Juniper Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) Sample Questions (Q127-Q132):

NEW QUESTION # 127
You are asked to harden the security of your wireless infrastructure. Upon inspecting the different available options, you see a check box for detecting rogue and neighbor access points.
In this scenario, what is a rogue access point?

A. Rogue access points share the same local area network but are unknown to your organization.
B. Rogue access points share the same wide area network and are known to your organization.
C. Rogue access points share the same local area network and are known to your organization.
D. Rogue access points share the same wide area network but are unknown to your organization.

Answer: A

Explanation:
A rogue access point is an unauthorized AP that is connected to the same local network as the organization's infrastructure. Because it is unknown and unmanaged, it can create a security risk by allowing unintended access to the internal network.

NEW QUESTION # 128
Which two statements are true about 802.1X/EAP? (Choose two.)

A. Credentials are exchanged with a RADIUS server after the 4-way Handshake.
B. Credentials are exchanged with a RADIUS server prior to the 4-way Handshake.
C. Credentials are exchanged with a RADIUS server prior to the 802.11 Association.
D. Credentials are exchanged with a RADIUS server after the 802.11 Association.

Answer: B,D

Explanation:
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.

NEW QUESTION # 129
You are building your floor plan for a recent Juniper Mist deployment and you must ensure that when you are finished, you can track user movements and locations throughout the floor plan. In this scenario, which statement is correct regarding AP orientation in the Mist UI?

A. In the UI, the APs must all be oriented on the floor plan to face geographical north.
B. In the UI, the orientation of the APs will not affect Mist's location services.
C. In the UI, the APs must be oriented on the floor plan in the same direction as the physical APs.
D. In the UI, the APs must all be oriented on the floor plan to face true north.

Answer: C

Explanation:
In a Juniper Mist AI deployment, achieving high-fidelity location accuracy is entirely dependent on the digital twin (the floor plan in the Mist UI) accurately reflecting the physical environment. While scaling the map is the foundation, AP orientation is the most critical variable for the vBLE (virtual Bluetooth Low Energy) engine to correctly calculate a client's position.
Mist Access Points, such as the AP43 or AP45, feature a patented 16-element directional vBLE antenna array. This array does not broadcast in a simple omnidirectional circle; instead, it uses eight distinct directional beams to blanket an area. The Mist Cloud uses "probability surfaces" to determine a user's location by examining the RF fingerprints from these specific beams. If an AP is physically mounted with its LED pointing toward a specific hallway, but is oriented in the Mist UI facing a different direction, the location engine will receive signal data that does not match its internal map of the beams. This results in "flipped" locations or "teleporting," where a user appears on the opposite side of the AP from where they actually are.
To ensure accuracy, administrators must use the small green dot on the outer ring of the AP icon in the Mist Live View. This green dot represents the physical LED on the AP hardware. The orientation in the UI must be rotated so that the green dot points in the exact same direction as the physical LED relative to the floor plan's perspective. It is a common misconception that APs must face true north (A) or geographical north (D); the map and APs can be oriented in any way that is convenient for the facility layout, provided the relative alignment between the virtual icon and the physical device is identical.

NEW QUESTION # 130
Using the Marvis Query Language, which three query types would you use for chat? (Choose three.)

A. troubleshoot
B. locate
C. limit
D. select
E. list

Answer: A,B,E

Explanation:
Marvis Query Language chat supports query types such as troubleshooting a problem, locating a client or device, and listing relevant information. These query types allow Marvis to interpret natural-language operational requests and return actionable wireless insights.

NEW QUESTION # 131
What is the primary purpose of channel bonding in 802.11n/ac/ax networks?

A. To allow an access point to simultaneously operate on two different channels to serve more clients.
B. To encrypt the management frames sent on a channel.
C. To reduce the RF interference from neighboring access points.
D. To combine two or more adjacent channels into a single, wider channel to increase the potential data throughput.

Answer: D
