A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances. The fleet consists of a primary node and eight worker nodes. The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes and sending an aggregate response back to a client. Worker nodes communicate with each other to replicate data partitions.
The company requires the lowest possible networking latency to achieve maximum performance. Which solution will meet these requirements?

1. A. Launch memory optimized EC2 instances in a partition placement group
2. B. Launch compute optimized EC2 instances in a partition placement group
3. C. Launch memory optimized EC2 instances in a cluster placement group
4. D. Launch compute optimized EC2 instances in a spread placement group.

Correct Answer: B

A company that has multiple AWS accounts is using AWS Organizations. The company’s AWS accounts host VPCs, Amazon EC2 instances, and containers.
The company’s compliance team has deployed a security tool in each VPC where the company has deployments. The security tools run on EC2 instances and send information to the AWS account that is dedicated for the compliance team. The company has tagged all the compliance-related resources with a key of “costCenter” and a value or “compliance”.
The company wants to identify the cost of the security tools that are running on the EC2 instances so that the company can charge the compliance team’s AWS account. The cost calculation must be as accurate as possible.
What should a solutions architect do to meet these requirements?

1. A. In the management account of the organization, activate the costCenter user-defined ta
2. B. Configure monthly AWS Cost and Usage Reports to save to an Amazon S3 bucket in the management accoun
3. C. Use the tag breakdown in the report to obtain the total cost for the costCenter tagged resources.
4. D. In the member accounts of the organization, activate the costCenter user-defined ta
5. E. Configure monthly AWS Cost and Usage Reports to save to an Amazon S3 bucket in the management accoun
6. F. Schedule a monthly AWS Lambda function to retrieve the reports and calculate the total cost for the costCenter tagged resources.
7. G. In the member accounts of the organization activate the costCenter user-defined ta
8. H. From the management account, schedule a monthly AWS Cost and Usage Repor
9. I. Use the tag breakdown in the report to calculate the total cost for the costCenter tagged resources.
10. J. Create a custom report in the organization view in AWS Trusted Adviso
11. K. Configure the report to generate a monthly billing summary for the costCenter tagged resources in the compliance team’s AWS account.

Correct Answer: C

Which combination of steps should a solutions architect recommend to restrict direct content access to CloudFront? (Select THREE)

1. A. Create a web ACL in AWS WAF with a rule to validate the presence of a custom header and associate the web ACL with the ALB
2. B. Create a web ACL in AWS WAF with a rule to validate the presence of a custom header and associate the web ACL with the CloudFront distribution
3. C. Configure CloudFront to add a custom header to origin requests
4. D. Configure the ALB to add a custom header to HTTP requests
5. E. Update the S3 bucket ACL to allow access from the CloudFront distribution only
6. F. Create a CloudFront Origin Access Identity (OAI) and add it to the CloudFront distribution Update the S3 bucket policy to allow access to the OAI only

Correct Answer: ACF

A company has developed a single-page web application in JavaScript. The source code is stored in a single Amazon S3 bucket in the us-east-1 Region. The company serves the web application to a global user base through Amazon CloudFront.
The company wants to experiment with two versions of the website without informing application users. Each version of the website will reside in its own S3 bucket. The company wants to determine which version is most successful in marketing a new product.
The solution must send application users that are based in Europe to the new website design. The solution must send application users that are based in the United States to the current website design. However, some exceptions exist. The company needs to be able to redirect specific users to the new website design, regardless of the users' location.
Which solution meets these requirements?

1. A. Configure two CloudFront distribution
2. B. Configure a geolocation routing policy in Amazon Route 53 to route traffic to the appropriate CloudFront endpoint based on the location of clients.
3. C. Configure a single CloudFront distributio
4. D. Create a behavior with different paths for each version ofthe sit
5. E. Configure Lambda@Edge on the default path to generate redirects and send the client to the correct version of the website.
6. F. Configure a single CloudFront distributio
7. G. Configure an alternate domain name on the distribution.Configure two behaviors to route users to the different S3 origins based on the domain name that the client uses in the HTTP request.
8. H. Configure a single CloudFront distribution with Lambda@Edg
9. I. Use Lambda@Edge to send user requests to different origins based on request attributes.

Correct Answer: A

A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs The company needs to increase visibility into details of AWS Billing and Cost Management There are various accounts associated with AWS Organizations, including many development and production accounts. There is no consistent tagging strategy across the organization, but there are guidelines in place that require all infrastructure to be deployed using AWS Cloud Formation with consistent tagging Management requires cost center numbers and project ID numbers for all existing and future DynamoDB tables and RDS instances
Which strategy should the solutions architect provide to meet these requirements?

1. A. Use Tag Editor to tag existing resources Create cost allocation tags to define the cost center and project ID and allow 24 hours for tags to propagate to existing resources
2. B. Use an AWS Config rule to alert the finance team of untagged resources Create a centralized AWS Lambda based solution to tag untagged RDS databases and DynamoDB resources every hour using a cross-account rote.
3. C. Use Tag Editor to tag existing resources Create cost allocation tags to define the cost center and project ID Use SCPs to restrict resource creation that do not have the cost center and project ID on the resource.
4. D. Create cost allocation tags to define the cost center and project ID and allow 24 hours for tags to propagate to existing resources Update existing federated roles to restrict privileges to provision resources that do not include the cost center and project ID on the resource

Correct Answer: B
