JN0-451 Juniper Mist AI - Specialist (JNCIS-MistAI) Free Practice Exam Questions (2025 Updated)

According to the Wi-Fi - Radio Modulation - TutorialsPoint document1, 64 QAM is a modulation method that will result in the highest theoretical data rates among the given options. 64 QAM uses both phase and amplitude modulation to encode six bits of information into each transmitted symbol. It can achieve up to 54 Mbps in the 802.11a and g systems.

The Compatible WLAN data rate setting is required for legacy 2.4 GHz scanners to connect to the WLAN.

According to the Data Rates - Mist document4, the WLAN data rate setting that is required for legacy 2.4 GHz scanners to connect to the WLAN is Compatible. This setting enables all data rates from 1 Mbps to 54 Mbps for both 2.4 GHz and 5 GHz bands. This setting is recommended for legacy devices that need low data rates to connect.

According to the Location - how it works - Mist document1, a Mist AP actually begins transmitting BLE when it is placed on a floor plan. This is because the Mist cloud uses the floor plan information to calculate the optimal BLE transmission pattern for each AP.

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 Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, there are two ways to access Marvis, which is a virtual network assistant that provides insights and troubleshooting for wireless networks:

Use the conversational assistant, which allows you to ask natural language questions and get answers from Marvis.

Use Actions, which are predefined queries that you can select from a list and get results from Marvis.

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 Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, a config template is a configuration object that can be used to apply consistent WxLAN and WLAN policies across all sites within the same organization. A config template can be applied to a site group, which is a collection of sites that share common attributes.

References: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-2/config-guide/b_wl_17_2_cg/config_templates.html

According to the Mist documentation1, WLANs are wireless networks that can be configured with different settings such as SSID, security, encryption, authentication, etc. WLANs can be created and managed at different levels of hierarchy in the Mist cloud.

The site group level allows you to create and apply WLANs to a group of sites that share common characteristics or requirements2. This helps you to simplify and standardize your WLAN configuration across multiple sites.

The site level allows you to create and manage WLANs for a specific site that may have unique needs or preferences1. This gives you more flexibility and granularity for your WLAN configuration at each site.

According to the Create a Mist Account and Organization - Mist document1, two fields that are required when creating a new site are:

Site name, which is a unique identifier for the site within the organization.

Time zone, which is used to display the correct time for events and reports related to the site.

According to the Mist documentation1, asset tracking is a service that allows you to find key assets and people with detailed analytics based on their location using Mist-supported third-party BLE beacons. To enable asset tracking, you need to configure both the BLE beacons and the Mist cloud settings.

The Show assets check box is a setting in Live View that allows you to display or hide the assets on the floor plan2. If this check box is not selected, you will not be able to see the third-party beacons on Live View.

The Locate this Client as an Asset check box is a setting at the BLE client level that allows you to treat a BLE client as an asset for location purposes3. If this check box is not selected, you will not be able to track the BLE client as an asset.

According to Wikipedia1, 802.1X is an IEEE Standard for port-based network access control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN using Extensible Authentication Protocol (EAP) over wired IEEE 802 networks and over 802.11 wireless networks, which is known as “EAP over LAN” or EAPOL.

The authentication process involves three parties: a supplicant (the client device), an authenticator (the network device such as an access point), and an authentication server (typically a RADIUS server). The supplicant must provide valid credentials to the authenticator before it can access the network resources.

The credentials are exchanged with a RADIUS server prior to the 4-way Handshake because the 4-way Handshake is used to establish encryption keys between the supplicant and authenticator after successful authentication2. The credentials are exchanged with a RADIUS server after the 802.11 Association because the 802.11 Association is used to establish a logical link between the supplicant and authenticator before authentication can take place3.

According to the Virtual Network Assistant | Juniper Networks US document3, two SLEs that measure the amount of time that it takes for a process to complete are:

Roaming, which measures how long it takes for a client to switch from one AP to another without losing connectivity.

Time to Connect, which measures how long it takes for a client to complete all steps of network access such as authentication, DHCP, and DNS.

Syslog is a protocol that can be used to forward event messages from Mist to an external log collector.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, syslog is a feature that enables forwarding event messages from Mist to an external log collector. Syslog messages can be sent over UDP or TCP protocols.

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

According to the Juniper Mist Wireless Deployment Service Datasheet1, a configuration template at the organization level can be applied to a site group, not to an individual site. Therefore, there is no option to mention the site in the config template at the organization level.
