Amazon Web Services SAA-C03 Exam With Confidence Using Practice Dumps

The first step is to configure a delegated administrator account for IAM Access Analyzer at the organization level. Only after delegating the administrator account can you aggregate Access Analyzer findings from all member accounts into a designated audit account. This must be set up in the AWS Organizations management account.

AWS Documentation Extract:

“You must designate a delegated administrator for IAM Access Analyzer at the organization level. The delegated administrator account aggregates findings from all member accounts.”

A, C, D: These steps do not establish the organization-wide aggregation required for Access Analyzer.

Amazon FSx for Lustre is a high-performance parallel file system designed for machine learning and HPC that can be linked to Amazon S3 via Data Repository Associations (DRA). With DRA, you can import S3 objects as files (lazy or preloaded) and export results back to S3, providing very high throughput and low-latency POSIX access on the training cluster. This S3-native integration minimizes data loading overhead and accelerates training cycles at scale. EFS (A) is general-purpose and lower throughput per TB than Lustre. EBS (C) requires manual copy and does not scale as a shared parallel filesystem. DataSync alone (D) is a transfer tool, not a high-throughput training filesystem. FSx for Lustre with S3 DRA best satisfies scalability, throughput, and native S3 integration for rapid ML training.

Step A:AWS WAF with managed rules protects the API against application-layer attacks, such as SQL injection and cross-site scripting (XSS).

Step C:Amazon Cognito provides secure authentication and supports federation with social IdPs using OIDC or SAML. It integrates seamlessly with API Gateway.

Option B:AWS Shield Advanced provides DDoS protection, which is not explicitly required in this scenario.

Option D:API keys provide identification, not authentication, and are insufficient for this use case.

Option E:IP filters in WAF are overly restrictive for federated authentication scenarios.
