The answer is Syslog, CEF, and Microsoft Sentinel Data Connectors. Syslog is a standard protocol used by network devices to forward event messages, making it the universal method for log collection from third-party firewalls. Common Event Format (CEF) builds on Syslog by providing a structured, vendor-neutral schema that security devices like firewalls use to normalize log data for SIEM ingestion. Microsoft Sentinel Data Connectors offer pre-built integrations for popular firewall vendors, simplifying the configuration process. On the SC-900 exam, this question tests your understanding of log ingestion sources versus management tools—a common trap is confusing Azure Monitor Agent (designed for VM telemetry) or Microsoft Defender for Cloud (a posture management solution) with actual log collection methods. Remember the memory tip: "Syslog sends it, CEF formats it, Connectors wire it"—three distinct layers that work together for firewall log ingestion.
SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.
Your company uses Microsoft Sentinel as a SIEM. You need to collect logs from a third-party firewall. Which THREE methods can you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Common Event Format (CEF)
Options A, C, and D are correct. Syslog (A) is a standard protocol for log forwarding. CEF (C) is a common log format for security devices. Microsoft Sentinel Data Connectors (D) often include built-in connectors for common firewalls. Option B is wrong because Azure Monitor Agent is for Windows/Linux VMs, not network appliances. Option E is wrong because Microsoft Defender for Cloud is a security posture management tool, not a log collection method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.

Use explanations to understand the rule behind the answer.
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.
