- A
The rogue AP may cause radio frequency interference with the corporate WLAN.
Why wrong: While interference is possible, the immediate security risk of unauthorized network access is far more critical.
- B
The rogue AP provides an unencrypted entry point for attackers to access the corporate network.
An open SSID means no encryption or authentication, allowing anyone to connect and potentially launch attacks or access sensitive data.
- C
The rogue AP will consume additional power from the corporate UPS.
Why wrong: Power consumption is a minor operational concern, not a security risk.
- D
The rogue AP's DHCP server may conflict with the corporate DHCP server.
Why wrong: DHCP conflicts can cause IP address issues, but the primary concern is the security breach from an open network.
Quick Answer
The answer is that the rogue access point provides an unencrypted entry point for attackers to access the corporate network. This is the most immediate security risk because an open SSID broadcasts a wireless signal with no encryption, allowing anyone within range to connect to the corporate network without any authentication, effectively bypassing all perimeter security controls like firewalls and NAC. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of rogue AP risks and the critical importance of enforcing wireless security policies; a common trap is focusing on bandwidth theft or interference rather than the direct, unguarded network access. Remember the memory tip: “Open AP equals open door”—if the SSID is open, the network is exposed, making it a severe security incident that demands immediate remediation.
220-1102 Wireless Security Protocols Practice Question
This 220-1202 practice question tests your understanding of wireless security protocols. 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.
During a wireless site survey, a technician discovers that an employee has set up a personal wireless router in their cubicle, connected to the corporate network. This rogue access point is broadcasting an open SSID. Which security risk is most immediately concerning?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The rogue AP provides an unencrypted entry point for attackers to access the corporate network.
An open rogue access point allows anyone within range to connect to the corporate network without authentication, bypassing all security controls. This is a severe security incident. The question tests knowledge of rogue AP risks and the importance of wireless security policies.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The rogue AP may cause radio frequency interference with the corporate WLAN.
Why it's wrong here
While interference is possible, the immediate security risk of unauthorized network access is far more critical.
- ✓
The rogue AP provides an unencrypted entry point for attackers to access the corporate network.
Why this is correct
An open SSID means no encryption or authentication, allowing anyone to connect and potentially launch attacks or access sensitive data.
Clue confirmation

Why it's wrong here
DHCP conflicts can cause IP address issues, but the primary concern is the security breach from an open network.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
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
How to think about this question
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.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
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
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.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 220-1202 subnetting questions on CIDR, address ranges, and subnet selection.
