According to Wikipedia 1 , 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 authentication 2 . 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 place 3 .

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.

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

Two correct statements about Juniper Mist Dynamic Packet Capture are that no configuration is necessary for Mist’s Dynamic Packet Capture and it is automatically attached to a client event displayed on the Insights page. So the correct answers are  A. No configuration is necessary for Mist’s Dynamic Packet Capture  and  B. It is automatically attached to a client event displayed on the Insights page .

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 Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide 1 , 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 AP Offline Marvis Action will consider all APs assigned to sites that have connected to the cloud previously for inclusion. So the correct answer is  A. all APs assigned to sites that have connected to the cloud previously .

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

According to the Initial AP Connection and VLANs & Static IP addresses - Mist document 1 , 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.
