Question 1

What is the impact of adding more SSIDs to a radio?



Answer : A

The impact of adding more SSIDs to a radio is beacon overhead.So,the correct answer is A.beacon overhead


Question 2

All the access points (APs) on the site will obtain an IP address for the Management VLAN. You notice an additional IP address for each configured VLAN on the AP.

Which statement is correct in this scenario?



Answer : C

According to the Mist documentation1, a Mist AP will pull a management IP address from the Native VLAN by default. However, if the Local Status Page is configured for the Site, all the site APs will pull their own IP address from the Management VLAN, but also addresses for each of the VLANs configured on the AP. This is because each AP creates a Switch Virtual Interface (SVI) for each VLAN on its eth0 interface.

The Local Status Page is a feature that allows you to access information about an AP's status and configuration through a web browser by connecting to its IP address2. This feature can be enabled or disabled at the site level under Site Settings > Access Points > Advanced Settings.


Question 3

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 : 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.


Question 4

Which Wireless Assurance SLE has classifiers of Association, Authorization, DHCP, and Internet Services?



Answer : 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.


Question 5

What are two functions of Mist Radio Resource Management (RRM)? (Choose two.)



Answer : A, C

Mist Radio Resource Management (RRM) performs several functions including transmit power control and channel assignment which help optimize wireless network performance by dynamically adjusting radio settings based on changing environmental conditions.So,the correct answers are A.transmit power control and C.channel assignment

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, two functions of Mist Radio Resource Management (RRM) are:

Transmit power control, which adjusts the transmit power of APs based on their coverage area and interference level.

Channel assignment, which assigns channels to APs based on their location and interference level.


Question 6

Click the Exhibit button.

Referring to the exhibit, what would a guest user be able to do?



Answer : B

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It typically establishes a barrier between a trusted internal network and an untrusted external network, such as the Internet .


Question 7

Which two Mist Aps would be used for BLE location? (Choose two.)



Answer : B, D

According to the JNCIS-MistAI Certification page2, 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.
