Question 624

A Development team is deploying new APIs as serverless applications within a company. The team is currently using the AWS Management Console to provision Amazon API Gateway, AWS Lambda, and Amazon DynamoDB resources. A Solutions Architect has been tasked with automating the future deployments of these serverless APIs.

How can this be accomplished?

Use AWS CloudFormation with a Lambda-backed custom resource to provision API Gateway. Use the AWS::DynamoDB::Table and AWS::Lambda::Function resources to create the Amazon DynamoDB table and Lambda functions. Write a script to automate the deployment of the CloudFormation template.

Use the AWS Serverless Application Model to define the resources. Upload a YAML template and application files to the code repository. Use AWS CodePipeline to connect to the code repository and to create an action to build using AWS CodeBuild. Use the AWS CloudFormation deployment provider in CodePipeline to deploy the solution.

Use AWS CloudFormation to define the serverless application. Implement versioning on the Lambda functions and create aliases to point to the versions. When deploying, configure weights to implement shifting traffic to the newest version, and gradually update the weights as traffic moves over.

Commit the application code to the AWS CodeCommit code repository. Use AWS CodePipeline and connect to the CodeCommit code repository. Use AWS CodeBuild to build and deploy the Lambda functions using AWS CodeDeploy. Specify the deployment preference type in CodeDeploy to gradually shift traffic over to the new version.

Question 625

A company is running a batch analysis every hour on their main transactional DB, running on an RDS MySQL instance, to populate their central Data Warehouse running on Redshift. During the execution of the batch, their transactional applications are very slow. When the batch completes they need to update the top management dashboard with the new data. The dashboard is produced by another system running on-premises that is currently started when a manually-sent email notifies that an update is required. The on-premises system cannot be modified because is managed by another team. How would you optimize this scenario to solve performance issues and automate the process as much as possible?

Replace RDS with Redshift for the batch analysis and SNS to notify the on-premises system to update the dashboard

Replace RDS with Redshift for the oaten analysis and SQS to send a message to the on-premises system to update the dashboard

Create an RDS Read Replica for the batch analysis and SNS to notify me on-premises system to update the dashboard

Create an RDS Read Replica for the batch analysis and SQS to send a message to the on-premises system to update the dashboard.

Question 626

A large real-estate brokerage is exploring the option of adding a cost-effective location based alert to their existing mobile application. The application backend infrastructure currently runs on AWS. Users who opt in to this service will receive alerts on their mobile device regarding real-estate otters in proximity to their location. For the alerts to be relevant delivery time needs to be in the low minute count the existing mobile app has 5 million users across the US. Which one of the following architectural suggestions would you make to the customer?

The mobile application will submit its location to a web service endpoint utilizing Elastic Load Balancing and EC2 instances; DynamoDB will be used to store and retrieve relevant offers EC2 instances will communicate with mobile earners/device providers to push alerts back to mobile application.

Use AWS DirectConnect or VPN to establish connectivity with mobile carriers EC2 instances will receive the mobile applications location through carrier connection: RDS will be used to store and relevant offers. EC2 instances will communicate with mobile carriers to push alerts back to the mobile application.

The mobile application will send device location using SQS. EC2 instances will retrieve the relevant others from DynamoDB. AWS Mobile Push will be used to send offers to the mobile application.

The mobile application will send device location using AWS Mobile Push EC2 instances will retrieve the relevant offers from DynamoDB. EC2 instances will communicate with mobile carriers/device providers to push alerts back to the mobile application.

Question 627

A software company is using three AWS accounts for each of its 10 development teams. The company has developed an AWS CloudFormation standard VPC template that includes three NAT gateways. The template is added to each account for each team. The company is concerned that network costs will increase each time a new development team is added. A solutions architect must maintain the reliability of the company’s solutions and minimize operational complexity.

What should the solutions architect do to reduce the network costs while meeting these requirements?

Create a single VPC with three NAT gateways in a shared services account. Configure each account VPC with a default route through a transit gateway to the NAT gateway in the shared services account VPC. Remove all NAT gateways from the standard VPC template.

Create a single VPC with three NAT gateways in a shared services account. Configure each account VPC with a default route through a VPC peering connection to the NAT gateway in the shared services account VPC. Remove all NAT gateways from the standard VPC template.

Remove two NAT gateways from the standard VPC template. Rely on the NAT gateway SLA to cover reliability for the remaining NAT gateway.

Create a single VPC with three NAT gateways in a shared services account. Configure a Site-to-Site VPN connection from each account to the shared services account. Remove all NAT gateways from the standard VPC template.

Question 629

A company’s solutions architect is analyzing costs of a multi-application environment. The environment is deployed across multiple Availability Zones in a single AWS Region. After a recent acquisition, the company manages two organizations in AWS Organizations. The company has created multiple service provider applications as AWS PrivateLink-powered VPC endpoint services in one organization. The company has created multiple service consumer applications in the other organization.

Data transfer charges are much higher than the company expected, and the solutions architect needs to reduce the costs. The solutions architect must recommend guidelines for developers to follow when they deploy services. These guidelines must minimize data transfer charges for the whole environment. Which guidelines meet these requirements? (Choose two.)

Use AWS Resource Access Manager to share the subnets that host the service provider applications with other accounts in the organization.

Place the service provider applications and the service consumer applications in AWS accounts in the same organization.

Turn off cross-zone load balancing for the Network Load Balancer in all service provider application deployments.

Ensure that service consumer compute resources use the Availability Zone-specific endpoint service by using the endpoint’s local DNS name.

Create a Savings Plan that provides adequate coverage for the organization’s planned inter-Availability Zone data transfer usage.

Question 630

A company is running an Apache Hadoop cluster on Amazon EC2 instances. The Hadoop cluster stores approximately 100 TB of data for weekly operational reports and allows occasional access for data scientists to retrieve data. The company needs to reduce the cost and operational complexity for storing and serving this data.

Which solution meets these requirements in the MOST cost-effective manner?

Move the Hadoop cluster from EC2 instances to Amazon EMR. Allow data access patterns to remain the same.

Write a script that resizes the EC2 instances to a smaller instance type during downtime and resizes the instances to a larger instance type before the reports are created.

Move the data to Amazon S3 and use Amazon Athena to query the data for reports. Allow the data scientists to access the data directly in Amazon S3.

Migrate the data to Amazon DynamoDB and modify the reports to fetch data from DynamoDB. Allow the data scientists to access the data directly in DynamoDB.
