Full question →mediummultiple choiceObjective-mapped
A company uses a mix of Azure virtual machines and on-premises Windows and Linux servers. The security team wants a single, integrated solution that can continuously assess these servers for missing security updates, weak operating system configurations, and common vulnerabilities. The solution should provide prioritized remediation recommendations. Which Microsoft security solution should they use?
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 Defender for Cloud
Correct. Defender for Cloud provides integrated vulnerability assessment and security posture management for Azure, on-premises, and multi-cloud workloads, including patch and configuration recommendations.
B
Distractor review
Microsoft Sentinel
Microsoft Sentinel is a cloud-native SIEM/SOAR platform. It can ingest vulnerability data from other sources but does not natively perform vulnerability scanning of servers.
C
Distractor review
Microsoft Defender for Identity
Microsoft Defender for Identity is an identity-based threat detection solution that monitors on-premises Active Directory for attacks. It does not perform OS-level vulnerability scanning.
D
Distractor review
Microsoft 365 Defender
Microsoft 365 Defender correlates signals from endpoints, email, identity, and cloud apps but does not directly scan server operating systems for vulnerabilities.
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 Defender for Cloud — Microsoft Defender for Cloud (formerly known as Azure Security Center and Azure Defender) provides unified security management and threat protection across hybrid cloud workloads. It includes integrated vulnerability assessment agents that scan VMs and servers for missing patches, misconfigurations, and vulnerabilities. Microsoft Sentinel is a SIEM/SOAR solution for threat detection and response, not primarily for vulnerability assessment. Microsoft Defender for Identity is focused on detecting identity-based attacks using on-premises Active Directory signals. Microsoft 365 Defender is a unified pre- and post-breach enterprise defense suite for endpoints, email, identity, and cloud apps, but does not natively perform OS-level vulnerability scanning on Azure VMs and on-premises servers. Therefore, Microsoft Defender for Cloud is the correct solution.
