The answer is Windows Security Events (Event ID 4624) because this event captures successful logon attempts, and when paired with LogonType 3 (network logon), it reveals the use of hashed credentials characteristic of pass-the-hash attacks. To detect pass-the-hash attacks with Microsoft Sentinel data sources, you must prioritize authentication logs that expose credential reuse over the network, and Event ID 4624 is the only native Windows log that records both the logon type and the hashed authentication method. On the Microsoft Cybersecurity Architect exam, this question tests your ability to distinguish between data sources that capture identity-level events versus infrastructure or process-level logs—a common trap is confusing Sysmon Event ID 1 (process creation) with authentication events. Remember that lateral movement via pass-the-hash always leaves a network logon footprint, so focus on LogonType 3 with Event ID 4624. Memory tip: “4624 for the door, LogonType 3 for the key.”
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Your organization uses Microsoft Sentinel to monitor hybrid workloads. You need to design a solution to detect lateral movement attempts using pass-the-hash attacks. Which data source should you prioritize for ingestion?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Windows Security Events (Event ID 4624)
Option B is correct because Windows Security Event ID 4624 (successful logon) with LogonType 3 (network) and hashed credentials is key for detecting pass-the-hash. Option A is wrong because Azure Activity Logs record control plane events, not authentication details. Option C is wrong because Sysmon Event ID 1 is process creation, not authentication. Option D is wrong because DNS logs may show network connections but not credential theft.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Sysmon Event ID 1 (Process creation)
Why it's wrong here
Process creation events may show suspicious processes but do not directly indicate pass-the-hash.
✗
DNS Query Logs
Why it's wrong here
DNS logs show network queries but not authentication credential reuse.
✗
Azure Activity Logs
Why it's wrong here
Azure Activity Logs record resource management events, not authentication details needed for pass-the-hash.
✓
Windows Security Events (Event ID 4624)
Why this is correct
Event ID 4624 captures successful logons with logon type and credential details, critical for detecting pass-the-hash.

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 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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your organization uses Microsoft Sentinel for security operations. You need to design a solution to detect and respond to lateral movement using pass-the-hash attacks. Which TWO data sources should you enable for ingestion into Microsoft Sentinel to detect such attacks?
medium
✓ A.Microsoft Defender for Identity alerts.
B.DNS events from DNS servers.
C.Azure AD sign-in logs.
✓ D.Windows Security Events (Event ID 4624) from domain controllers.
E.Sysmon logs for process creation.
Why A: Correct answers: A and D. Windows Security Events (Event ID 4624) can show anomalous logons, and Microsoft Defender for Identity provides detection of pass-the-hash. Option B is incorrect: Azure AD sign-in logs do not capture on-prem NTLM events. Option C is incorrect: Sysmon is helpful but not specifically for pass-the-hash. Option E is incorrect: DNS logs are for network anomalies.
Variation 2. Your organization uses Microsoft Sentinel for security operations. You need to design a solution to detect and respond to lateral movement attempts using pass-the-hash attacks. Which TWO data sources should you enable in Microsoft Sentinel to best detect this activity?
easy
A.Office 365 Audit Logs
✓ B.Windows Security Events via Azure Monitor Agent
C.DNS query logs
✓ D.Microsoft Defender for Identity alerts
E.Azure Activity Log
Why B: Option A (Windows Security Events) logs NTLM authentication events that can reveal pass-the-hash attempts. Option D (Microsoft Defender for Identity) provides advanced behavioral analytics to detect lateral movement. Option B (Azure Activity) is for Azure resource operations, not on-premises lateral movement. Option C (Office 365) is for cloud app activity. Option E (DNS) helps with network detection but is not the best for pass-the-hash.
