JN0-460 Exam Dumps : JNCIS-MistAI-Wired

When deployingJuniper Mist Wired AssuranceinManaged mode, switches are fully integrated with Mist Cloud for configuration, monitoring, and AI-driven operations. Managed mode providescomplete cloud-based management, meaning Mist AI handles configuration, templates, telemetry, and SLE tracking.

“In Managed mode, the switch configuration is fully managed by Mist Cloud. Administrators configure switches, templates, and policies directly through the Mist dashboard. A valid Wired Assurance subscription is required for Managed mode operation.”

Option A:Incorrect — the “Monitor Only” mode is read-only, not Managed.

Option B:Correct— Managed mode requires aWired Assurance subscription.

Option C:Incorrect — subscriptions are mandatory for Mist-managed devices.

Option D:Correct— in Managed mode,all supported EX switches are fully managed by Mist AI, including configuration and telemetry.

During campus fabric deploymentin Mist AI, switches are onboarded usingclaim codesand must beassigned to the correct siteandonlineso that Mist can push configurations and validate connectivity.

“All switches to be included in a campus fabric must be claimed, online, and assigned to the target site before launching the Campus Fabric wizard. Mist Cloud automatically discovers their roles and builds the topology.”

Option A:Incorrect — switches must be site-assigned before fabric creation.

Option B:Correct— switches must beonlineto receive configurations from Mist.

Option C:Incorrect — offline devices cannot be configured or validated in the fabric wizard.

Option D:Correct— switches must beassigned to the correct sitefor topology creation.

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.
