Click the Exhibit button.
You notice a green LED emitted from your AP43.
Referring to the exhibit, what does this signal indicate?
- A. The AP is configured correctly with no users connected to it.
- B. The AP is not configured correctly but one user is connected to it.
- C. The AP is not configured correctly with no users connected to it.
- D. The AP is configured correctly and at least one user is connected to it.
正解：A
解説：
According to the exhibit, which shows the AP status table for Mist APs, a green LED emitted from an AP indicates that the AP is configured correctly with no users connected to it. This means that the AP has successfully connected to the Mist cloud and received its configuration, but there are no wireless clients associated with it. A green LED is different from a blue LED, which indicates that the AP is configured correctly and at least one user is connected to it. A red LED indicates that the AP is not configured correctly and has an error. A yellow LED indicates that the AP is in recovery mode and needs to be reset. Therefore, based on the exhibit, a green LED emitted from your AP43 means that the AP is configured correctly with no users connected to it.

According to the Administrator Roles page, there are five types of roles that can be assigned to users in a Mist organization: Super User, Network Admin, Helpdesk, Observer, and Installer2. Each type of role has different read and write capabilities for the organization and its sites2. Network Admin is one of the roles that can view audit logs, as it has limited read/write access to all sites under the organization and can access organization-level features such as Audit Logs and Inventory2. Network Admin can also open/update support tickets from the GUI2.
質問 # 22
You want to obtain detailed information on a wireless client.
In this scenario, which area would you use to accomplish this task?
- A. Insights
- B. Security
- C. Templates
- D. SLEs
正解：A
解説：
The area that you would use to obtain detailed information on a wireless client is the Insights area. The Insights area provides a comprehensive view of the wireless network performance and user experience, including the client dashboard, the live view, the service-level expectations (SLEs), and the Marvis virtual network assistant.
The client dashboard allows you to view and search for individual wireless clients and see their connection details, such as device type, MAC address, IP address, SSID, AP name, signal strength, throughput, data usage, location, and more. You can also perform actions on the clients, such as block, unblock, or capture packets.
The live view allows you to monitor the real-time status and activity of the wireless network and clients. You can see the number of connected clients, the traffic volume, the SLE scores, the top APs and SSIDs, and more. You can also filter and drill down into specific clients, APs, SSIDs, or sites.
The SLEs allow you to define and measure the quality of service and user experience for the wireless network. You can set thresholds and goals for key metrics, such as throughput, coverage, capacity, roaming, uptime, and WAN. You can also receive alerts and recommendations when the SLEs are violated.
The Marvis virtual network assistant allows you to interact with the wireless network using natural language commands. You can ask questions, troubleshoot issues, perform actions, and get insights from Marvis. For example, you can ask Marvis to show you the details of a wireless client or to explain why a client had a poor connection.
