The answer is a de-authentication attack followed by an evil twin. This is correct because the attacker first sends de-authentication packets to disconnect the client from the legitimate access point, then uses an evil twin—a rogue AP broadcasting the same SSID—to lure the client into automatically reconnecting. On the Certified Ethical Hacker CEH exam, this scenario tests your understanding of wireless attack chains, where the deauthentication attack is the trigger that forces client connection to the rogue AP, not the evil twin itself. A common trap is assuming the evil twin alone causes the disconnection; remember, the evil twin only impersonates the network, while de-authentication packets do the forceful kicking. A useful memory tip: think of it as “de-auth to disconnect, evil twin to collect”—the attacker needs both steps to redirect traffic to a fake login page.
CEH Practice Question: Advanced Topics: Wireless, Cloud, IoT, Cryptography
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.
A security analyst notices that after a user connects to a corporate Wi-Fi network, all HTTP traffic is redirected to a fake login page that captures credentials. The analyst suspects a rogue access point. Which attack is most likely being used to force client connections to the rogue AP?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: An evil twin is a rogue AP that mimics a legitimate one, but the method to force clients to connect is often de-authentication, not just signal strength.
B
WPA2 dictionary attack on the handshake
Why wrong: Dictionary attack cracks the PSK after capturing the handshake, not redirects traffic.
C
WPS PIN brute-force attack
Why wrong: WPS attacks target the PIN to gain PSK; they don't redirect traffic to a fake login page.
D
De-authentication attack followed by evil twin
De-auth packets disconnect clients; they then connect to the rogue AP (evil twin) which serves a fake login page.
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 followed by evil twin
De-authentication packets force clients to disconnect from the legitimate AP, after which they may automatically reconnect to a rogue AP with the same SSID. Evil twin is the fake AP, but the mechanism to disconnect clients is de-authentication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CEH exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
