Amazon Web Services Updated SAA-C03 Exam Questions and Answers by judah

AWS Transfer Family is a fully managed service that provides SFTP, FTPS, and FTP access directly to Amazon S3. It allows organizations to support legacy data transfer protocols without managing infrastructure. This approach gives the vendors a familiar SFTP interface, with files landing directly in S3, and requires minimal operational effort compared to managing EC2 servers or using gateways.

Reference Extract from AWS Documentation / Study Guide:

" AWS Transfer Family enables secure transfer of files directly into and out of Amazon S3 using SFTP, FTPS, and FTP, and is fully managed by AWS, significantly reducing operational overhead. "

TheAWS_PROXY integration with Amazon API Gatewayallows the API to invoke a Lambda function synchronously, making it a suitable solution for the custom authorization mechanism and text translation use case.

Synchronous Invocation: The API Gateway REST API with AWS_PROXY integration enables synchronous processing of HTTP requests and responses, which is required for document translation.

Custom Authorization: API Gateway supports custom authorizers for fine-grained access control.

Lambda Function Execution: Although Lambda ' s execution time limit is 15 minutes, this is sufficient for the 6-minute document translation requirement.

Why Other Options Are Not Ideal:

Option B:

Introducing a Lambda function URL to invoke another Lambda function unnecessarily complicates the architecture.Not efficient.

Option C:

Asynchronous invocation cannot guarantee real-time response delivery for document translation tasks.Not suitable.

Option D:

Hosting the API on an EC2 instance increases operational overhead. HTTP PROXY integration does not add significant benefits here.Not cost-effective or efficient.

The correct answer isBbecause the company wants to view bothAmazon EKS clustersandon-premises Kubernetes clustersfrom acentral locationwith theleast operational overhead.Amazon EKS Connectoris designed for this purpose. It allows externally managed Kubernetes clusters, including on-premises clusters, to be registered to AWS so they can be viewed in theAmazon EKS consolealongside native EKS clusters. This creates a centralized management experience without requiring the company to migrate or rebuild the existing on-premises clusters.

EKS Connector is a low-overhead solution because it extends visibility into Kubernetes environments that are not running directly on Amazon EKS. It provides centralized cluster registration and observability at the AWS management layer while preserving the existing cluster deployments. This is especially useful for hybrid Kubernetes environments where organizations want a single control point for inventory and visibility.

Option A is incorrect becauseAmazon CloudWatch Container Insightsis primarily for metrics, logs, and performance monitoring. Although it provides observability, it is not the primary service for centrally registering and viewing clusters themselves in a unified cluster-management context. Option C is incorrect becauseAWS Systems Manageris not the main service for centralized Kubernetes cluster management. Option D is incorrect becauseAmazon EKS Anywhereis used to run Kubernetes on-premises, but it is not the simplest way to centrally view existing clusters with the least operational effort.

AWS guidance for hybrid Kubernetes visibility recommendsAmazon EKS Connectorfor connecting external Kubernetes clusters to AWS. Therefore, it is the most appropriate solution.

Amazon S3 Intelligent-Tiering is designed for unknown or unpredictable access patterns, automatically moving objects to the most cost-effective tier without performance impact.

It is ideal when you do not know object size or access frequency.

S3 Standard (Option B) works but costs more.

S3 One Zone-IA and Glacier Deep Archive (Options D and A) are not appropriate because data is frequently accessed for processing and persists only 24 hours.
