A network administrator notices that users at a branch office are experiencing slow application performance. The administrator wants to determine whether the issue is caused by WAN link latency, packet loss, or the application server itself. Which Mist WAN Assurance dashboard or tool should be used first to isolate the problem?

WAN Edge dashboard to view link status and utilization for the branch's uplinks.

Application Performance dashboard to see latency, jitter, and loss for the specific application traffic.

Event logs to check for interface flaps or configuration changes on the SRX.

Marvis Actions to get AI-driven recommendations for fixing the application.

A user at a branch office reports that a specific application is slow, but other applications work fine. The WAN link is healthy, and the application server is in the data center. The administrator wants to see if the issue is specific to the application or if it is a general WAN problem. Which Mist tool should be used to get a detailed view of the application's performance?

Application Performance dashboard

What is the primary method for configuring WAN edge devices in Juniper Mist?

Using a third-party network management system to push CLI commands

Editing the device's configuration file directly in the Mist portal

Using templates that define configuration for interfaces, routing, and VPNs

Configuring each device individually through its local web interface

A network engineer is deploying a new SRX320 at a remote retail site. The device is physically installed and has out-of-band management access to the internet. The engineer wants to onboard the device into Juniper Mist so it can be managed centrally. What is the required first step to complete the onboarding process?

Upload a configuration file to the device via USB that contains the Mist organization ID and API token.

Manually configure the device's management IP address to match the Mist cloud's subnet.

Connect the device to the Mist cloud using a site-to-site VPN to the nearest Mist edge PoP.

Generate an activation code in the Mist portal and enter it on the device via the CLI.

In Mist WAN policies, what is the role of 'application' as a match criterion?

To define the software version of the WAN edge device

To specify the physical port used by the application

To identify specific applications for traffic steering or prioritization

To determine the geographic location of the user
