- A
Microsoft Sentinel
Microsoft Sentinel is a scalable, cloud-native SIEM and SOAR that can ingest logs from on-premises, Azure, AWS, GCP, and many other sources. It provides threat detection and automated response via playbooks, making it the correct solution for the described need.
- B
Microsoft Defender for Cloud
Why wrong: Microsoft Defender for Cloud primarily provides posture management and workload protection for Azure and hybrid resources. It does not offer the multi-cloud log aggregation, advanced SIEM analytics, or SOAR playbook automation that Sentinel provides.
- C
Microsoft Defender for Identity
Why wrong: Microsoft Defender for Identity is an on-premises Active Directory security solution that detects threats like lateral movement and compromised identities. It does not ingest logs from AWS or GCP and lacks broad SOAR capabilities.
- D
Microsoft Cloud App Security
Why wrong: Microsoft Cloud App Security is a CASB that focuses on SaaS applications (e.g., Salesforce, Box). It does not provide infrastructure log collection from clouds like AWS or GCP, nor does it serve as a full SIEM for all security events.
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.
A global enterprise has a hybrid environment that includes on-premises Active Directory, Azure resources, Amazon Web Services (AWS), and Google Cloud Platform (GCP). The security team needs a single solution to collect security logs from all these sources, detect threats using advanced analytics and threat intelligence, and automate incident response via playbooks. They already have Microsoft Defender for Cloud protecting their Azure workloads. Which Microsoft security solution should they add to meet these requirements?

Correct answer & explanation
Microsoft Sentinel
Microsoft Sentinel is a cloud-native SIEM and SOAR solution that ingests logs from a wide range of sources, including on-premises, Azure, AWS, and GCP. It provides advanced analytics, threat detection, and automated response through playbooks. Microsoft Defender for Cloud is a cloud security posture management (CSPM) and workload protection solution; while it does collect some logs and can send alerts to Sentinel, it does not provide the full SIEM/SOAR capabilities needed for multi-cloud aggregation and automation beyond Azure. Microsoft Defender for Identity focuses on on-premises AD threats but not multi-cloud. Microsoft Cloud App Security is a CASB for SaaS apps, not a SIEM for infrastructure logs.
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- 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
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.
