The answer is the SecurityEvent table. This is correct because RDP connection events on a Windows virtual machine are captured as Windows Event ID 4624 within the Security log, which Microsoft Sentinel ingests directly via the SecurityEvent data source. When a compromised account initiates an RDP session, the SecurityEvent table records the logon type, source IP, and account details, making it the go-to table for investigating such incidents. On the SC-200 exam, this question tests your ability to differentiate between data connectors: the SecurityEvent table is for Windows security logs, while CommonSecurityLog handles network appliances, SigninLogs covers Azure AD authentication, and DeviceEvents is for Defender for Endpoint advanced hunting but is not ingested into Sentinel by default. A common trap is confusing the SecurityEvent table with Defender for Endpoint’s DeviceEvents, but remember that RDP logs are native Windows security events, not endpoint detection alerts. Memory tip: think “4624 for the door” — Event ID 4624 always means someone opened the RDP door.
SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
During an incident investigation, you find that a compromised account was used to log into a virtual machine via RDP from an IP address in a sanctioned country. The VM has Microsoft Defender for Endpoint installed. Which data source in Microsoft Sentinel would you query to see the RDP connection events?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SecurityEvent
Option C is correct because RDP connection events on a Windows machine are captured in the SecurityEvent table (Event ID 4624). Option A is for network traffic logs. Option B is for audit logs from Azure AD. Option D is for advanced hunting in Defender for Endpoint, but not directly ingested into Sentinel by default.
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.
✗
DeviceLogonEvents (Microsoft Defender XDR)
Why it's wrong here
DeviceLogonEvents is from Microsoft Defender for Endpoint advanced hunting, not directly in Sentinel unless streamed.
✗
CommonSecurityLog
Why it's wrong here
CommonSecurityLog typically contains logs from third-party security appliances, not Windows RDP events.
✗
SigninLogs (Microsoft Entra ID)
Why it's wrong here
SigninLogs show cloud application sign-ins, not RDP logons to a VM.
✓
SecurityEvent
Why this is correct
SecurityEvent collects Windows security events including RDP logons (Event ID 4624) when configured.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
