JN0-451 Mist AI - Specialist (JNCIS-MistAI) Questions and Answers

Two authentication methods that would be used with a guest portal are social login and external portal. So the correct answers are  A. social login  and  B. external portal .

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide 2 , two authentication methods that can be used with a guest portal are:

Social login, which allows guests to log in using their social media accounts such as Facebook, Twitter, or Google.

External portal, which allows guests to log in using an external web server that hosts a custom portal page.

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 .

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 .

Basic data rates are the required data rates that all devices on a wireless network must support in order to connect to the network. These rates are used for management and control frames and can affect the performance of the network.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document 2 , basic data rates are required data rates that all devices must support to communicate on a WLAN.

According to the Location - how it works - Mist document 1 , 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.

According to the JNCIS-MistAI Certification page 2 , 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.

When using location-based services (LBS) at a new warehouse and placing APs on the floor plan with correct scale while ensuring correct location accuracy in this scenario where APs are mounted on trusses 14 feet (4.3 meters) from floor, two actions that should be taken are installing Virtual Beacons in each aisle and configuring height of each AP. So the correct answers are  A. Install Virtual Beacons in each aisle  and  B. Configure height of 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.

The Wi-Fi Assurance SLE and classifier that would provide information about possible interference from a neighboring Wi-Fi network are Capacity and Wi-Fi Interference.

If a customer added an Apple TV in their conference room so that employees can easily share their screen but the Apple TV cannot be discovered by the employees’ devices, two settings that could be causing this problem are MDNS and Broadcast/Multicast. So the correct answers are  A. MDNS  and  B. Broadcast/Multicast .

The exhibit shows a graph of the client’s roaming history over time. The x-axis represents the time and the y-axis represents the access point ID. Each dot on the graph indicates a roam event where the client switched from one access point to another.

The graph shows that the client roamed between different access points multiple times within a short period of time. This indicates that the client was experiencing frequent roams between different access points, which could affect its network performance and user experience.

Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document 2 , channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput. This doubles the available bandwidth but also doubles the required device resources such as power and processing.

According to the Webhooks - Mist document, two types of information that would be streamed through webhooks are:

Alerts, which are notifications that are triggered by certain events or conditions on the network.

SLE metrics of clients, which are service level expectations that measure the quality of experience for clients on various aspects such as connection, coverage, capacity, throughput, and roaming.

If a customer wants to broadcast a WLAN at a certain time and day of the week, SSID scheduling should be configured

According to the SSID Scheduling - Mist document 1 , SSID scheduling is a feature that allows you to customize your WLAN by choosing the exact days and times to broadcast the SSID. This feature can be useful for scenarios where you want to limit the availability of a WLAN to a certain time and day of the week.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide 1 , 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.

According to the Marvis - Mist document, Correlation is a category in Marvis’ troubleshooting response that shows when the AP went offline. Correlation shows the correlation between events and SLEs for a given client or AP.
