet loss, helping identify congestion or quality issues across wired connections.”

Option A (Throughput):Correct— this SLE includes jitter measurement.

Option B (Successful Connect):Tracks client connection success rate, not jitter.

Option C (Capacity):Monitors link utilization and load, not jitter.

Option D (Switch Health):Monitors device hardware and software health, not traffic performance.

According to theJuniper Mist AI for Wired – Campus Fabric IP Clos Deployment Workflow, deploying a campus fabric involves a defined sequence of planning and configuration steps within the Mist Cloud interface. The key stages include:

“To deploy a campus fabric, you must first define the topology type, identify the physical connections between devices, and define the networks of interest that will be extended across the fabric.”

Breaking this down:

Choose the topology (D):Selecting the correct fabric type (3-Stage or 5-Stage IP Clos) determines how access, distribution, and core switches will interconnect.

Define the physical connections (A):This step involves specifying the uplink and downlink relationships between switches so that Mist can auto-generate EVPN-VXLAN and routing configurations.

Define the networks of interest (B):These are the VLANs and subnets that need to be extended across the fabric for user and device connectivity.

Steps such asconfiguring DNS serversordefining GBP tagsarenot part of the campus fabric deployment workflowin Mist Wired; they are optional or separate configurations outside the main deployment flow.

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.

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.

Comprehensive and Detailed Explanation From Exact Extract:

InEVPN-VXLANarchitectures, theVXLAN Tunnel Endpoint (VTEP)is the logical interface responsible for encapsulating and de-encapsulating Layer 2 Ethernet frames into VXLAN packets.

Each participating switch — typically the access or distribution node — hosts aVTEPthat maps local VLANs to VXLAN Network Identifiers (VNIs).

When a packet leaves a local VLAN, the VTEP encapsulates it in a VXLAN header and routes it through the underlay IP fabric.

When received at the destination VTEP, the frame is de-encapsulated and delivered to the appropriate local VLAN.

“VTEPs in an EVPN-VXLAN campus fabric perform MAC-to-VNI mapping and encapsulate/decapsulate traffic between virtualized network segments, allowing seamless Layer 2 and Layer 3 connectivity across an IP underlay.”
