- A
Dictionary attack
Why wrong: Dictionary uses common passwords, but the pattern of repeated failures then success could be either; brute-force is more generic.
- B
Man-in-the-middle attack
Why wrong: MITM intercepts communications, does not generate many failed logins.
- C
Brute-force attack
Brute-force tries all possible combinations until success, matching the log pattern.
- D
Replay attack
Why wrong: Replay involves resending captured authentication packets, not many failed attempts.
- E
Password spraying attack
Why wrong: Spraying uses a few passwords against many accounts, not many attempts from one IP.

This SSCP practice question tests your understanding of sscp exam topics. 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 security audit, an analyst finds that a server's audit log shows repeated failed login attempts from a single IP, followed by a successful login from the same IP five minutes later. What is the most likely type of attack that occurred?
Clue words in this question

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
✓
Brute-force attack
The correct answer is Option C (brute-force attack). The scenario describes repeated failed login attempts from a single IP address followed by a successful login, which is characteristic of a brute-force attack where an attacker tries many passwords until one works. Option A (dictionary attack) uses a list of likely passwords but may not be as exhaustive; the description of repeated attempts without specifying a list suggests brute-force. Option B (man-in-the-middle attack) intercepts communications, not login attempts. Option D (replay attack) involves capturing and reusing a valid credential, not repeated tries. Option E (password spraying attack) targets multiple accounts with a few common passwords, not repeated attempts on a single account from one IP.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
