This CEH practice question tests your understanding of malware, social engineering and network attacks. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 penetration test, a tester uses a tool to perform ARP spoofing to intercept traffic between two hosts on the same subnet. Which tool is most commonly associated with this technique?
Wireshark
Why wrong: Wireshark is a packet analyzer, not used for active spoofing.
Ettercap
Ettercap specializes in ARP spoofing and MITM attacks.
Metasploit
Why wrong: Metasploit is an exploitation framework; ARP spoofing is not its primary function.
Nmap
Why wrong: Nmap is a network scanner, not an ARP spoofing tool.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Ettercap
Ettercap is a well-known tool for ARP poisoning (spoofing) to perform man-in-the-middle attacks. It is specifically designed for this purpose.
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.
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.
