What the exam tests

What to know about Wireless Networking Technologies

Wireless security questions usually test authentication protocols (WPA2/WPA3), encryption modes, 802.11 standards and troubleshooting clients that cannot connect or associate.

WPA2 vs WPA3 authentication and encryption standards.

802.11 wireless standards, frequency bands and channel behaviour.

WLAN client troubleshooting — association, authentication and DHCP.

How SSID, authentication method and pre-shared key affect wireless access.

Watch out for

Common Wireless Networking Technologies exam traps

  • WPA2-Enterprise uses 802.1X and a RADIUS server, not a pre-shared key.
  • WPA3 provides stronger encryption but backwards compatibility is not guaranteed.
  • A client can associate to an AP and still fail to reach the network.
  • 5 GHz gives higher throughput but shorter range than 2.4 GHz.
