200-201 A SOC analyst at a medium-sized enterprise Practice Question

You are a SOC analyst at a medium-sized enterprise. The company uses a SIEM that collects logs from firewalls, endpoints, and Active Directory. At 2:00 AM, the SIEM generates a high-priority alert: 'Multiple Failed Logins for Administrator Account from Remote IP 198.51.100.20'. The analyst on the night shift reviews the alert and sees that there were 50 failed attempts in 10 minutes, followed by a successful login at 2:12 AM. The successful login originated from the same IP. The account is a domain administrator. The analyst checks the firewall logs and sees that the IP is from a known VPN provider. The analyst also checks the endpoint logs and sees that no unusual activity has occurred after the login. The company has a policy that remote administration is allowed only from a specific jump server with IP 203.0.113.10. The analyst suspects a brute-force attack succeeded. What should the analyst do first?

⚠ Common exam trap

Cisco often tests the distinction between containment (disabling the account) and remediation (resetting the password), where candidates mistakenly choose password reset first because they think it solves the problem, but disabling is the correct immediate action to cut off access.

Correct answer & explanation

Disable the compromised administrator account immediately

The immediate priority is to contain the breach by disabling the compromised domain administrator account. The successful login from an unauthorized IP (198.51.100.20) after 50 failed attempts indicates a successful brute-force attack, and the account has domain-level privileges. Disabling the account stops any further lateral movement or privilege escalation, which is the first step in incident response containment before any remediation or investigation.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Block the IP address 198.51.100.20 on the firewall

    Why it's wrong here

    Blocking the IP is reactive, but the attacker may have already used that session to move laterally.

  • Disable the compromised administrator account immediately

    Why this is correct

    Disabling the account stops all access by the attacker and is the fastest containment action.

  • Perform a full network scan of the VPN provider's entire IP range

    Why it's wrong here

    Scanning the VPN provider's range is inefficient and could be considered aggressive; it does not address the immediate threat.

  • Reset the password of the compromised administrator account

    Why it's wrong here

    Resetting the password is important, but it does not terminate the current session immediately; disabling the account is more urgent.
