A company wants to migrate an Oracle database to AWS. The database consists of a single table that contains millions of geographic information systems (GIS) images that are high resolution and are identified by a geographic code.
When a natural disaster occurs tens of thousands of images get updated every few minutes. Each geographic code has a single image or row that is associated with it. The company wants a solution that is highly available and scalable during such events
Which solution meets these requirements MOST cost-effectively?

1. A. Store the images and geographic codes in a database table Use Oracle running on an Amazon RDS Multi-AZ DB instance
2. B. Store the images in Amazon S3 buckets Use Amazon DynamoDB with the geographic code as the key and the image S3 URL as the value
3. C. Store the images and geographic codes in an Amazon DynamoDB table Configure DynamoDB Accelerator (DAX) during times of high load
4. D. Store the images in Amazon S3 buckets Store geographic codes and image S3 URLs in a database table Use Oracle running on an Amazon RDS Multi-AZ DB instance.

Correct Answer: A

A solutions architect must migrate a Windows Internet Information Services (IIS) web application to AWS The application currently relies on a file share hosted in the user's on-premises network-attached storage (NAS) The solutions architect has proposed migrating the MS web servers to Amazon EC2 instances in multiple Availability Zones that are connected to the storage solution, and configuring an Elastic Load Balancer attached to the instances
Which replacement to the on-premises file share is MOST resilient and durable?

1. A. Migrate the file share to Amazon RDS
2. B. Migrate the file share to AWS Storage Gateway
3. C. Migrate the file share to Amazon FSx for Windows File Server
4. D. Migrate the file share to Amazon Elastic File System (Amazon EFS)

Correct Answer: C

A company wants to migrate its on-premises application to AWS. The application produces output files that vary in size from tens of gigabytes to hundreds of terabytes The application data must be stored in a standard file system structure The company wants a solution that scales automatically, is highly available, and requires minimum operational overhead.
Which solution will meet these requirements?

1. A. Migrate the application to run as containers on Amazon Elastic Container Service (Amazon ECS) Use Amazon S3 for storage
2. B. Migrate the application to run as containers on Amazon Elastic Kubernetes Service (Amazon EKS) Use Amazon Elastic Block Store (Amazon EBS) for storage
3. C. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling grou
4. D. Use Amazon Elastic File System (Amazon EFS) for storage.
5. E. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling grou
6. F. Use Amazon Elastic Block Store (Amazon EBS) for storage.

Correct Answer: C
EFS is a standard file system, it scales automatically and is highly available.

A company wants to migrate a Windows-based application from on premises to the AWS Cloud. The application has three tiers, a business tier, and a database tier with Microsoft SQL Server. The company wants to use specific features of SQL Server such as native backups and Data Quality Services. The company also needs to share files for process between the tiers.
How should a solution architect design the architecture to meet these requirements?

1. A. Host all three on Amazon instance
2. B. Use Mmazon FSx File Gateway for file sharing between tiers.
3. C. Host all three on Amazon EC2 instance
4. D. Use Amazon FSx for Windows file sharing between the tiers.
5. E. Host the application tier and the business tier on Amazon EC2 instance
6. F. Host the database tier on Amazon RD
7. G. Use Amazon Elastic File system (Amazon EFS) for file sharing between the tiers.
8. H. Host the application tier and the business tier on Amazon EC2 instance
9. I. Host the database tier on Amazon RD
10. J. Use a Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volume for file sharing between the tiers.

Correct Answer: B

A company has a dynamic web application hosted on two Amazon EC2 instances. The company has its own SSL certificate, which is on each instance to perform SSL termination.
There has been an increase in traffic recently, and the operations team determined that SSL encryption and decryption is causing the compute capacity of the web servers to reach their maximum limit.
What should a solutions architect do to increase the application's performance?

1. A. Create a new SSL certificate using AWS Certificate Manager (ACM) install the ACM certificate on each instance
2. B. Create an Amazon S3 bucket Migrate the SSL certificate to the S3 bucket Configure the EC2 instances to reference the bucket for SSL termination
3. C. Create another EC2 instance as a proxy server Migrate the SSL certificate to the new instance and configure it to direct connections to the existing EC2 instances
4. D. Import the SSL certificate into AWS Certificate Manager (ACM) Create an Application Load Balancer with an HTTPS listener that uses the SSL certificate from ACM

Correct Answer: D
https://aws.amazon.com/certificate-manager/:
"With AWS Certificate Manager, you can quickly request a certificate, deploy it on ACM-integrated AWS resources, such as Elastic Load Balancers, Amazon CloudFront distributions, and APIs on API Gateway, and let AWS Certificate Manager handle certificate renewals. It also enables you to create private certificates for
your internal resources and manage the certificate lifecycle centrally."
