Juniper JN0-451 - Mist AI - Specialist (JNCIS-MistAI)

 According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, RF templates are assigned to sites, which are logical groupings of devices based on physical location or other criteria. RF templates allow you to configure RF parameters such as channel width, transmit power, and data rates for multiple devices at once.

According to the exhibit, the organization has a total of two licenses for Marvis wireless, and one of them is in use. Therefore, the organization has one available license and one used license for Marvis wireless.

According to Coverage SLE, Asymmetry Downlink classifier tracks a client that transmits at lower data rate than AP to which it is connected.So the correct answer is A.Asymmetry Downlink

Referring to the exhibit and considering that it is in the USA, the WLAN with SSID Eero1234 is not configured to industry best practices while the WLAN with SSID NETGEAR24 is configured to industry best practices.

The AI VALIDATED status update means that the issue was opened and Marvis confirms it has been closed.

According to the Marvis Virtual Network Assistant Datasheet1, the AI-VALIDATED status update means that the issue was opened and Marvis confirms it has been closed. This status indicates that Marvis has verified that the issue is no longer present and the root cause has been resolved.

According to the Marvis - Mist document, unhappy clients is a query that can be used in Marvis to identify users who cannot connect to the network. Unhappy clients shows a list of clients who have experienced poor service level expectations (SLEs) such as connection failures, coverage issues, or low throughput.

Once a client discovers an access point, the correct order of steps for successful 802.1X authentication is Open System Authentication -> Association -> 802.1X Authentication. So the correct answer is D.Open System Authentication -> Association -> 802.1X Authentication.

In the IEEE 802.1X authentication process, the AP acts as an authenticator.

According to the Lecture 5 - Security - Part 1 document, the AP’s role in the IEEE 802.1X authentication process is to act as an authenticator. This means that the AP acts as a gatekeeper between the client device (supplicant) and the RADIUS server (authentication server). The AP forwards authentication messages between the supplicant and the server and grants or denies network access based on the server’s response.
