Cyber Fundamentals Block 1 Practice Exam

Wireless networks are a broadcast medium, with signals traveling through the air. Because of that, a device within range can discover the network and attempt to connect without needing a physical cable. If the network has weak security or a simple password, an unsanctioned device can join more easily than on a wired network, which requires physical access to a port and usually stricter controls. Strong security like WPA3 or 802.1X can restrict access, but the basic trait of air-based access makes it easier for unauthorized devices to connect. The other statements aren’t generally true: wireless networks use Ethernet for backhaul to the broader network, so they are not isolated from wired infrastructure, and with current standards, wireless speeds can be very high and sometimes rival or surpass older wired connections, so it isn’t accurate to say wireless is always slower.
