1. In a vBLE deployment, what is the recommended minimum number of APs that a client device should be able to "hear" for accurate location?

2. An administrator has configured a Mist Tunnel at the organization level, defining a primary and a secondary Mist Edge cluster for redundancy. They now need to apply this tunneled configuration to a specific corporate WLAN.

Where in the Mist UI is the Mist Tunnel object associated with the WLAN? (Choose 2.)

3. An organization has standardized its wireless network configuration using a WLAN template and an RF template, which are applied to all sites.

6. An administrator needs to create a WxLAN policy that allows all authenticated employees to access the internet but prevents them from accessing a specific internal server with the IP address 10.100.1.50, which hosts sensitive financial data.

Which two WxLAN policy rules, in the correct order, would accomplish this? (Choose 2.)

7. A hospital is using the Asset Visibility feature to track wheelchairs. They notice that the location of a specific wheelchair is not updating.

What kind of information would you expect to see?

10. Which statement is true about how RF Templates, Device Profiles, and individual AP settings are applied?

11. Which security standard is mandatory for WPA3, providing stronger protection against offline dictionary attacks compared to WPA2-PSK?

12. Which 802.11 standard introduced multi-user MIMO (MU-MIMO) for the downlink, allowing an AP to transmit to multiple clients simultaneously?

13. An administrator is troubleshooting a newly installed AP43 that is showing as "Disconnected" in the Mist UI. The AP's status LED is blinking yellow seven times repeatedly.

AP LED Status:

- Blink Pattern: Yellow, Yellow, Yellow, Yellow, Yellow, Yellow, Yellow (Pause) ... Repeat

What is the most likely cause of the AP disconnection?

14. An administrator is deploying a new wireless network and wants to use the autoplacement feature to position the APs on the floorplan.

Which two conditions must be met before running the autoplacement process for a new site? (Select all that apply.)

15. Which type of 802.11 management frame is responsible for carrying information such as the SSID, supported data rates, and security capabilities, and is periodically broadcast by an access point so that clients can passively discover the network?

16. Marvis Minis is a feature that helps administrators understand the scope of a network issue.

What does it do?

17. A client device is associated with a Mist AP. The administrator wants to see a detailed chronological log of all major connection events for this specific client, including every time it associated, roamed, or failed an authentication.

Which tool in the Mist dashboard provides this specific view?

18. When configuring a WLAN to use an external captive portal, what information must Mist provide to the external portal server to identify the client session?

19. A college is experiencing poor Wi-Fi performance in a lecture hall. An administrator reviews the SLE dashboards and finds that while Coverage and Successful Connects are good, the Capacity and Throughput SLEs are very low during class times. The primary classifier for the Capacity failure is "High Bandwidth Utilization," and the primary classifier for the Throughput failure is "Capacity."

What is the most logical conclusion and the best course of action?

20. Which two are valid query types in the Marvis conversational interface? (Choose two.)

21. A university is preparing for final exams week and expects a very high density of users in the library. The IT team wants to proactively optimize the wireless network to handle the increased load. The APs are all dual-band capable.

Which two RRM configurations would be most effective in this scenario? (Select all that apply.)

22. When designing a wireless network for a high-density environment like a lecture hall, which Mist AP feature is specifically designed to optimize performance by dynamically adjusting channel and power settings based on real-time RF conditions?

23. In the context of 802.1X, what is the role of the supplicant?

24. What is the main advantage of using Wi-Fi 6 (802.11ax) in an IoT deployment with many low-power, low-bandwidth devices?

25. A user at a campus location reports that their VoIP calls frequently drop when they walk between buildings. The administrator checks the Roaming SLE and sees failures attributed to the "Slow Standard Roams" classifier for this user.

What is the time threshold that defines a "Slow Standard Roam" in the Mist platform?

26. Which Marvis query would an administrator use to identify the wireless clients that have experienced the most connection problems within the last 24 hours?

27. A Mist AP is placed on the floorplan in the UI, but its orientation is incorrect, causing location accuracy issues.

What AP setting needs to be adjusted?

28. An administrator is deploying a floorplan for accurate vBLE location services. They have already uploaded the floorplan image and correctly placed and oriented all the APs.

What is the critical next step they must perform to ensure the location engine can make accurate calculations?

29. A network administrator is troubleshooting a connectivity issue for a single user.

Which tool in the Mist dashboard provides a detailed, chronological log of events for that specific client, including associations, roams, and failures?

30. When configuring an RF Template, you set the 5 GHz band to use 80 MHz channels.

What is a potential negative consequence of this configuration?

31. An administrator is setting up location services for a new site. They have uploaded a high-quality floorplan image. To ensure accurate wayfinding and asset tracking, the APs must be positioned correctly on the map.

Which tool in the Mist "Location > Live View" UI is used to define the relationship between pixels on the image and real-world distance?

32. A network operator receives a "Negotiation Mismatch" SLE from the Mist dashboard.

What is the most likely cause of this issue?

33. A museum wants to create an interactive experience for visitors. When a visitor with the museum's mobile app approaches a specific exhibit, the app should display additional information about that exhibit.

Tunnel Interface Configuration

[ ] Separate Upstream and Downstream Traffic

...

Interface Upstream/Downstream

xe0 [x]

xe1 [x]

...

If the administrator selects "Single Arm" and checks multiple interfaces (e.g., xe0 and xe1), what protocol is automatically enabled on the corresponding switch ports to bundle these physical links into a single logical link?

37. A WxLAN policy has the following rules in order:
