A company will host a static website within an Amazon S3 bucket The website will serve millions of users globally, and the company wants to minimize data transfer costs.
What should the Solutions Architect do to ensure costs are kept to a minimum?

• A.Use cross-region replication to copy the website to an additional S3 bucket in a different region
• B.Create an Amazon CloudFront distribution, with the S3 bucket as the origin server.
• C.Implement an AWS Auto Scaling group for the website to ensure it grows with use.
• D.Move the website to large compute-optimized Amazon EC2 instances.

A company operates an ecommerce website on Amazon EC2 instances behind an Application Load Balancer (ALB) in an Auto Scaling group The site is experiencing performance issues related to a high request rate from illegitimate external systems with changing IP addresses The security team is worried about potential DDoS attacks against the website The company must block the illegitimate incoming requests in a way that has a minimal impact on legitimate users.
What should a solutions architect recommend1?

• A.Deploy AWS WAR associate it with the ALB and configure a rate-limiting rule.
• B.Deploy Amazon GuardDuty and enable rate-limiting protection when configunng GuardDuty.
• C.Deploy Amazon Inspector and associate it with the ALB.
• D.Deploy rules to the network ACLs associated with the ALB to block the incoming traffic

A company's application Is having performance issues The application staleful and needs to complete m-memory tasks on Amazon EC2 instances. The company used AWS CloudFormation to deploy infrastructure and used the M5 EC2 Instance family As traffic increased, the application performance degraded Users are reporting delays when the users attempt to access the application.
Which solution will resolve these issues in the MOST operationally efficient way?

• A.Replace the EC2 Instances with T3 EC2 instances that run in an Auto Scaling group. Made the changes by using the AWS Management Console.
• B.Modify the CloudFormation templates to run the EC2 instances in an Auto Scaling group. Increase the desired capacity and the maximum capacity of the Auto Scaling group manually when an increase is necessary
• C.Modify the CloudFormation templates. Replace the EC2 instances with R5 EC2 instances. Use Amazon CloudWatch built-in EC2 memory metrics to track the application performance for future capacity planning.
• D.Modify the CloudFormation templates. Replace the EC2 instances with R5 EC2 instances. Deploy the Amazon CloudWatch agent on the EC2 instances to generate custom application latency metrics for future capacity planning.

You've created your first load balancer and have registered your EC2 instances with the load balancer.
Elastic Load Balancing routinely performs health checks on all the registered EC2 instances and automatically distributes all incoming requests to the DNS name of your load balancer across your registered, healthy EC2 instances. By default, the load balancer uses the ___ protocol for checking the health of your instances.

• A.HTTPS
• B.HTTP
• C.ICMP
• D.IPv6

A Solutions Architect is designing a high-performance computing job that runs on Amazon EC2 instances in private subnets. To allow the application to download patches, the infrastructure must be altered to allow the instances to access external endpoints. Any changes to the infrastructure must involve minimal ongoing systems management effort.
What will allow the EC2 instances to access the endpoint while meeting these requirements?

• A.NAT gateway
• B.Elastic IP address
• C.AWS Direct Connect
• D.Virtual private gateway
