Question 145 of 520
N10-009 Network Security Practice Question
This N10-009 practice question tests your understanding of network security. 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 is investigating a user's complaint that their wireless connection keeps disconnecting. The analyst uses a wireless scanning tool and discovers two access points broadcasting the same SSID 'CorpNet' with different BSSIDs. One is the legitimate company AP on channel 1, and the other is on channel 11 with a strong signal and security set to 'Open'. Which of the following attacks is most likely occurring?

Correct answer & explanation
✓
Evil twin
The presence of two access points broadcasting the same SSID 'CorpNet' with different BSSIDs, where the second AP is on channel 11 with a strong signal and security set to 'Open', is characteristic of an evil twin attack. The attacker sets up a fraudulent AP with the same SSID as the legitimate network but without encryption, tricking users into connecting to it and exposing their credentials or traffic. This differs from a rogue AP, which typically mimics the corporate network but may not necessarily use an open security setting or a different channel to lure victims.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
War driving
Why it's wrong here
War driving is the act of mapping wireless access points, not actively attacking users by impersonating an AP.
When this WOULD be correct
War driving would be correct if the question described an attacker driving around a city to map wireless networks and identify vulnerable ones, without any mention of a fake AP or disconnection complaints.
- ✗
Rogue access point
Why it's wrong here
While a rogue AP is an unauthorized AP, the scenario specifically describes an AP that is spoofing the legitimate SSID with open security, which is an evil twin attack. 'Evil twin' is more precise.
When this WOULD be correct
A rogue access point would be correct if the question stated that an unauthorized AP was discovered connected to the company's wired network, potentially allowing bypass of security controls, without mention of spoofing the SSID or open security.
- ✓
Evil twin
Why this is correct
The presence of two APs with the same SSID, one with strong signal and open security, strongly indicates an evil twin attack designed to capture credentials and traffic.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Bluesnarfing
Why it's wrong here
Bluesnarfing is an attack on Bluetooth devices, not on Wi-Fi networks.
When this WOULD be correct
A user reports that their Bluetooth headset has been paired with an unknown device and they are experiencing audio dropouts. A security analyst discovers that an attacker is using a Bluetooth vulnerability to access the headset's contact list and call history. Bluesnarfing would be the correct answer.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.

Why this is correct
The presence of two APs with the same SSID, one with strong signal and open security, strongly indicates an evil twin attack designed to capture credentials and traffic.
✗War drivingWrong answer — click to see why▾
Why this is wrong here
War driving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle, using a portable device. It does not involve setting up a fake access point to intercept connections, which is what the scenario describes.
★ When this WOULD be the correct answer
War driving would be correct if the question described an attacker driving around a city to map wireless networks and identify vulnerable ones, without any mention of a fake AP or disconnection complaints.
Why candidates choose this
Candidates may confuse war driving with any wireless attack involving scanning, because the scenario mentions using a wireless scanning tool, which is also used in war driving.
✗Rogue access pointWrong answer — click to see why▾
Why this is wrong here
A rogue access point is an unauthorized AP connected to the network, but the question describes an AP broadcasting the same SSID with an open security setting, which is characteristic of an evil twin attack, not a rogue AP.
★ When this WOULD be the correct answer
A rogue access point would be correct if the question stated that an unauthorized AP was discovered connected to the company's wired network, potentially allowing bypass of security controls, without mention of spoofing the SSID or open security.
Why candidates choose this
Candidates may confuse 'rogue access point' with any unauthorized wireless device, but the key distinction is that a rogue AP is physically connected to the network, whereas an evil twin merely mimics the SSID without network access.
✗BluesnarfingWrong answer — click to see why▾
Why this is wrong here
Bluesnarfing is an attack against Bluetooth devices, not Wi-Fi networks. The question describes a wireless disconnection issue involving two access points with the same SSID, which is a Wi-Fi attack scenario.
★ When this WOULD be the correct answer
A user reports that their Bluetooth headset has been paired with an unknown device and they are experiencing audio dropouts. A security analyst discovers that an attacker is using a Bluetooth vulnerability to access the headset's contact list and call history. Bluesnarfing would be the correct answer.
Why candidates choose this
Candidates may confuse 'Bluetooth' with 'wireless' or think that any wireless attack involving unauthorized access is bluesnarfing, without recognizing that bluesnarfing specifically targets Bluetooth connections.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The N10-009 exam often tests the distinction between a rogue AP (an unauthorized device plugged into the wired network) and an evil twin (a standalone malicious AP that mimics the SSID without being connected to the corporate infrastructure), so candidates must remember that the key differentiator is the open security and different channel used to lure clients away from the legitimate AP.
Trap categories for this question
Scenario analysis trap
While a rogue AP is an unauthorized AP, the scenario specifically describes an AP that is spoofing the legitimate SSID with open security, which is an evil twin attack. 'Evil twin' is more precise.
Detailed technical explanation
How to think about this question
In an evil twin attack, the attacker typically uses a tool like airbase-ng to create a cloned AP with the same SSID but a different BSSID, often on a non-overlapping channel (e.g., channel 11 vs. channel 1) to maximize interference and force clients to roam. Clients may automatically connect to the stronger signal if they are configured to prefer signal strength over security, especially if the legitimate AP's signal is weaker. The attack exploits the lack of mutual authentication in WPA2-PSK or open networks, allowing the attacker to capture handshakes or plaintext traffic.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- 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 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.
