Question

The network administrator is investigating latency on a WiFi network. The administrator discovers a number of unidentified devices connected and wishes to limit access to only authorized users. Which of the following will BEST meet the requirement?

Options

AAssign static IP addresses

CDisable SSID broadcast
DLimit the DHCP scope

Explanation

MAC (Media Access Control) filtering creates an allowlist of specific hardware addresses, so only devices whose MAC addresses are pre-approved by the administrator can connect to the network. This directly addresses the goal of limiting access to authorized devices. Assigning static IPs does not prevent unknown devices from joining. Disabling SSID broadcast hides the network name but does not block connections-anyone who knows the SSID can still connect. Limiting the DHCP scope only reduces the number of IP addresses available but does not authenticate or restrict which devices receive them.
