NEW QUESTION # 16
You are asked to create a label that will be applied to a WLAN template.
In this scenario, under which level should you create the label?
- A. clients
- B. organization
- C. WLAN
- D. site
Answer: D
Explanation:
When creating a label to be applied to a WLAN template in Mist AI, you should create the label at the site level. This is because WLAN templates are designed to be associated with specific sites or site groups, allowing you to customize WLAN configurations per site. Creating labels at the site level ensures that these configurations are applied appropriately within the desired site context.
NEW QUESTION # 17
As an organization administrator, what are two ways to configure additional layers of security for administrator logins? (Choose two.)
- A. Increase session timeouts.
- B. Disable a password policy.
- C. Enable a password policy.
- D. Enable two-factor authentication.
Answer: C,D
Explanation:
Enable Two-Factor Authentication (2FA): Adding 2FA to administrator logins significantly enhances security by requiring a second form of verification in addition to the password, making unauthorized access more difficult.
Enable a Password Policy: Implementing a strong password policy ensures that passwords meet certain complexity and length requirements, reducing the risk of brute force attacks.
NEW QUESTION # 18
Which two use cases are popular in location-based services (LBS) deployments? (Choose two.)
- A. micro segmentation
- B. way finding
- C. asset tracking
- D. SSID scheduling
Answer: B,C
Explanation:
Asset Tracking: Asset tracking is a common use case in LBS deployments, enabling organizations to locate and manage assets in real-time. This is particularly useful in environments like hospitals, warehouses, and large corporate campuses where knowing the precise location of equipment can save time and improve efficiency.
Wayfinding: Wayfinding helps users navigate through complex environments, such as large buildings, airports, and shopping malls. By providing real-time navigation assistance, LBS enhances the user experience and improves accessibility within these spaces.
NEW QUESTION # 19
How does Mist determine the location of clients in an indoor setting?
- A. triangulation
- B. GPS
- C. probability surface
- D. trilateration
Answer: C
Explanation:
Mist builds location from "Probability Surfaces" not triangulation. The more directional RSSI beam information your client hears, the more data for the location engine to work with creating the probability surfaces, which provides the best possible location accuracy with sub second latency.
NEW QUESTION # 20
In the Mist UI, what are two Marvis Actions for the AP category? (Choose two.)
- A. Health Check Failed
- B. MTU Mismatch
- C. Coverage Hole
- D. High CPU
Answer: A,C
Explanation:
Coverage Hole: Marvis Actions can identify coverage holes where the wireless signal is weak or absent, indicating potential areas that need additional access points or adjustments.
Health Check Failed: This action indicates that the health check, which monitors the performance and connectivity of an access point, has failed, suggesting issues that need to be addressed.
NEW QUESTION # 21
Which two statements correctly describe Mist claim codes and activation codes? (Choose two.)
- A. An activation code is printed on a sticker on the AP.

NEW QUESTION # 26
You scheduled downtime to push the latest firmware to all the APs you deployed at the site. You verified that all of the APs are working fine. When you go back to work, you notice no complaints from the users. When you check the AP page, you notice that several APs have not rolled out with the latest firmware.
In this scenario, how does Marvis categorize this issue in the Marvis Action dashboard?
- A. The port flap Marvis Action is displayed.
- B. The missing VLAN Marvis Action is displayed.
- C. The non-compliant Marvis Action is displayed.
- D. The high CPU Marvis Action is displayed.
Answer: C
Explanation:
When several APs fail to update to the latest firmware during a scheduled downtime, Marvis categorizes this issue as a "non-compliant" action.
This categorization indicates that some APs are not adhering to the intended firmware version policy, which could potentially affect network performance or security. The non-compliant Marvis Action provides administrators with the necessary information to identify and rectify the issue, ensuring all APs are updated as required.
