Full question →mediummultiple choiceObjective-mapped
A security operations center (SOC) team needs to collect security logs from Azure services, on-premises servers, and third-party firewalls. They want a cloud-native solution that provides advanced threat detection through analytics, machine learning, and the ability to hunt for threats across all data sources. Which Microsoft solution should they deploy?
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
Distractor review
Microsoft Defender for Cloud
Microsoft Defender for Cloud provides cloud security posture management (CSPM) and workload protection, but it is not a full SIEM that aggregates logs from on-premises and third-party sources.
B
Distractor review
Microsoft 365 Defender
Microsoft 365 Defender is an extended detection and response (XDR) solution for Microsoft 365 ecosystem (endpoints, email, identity, etc.). It does not serve as a primary SIEM for multi-source, cross-platform log collection.
C
Best answer
Microsoft Sentinel
Microsoft Sentinel is a scalable, cloud-native SIEM that collects data from any source, applies analytics and machine learning for threat detection, and supports proactive threat hunting.
D
Distractor review
Microsoft Defender for Identity
Microsoft Defender for Identity uses on-premises Active Directory signals to detect identity-based attacks. It is not a general SIEM for diverse log sources.
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.
