Quick Answer
The answer is the Amazon Web Services S3 connector. This is the correct built-in connector in Microsoft Sentinel for ingesting AWS logs because it leverages an S3 bucket as an intermediary: AWS services like CloudTrail, VPC Flow Logs, and GuardDuty are configured to export their logs to a designated S3 bucket, and Sentinel then polls that bucket via the S3 REST API using a cross-account IAM role for secure, automated ingestion. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of native, agentless data connectors versus third-party or custom solutions—a common trap is confusing the AWS S3 connector with the Azure Monitor Agent or a Logic App-based workaround. Remember that Sentinel’s built-in AWS integration is fundamentally storage-driven, not stream-based. A useful memory tip: think “S3 as the staging ground”—if logs land in an S3 bucket, Sentinel can pull them in natively.
This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. 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 and wants to use a built-in connector to ingest logs from Amazon Web Services (AWS). Which connector should they use?
ServiceNow connector
Why wrong: ServiceNow is for ITSM integration.
Azure Policy for AWS
Why wrong: Azure Policy does not apply to AWS.
Office 365 connector
Why wrong: Office 365 is for Microsoft 365 logs.
Amazon Web Services S3 connector
This is the built-in connector for AWS logs.

Correct answer & explanation
Amazon Web Services S3 connector
The Amazon Web Services (AWS) S3 connector is the correct built-in connector in Microsoft Sentinel for ingesting logs from AWS. It works by configuring AWS to send logs (such as CloudTrail, VPC Flow Logs, or GuardDuty findings) to an S3 bucket, which Sentinel then polls via the S3 REST API using an IAM role for secure, cross-account access. This is the native, supported method for log ingestion from AWS into Sentinel.
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.
ServiceNow connector
Why it's wrong here
ServiceNow is for ITSM integration.
Azure Policy for AWS
Why it's wrong here
Azure Policy does not apply to AWS.
Office 365 connector
Why it's wrong here
Office 365 is for Microsoft 365 logs.
Amazon Web Services S3 connector
Why this is correct
This is the built-in connector for AWS logs.

Common exam traps
The trap here is that candidates may confuse Azure Policy for AWS (which is a governance tool, not a log ingestion connector) with a valid data source, or assume that a generic connector like ServiceNow could be adapted for AWS log ingestion, when only the AWS S3 connector is the built-in, purpose-built option.
Detailed technical explanation
The AWS S3 connector uses an IAM role with a trust policy that allows Sentinel's AWS account (provided by Microsoft) to assume the role and read objects from the specified S3 bucket. The connector supports multiple log types by configuring separate data collection rules in Sentinel, and it uses SQS (Simple Queue Service) notifications to trigger near-real-time ingestion rather than relying solely on periodic polling. A common real-world scenario is ingesting AWS CloudTrail logs for user activity monitoring, where the S3 bucket must have the correct bucket policy to allow cross-account access from Microsoft's AWS account ID.
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.
