Pass the Juniper JNCIS-MistAI JN0-451 Questions and answers with ValidTests

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.

According to the Virtual Network Assistant | Juniper Networks US document, Asymmetry Downlink is a classifier under the Coverage SLE that tracks an AP that transmits at a lower data rate than a connected client. This can indicate poor coverage or interference issues that affect downlink performance.

As part of the Throughput SLE in the Mist UI, the Coverage classifier indicates the signal strength of the client.

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.

According to the VLANs (Static & Dynamic) - Mist document3, you can define VLANs as untagged, tagged, or using VLAN pooling in the WLAN settings in the Juniper Mist UI. A WLAN is a wireless network that defines parameters such as SSID, security type, and VLAN.

According to the JNCIS-MistAI Certification page2, two Mist APs that would be used for BLE location are AP33 and AP43. These are the only two models that support vBLE array technology, which enables accurate location services without physical beacons.

The Wireless Assurance SLE that provides information on whether a user is able to associate to the WLAN is Successful Connect. So the correct answer is A. Successful Connect.

When deploying three WLAN 2.4 GHz networks in your US-based site while ensuring that each network frequency is unique and does not overlap with other frequency channels, you should use OFDM channels 1, 6 and 11. So the correct answers are B.1, D.6, and A.11.
