A company wants to control its cost of Amazon Athena usage The company has allocated a specific monthly budget for Athena usage A solutions architect must design a solution that will prevent the company from exceeding the budgeted amount Which solution will moot these requirements?

• A.Use Athena workgroups to set a limit on the amount of data that can be scanned. Set a limit that is appropriate for the monthly budget and the current pricing for Athena.
• B.Use AWS Trusted Advisor to track the cost of Athena usage. Configure an Amazon EventBridge (Amazon CloudWatch Events) rule to deactivate Athena until the end of the month whenever the cost reaches the budgeted amount for the month
• C.Use Cost Explorer to create an alert for when the cost of Athena usage reaches the budgeted amount for the month. Configure Cost Explorer to publish notifications to an Amazon Simple Notification Service (Amazon SNS) topic.
• D.Use AWS Budgets. Create an alarm (or when the cost of Athena usage reaches the budgeted amount for the month. Configure AWS Budgets actions to deactivate Athena until the end of the month.

An organization has two Amazon EC2 instances:
* The first is running an ordering application and an inventory application.
* The second is running a queuing system.
During certain times of the year, several thousand orders are placed per second. Some orders were lost when the queuing system was down. Also, the organization's inventory application has the incorrect quantity of products because some orders were processed twice.
What should be done to ensure that the applications can handle the increasing number of orders?

• A.Put the ordering and inventory applications into their own AWS Lambda functions. Have the ordering application write the messages into an Amazon SQS FIFO queue.
• B.Put the ordering and inventory applications into their own Amazon ECS containers and create an Auto Scaling group for each application. Then, deploy the message queuing server in multiple Availability Zones.
• C.Put the ordering and inventory applications into their own Amazon EC2 instances, and create an Auto Scaling group for each application. Use Amazon SQS standard queues for the incoming orders, and implement idempotency in the inventory application.
• D.Put the ordering and inventory applications into their own Amazon EC2 instances. Write the incoming orders to an Amazon Kinesis data stream Configure AWS Lambda to poll the stream and update the inventory application.

A company's CI SO has asked a solutions architect to re-engineer the company's current CI/CD practices to make sure patch deployments to its application can happen as quickly as possible with minimal downtime if vulnerabilities are discovered The company must also be able to quickly roll back a change in case of errors.
The web application is deployed in a fleet of Amazon EC2 instances behind an Application Load Balancer The company is currently using GitHub to host the application source code. and has configured an AWS CodeBuild project to build the application The company also intends to use AWS CodePipeline to trigger builds from GitHub commits using the existing CodeBuild project.
What CI/CD configuration meets all of the requirements?

• A.Configure the CodePipeline with a deploy stage using AWS OpsWorks and m-place deployments Monitor the newly deployed code and. if there are any issues, push another code update
• B.Configure CodePipeline with a deploy stage using AWS CloudFormation to create a pipeline for test and production stacks Monitor the newly deployed code, and, if there are any issues, push another code update
• C.Configure CodePipeline with a deploy stage using AWS CodeDeploy configured for in-place deployment Monitor the newly deployed code, and, if there are any issues, push another code update
• D.Configure CodePipeline with a deploy stage using AWS CodeDeploy configured for blue/green deployments Monitor the newly deployed code and if there are any issues, trigger a manual rollback using CodeDeploy

A solutions architect has implemented a SAML 2.0 federated identity solution with their company's on-premises identity provider (IdP) to authenticate users' access to the AWS environment. When the solutions architect tests authentication through the federated identity web portal access to the AWS environment is granted However, when test users attempt to authenticate through the federated identity web portal, they are not able to access the AWS environment.
Which items should the solutions architect check to ensure identity federation is property configured? (Select THREE j

• A.The on-premises IdP's DNS hostname is reachable from the AWS environment VPCs.
• B.The web portal calls the AWS STS AssumeRoleWithSAML API with the ARN of the SAML provider the ARN of the 1AM role, and the SAML assertion from IdP
• C.The company's IdP defines SAML assertions that property map users or groups m the company to 1AM roles with appropriate permissions
• D.Test users are not in the AWSFederatedUsers group in the company's IdP
• E.The 1AM roles created for the federated users' or federated groups' trust policy have set the SAML provider as the principle.
• F.The 1AM user's permissions pokey has allowed the use of SAML federation for that user

A company runs an application in the cloud that consists of a database and a website Users can post data to the website, have the data processed, and have the data sent back to them in an email. Data is stored in a MySQL database running on an Amazon EC2 instance The database is running in a VPC with two private subnets The website is running on Apache Tomcat in a single EC2 instance in a different VPC with one public subnet There is a single VPC peering connection between the database and website VPC.
The website has suffered several outages during the last month due to high traffic
Which actions should a solutions architect take to increase the reliability of the application? (Select THREE )

• A.Create an additional public subnet in a different Availability Zone in the website VPC
• B.Provision two NAT gateways in the database VPC
• C.Move the Tomcat server to the database VPC
• D.Migrate the MySQL database to Amazon Aurora with one Aurora Replica
• E.Provision an additional VPC peering connection
• F.Place the Tomcat server in an Auto Scaling group with multiple EC2 instances behind an Application Load Balancer
