A security administrator discovers that an attacker has intercepted data between two legitimate hosts by redirecting traffic through a rogue device. Which type of attack is this?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
ARP poisoning
ARP poisoning is a technique often used to perform a man-in-the-middle attack, but it is not the attack itself. The question describes the overall effect (intercepting data), which is MITM.
B
Distractor review
DNS poisoning
DNS poisoning corrupts DNS records to redirect users to malicious sites. It does not typically involve direct interception between two hosts after a connection is established.
C
Best answer
Man-in-the-middle
The scenario describes an attacker intercepting communications between two hosts by inserting themselves in the path. This is the classic definition of a man-in-the-middle attack.
D
Distractor review
Replay attack
A replay attack involves capturing valid data transmissions and retransmitting them later to impersonate a user or cause a repeated action. It does not involve real-time interception.
Common exam trap
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.
Technical deep dive
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.
- Eliminate answers that are true in general but not in this case.
- 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.

FAQ
Questions learners often ask
What does this N10-009 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Man-in-the-middle — In a man-in-the-middle (MITM) attack, the attacker secretly relays and possibly alters communications between two parties who believe they are directly communicating. This allows interception of data.
