Quick Answer
The answer is the AWS S3 connector. This is the correct choice because it is the native Microsoft Sentinel data connector designed specifically to ingest AWS CloudTrail logs and other AWS service logs from an S3 bucket, using an AWS Simple Queue Service (SQS) to poll for new log files and stream them into Sentinel for analysis. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of multi-cloud log ingestion architecture, often appearing as a scenario where you must select the proper connector for AWS logs; a common trap is confusing the AWS S3 connector with the Azure Activity Log connector or assuming a third-party solution is required. Remember the key pairing: S3 for storage, SQS for polling, and Sentinel for ingestion—think “S3 to SQS to Sentinel” as your memory anchor for this multi-cloud threat detection pipeline.
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 uses Microsoft Sentinel to centralize security logs from multiple clouds. They need to ensure that logs from Amazon Web Services (AWS) are ingested and analyzed for threats. Which connector should you implement?
Microsoft Defender for Cloud
Why wrong: Defender for Cloud does not ingest AWS logs natively.
Azure Monitor Agent
Why wrong: AMA collects logs from Azure VMs, not AWS.
AWS S3 connector
The AWS S3 connector ingests CloudTrail logs into Sentinel.
Azure Event Hubs
Why wrong: Event Hubs is an ingestion pipeline, not a connector for AWS.

Correct answer & explanation
AWS S3 connector
The AWS S3 connector is the correct choice because it is the native Microsoft Sentinel data connector designed specifically to ingest AWS CloudTrail logs (and other AWS service logs) from an S3 bucket. It uses an AWS Simple Queue Service (SQS) to poll for new log files, then streams them into Sentinel for analysis, enabling threat detection across multi-cloud environments.
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 Defender for Cloud
Why it's wrong here
Defender for Cloud does not ingest AWS logs natively.
Azure Monitor Agent
Why it's wrong here
AMA collects logs from Azure VMs, not AWS.
AWS S3 connector
Why this is correct
The AWS S3 connector ingests CloudTrail logs into Sentinel.

Azure Event Hubs
Why it's wrong here
Event Hubs is an ingestion pipeline, not a connector for AWS.
Common exam traps
The trap here is that candidates may confuse Microsoft Defender for Cloud (a security posture tool) with a log ingestion connector, or assume Azure Event Hubs is the default streaming solution for all external logs, overlooking the purpose-built AWS S3 connector that handles the specific S3-to-Sentinel pipeline.
Detailed technical explanation
The AWS S3 connector leverages an AWS Lambda function triggered by S3 bucket events to push log file references into an SQS queue, which Sentinel's polling agent then reads. This decoupled architecture ensures reliable, near-real-time ingestion without requiring Sentinel to have direct network access to the S3 bucket. A subtle behavior is that the connector supports multiple log types (CloudTrail, VPC Flow Logs, etc.) but each requires a separate data source configuration in Sentinel.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
