Quick Answer
The answer is Microsoft Sentinel, the correct choice because it is a cloud-native SIEM solution architected for multi-source log ingestion from on-premises servers, Azure resources, and third-party SaaS applications through its extensive library of over 100 built-in data connectors. This technical capability allows Sentinel to aggregate disparate log formats into a unified workspace, enabling centralized security analytics and automated incident response without requiring custom parsing. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how Sentinel’s native integration with Azure Monitor, Microsoft 365 Defender, and third-party APIs fulfills the requirement for ingesting logs from multiple sources, often appearing as a distractor against Azure Log Analytics (which lacks SIEM features) or Azure Sentinel’s predecessor, OMS. A common trap is confusing Log Analytics workspaces with Sentinel’s full SIEM functionality—remember that Sentinel is Log Analytics plus security orchestration. Memory tip: Think of Sentinel as the “single pane of glass” for all logs, with connectors acting as the pipes that bring every source into one lake.
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. 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.
Your organization wants to implement a security information and event management (SIEM) solution that can ingest logs from multiple sources, including on-premises servers, Azure resources, and third-party SaaS applications. Which Microsoft service should you choose?
Microsoft Purview
Why wrong: Purview is for data governance, compliance, and risk management.
Microsoft Defender for Cloud
Why wrong: Defender for Cloud provides security recommendations and workload protection, not SIEM.
Microsoft Sentinel
Sentinel is a scalable SIEM for log ingestion from diverse sources.
Azure Monitor
Why wrong: Azure Monitor is for performance monitoring, not SIEM.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Sentinel
Microsoft Sentinel is the correct choice because it is a cloud-native SIEM solution specifically designed to ingest logs from diverse sources, including on-premises servers, Azure resources, and third-party SaaS applications, using built-in connectors for over 100 data sources. It provides centralized security analytics, threat detection, and incident response, making it the appropriate service for this multi-source log ingestion requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Microsoft Purview
Why it's wrong here
Purview is for data governance, compliance, and risk management.
Microsoft Defender for Cloud
Why it's wrong here
Defender for Cloud provides security recommendations and workload protection, not SIEM.
Microsoft Sentinel
Why this is correct
Sentinel is a scalable SIEM for log ingestion from diverse sources.

Azure Monitor
Why it's wrong here
Azure Monitor is for performance monitoring, not SIEM.
Common exam traps
The trap here is that candidates often confuse Azure Monitor with a SIEM because it collects logs and metrics, but it lacks the security-specific correlation, threat intelligence integration, and incident management features that define a true SIEM like Microsoft Sentinel.
Detailed technical explanation
Microsoft Sentinel uses Log Analytics workspaces as its underlying data store, leveraging the Kusto Query Language (KQL) for advanced analytics and threat hunting. It supports data ingestion via Log Analytics agents, Syslog, Common Event Format (CEF), and REST APIs, enabling integration with sources like AWS CloudTrail, Google Cloud Platform, and SaaS apps such as Office 365 and Salesforce. A real-world scenario where this matters is when an organization needs to correlate a suspicious login from a SaaS app with an on-premises server event to detect a lateral movement attack, which Sentinel's fusion engine can automate using built-in analytics rules.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
