Enable WPA3 encryption O B. Remove unauthorized MAC addresses from the filter O C. Modify the SSID name O D. Modify the channel

The Answer: A. Enable WPA3 encryption A MAC (Media Access Control) address can be spoofed on a remote device, which means anyone within the vicinity of the access point can view legitimate MAC addresses and spoof them to avoid the MAC filter. To ensure proper authentication, the system administrator can enable WPA3 (Wi-Fi Protected Access version 3) with a shared key, or configure 802.1X to integrate with an existing authentication database.

The Answer: C. 802. IX IEEE 802. IX is a standard for port-based network access control (NAC). When 802.1X is enabled, devices connecting to the network do not gain access until they provide the correct authentication credentials. "this 802. IX standard refers to the client as the supplicant, the switch is commonly configured as the authenticator, and the back- end authentication server is a centralized user database such as Active Directory.
