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.
An attacker sets up a rogue access point with the same SSID as a legitimate corporate network and broadcasts a stronger signal. Clients connect to the rogue AP. What type of attack is this?
WPS PIN attack
Why wrong: WPS PIN attack targets the WPS feature, not SSID spoofing.
De-authentication attack
Why wrong: De-auth attacks disconnect clients, but the rogue AP is set up to attract connections.
Evil twin attack
This describes an evil twin attack exactly.
MAC spoofing attack
Why wrong: MAC spoofing is changing a device's MAC address, not setting up a rogue AP.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Evil twin attack
An evil twin attack involves a rogue AP mimicking a legitimate SSID to intercept traffic.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
WPS PIN attack
Why it's wrong here
WPS PIN attack targets the WPS feature, not SSID spoofing.
De-authentication attack
Why it's wrong here
De-auth attacks disconnect clients, but the rogue AP is set up to attract connections.
Evil twin attack
Why this is correct
This describes an evil twin attack exactly.
Related concept
CIDR notation defines the prefix length.
MAC spoofing attack
Why it's wrong here
MAC spoofing is changing a device's MAC address, not setting up a rogue AP.
Common exam traps
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related CEH subnetting questions on CIDR, address ranges, and subnet selection.
