Quick Answer
The answer is Azure Active Directory sign-in logs and Windows Security Events. These two data sources are essential for credential theft detection because Windows Security Events capture critical authentication-related activities like failed logon attempts, privilege escalation, and pass-the-hash attacks directly from domain controllers and endpoints, while Azure AD sign-in logs provide visibility into cloud-based authentication patterns, including anomalous sign-in locations, impossible travel, and brute-force attempts. On the SC-200 exam, this tests your ability to distinguish between security-relevant logs and network-level or performance data—a common trap is choosing firewall or DNS logs, which are useful for network forensics but do not directly reveal credential theft. Remember the mnemonic “Signs and Events” to link sign-in logs with security events, and always ask yourself whether a data source captures authentication behavior or just network traffic.
This SC-200 practice question tests your understanding of respond to security incidents. 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.
Which TWO data sources should you enable in Microsoft Sentinel to improve detection of credential theft attacks?
Windows Security Events (via AMA)
Contains Event ID 4625 (failed logon) and 4648 (explicit credential).
DNS logs
Why wrong: Not directly related.
Azure Active Directory Sign-in logs
Shows sign-in attempts and anomalies.
Windows Firewall logs
Why wrong: Network-level, not credential theft.
Performance counters
Why wrong: Not security-related.
Answer choices
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 (via AMA)
Option A is correct because Windows Security Events contain credential theft logs. Option B is correct because Azure AD Sign-in logs show authentication patterns. Option C is wrong because firewall logs are network-level. Option D is wrong because DNS logs are not directly credential theft. Option E is wrong because performance counters are not security-related.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis

Not security-related.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SC-200 NAT questions on configuration and troubleshooting.
