Quick Answer
The answer is Azure Network Watcher, Microsoft Sentinel, and Azure Firewall logs. These three services work together to detect network threats by capturing traffic patterns, analyzing logs for suspicious activity, and monitoring firewall events for anomalies. Network Watcher provides packet capture and flow logs to visualize traffic, while Microsoft Sentinel ingests these logs for advanced threat detection using built-in analytics. Azure Firewall logs offer real-time visibility into allowed and denied traffic, enabling you to identify unauthorized access attempts. On the AZ-500 exam, this question tests your ability to distinguish monitoring services from compliance or performance tools—a common trap is choosing Azure Policy (compliance) or Azure Monitor Metrics (performance metrics), which do not detect network threats. Remember the mnemonic “SNF” for Sentinel, Network Watcher, and Firewall logs: think of a security guard (Sentinel) watching network flows (Network Watcher) while checking firewall records.
This AZ-500 practice question tests your understanding of secure networking. 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.
You need to monitor network traffic to detect anomalies and potential security threats. Which THREE Azure services can you use to achieve this? (Choose three.)
Microsoft Sentinel
Sentinel can analyze network logs for threats.
Azure Monitor Metrics
Why wrong: Metrics are for performance, not network traffic analysis.
Azure Firewall logs
Firewall logs contain traffic data that can be analyzed.
Azure Policy
Why wrong: Azure Policy is for governance, not monitoring.
Azure Network Watcher
Network Watcher provides packet capture and flow logs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Sentinel
Options A, B, and D are correct. Network Watcher provides traffic capture and flow logs. Azure Sentinel (now Microsoft Sentinel) can ingest network logs for threat detection. Azure Firewall logs can be used for monitoring. Option C is wrong because Azure Policy is for compliance, not monitoring. Option E is wrong because Azure Monitor Metrics can monitor performance, not network traffic anomalies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
