A network administrator needs to automate the process of starting a packet capture on multiple APs simultaneously to troubleshoot a site-wide issue. The administrator wants to use a script to initiate these captures. What is the recommended method to achieve this?

Use the Mist portal to start a capture on the site, which automatically captures on all APs.

Use the Juniper Mist API to start a capture on each AP by specifying the site and AP ID in the API call.

Use a third-party network monitoring tool that integrates with Mist to start captures.

SSH into each AP and run the capture command manually.

How can a network administrator start a packet capture on a Juniper Mist-managed device?

By SSHing into the device and running the 'monitor traffic' command

By using the Mist portal's 'Packet Capture' feature or the Mist API

By configuring a syslog server to capture packets automatically

By sending a special SNMP trap to the device

What is the correct way to export a packet capture from the Mist portal for external analysis?

Use the Mist API to stream the capture to a local server in real time

Copy the capture data from the Mist UI and paste it into a text editor

Download the capture file in PCAP format from the Mist portal

Email the capture file to yourself from the Mist portal

A network administrator has just completed a packet capture on an AP to investigate a client authentication failure. In the Mist portal, the administrator is viewing the capture results. What is the most efficient way to quickly identify the authentication failure in the captured packets?

Download the PCAP file and open it in a text editor to search for the word 'failure'.

Use the Mist portal's built-in packet viewer to apply a display filter for EAP or RADIUS protocols.

Look at the Mist portal's event log for the AP instead of the capture.

Export the capture to a CSV file and sort by the protocol column.

Which of the following is a valid method to start a packet capture on a Juniper Mist-managed device?

Using the Mist API to initiate a capture session

Using the Mist mobile app to start a capture on any device

Using the device's local web interface

Using a CLI command on the device
