Quick Answer
The answer is evil twin and de-authentication attacks. These are specifically associated with wireless networks because they exploit the unencrypted management frames in the IEEE 802.11 protocol, a vulnerability unique to Wi-Fi environments. A de-authentication attack forges frames to forcibly disconnect a client from an access point, often to capture the WPA handshake or set up an evil twin—a rogue access point that mimics a legitimate one to intercept credentials. On the Certified Ethical Hacker CEH exam, this topic tests your understanding of wireless attack vectors and frame types; a common trap is confusing de-authentication with denial-of-service, but the key is that it targets management frames, not data frames. To remember, think of the “twin” trick: the evil twin lures you in, while de-auth kicks you out to make you connect to it.
This CEH practice question tests your understanding of advanced topics: wireless, cloud, iot, cryptography. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following attacks are specifically associated with wireless networks?
Man-in-the-middle attack
Why wrong: MITM is generic; can be performed on wired or wireless.
De-authentication attack
De-auth attacks disconnect clients from a WLAN.
Evil twin attack
An evil twin is a rogue access point that mimics a legitimate one.
Replay attack
Why wrong: Replay attacks can occur in many contexts, not just wireless.
Birthday attack
Why wrong: Birthday attack is a cryptanalytic attack on hash functions.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
De-authentication attack
A de-authentication attack targets the management frames in IEEE 802.11 wireless networks. An attacker sends forged de-authentication frames to disconnect a client from an access point, often as a precursor to capturing the WPA handshake or launching an evil twin attack. This is a wireless-specific attack because it exploits the unencrypted nature of 802.11 management frames.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
EC-Council often tests the distinction between attacks that are 'specific to wireless' versus those that are 'general network attacks' — the trap is that candidates confuse a common attack vector (like man-in-the-middle) with a protocol-specific vulnerability unique to 802.11.
Detailed technical explanation
De-authentication attacks exploit the fact that 802.11 management frames are not encrypted or authenticated by default (prior to 802.11w-2009). Tools like aircrack-ng's aireplay-ng send de-auth packets using the station's MAC address as the source, forcing the client to re-authenticate and allowing the attacker to capture the 4-way handshake. The evil twin attack involves setting up a rogue access point with the same SSID as a legitimate network, often combined with a de-auth attack to force clients onto the rogue AP, where credentials can be harvested via a captive portal.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
