Juniper JN0-451 Mist AI - Specialist (JNCIS-MistAI) Exam Practice Test

Two events that are displayed under Client Events area found on Insights page are Reassociation and DHCP Denied. So the correct answers are A. Reassociation and D. DHCP Denied.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document3, two layers that are different between Ethernet and Wi-Fi in the OSI networking model are:

• Media access control (MAC) sub-layer, which is part of the data link layer and defines how devices access and share the wireless medium.
• Physical layer, which defines how data is encoded and transmitted over the wireless medium.

According to the exhibit, the WLAN has a minimum basic rate of 24 Mbps for both 2.4 GHz and 5 GHz bands. This corresponds to the high-density data rate setting in Mist, which disables all data rates below 24 Mbps. This setting is recommended for high density designs, where clients have enough signal strength and quality to operate at higher rates.

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.

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.

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 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 Virtual Network Assistant | Juniper Networks US document2, Time to Connect is a Wireless Assurance SLE that has classifiers of Association, Authorization, DHCP, and Internet Services. This SLE measures how long it takes for a client device to connect to the network and access internet services.

 According to the Data Rates - Mist document1, a honeypot AP is an AP that is not associated with your network, but broadcasts your corporate login page and WLAN name. This is a type of rogue AP that tries to trick users into connecting to it and revealing their credentials or other sensitive information.

According to the Initial AP Connection and VLANs & Static IP addresses - Mist document1, when a Juniper Mist AP boots up for the first time, it will expect to see a trunked port or the native VLAN=1 and will send a DHCP request on that VLAN. The AP will attempt to connect to the Mist cloud using port 443, which is the default HTTPS port.
