When AWS workloads must resolve DNS names from on-premises systems over a hybrid network (like VPN or Direct Connect), the best solution is to use Amazon Route 53 Resolver outbound endpoints.

The outbound endpoint enables DNS queries to be forwarded from your VPC to on-premises DNS servers.

You must also configure a Route 53 Resolver forwarding rule to define which domain names (e.g., corp.internal) should be forwarded to the specific on-premises DNS IPs.

This setup allows private DNS resolution from AWS to on-premises systems and is fully managed, eliminating the need to run and maintain EC2-based DNS proxies (as in option A).

Options C and D are incorrect:

C is not DNS-specific and doesn’t solve name resolution.

D misuses a public hosted zone for a private DNS domain.

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 Elastic File System (EFS) is a managed file storage service that can be mounted across multiple EC2 instances. It provides a scalable and high-performing solution to share data among instances within a VPC.

High Performance: EFS provides scalable performance for workloads that require high throughput and IOPS. It is particularly well-suited for applications that need to share data across multiple instances.

Ease of Use: EFS can be easily mounted on multiple instances across different Availability Zones, providing a shared file system accessible to all the instances within the VPC.

Security: EFS can be configured to ensure that data remains within the VPC, and it supports encryption at rest and in transit.

Why Not Other Options?:

Option A (Amazon S3 bucket with APIs): While S3 is excellent for object storage, it is not a file system and does not provide the low-latency access required for shared data between instances.

Option B (S3 bucket as a mounted volume): S3 is not designed to be mounted as a file system, and this approach would introduce unnecessary complexity and latency.

Option C (EBS volume shared across instances): EBS volumes cannot be attached to multiple instances simultaneously. It is not designed to be shared across instances like EFS.
