300-430 · Question #3

Which two events are outcomes of a successful RF jamming attack? (Choose two.)

The correct answer is A. disruption of WLAN services E. physical damage to AP hardware. RF jamming attacks operate at the physical layer by flooding the spectrum with interference, causing service disruption and potentially physical hardware damage from high-power signals.

Why each option

RF jamming attacks operate at the physical layer by flooding the spectrum with interference, causing service disruption and potentially physical hardware damage from high-power signals.

Adisruption of WLAN servicesCorrect

RF jamming transmits sustained radio frequency interference across the 2.4 GHz or 5 GHz spectrum, overwhelming legitimate 802.11 signals and causing a denial-of-service condition that prevents all WLAN communication in the affected area.

Bunauthentication association

Unauthentication association is not a recognized IEEE 802.11 event or outcome of RF jamming - jamming acts at the physical layer and does not interact with 802.11 association state machines.

Cdeauthentication broadcast

Deauthentication broadcasts result from management frame spoofing attacks where an adversary sends forged 802.11 deauth frames, not from RF jamming which has no awareness of upper-layer 802.11 management frames.

Ddeauthentication multicast

Deauthentication multicasts are a characteristic of management frame injection attacks, not of RF jamming which disrupts physical-layer signal propagation rather than crafting 802.11 frames.

Ephysical damage to AP hardwareCorrect

Sufficiently high-powered RF jamming can induce damaging voltages in the antenna and RF front-end circuitry of access points, causing physical degradation or failure of the radio hardware components.
