- 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.
Quick Answer
The answer is Microsoft Sentinel, because it is the only Microsoft security solution that combines SIEM and SOAR capabilities to collect security logs from Azure, AWS, and GCP in a multi-cloud environment. While Microsoft Defender for Cloud protects Azure workloads, it lacks the full log ingestion and automated incident response needed for a hybrid, multi-cloud setup. Sentinel ingests data from on-premises Active Directory, Azure, AWS, and GCP, then applies advanced analytics and threat intelligence to detect threats, and uses playbooks to automate response. On the SC-900 exam, this question tests your understanding of the difference between a SIEM/SOAR (Sentinel) and a CSPM/workload protection tool (Defender for Cloud). A common trap is confusing Defender for Cloud’s limited log collection with Sentinel’s comprehensive aggregation across clouds. Memory tip: Think “Sentinel sees all clouds and responds automatically,” while Defender for Cloud only defends Azure.
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: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.
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.
