A company is migrating from an on-premises infrastructure to the AWS Cloud One of the company's applications stores files on a Windows file server farm that uses Distributed File System Replication (DFSR) to keep data in sync A solutions architect needs to replace the file server farm Which service should the solutions architect use?

A. Amazon EFS

B. Amazon FSx

C. Amazon S3

D. AWS Storage Gateway

A solution architect is designing a solution that involves orchestrating a series of Amazon Elastic Container Service (Amazon ECS) task types running on Amazon EC2 instances that are part of an ECS cluster. The output and state data for all

tasks needs to be stored. The amount of data output by each task is approximately 10 MB, and there could be hundreds of tasks running at a time. The system should be optimized for high frequency reading and writing. As old outputs are

archived and deleted the storage size is not expected to exceed 1 TB.

Which storage solution should the solution architect recommend?

A. An Amazon DynamoDB table accessible by all ECS cluster instances.

B. An Amazon Elastic File System (Amazon EFS) with Provisioned Throughput mode.

C. An Amazon Elastic File System (Amazon EFS) file system with Bursting Throughput mode.

D. An Amazon Elastic Block Store (Amazon EBS) volume mounted to the ECS cluster instances.

A company is creating a web application that will store a large number of images in Amazon S3 The images will be accessed by users over variable periods of time. The company wants to:

1.

Retain all the images

2.

Incur no cost for retrieval.

3.

Have minimal management overhead.

4.

Have the images available with no impact on retrieval time.

Which solution meets these requirements?

A. Implement S3 Intelligent-Tiering

B. Implement S3 storage class analysis

C. Implement an S3 Lifecycle policy to move data to S3 Standard-Infrequent Access (S3 Standard-IA).

D. Implement an S3 Lifecycle policy to move data to S3 One Zone-Infrequent Access (S3 One Zone-IA).

A company recently started using Amazon Aurora as the data store for its global ecommerce application. When large reports are run, developers report that the ecommerce application is performing poorly. After reviewing metrics in Amazon

CloudWatch, a solutions architect finds that the ReadlOPS and CPU Utilization metrics are spiking when monthly reports run.

What is the MOST cost-effective solution?

A. Migrate the monthly reporting to Amazon Redshift.

B. Migrate the monthly reporting to an Aurora Replica.

C. Migrate the Aurora database to a larger instance class.

D. Increase the Provisioned IOPS on the Aurora instance.

A company has created an isolated backup of its environment in another Region. The application is running in warm standby mode and is fronted by an Application Load Balancer (ALB). The current failover process is manual and requires updating a DNS alias record to point to the secondary ALB in another Region.

What should a solutions architect do to automate the failover process?

A. Enable an ALB health check.

B. Enable an Amazon Route 53 health check.

C. Create a CNAME record on Amazon Route 53 pointing to the ALB endpoint.

D. Create conditional forwarding rules on Amazon Route 53 pointing to an internal BIND DNS server.
