- A
Review Microsoft Defender for Identity alerts for brute force attempts.
Why wrong: Brute force alerts are not directly related to Golden Ticket attacks.
- B
Check the domain controller's Security event log for Event ID 4769 with suspicious attributes.
Event ID 4769 logs Kerberos service ticket requests; anomalous entries can indicate forged tickets.
- C
Reset the krbtgt account password twice.
Why wrong: Resetting krbtgt twice is a remediation step after validation, not a validation step.
- D
Verify if the user account associated with the ticket is disabled.
Why wrong: A disabled account could be a sign, but the primary validation is through event logs.

SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. 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.
A security administrator receives an alert from Microsoft Defender for Identity about a suspicious Kerberos ticket request from a domain controller. The alert suggests a possible Golden Ticket attack. Which action should the administrator take to validate the alert?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the domain controller's Security event log for Event ID 4769 with suspicious attributes.
Event ID 4769 (Kerberos Service Ticket Request) on a domain controller is the authoritative source for validating suspicious ticket requests. In a Golden Ticket attack, the forged ticket often exhibits anomalous attributes such as an unusually long lifetime, a non-existent or disabled user account, or encryption type mismatches (e.g., RC4 when AES is expected). Reviewing this log directly confirms whether the ticket characteristics deviate from normal Kerberos behavior, providing definitive evidence for the alert.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

- ✗
Reset the krbtgt account password twice.
Why it's wrong here
Resetting krbtgt twice is a remediation step after validation, not a validation step.
- ✗
Verify if the user account associated with the ticket is disabled.
Why it's wrong here
A disabled account could be a sign, but the primary validation is through event logs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse validation steps with remediation actions, specifically choosing to reset the krbtgt password (Option C) before confirming the attack through log analysis, which would destroy forensic evidence and fail to validate the alert.
Detailed technical explanation
How to think about this question
Golden Ticket attacks exploit the KRBTGT account's NTLM hash to forge TGTs, which are then used to request service tickets (TGS) for any resource. Event ID 4769 logs the TGS request and includes fields such as Ticket Options, Ticket Encryption Type, and Service Name; a forged ticket often uses an encryption type (e.g., 0x17 for RC4) that does not match the domain's configured Kerberos encryption types. In real-world scenarios, attackers may also set the ticket lifetime to the maximum allowed (e.g., 10 years), which appears in the log as an abnormally long duration.
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.
TExam Day Tips
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
