A university campus deploys a new Wi-Fi 6 network. During testing, the network team finds that clients in a courtyard with many large trees experience lower data rates than expected, even at close range to the AP. The trees are dense with leaves and branches. Which RF propagation phenomenon is most likely responsible?

Diffraction around the tree branches

Scattering by the leaves causing signal dispersion

Signal absorption by the water content in the leaves

Multipath reflection off the tree trunks

A network administrator is designing a wireless network for a large convention center. The center hosts events with hundreds of attendees, each with multiple wireless devices. The administrator needs to ensure that the network can handle the high client density without excessive interference. Which approach is most effective?

Use a single access point with a high-gain antenna to cover the entire convention floor.

Use only 2.4 GHz to maximize range and reduce the number of access points needed.

Deploy multiple access points on non-overlapping channels and reduce transmit power to create smaller cells.

Use a mesh network with access points that relay traffic to a central AP.

A company's wireless network uses WPA2-Enterprise with PEAP. The security team discovers that an attacker has set up a rogue access point with the same SSID and is using a fake RADIUS server to capture credentials. Which wireless threat is being exploited?

Eavesdropping on wireless traffic

Denial of service via deauthentication

Rogue access point and credential theft

Part of the Wireless Fundamentals and Threats domain, which makes up ~22% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~11–18 in this domain), expect 3–5 from this objective — we provide 33 practice questions to prepare you well beyond it.
