200-201 Security Monitoring Practice Question
A SIEM correlation rule triggers when more than 10 failed login attempts from a single source IP occur within 1 minute. This rule is designed to detect:
⚠ Common exam trap
Cisco often tests the distinction between a brute force attack (repeated failed logins) and a DDoS attack (high traffic volume), so candidates may confuse the two because both involve high event counts from a single source.
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
A brute force attack involves repeated login attempts using many password guesses. The SIEM rule specifically detects this pattern by counting failed logins from a single source IP within a short time window (1 minute). This matches the signature of an automated password guessing tool, not other attack types.
