A company is deploying a new wired network and wants to ensure that all wired clients are automatically identified and their location tracked for security and compliance purposes. The network uses EX switches managed by Mist. Which set of features should the administrator enable?

Configure 802.1X authentication on all ports to identify clients.

Enable DHCP snooping and IP Source Guard to track client IP addresses.

Enable LLDP and CDP on all switch ports to discover neighboring devices.

Enable the Mist 'Wired Client Visibility' feature and ensure the switch is configured to report client information to the Mist cloud.

A network engineer is troubleshooting a connectivity issue in a wiring closet. The Mist portal shows that a switch port is 'up' but the connected device is not receiving an IP address. The engineer suspects a cabling issue. Which Mist feature should the engineer use to verify the physical link and cabling?

Review the 'Port Statistics' to see if there are any CRC errors or drops.

Use the 'Topology View' to see if the switch is correctly connected to the upstream switch.

Check the 'Link Status' page to see if the port is administratively up and the link is negotiated.

Use the 'Cable Test' feature in the Mist portal to perform a TDR test on the port.

A network administrator notices that several PoE-powered IP cameras are intermittently losing connectivity. The Mist portal shows that the switch's PoE power budget is consistently at 95% utilization. What should the administrator do first to address the issue?

Review the PoE usage per port in the Mist portal and identify any non-critical devices that can be deprioritized or disconnected.

Increase the switch's PoE power budget by configuring a higher power limit in the switch settings.

Disable PoE on all ports and re-enable it one by one to identify the faulty camera.

Replace the IP cameras with lower-power models.

How does Mist AI contribute to anomaly detection in wired networks?

By learning normal switch behavior and flagging deviations

By comparing switch configurations to a fixed set of rules

By requiring administrators to manually set thresholds for every metric

By analyzing only the switch's syslog messages

Which benefit is most directly associated with Juniper Mist Wired Assurance?

Guaranteed 100% network uptime for all connected devices
