The correct answer is to useIAM roles with fine-grained permissions. AWS recommends temporary credentials and least-privilege access instead of shared accounts or long-term access keys. Assigning a separate role to each developer gives the company strong access isolation, simpler auditing, and the ability to restrict each developer to only the AWS actions they need. Shared IAM user credentials are insecure because actions cannot be tied reliably to one person. Long-term access keys increase credential management risk. Amazon Cognito is primarily for application end users, not for granting internal developers administrative access to AWS resources. Using IAM roles is the standard AWS security best practice for controlled workforce access.

Amazon S3 File Gateway (AWS Storage Gateway) exposes an on-premises NFS/SMB file share that durably stores files as S3 objects with local caching, enabling low-latency writes on-premises and asynchronous, near-real-time ingestion into Amazon S3 for analytics. It is purpose-built to “present a file interface backed by Amazon S3” and to “store files as objects in your S3 buckets,” so existing applications writing to a network share can transparently land data in S3 without custom scripts or job orchestration. Compared with scheduled transfers (e.g., end-of-day DataSync), S3 File Gateway continuously uploads new/changed files, better meeting the near-real-time requirement. Transfer Family (SFTP) would require custom polling and client changes, increasing operational burden. DataSync is excellent for bulk or periodic migrations/synchronizations but is not as seamless for continuous ingestion from a live file share. Therefore, updating the application to point to an S3 File Gateway share provides the simplest, performant path to near-real-time delivery into S3 for downstream analytics.

Amazon Macieis purpose-built for detecting PII in S3.

Option Auses EventBridge to filter SensitiveData findings and notify via SNS, meeting the requirements.

Options B and Dinvolve GuardDuty, which is not designed for PII detection.

Option Cuses SQS, which is less suitable for immediate notifications.
