The answer is the Microsoft Entra ID data connector. This connector is the correct choice because it is specifically designed to ingest both sign-in logs and audit logs from Microsoft Entra ID (formerly Azure Active Directory) directly into Microsoft Sentinel, providing the essential identity-based security events needed for SIEM analysis. On the Microsoft Cybersecurity Architect exam, this question tests your ability to distinguish between data connectors by their source scope; a common trap is confusing the Entra ID connector with the Office 365 connector, which ingests Exchange and SharePoint data, or the Azure Activity connector, which handles subscription-level resource events. A reliable memory tip is to associate "Entra ID" with "Identity and Access" logs—if the requirement mentions user sign-ins or directory audits, always choose the Entra ID connector, not the broader Office 365 or Defender XDR options.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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 company uses Microsoft Sentinel for SIEM. They need to ensure that security events from Azure Active Directory (now Microsoft Entra ID) are ingested into Sentinel. Which data connector should they enable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra ID connector
The Microsoft Entra ID connector (Option B) is the correct data source for ingesting sign-in logs and audit logs from Entra ID. Option A is wrong because the Office 365 connector ingests data from Exchange, SharePoint, etc. Option C is wrong because the Azure Activity connector ingests subscription-level events. Option D is wrong because the Microsoft Defender XDR connector ingests alerts from Defender products.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
