A SysOps Administrator needs to report on Amazon EC2 instance cost by both project and environment (production, staging, development).
Which action would impact the operations team the LEAST?

• A.Use AWS Organizations to create a new organization for each project, then for each environment use a separate linked AWS account
• B.Implement cost allocation tagging in the Billing and Cost Management console to implement tags to identify resources by project and environment
• C.For each project and environment, create a new AWS account and link them to the master payer for unified management and billing
• D.Add the project and environment information to the instance metadata so that the values can be queried and rolled up into reports

A Big Data consulting company wants to separate its customers' workloads for billing and security reasons. The company would like to maintain billing and security controls on these workloads.
According to best practices, how can the workloads be separated if no shared resources are needed?

• A.Create customer accounts within AWS Organizations specifying consolidated billing features.
• B.Create a separate VPC for each customer. Use security groups to isolate traffic.
• C.Dedicate an AWS Region to each customer. Ensure that each entry in Amazon Route 53 is unique.
• D.Require each customer to create their own account. Contact AWS Support to receive a consolidated bill.

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. Modify the AMI permissions 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 specify the AWS account numbers that the AMI will be shared with.
• C.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.
• D.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.

• A.Activate the createdBy tag in the account.
• B.Analyze the usage with Amazon CloudWatch dashboards.
• C.Configure AWS Trusted Advisor to track resource usage.
• D.Create a billing alarm in AWS Budgets.
• E.Analyze the usage with Cost Explorer.

A company analyzes sales data for its customers. Customers upload files to one of the company's Amazon S3 buckets, and a message is posted to an Amazon Simple Queue Service (Amazon SQS) queue that contains the object Amazon Resource Name (ARN). An application that runs on an Amazon EC2 instance polls the queue and processes the messages. The processing time depends on the size of the file.
Customers are reporting delays in the processing of their files. A SysOps administrator decides to configure Amazon EC2 Auto Scaling as the first step. The SysOps administrator creates an Amazon Machine Image (AMI) that is based on the existing EC2 instance. The SysOps administrator also creates a launch template that references the AMI.
How should the SysOps administrator configure the Auto Scaling policy to improve the response time?

• A.Add several different instance sizes in the launch template.
  Create an Auto Scaling policy based on the ApproximateNumberOfMessagesVisible metric to select the size of the instance based on the number of messages in the queue.
• B.Create an Auto Scaling policy based on the ApproximateNumberOfMessagesDelayed metric to scale the number of instances based on the number of messages in the queue that have been delayed.
• C.Create a custom metric based on the ASGAverageCPUUtilization metric and the GroupPendingInstances metric from the Auto Scaling group.
  Modify the application to calculate the metric and post the metric to Amazon CloudWatch once each minute.
  Create an Auto Scaling policy based on this metric to scale the number of instances.
• D.Create a custom metric based on the ApproximateNumberOfMessagesVisible metric and the number of instances in the InService state in the Auto Scaling group.
  Modify the application to calculate the metric and post the metric to Amazon CloudWatch once each minute.Create an Auto Scaling policy based on this metric to scale the number of instances.
