A C
Explanation:
Real-time Assessment: Juniper Mist’s Radio Resource Management (RRM) builds the channel plan based on real-time network assessments. It dynamically adjusts to changing conditions in the RF environment, ensuring optimal performance by continuously monitoring factors such as interference, client distribution, and usage patterns.
Automatic Tuning: RRM tuning happens automatically. Mist AI leverages reinforcement learning to continually optimize RF settings without manual intervention, adjusting channels, power levels, and other parameters in real-time to maintain optimal network performance.

You are the network administrator for your company’s network. The network consists of two Active Directory domains: lmiweb.com and hr.lmiweb.com. The lmiweb.com domain supports most of the company’s user accounts and resources. The hr.lmiweb.com domain contains the user accounts and resources for the company’s human resources department.
The company has deployed an extensive 802.11b wireless network. Access points (APs) have been deployed throughout the company to provide users in all departments with wireless connectivity and serve as bridges to the wired LAN. A total of 325 users, including all members of hr.lmiweb.com, have been issued laptops with 802.11bcompliant network adapters. No other computers have wireless connectivity. All wireless LANs have Wired Equivalent Privacy (WEP) enabled to secure these communications.
Human resources users work throughout the company providing employee training and informational seminars. These users require access to the wireless LAN in all company locations. You must ensure that all human resources data is as secure as possible as it is transmitted across the wireless LAN. Only users with accounts in only specific users/computers groups should be able to access the human resources division’s wireless LAN.
In addition, users without accounts in this domain should not be able to view or select the LAN from their list of available networks.
