A company has a website that enables users to upload videos. Company policy states the uploaded videos must be analyzed for restricted content. An uploaded video is placed in Amazon S3, and a message is pushed to an Amazon SOS queue with the video's location. A backend application pulls this location from Amazon SOS and analyzes the video.
The video analysis is compute-intensive and occurs sporadically during the day The website scales with demand. The video analysis application runs on a fixed number of instances. Peak demand occurs during the holidays, so the company must add instances to the application dunng this time. All instances used are currently on-demand Amazon EC2 T2 instances. The company wants to reduce the cost of the current solution.
Which of the following solutions is MOST cost-effective?

1. A. Keep the website on T2 instance
2. B. Determine the minimum number of website instances required during off-peak times and use Spot Instances to cover them while using Reserved Instances to cover peak deman
3. C. Use Amazon EC2 R4 and Amazon EC2 R5 Reserved Instances in an Auto Scaling group for the video analysis application
4. D. Keep the website on T2 instance
5. E. Determine the minimum number of website instances required during off-peak times and use Reserved Instances to cover them while using On-Demand Instances to cover peak deman
6. F. Use Spot Fleet for the video analysis application comprised of Amazon EC2 C4 and Amazon EC2 C5 Spot Instances.
7. G. Migrate the website to AWS Elastic Beanstalk and Amazon EC2 C4 instance
8. H. Determine the minimum number of website instances required during off-peak times and use On-Demand Instances to cover them while using Spot capacity to cover peak demand Use Spot Fleet for the video anarysis application comprised of C4 and Amazon EC2 C5 instances.
9. I. Migrate the website to AWS Elastic Beanstalk and Amazon EC2 R4 instance
10. J. Determine the minimum number of website instances required during off-peak times and use Reserved Instances to cover them while using On-Demand Instances to cover peak demand Use Spot Fleet for the video analysis application comprised of R4 and Amazon EC2 R5 instances

Correct Answer: B

A company is running a workload that consists of thousands of Amazon EC2 instances The workload is running in a VPC that contains several public subnets and private subnets The public subnets have a route for 0 0 0 0/0 to an existing internet gateway. The private subnets have a route for 0 0 0 0/0 to an existing NAT gateway
A solutions architect needs to migrate the entire fleet of EC2 instances to use IPv6 The EC2 instances that are in private subnets must not be accessible from the public internet
What should the solutions architect do to meet these requirements?

1. A. Update the existing VPC and associate a custom IPv6 CIDR block with the VPC and all subnets Update all the VPC route tables and add a route for /0 to the internet gateway
2. B. Update the existing VP
3. C. and associate an Amazon-provided IPv6 CIDR block with the VPC and all subnets Update the VPC route tables for all private subnets, and add a route for /0 to the NAT gateway
4. D. Update the existing VP
5. E. and associate an Amazon-provided IPv6 CIDR block with the VPC and ail subnets Create an egress-only internet gateway Update the VPC route tables for all private subnets, and add a route for /0 to the egress-only internet gateway
6. F. Update the existing VPC and associate a custom IPv6 CIDR block with the VPC and all subnets Create a new NAT gateway, and enable IPv6 support Update the VPC route tables for all private subnets and add a route for 70 to the IPv6-enabled NAT gateway.

A company has an Amazon VPC that is divided into a public subnet and a pnvate subnet. A web application runs in Amazon VPC. and each subnet has its own NACL The public subnet has a CIDR of 10.0.0 0/24 An Application Load Balancer is deployed to the public subnet The private subnet has a CIDR of 10.0.1.0/24. Amazon EC2 instances that run a web server on port 80 are launched into the private subnet
Onty network traffic that is required for the Application Load Balancer to access the web application can be allowed to travel between the public and private subnets
What collection of rules should be written to ensure that the private subnet's NACL meets the requirement? (Select TWO.)

1. A. An inbound rule for port 80 from source 0.0 0.0/0
2. B. An inbound rule for port 80 from source 10.0 0 0/24
3. C. An outbound rule for port 80 to destination 0.0.0.0/0
4. D. An outbound rule for port 80 to destination 10.0.0.0/24
5. E. An outbound rule for ports 1024 through 65535 to destination 10.0.0.0/24

A company is running an application in the AWS Cloud. The company has several third-party services that integrate with the application through a RESTful API. The API is a serverless implementation with an Amazon API Gateway regional API endpoint that integrates with several different AWS Lambda functions.
The application's data is nonrelational and is stored in an Amazon DynamoDB table. The application and the API are running in the eu-west-1 Region. The company needs the API to also be available in the us-east-1 Region. All data must be available in both Regions. A solutions architect already has deployed all the Lambda functions in us-east-1
Which additional steps should the solutions architect take to meet these requirements? (Select TWO.)

1. A. Deploy a second API Gateway regional API endpoint in us-east-1. Create Lambda integration with the functions in us-east-1.
2. B. Enable DynamoDB Streams on the table in eu-west-1. Replicate all changes to a DynamoDB table in us-east-1
3. C. Modify the DynamoDB table to be a global table in eu-west-1 and in us-east-1.
4. D. Change the API Gateway API endpoint in eu-west-1 to an edge-optimized endpoin
5. E. Create Lambda integration with the functions in both Regions.
6. F. Create a DynamoDB read replica in us-east-1.
