Question 1

A user with a PSK calls you and says, ''The Wi-Fi worked for a week and now it does not work.'' There have not been any recent configuration changes to the network. You suspect that a time-based setting has reset the key.

In this scenario, where would you begin troubleshooting?



Answer : C

In this scenario, you would begin troubleshooting by checking the WLAN-level Pre-Shared Keys.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, you can configure a time-based setting for WLAN-level Pre-Shared Keys (PSKs) that will reset the key after a specified interval. This feature is useful for enhancing security and preventing unauthorized access. If a user reports that the Wi-Fi worked for a week and now it does not work, you should check the WLAN-level PSK settings and see if the key has been changed.


Question 2

Which Wireless Assurance SLE provides information on Opportunistic Key Caching (OKC)?



Answer : B


According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, the Wireless Assurance SLE that provides information on Opportunistic Key Caching (OKC) is Roaming. OKC is a fast roaming technique that allows wireless clients and the WLAN infrastructure to cache only one PMK for client association with a WLAN, even when roaming between multiple APs.

Question 3

You are deploying multiple Mist APs across many sites in your network. You must ensure that you can group similar devices together to easily apply consistent WxLAN policies across multiple sites.

Which configuration object should be used to accomplish this behavior?



Answer : B

When deploying multiple Mist APs across many sites in your network and grouping similar devices together to easily apply consistent WxLAN policies across multiple sites, you should use device profiles.


Question 4

You must define VLANs as untagged, tagged, or using VLAN pooling.

In this scenario, where would you accomplish this task in the Juniper Mist UI?



Answer : B

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.


Question 5

What are two ways to access Marvis? (Choose two.)



Answer : A, B

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, 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.


Question 6

Click the Exhibit button.

Referring to the exhibit, as part of the Throughput SLE in the Mist UI, the Coverage classifier indicates the signal strength of which device?



Answer : C

As part of the Throughput SLE in the Mist UI, the Coverage classifier indicates the signal strength of the client.


Question 7

Which two statements are correct about channel bonding? (Choose two.)



Answer : A, B

Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput. This doubles the available bandwidth but also doubles the required device resources such as power and processing.
