A company is running a .NET three-tier web application on AWS. The team currently uses XL storage optimized instances to store serve the website's image and video files on local instance storage. The company has encountered issues with data loss from replication and instance failures. The Solutions Architect has been asked to redesign this application to improve its reliability while keeping costs low.
Which solution will meet these requirements?

• A.Implement Auto Scaling with general purpose instance types and an Elastic Load Balancer. Enable an Amazon CloudFront distribution to Amazon S3 and move images and video files to Amazon S3.
  Reserve general purpose instances to meet base performance requirements. Use Cost Explorer and AWS Trusted Advisor checks to continue monitoring the environment for future savings.
• B.Use AWS Elastic Beanstalk to deploy the .NET application. Move all images and video files to Amazon EFS. Create an Amazon CloudFront distribution that points to the EFS share. Reserve the m4.4xl instances needed to meet base performance requirements.
• C.Set up a new Amazon EFS share, move all image and video files to this share, and then attach this new drive as a mount point to all existing servers. Create an Elastic Load Balancer with Auto Scaling general purpose instances. Enable Amazon CloudFront to the Elastic Load Balancer. Enable Cost Explorer and use AWS Trusted advisor checks to continue monitoring the environment for future savings.
• D.Move the entire website to Amazon S3 using the S3 website hosting feature. Remove all the web servers and have Amazon S3 communicate directly with the application servers in Amazon VPC.

A data analytics company has an Amazon Redshift cluster that consists of several reserved nodes. The duster is experiencing unexpected bursts of usage because a team of employees is compiling a deep audit analysis report The queries to generate the report are complex read queries and are CPU intensive.
Business requirements dictate that the cluster must be able to service read and write queries at at) times A solutions architect must devise a solution that accommodates the bursts of usage Which solution meets these requirements MOST cost-effectively?

• A.Turn on the Concurrency Scaling feature for the Amazon Redshift duster
• B.Deploy an AWS Lambda function to add capacity to the Amazon Redshift cluster by using a classic resize operation when the duster's CPU metrics in Amazon CloudWatch reach 80%.
• C.Provision an Amazon EMR duster Offload the complex data processing tasks
• D.Deploy an AWS Lambda function to add capacity to the Amazon Redshift duster by using an elastic resize operation when the duster's CPU metrics in Amazon CloudWatch leach 80%.

A company is running multiple workloads in the AWS Cloud The company has separate units for software development The company uses AWS Organizations and federation with SAML to give permissions to developers to manage resources in their AWS accounts The development units each deploy their production workloads into a common production account Recently, an incident occurred in the production account in which members of a development unit terminated an EC2 instance that belonged to a different development unit. A solutions architect must create a solution that prevents a similar incident from happening in the future. The solution also must a low developers the possibilityy to manage the instances used for their workloads.
Which strategy will meet these requirements?

• A.Pass an attribute for DevelopmentUnit as an AWS Security Token Service (AWS STS) session tag during SAML federation Update the 1AM policy for the developers' assumed 1AM role with a deny action and a StringNotEquals condition for the DevelopmentUnit resource tag and aws PrincipalTag/DevelopmentUnit
• B.Create separate OUs in AWS Organizations for each development unit Assign the created OUs to the company AWS accounts Create separate SCPs with a deny action and a StringNotEquals condition for the DevelopmentUnit resource tag that matches the development unit name Assign the SCP to the corresponding OU
• C.Create separate 1AM policies for each development unit For every 1AM policy add an allow action and a StringEquals condition for the DevelopmentUnit resource tag and the development unit name During SAML federation use AWS Security Token Service (AWS STS) to assign the 1AM policy and match the development unit name to the assumed IAM role
• D.Pass an attribute for DevelopmentUnit as an AWS Security Token Service (AWS STS) session tag during SAML federation Create an SCP with an allow action and a StrmgEquals condition for the DevelopmentUnit resource tag and aws Principal Tag 'DevelopmentUnit Assign the SCP to the root OU.

A company runs an loT platform on AWS loT sensors in various locations send data to the company's Node js API servers on Amazon EC2 instances running behind an Application Load Balancer The data is stored in an Amazon RDS MySQL DB instance that uses a 4 TB General Purpose SSD volume The number of sensors the company has deployed in the field has increased over time and is expected to grow significantly The API servers are consistently overloaded and RDS metrics show high write latency Which of the following steps together will resolve the issues permanently and enable growth as new sensors are provisioned, while keeping this platform cost-efficient? {Select TWO.)

• A.Re-architect the database tier to use Amazon Aurora instead of an RDS MySQL DB instance and add read replicas
• B.Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance
• C.Resize the MySQL General Purpose SSD storage to 6 TB to improve the volume's IOPS
• D.Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data
• E.Use AWS X-Ray to analyze and debug application issues and add more API servers to match the load

A company is migrating an application to AWS. It wants to use fully managed services as much as possible during the migration. The company needs to store large, important documents within the application with the following requirements:
* The data must be highly durable and available.
* The data must always be encrypted at rest and in transit.
* The encryption key must be managed by the company and rotated periodically.
Which of the following solutions should the Solutions Architect recommend?

• A.Deploy the storage gateway to AWS in file gateway mode. Use Amazon EBS volume encryption using an AWS KMS key to encrypt the storage gateway volumes.
• B.Use Amazon S3 with a bucket policy to enforce HTTPS for connections to the bucket and to enforce server-side encryption and AWS KMS for object encryption.
• C.Use Amazon DynamoDB with SSL to connect to DynamoDB. Use an AWS KMS key to encrypt DynamoDB objects at rest.
• D.Deploy instances with Amazon EBS volumes attached to store this data. Use EBS volume encryption using an AWS KMS key to encrypt the data.
