A gaming application is deployed on four Amazon EC2 instances in a default VPC. The SysOps administrator has noticed consistently high latency in responses as data is transferred among the four instances. There is no way for the administrator to alter the application code.
The MOST effective way to reduce latency is to relaunch the EC2 instances in:

• A.a placement group.
• B.a single Availability Zone.
• C.a single subnet inside the VPC.
• D.a dedicated VPC.

A SysOps administrator has an AWS CloudFormation template of the company's existing infrastructure in us-west-2. The administrator attempts to use the template to launch a new stack in eu-west-1, but the stack only partially deploys, receives an error message, and then rolls back.
Why would this template fail to deploy? (Select TWO.)

• A.The template did not have the proper level of permissions to deploy the resources.
• B.The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1.
• C.The template requested services that do not exist in eu-west-1.
• D.The template referenced an IAM user that is not available in eu-west-1.
• E.CloudFormation templates can be used only to update existing services.

A company's SysOps administrator has created an Amazon EC2 instance with custom software that will be used as a template for all new EC2 instances across multiple AWS accounts. The Amazon Elastic Block Store (Amazon EBS) volumes that are attached to the EC2 instance are encrypted with AWS managed keys.
The SysOps administrator creates an Amazon Machine Image (AMI) of the custom EC2 instance and plans to share the AMI with the company's other AWS accounts. The company requires that all AMIs are encrypted with AWS Key Management Service (AWS KMS) keys and that only authorized AWS accounts can access the shared AMIs.
Which solution will securely share the AMI with the other AWS accounts?

• A.In the account where the AMI was created, create a customer master key (CMK). Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the AWS accounts that the AMI will be shared with. Create a copy of the AMI, and specify the CMK. Modify the permissions on the copied AMI to specify the AWS account numbers that the AMI will be shared with.
• B.In the account where the AMI was created, create a customer master key (CMK). Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the AWS accounts that the AMI will be shared with. Create a copy of the AMI, and specify the CMK. Modify the permissions on the copied AMI to make it public.
• C.In the account where the AMI was created, modify the key policy of the AWS managed key to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the AWS accounts that the AMI will be shared with. Modify the AMI permissions to specify the AWS account numbers that the AMI will be shared with.
• D.In the account where the AMI was created, create a customer master key (CMK). Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the AWS accounts that the AMI will be shared with. Modify the AMI permissions to specify the AWS account numbers that the AMI will be shared with.

A company has an existing web application that runs on two Amazon EC2 instances behind an Application Load Balancer (ALB) across two Availability Zones The application uses an Amazon RDS Multi-AZ DB Instance Amazon Route 53 record sets route requests tor dynamic content to the load balancer and requests for static content to an Amazon S3 bucket Site visitors are reporting extremely long loading times.
Which actions should be taken to improve the performance of the website? (Select TWO )

• A.Move the static content from Amazon S3 to the web servers
• B.Add Amazon CloudFront caching for static content
• C.Change the load balancer listener from HTTPS to TCP
• D.Implement Amazon EC2 Auto Scaling for the web servers
• E.Enable Amazon Route 53 latency-based routing
