The web application will provide access to a repository of text documents totaling about 900 TB in size. The company anticipates that the web application will experience periods of high demand. A solutions architect must ensure that the storage component for the text documents can scale to meet the demand of the application at all times. The company is concerned about the overall cost of the solution.

Which storage solution meets these requirements MOST cost-effectively?

Options:

A.

Amazon Elastic Block Store (Amazon EBS)

B.

Amazon Elastic File System (Amazon EFS)

C.

Amazon Elasticsearch Service (Amazon ES)

Amazon S3

Question 106

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?

Options:

A.

Create a new SSL certificate using AWS Certificate Manager (ACM) install the ACM certificate on each instance

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

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

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

The analytics software, the web server that provides PHP, and the database server are all hosted on the EC2 instance. The application is showing signs of performance degradation during busy times and is presenting 5xx errors. The company needs to make the application scale seamlessly.

Which solution will meet these requirements MOST cost-effectively?

Options:

A.

Migrate the database to an Amazon RDS for MySQL DB instance. Create an AMI of the web application. Use the AMI to launch a second EC2 On-Demand Instance. Use an Application Load Balancer to distribute the load to each EC2 instance.

B.

Use Spot Instances in an Amazon Elastic Kubernetes Service (Amazon EKS) managed node group.

C.

Use On-Demand Instances in an Amazon EC2 Auto Scaling group to run the application containers.

D.

Use On-Demand Instances in an Amazon Elastic Kubernetes Service (Amazon EKS) managed node group.
