You are installing and booting up your first Juniper Mist AP at your site.By default, which two statements are correct in this scenario? (Choose two.)
Answer(s): A,B
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.

Which two statements are true about 802.1X/EAP? (Choose two.)
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.
Click the Exhibit button.Referring to the exhibit, what is the meaning of the AI VALIDATED status update?
Answer(s): B
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.

Which access points (APs) will be considered for inclusion in the AP Offline Marvis Action?
Answer(s): A
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.
Which Wireless Assurance SLE has classifiers of Association, Authorization, DHCP, and Internet Services?
Answer(s): C
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.

Regarding the seven layer OSI networking model, which two layers are different between Ethernet and Wi-Fi? (Choose two.)
Answer(s): A,D
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.

A customer is replacing their previous WLAN controller with a Mist Edge to maintain centralization of user traffic.How does Mist Edge affect control plane forwarding and data plane forwarding in this scenario?
When a customer replaces their previous WLAN controller with a Mist Edge in order to maintain centralization of user traffic, control plane forwarding applies to the Mist Cloud while data plane forwarding applies to the Mist Edge. So the correct answer is A. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.
Click the Exhibit button.Users are occasionally having problems connecting to the Internet using Wi-Fi. You suspect possible interference from a neighboring Wi-Fi network.Referring to the exhibit, which Wi-Fi Assurance SLE and classifier would provide information about this issue?
Answer(s): D
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.
