The answer is Azure Activity Logs, Azure SQL Database audit logs, and network security group flow logs. This combination is correct because to detect data exfiltration from Azure SQL Database with Sentinel, you need visibility into three distinct layers: the database queries themselves (audit logs), the resource management changes that could alter security controls (Activity Logs), and the actual network traffic patterns leaving the database subnet (NSG flow logs). On the Microsoft Cybersecurity Architect exam, this question tests your understanding of log source selection for specific threat scenarios—a common trap is choosing Azure AD sign-in logs, which track user authentication rather than database operations, or Microsoft Defender for Cloud alerts, which provide summarized threats but not the raw query or traffic data needed for exfiltration detection. A helpful memory tip is to think of the three "A's": Audit, Activity, and Access (network access via flow logs).
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
A financial services company uses Microsoft Sentinel for SIEM. They need to detect potential data exfiltration from their Azure SQL Database. Which THREE data sources should they connect to Sentinel to achieve this? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Network Watcher NSG flow logs
Azure SQL Database audit logs contain query details; Azure Activity Logs provide resource management events; Network security group flow logs show network traffic patterns. Option A, Option B, and Option C are correct. Option D is wrong because Azure AD sign-in logs are for user authentication, not database operations. Option E is wrong because Microsoft Defender for Cloud alerts may cover threats but not raw data exfiltration details.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Microsoft Defender for Cloud alerts
Why it's wrong here
Alerts may indicate security incidents, but for detailed detection, raw logs are needed.
✗
Azure AD sign-in logs
Why it's wrong here
Show user login events, not database-specific activities.
✓
Azure Network Watcher NSG flow logs
Why this is correct
Provide network traffic data to detect unusual data transfers.
Related concept
Static NAT maps one inside address to one outside address.
✓
Azure SQL Database audit logs
Why this is correct
Contain detailed SQL queries that can indicate data access patterns.
Related concept
Static NAT maps one inside address to one outside address.
✓
Azure Activity Logs
Why this is correct
Show administrative operations like export or backup that could indicate exfiltration.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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.
Trap categories for this question
Command / output trap
Show user login events, not database-specific activities.
Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
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 company uses Microsoft Sentinel for security operations. You need to design a solution that automatically remediates a detected threat by blocking a malicious IP address on Azure Firewall. Which Microsoft Sentinel feature should you use?
medium
A.Analytics rules
B.Workbooks
✓ C.SOAR playbooks
D.User and Entity Behavior Analytics (UEBA)
Why C: Option C is correct because Security Orchestration, Automation, and Response (SOAR) in Microsoft Sentinel uses playbooks to automate remediation actions like blocking IPs on Azure Firewall. Option A is wrong because analytics rules only generate alerts. Option B is wrong because workbooks visualize data. Option D is wrong because UEBA analyzes behavior but does not automate remediation.
Variation 2. A company uses Microsoft Sentinel for security operations. They want to collect logs from a custom application running on Azure Virtual Machines. The application writes logs to a local file. Which data connector should they use?
medium
A.Application Insights
B.Syslog
C.Windows Event Forwarding
✓ D.Custom Logs via Log Analytics agent
Why D: The Log Analytics agent (or Azure Monitor Agent) can collect custom log files from VMs. Option C is correct. Option A is wrong because Syslog is for Linux, but the application writes to a file, not syslog. Option B is wrong because Windows Event Log is for Windows event logs, not custom file logs. Option D is wrong because Application Insights is for application performance monitoring, not log file collection.
