A software company is using three AWS accounts for each of its 1 0 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?

1. A. 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
2. B. 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
3. C. Remove two NAT gateways from the standard VPC template Rely on the NAT gateway SLA to cover reliability for the remaining NAT gateway.
4. D. 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

Correct Answer: A

A company has registered 10 new domain names. The company uses the domains for online marketing. The company needs a solution that will redirect online visitors to a specific URL for each domain. All domains and target URLs are defined in a JSON document. All DNS records are managed by Amazon Route 53.
A solutions architect must implement a redirect service that accepts HTTP and HTTPS requests.
Which combination of steps should the solutions architect take to meet these requirements with the LEAST amount of operational effort? (Choose three.)

1. A. Create a dynamic webpage that runs on an Amazon EC2 instanc
2. B. Configure the webpage to use the JSON document in combination with the event message to look up and respond with a redirect URL.
3. C. Create an Application Load Balancer that includes HTTP and HTTPS listeners.
4. D. Create an AWS Lambda function that uses the JSON document in combination with the event message to look up and respond with a redirect URL.
5. E. Use an Amazon API Gateway API with a custom domain to publish an AWS Lambda function.
6. F. Create an Amazon CloudFront distributio
7. G. Deploy a Lambda@Edge function.
8. H. Create an SSL certificate by using AWS Certificate Manager (ACM). Include the domains as Subject Alternative Names.

A company is running a web application with On-Demand Amazon EC2 instances in Auto Scaling groups that scale dynamically based on custom metrics After extensive testing, the company determines that the m5.2xlarge instance size is optimal for the workload Application data is stored in db.r4.4xlarge Amazon RDS instances that are confirmed to be optimal. The traffic to the web application spikes randomly during the day.
What other cost-optimization methods should the company implement to further reduce costs without impacting the reliability of the application?

1. A. Double the instance count in the Auto Scaling groups and reduce the instance size to m5.large
2. B. Reserve capacity for the RDS database and the minimum number of EC2 instances that are constantly running.
3. C. Reduce the RDS instance size to db.r4.xlarge and add five equivalent^ sized read replicas to provide reliability.
4. D. Reserve capacity for all EC2 instances and leverage Spot Instance pricing for the RDS database.

Correct Answer: B
People are being confused by the term 'reserve capacity'. This is not the same as an on-demand capacity reservation. This article by AWS clearly states that by 'reserving capacity' you are reserving the instances and reducing your costs. See https://aws.amazon.com/aws-cost-management/aws-cost-optimization/reserved-instances/

A company has applications in an AWS account that is named Source. The account is in an organization in AWS Organizations. One of the applications uses AWS Lambda functions and stores inventory data in an Amazon Aurora database. The application deploys the Lambda functions by using a deployment package. The company has configured automated backups for Aurora.
The company wants to migrate the Lambda functions and the Aurora database to a new AWS account that is named Target. The application processes critical data, so the company must minimize downtime.
Which solution will meet these requirements?

1. A. Download the Lambda function deployment package from the Source accoun
2. B. Use the deployment package and create new Lambda functions in the Target accoun
3. C. Share the automated Aurora DB cluster snapshot with the Target account.
4. D. Download the Lambda function deployment package from the Source accoun
5. E. Use the deployment package and create new Lambda functions in the Target account Share the Aurora DB cluster with the Target account by using AWS Resource Access Manager {AWS RAM). Grant the Target account permission to clone the Aurora DB cluster.
6. F. Use AWS Resource Access Manager (AWS RAM) to share the Lambda functions and the Aurora DB cluster with the Target accoun
7. G. Grant the Target account permission to clone the Aurora DB cluster.
8. H. Use AWS Resource Access Manager (AWS RAM) to share the Lambda functions with the Target accoun
9. I. Share the automated Aurora DB cluster snapshot with the Target account.

Correct Answer: C

A financial services company in North America plans to release a new online web application to its customers on AWS . The company will launch the application in the us-east-1 Region on Amazon EC2 instances. The application must be highly available and must dynamically scale to meet user traffic. The company also wants to implement a disaster recovery environment for the application in the us-west-1 Region by using active-passive failover.
Which solution will meet these requirements?

1. A. Create a VPC in us-east-1 and a VPC in us-west-1 Configure VPC peering In the us-east-1 VP
2. B. create an Application Load Balancer (ALB) that extends across multiple Availability Zones in both VPCs Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs Place the Auto Scaling group behind the ALB.
3. C. Create a VPC in us-east-1 and a VPC in us-west-1. In the us-east-1 VP
4. D. create an Application Load Balancer (ALB) that extends across multiple Availability Zones in that VP
5. E. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in the us-east-1 VPC Place the Auto Scaling group behind the ALB Set up the same configuration in the us-west-1 VP
6. F. Create an Amazon Route 53 hosted zone Create separate records for each ALB Enable health checks to ensure high availability between Regions.
