EVPN, when used with VXLAN, leverages BGP MPLS/VXLAN control plane mechanisms. To prevent overlapping IP prefixes between different tenants or sites, EVPN uses a Route Distinguisher (RD).

''In EVPN-VXLAN, the route distinguisher (RD) makes routes unique when overlapping IP prefixes or MAC addresses are advertised between multiple tenants or sites.''

Option A (designated forwarder) applies to multi-homing in EVPN, not prefix uniqueness.

Option B (Layer 2 gateway) does not prevent IP overlap; it bridges VLANs.

Option D (ESI) is used for identifying multi-homed Ethernet segments, not to differentiate overlapping subnets.

Option C (Route Distinguisher) is correct, as it uniquely identifies routes even if the IP addresses are the same across sites.

Dynamic Packet Capture (DPC) requires no manual setup.

It is automatically linked to relevant client events on the Insights page, enabling fast root-cause analysis without extra configuration.

The Alerts Configuration section in the Mist dashboard allows administrators to define notification rules and recipients for various network events, including switch issues, site-level incidents, and SLE threshold violations. Notifications can be sent via email, webhook, or third-party integrations.

''Use the Alerts Configuration page to enable alerts for specific device events, assign severity levels, and define e-mail or webhook recipients for switch and site notifications.''

Option A (Marvis conversational interface): Used for querying issues via AI, not for email alerts.

Option B (Wired SLEs): Provides analytics and thresholds but does not manage notifications.

Option D (Marvis Actions): Offers suggested remediation steps, not alert setup.

Option C (Alerts Configuration): Correct --- this is where email notifications are configured.

Juniper Mist Wired Assurance -- Alerts and Reporting

Juniper Mist uses open, cloud-native APIs to provide real-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.

WebSockets -- for real-time updates between Mist cloud and clients (dashboards or automation tools).

These methods support seamless integration and programmability for both Wired and Wireless Assurance.

According to the Juniper 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 as configuring DNS servers or defining GBP tags are not part of the campus fabric deployment workflow in Mist Wired; they are optional or separate configurations outside the main deployment flow.

Within Mist Insights, Client Events show state transitions such as reassociation and IP-level issues like DHCP Denied.

These help correlate connectivity issues across wired or wireless edge connections.

An organization-level configuration template can only be applied to site groups, not to individual sites.

Therefore, a single site such as Site A cannot be directly specified inside an org-level template.

===========

For Juniper cloud-ready EX Series switches (EX2300, EX3400, EX4100, EX4400, etc.) to successfully onboard to the Juniper Mist Cloud, specific connectivity requirements must be met:

''Cloud-managed EX switches require outbound connectivity to the Mist Cloud on TCP ports 2200 or 443. Switches must also have access to DNS services to resolve cloud service URLs during onboarding.''

Option A: Incorrect --- minimum version depends on switch model; older models may onboard with earlier releases (e.g., 20.x, 21.x).

Option B: Correct --- outbound TCP 2200 or 443 connectivity is required for cloud registration.

Option C: Incorrect --- switches connect directly to Mist Cloud, not the Agile Licensing Portal.

Option D: Correct --- DNS resolution is mandatory for discovering Mist Cloud endpoints.
