Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
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?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
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
Distractor review
Microsoft Defender for Cloud
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
Distractor review
Microsoft Defender for Identity
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
Distractor review
Microsoft Cloud App Security
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.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SC-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: 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.
