JN0-460 Exam Dumps - Juniper JNCIS-MistAI Questions and Answers

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.

TheAlerts Configurationsection in the Mist dashboard allows administrators to definenotification rules and recipientsfor various network events, including switch issues, site-level incidents, and SLE threshold violations. Notifications can be sent viaemail, 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.

According to the Juniper Mist dashboard's firmware management interface shown in the exhibit, several key details of the switch upgrade process are visible. The "Upgrade switch firmware" dialog box is a standard component of Juniper Mist Wired Assurance used to manage Junos OS updates across the fabric.

The correct statement is that the switch will reboot after the upgrade. This is explicitly confirmed by the checkbox labeled "Reboot switch after image copy," which is currently selected in the exhibit. In Juniper's cloud-managed workflow, once the new software image is successfully transferred from the Mist cloud to the switch's local storage, the system requires a reboot to initialize the new Junos OS kernel and complete the installation process5. While some platforms support non-disruptive upgrades, the standard procedure for EX-series switches in a standalone or Virtual Chassis configuration typically involves a scheduled reboot to ensure the new version is correctly applied.

The other options are incorrect based on the visual evidence provided in the exhibit.

Option A: The exhibit clearly identifies the "Switch Model" as an EX2300-C-12P (the 'P' designating PoE support), not an EX2300-C-12T88.

Option C: The dialog box explicitly states "Total Switches selected to upgrade: 1," confirming this is a single-device operation rather than a bulk upgrade.

Option D: The "Upgrade to Version" field is set to 19.3R1.8, which indicates the target version, not the previous version10101010.

By providing these granular controls, Juniper Mist allows administrators to maintain strict version compliance across the site while choosing whether to immediately reboot or stage the image for a later maintenance window.

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.

Route targets (RTs)are extended BGP communities used inMultiprotocol BGP (MP-BGP)forEVPN-VXLANto control route import/export between VRFs.

“A route target identifies the VRF instances that should import or export specific MP-BGP routes. It enables the association of EVPN routes with particular VRFs in multi-tenant environments.”

Option A:Incorrect — EVPN family support is identified through BGP capabilities, not RTs.

Option B:Incorrect — that’s handled by BGP EVPN negotiation, not route targets.

Option C:Correct— route targets definewhich VRFs import/export BGP routes.

Option D:Incorrect — RTs can be manually configured and reused where necessary.
