A global manufacturing company plans to migrate the majority of its applications to AWS. However, the company is concerned about applications that need to remain within a specific country or in the company's central on-premises data center because of data regulatory requirements or requirements for latency of single-digit milliseconds. The company also is concerned about the applications that it hosts in some of its factory sites, where limited network infrastructure exists.

The company wants a consistent developer experience so that its developers can build applications once and deploy on premises, in the cloud, or in a hybrid architecture.

The developers must be able to use the same tools, APIs, and services that are familiar to them.

Which solution will provide a consistent hybrid experience to meet these requirements?

A.

Migrate all applications to the closest AWS Region that is compliant. Set up an AWS Direct Connect connection between the central on-premises data center and AWS. Deploy a Direct Connect gateway.

B.

Use AWS Snowball Edge Storage Optimized devices for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Retain the devices on premises. Deploy AWS Wavelength to host the workloads in the factory sites.

C.

Install AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Use AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites.

D.

Migrate the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds to an AWS Local Zone. Deploy AWS Wavelength to host the workloads in the factory sites.

A company has implemented an ordering system using an event-driven architecture. During initial testing, the system stopped processing orders. Further log analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SQS) standard queue was causing an error on the backend and blocking all subsequentorder messages The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages.

Which step should the solutions architect take to meet these requirements?

A.

Increase the backend processing timeout to 30 seconds to match the visibility timeout.

B.

Reduce the visibility timeout of the queue to automatically remove the faulty message.

C.

Configure a new SQS FIFO queue as a dead-letter queue to isolate the faulty messages.

D.

Configure a new SQS standard queue as a dead-letter queue to isolate the faulty messages.

A company runs a simple Linux application on Amazon EKS by using nodes of the M6i (general purpose) instance type. The company has an EC2 Instance Savings Plan for the M6i family that will expire soon.

A solutions architect must minimize the EKS compute costs when the Savings Plan expires.

Which combination of steps will meet this requirement? (Select THREE.)

A.

Rebuild the application container images to support ARM64 architecture.

B.

Rebuild the application container images to support containers.

C.

Migrate the EKS nodes to the most recent generation of Graviton-based instances.

D.

Replace the EKS nodes with the most recent generation of x86_64 instances.

E.

Purchase a new EC2 Instance Savings Plan for the newly selected Graviton instance family.

F.

Purchase a new EC2 Instance Savings Plan for the newly selected x86_64 instance family.
