A retail company manages 200 Juniper Mist APs across multiple stores. A user at Store 12 reports that their laptop intermittently drops off the Wi-Fi network every few minutes. The network engineer wants to capture traffic only from that specific client's MAC address to diagnose the issue. What is the most efficient way to initiate this capture in the Mist portal?

Navigate to the AP's details page, start a capture on the AP's uplink interface, and set the duration to 10 minutes.

Use the Mist API to start a capture on the site, specifying the SSID and a packet size of 512 bytes.

Navigate to the client's details page in the Mist portal and start a packet capture from that page, applying a filter for the client's MAC address.

SSH into the AP and run the built-in 'monitor traffic' command with a MAC filter.

A network engineer has completed a 10-minute packet capture on an AP to investigate a DHCP issue. The engineer needs to share the raw capture data with a colleague who uses Wireshark for analysis. What is the correct way to obtain the capture file for external analysis?

In the Mist portal, navigate to the capture session and click the download button to save the file in PCAP format.

Copy the capture data from the Mist UI's built-in packet viewer and paste it into a text file for the colleague.

Use the Mist API to retrieve the capture in CSV format for import into Wireshark.

SSH to the AP and copy the capture file from the /var/tmp directory.

Which parameter can be configured when setting up a packet capture in Juniper Mist?

The encryption algorithm for the capture

The number of packets to capture

The destination IP address for the capture file

What is the primary purpose of initiating a packet capture on a Juniper Mist-managed device?

To replace the need for other monitoring tools by providing continuous real-time analytics

To capture and analyze live traffic for troubleshooting issues such as connectivity or authentication failures

To permanently store all network traffic for compliance auditing

To automatically block malicious traffic based on captured packets

How can a network administrator view the results of a packet capture in the Mist portal?

By checking the device's local logs

By using a third-party packet analyzer to connect directly to the device

By navigating to the 'Packet Capture' section and selecting the completed capture

By accessing the capture file via FTP from the device
