A recent security audit revealed that the web application is accessible by using both CloudFront and ALB endpoints. However. the company requires that the web application must be accessible only by using the CloudFront endpoint.

Which solution will meet this requirement with the LEAST amount of effort?

A.

Create a new security group and attach it to the CloudFront distribution. Update the ALB security group ingress to allow access only from the CloudFront security group.

B.

Update ALB security group ingress to allow access only from the CloudFront managed prefix list.

Question # 67

A retail company is operating its ecommerce application on AWS. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The company uses an Amazon RDS DB instance as the database backend. Amazon CloudFront is configured with one origin that points to the ALB. Static content is cached.

Question # 92

An international delivery company hosts a delivery management system on AWS. Drivers use the system to upload confirmation of delivery. Confirmation includes the recipient's signature or a photo of the package with the recipient. The driver's handheld device uploads signatures and photos through FTP to a single Amazon EC2 instance. Each handheld device saves a file in a directory based on the signed-in user, and the file name matches the delivery number. The EC2 instance then adds metadata to the file after querying a central database to pull delivery information. The file is then placed in Amazon S3 for archiving.

As the company expands, drivers report that the system is rejecting connections. The FTP server is having problems because of dropped connections and memory issues. In response to these problems, a system engineer schedules a cron task to reboot the EC2 instance every 30 minutes. The billing team reports that files are not always in the archive and that the central system is not always updated.

A solutions architect needs to design a solution that maximizes scalability to ensure that the archive always receives the files and that systems are always updated. The handheld devices cannot be modified, so the company cannot deploy a new application.

Which solution will meet these requirements?

A.

Use VM Import/Export to import the application server VM.

C.

Export the VM images to an AWS Snowball Edge Storage Optimized device.

D.

Use an AWS Server Migration Service (AWS SMS) replication job to migrate the application server VM to AWS.

Question # 165

A company wants to migrate to AWS. The company is running thousands of VMs in a VMware ESXi environment. The company has no configuration management database and has little Knowledge about the utilization of the VMware portfolio.

A solutions architect must provide the company with an accurate inventory so that the company can plan for a cost-effective migration.

Which solution will meet these requirements with the LEAST operational overhead?

A.

Use AWS Systems Manager Patch Manager to deploy Migration Evaluator to each VM. Review the collected data in Amazon QuickSight. Identify servers that have high utilization. Remove the servers that have high utilization from the migration list. Import the data to AWS Migration Hub.

B.

Export the VMware portfolio to a csv file. Check the disk utilization for each server. Remove servers that have high utilization. Export the data to AWS Application Migration Service. Use AWS Server Migration Service (AWS SMS) to migrate the remaining servers.

C.

Deploy the Migration Evaluator agentless collector to the ESXi hypervisor. Review the collected data in Migration Evaluator. Identify inactive servers. Remove the inactive servers from the migration list. Import the data to AWS Migration Hub.

D.

Deploy the AWS Application Migration Service Agent to each VM. When the data is collected, use Amazon Redshift to import and analyze the data. Use Amazon QuickSight for data visualization.

Question # 166

A company uses AWS Organizations for a multi-account setup in the AWS Cloud. The company's finance team has a data processing application that uses AWS Lambda and Amazon DynamoDB. The company's marketing team wants to access the data that is stored in the DynamoDB table.

The DynamoDB table contains confidential data. The marketing team can have access to only specific attributes of data in the DynamoDB table. The fi-nance team and the marketing team have separate AWS accounts.

What should a solutions architect do to provide the marketing team with the appropriate access to the DynamoDB table?

A.

Create an SCP to grant the marketing team's AWS account access to the specific attributes of the DynamoDB table. Attach the SCP to the OU of the finance team.

B.

Create an IAM role in the finance team's account by using IAM policy conditions for specific DynamoDB attributes (fine-grained access con-trol). Establish trust with the marketing team's account. In the mar-keting team's account, create an IAM role that has permissions to as-sume the IAM role in the finance team's account.

C.

Create a resource-based IAM policy that includes conditions for spe-cific DynamoDB attributes (fine-grained access control). Attach the policy to the DynamoDB table. In the marketing team's account, create an IAM role that has permissions to access the DynamoDB table in the finance team's account.

D.

Create an IAM role in the finance team's account to access the Dyna-moDB table. Use an IAM permissions boundary to limit the access to the specific attributes. In the marketing team's account, create an IAM role that has permissions to assume the IAM role in the finance team's account.

Question # 167

A solutions architect has created a single VPC on AWS. The VPC has one internet gateway and one NAT gateway. The VPC extends across three Availability Zones. Each Availability Zone includes one public subnet and one private subnet. The three private subnets contain Amazon EC2 instances that must be able to connect to the internet.

Which solution will increase the network resiliency of this architecture?

A.

Add two NAT gateways so that each Availability Zone has a NAT gateway. Configure a route table for each private subnet to send traffic to the NAT gateway in the subnet's Availability Zone.

B.

Add two NAT gateways so that each Availability Zone has a NAT gateway. Configure a route table for each public subnet to send traffic to the NAT gateway in the subnet's Availability Zone.

C.

Add two internet gateways so that each Availability Zone has an internet gateway. Configure a route table for each private subnet to send traffic to the internet gateway in the subnet's Availability Zone.

D.

Add two internet gateways so that each Availability Zone has an internet gateway. Configure a route table for each public subnet to send traffic to the internet gateway in the subnet's Availability Zone.

Question # 170

A company has an application that uses Amazon EC2 instances in an Auto Scaling group. The quality assurance (QA) department needs to launch and test the application. The application environments are currently launched by the manager of the department using an AWS CloudFormation template. To launch the stack, the manager uses a role with permission to use CloudFormation, EC2, and Auto Scaling APIs. The manager wants to allow QA to launch environments, but does not want to grant broad permissions to each user.

Which set up would achieve these goals?

A.

Upload the AWS CloudFormation template to Amazon S3. Give users in the QA department permission to assume the manager's role, restricts the permissions to the template and the resources it creates. Train users to launch the template from the CloudFormation console.

B.

Create an AWS Service Catalog product from the environment template. Add a launch constraint to the product with the existing manager's department permission to use AWS Service Catalog APIs only. Train users to launch the template from the AWS Service Catalog console.

C.

Upload the AWS CloudFormation template to Amazon S3. Give users in the QA department permission to use CloudFormation and restrict the permissions to the template and the resources it creates. Train users to launch the template from the CloudFormation console.

D.

Create an AWS Elastic Beanstalk application from the environment template. Give users in the QA department permission to use Elastic Beanstalk only. Train users to launch Elastic Beanstalk environments with the Elastic Beanstalk CLI, passing the existing role to the environment.
