The answer is to enable the 'Azure Activity' data connector in Microsoft Sentinel. This connector is the most efficient method because it is purpose-built to stream all Azure subscription activity logs directly into Sentinel without requiring any additional infrastructure, manual exports, or custom scripting. It leverages the Azure Monitor backend to automatically pull operational data from the Azure Activity Log, covering management-plane events like resource creation, policy changes, and security alerts. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of native data ingestion methods versus unnecessary complexity—a common trap is assuming diagnostic settings alone suffice, but those export to a Log Analytics workspace, not directly into Sentinel’s security content. Another pitfall is over-engineering with Logic Apps when a simple connector exists. Remember the memory tip: “Activity needs a connector, not a diagnostic exporter.”
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company uses Microsoft Sentinel as a SIEM. You need to ensure that all Azure subscription activity logs are ingested into Sentinel. What is the most efficient way to configure this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable the 'Azure Activity' data connector in Sentinel.
Option B is correct because the data connector for Azure Activity is designed for this purpose. Option A is wrong because manual export is not efficient. Option C is wrong because diagnostic settings export to a Log Analytics workspace, but Sentinel requires the data connector. Option D is wrong because Logic Apps are unnecessary overhead.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure diagnostic settings on the subscription to send logs to a Log Analytics workspace.
Why it's wrong here
This sends logs but Sentinel needs a connector to ingest.
✗
Create an Azure Logic App to periodically pull activity logs.
Why it's wrong here
Logic App is inefficient and not needed.
✓
Enable the 'Azure Activity' data connector in Sentinel.
Why this is correct
This automatically streams activity logs.

✗
Manually export activity logs to a storage account and connect to Sentinel.
Why it's wrong here
Manual export is not efficient.
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
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
