Question 1 of 6

What role do 802.11 management frames play in a wireless network, and what security property did early implementations lack?

A. Management frames carry encrypted user data between client devices; early implementations lacked sufficient key length B. Management frames authenticate users by validating WPA2 passwords; early implementations did not support AES encryption C. Management frames coordinate network operations — including AP discovery, client association, quality of service, and disconnection — and were transmitted in plaintext without encryption or authentication in early 802.11, allowing any nearby device to forge them D. Management frames carry routing information between access points; early implementations lacked firewall integration

Question 2 of 6

To perform a wireless deauthentication attack, what does the attacker need? Select the MOST accurate answer.

A. The MAC address of the target device, the access point's BSSID, a wireless adapter in monitor mode, and physical proximity to the wireless network — the network password is NOT required B. The WPA2 or WPA3 passphrase of the target network C. Administrative credentials to the access point's management interface D. A valid IP address assignment on the target wireless network

Question 3 of 6

Which 802.11 management frames are protected by 802.11w, and which remain transmitted in plaintext by design?

A. 802.11w protects beacon and probe frames; deauthentication frames remain unprotected B. 802.11w protects deauthentication, disassociation, and channel switch announcements; beacon, probe, initial authentication, and association frames remain in plaintext because they must be exchanged before session keys are established C. 802.11w encrypts all management frames without exception D. 802.11w protects beacon and association frames; deauthentication frames are protected only on 802.11ax networks

Question 4 of 6

How does RF jamming disrupt wireless communication, and what property of the wireless medium does it attack?

A. RF jamming intercepts and modifies wireless frames in transit, targeting the data layer B. RF jamming exploits the same management frame vulnerability as deauthentication attacks but on the 5 GHz band C. RF jamming transmits interfering signals that reduce the signal-to-noise ratio on the target frequency — attacking the physical radio medium; devices cannot distinguish the AP's legitimate signal from noise, making communication impossible regardless of protocol security settings D. RF jamming floods the network with valid data frames, consuming bandwidth and preventing new connections

Question 5 of 6

What makes reactive jamming harder to detect than constant or random jamming?

A. Reactive jamming operates at a frequency too high for standard spectrum analyzers to detect B. Reactive jamming remains completely silent when the network is idle — transmitting interference only when legitimate wireless activity is detected; spectrum analysis shows nothing unusual in quiet periods, making it appear the network is functioning normally until someone tries to use it C. Reactive jamming uses frequency hopping that changes channels faster than spectrum analyzers can track D. Reactive jamming specifically targets only one device, making the attack pattern too small to appear on network-wide monitoring tools

Question 6 of 6

During a fox hunt to locate a jamming source, a network engineer uses a directional antenna and approaches the suspected area. As she gets close, the signal becomes so strong that her equipment shows maximum signal from all directions simultaneously, preventing her from determining the exact source location. What tool should she use, and why?

A. A wider-band omnidirectional antenna to pick up the signal from further away B. A GPS receiver to map the signal strength overlaid on building blueprints C. A signal attenuator — by reducing the effective signal strength, the attenuator brings the apparent signal level back within the range where the directional antenna can again discriminate between directions, allowing precise triangulation of the source D. A second directional antenna pointed in the opposite direction to cancel the interference

Matching — Wireless Attack Concepts

Match each term on the left to its correct description on the right.

1. Deauthentication Attack

2. Protected Management Frames (802.11w)

3. RF Jamming

4. 802.11 Management Frames

A. 802.11 control messages — including beacons, probes, association, and disconnection frames — that coordinate wireless network operations and were historically sent in plaintext

B. IEEE amendment that adds cryptographic authentication to deauthentication, disassociation, and channel switch announcement frames; mandatory in 802.11ac and newer

C. A DoS attack that forces wireless clients off a network by sending forged disconnection frames — no password required; requires proximity and target MAC addresses

D. A physical-layer attack that transmits interfering radio signals to raise the noise floor and prevent wireless communication; not mitigated by 802.11w
