Your development team wants account-level access to production instances in order to do live debugging of a highly secure environment.
Which of the following should you do?

• A.Place the credentials provided by Amazon EC2 onto an MFA encrypted USB drive, and physically share it with each developer so that the private key never leaves the office.
• B.Place an internally created private key into a secure S3 bucket with server-side encryption using customer keys and configuration management, create a service account on all the instances using this private key, and assign IAM users to each developer so they can download the file.
• C.Place the credentials provided by Amazon Elastic Compute Cloud (EC2) into a secure Amazon Sample Storage Service (S3) bucket with encryption enabled.
  Assign AWS Identity and Access Management (IAM) users to each developer so they can download the credentials file.
• D.Place each developer's own public key into a private S3 bucket, use instance profiles and configuration management to create a user account for each developer on all instances, and place the user's public keys into the appropriate account.

An application is currently writing a large number of records to a DynamoDB table in one region. There is a requirement for a secondary application tojust take in the changes to the DynamoDB table every 2 hours and process the updates accordingly. Which of the following is an ideal way to ensure the secondary application can get the relevant changes from the DynamoDB table.

• A.Inserta timestamp for each record and then scan the entire table for the timestamp asper the last 2 hours.
• B.Createanother DynamoDB table with the records modified in the last 2 hours.
• C.UseDynamoDB streams to monitor the changes in the DynamoDB table.
• D.Transferthe records to S3 which were modified in the last 2 hours

A company must ensure consistent behavior of an application running on Amazon Linux in its corporate ecosystem before moving into AWS. The company has an existing automated server build system using VMware. The goal is to demonstrate the functionality of the application and its prerequisites on the new target operating system.
The DevOps Engineer needs to use the existing corporate server pipeline and virtualization software to create a server image. The server image will be tested on- premises to resemble the build on Amazon EC2 as closely as possible.
How can this be accomplished?

• A.Build an EC2 instance with the latest Amazon Linux operating system, and use the AWS Import/Export service to export the EC2 image to a VMware ISO in Amazon S3. Then import the resulting ISO onto the on-premises system.
• B.Download and integrate the latest ISO of CentOS 7 and execute the application deployment on the resulting server.
• C.Launch an Amazon Linux AMI using an AWS OpsWorks deployment agent onto the on-premises infrastructure, then execute the application deployment.
• D.Download and integrate the latest ISO of Amazon Linux 2 and execute the application deployment on the resulting server. Confirm that operating system testing results are consistent with EC2 operating system behavior.

An Engineering team manages a Node.js e-commerce application. The current environment consists of the following components:
* Amazon S3 buckets for storing content
* Amazon EC2 for the front-end web servers
* AWS Lambda for executing image processing
* Amazon DynamoDB for storing session-related data
The team expects a significant increase in traffic to the site. The application should handle the additional load without interruption. The team ran initial tests by adding new servers to the EC2 front-end to handle the larger load, but the instances took up to 20 minutes to become fully configured. The team wants to reduce this configuration time.
What changes will the Engineering team need to implement to make the solution the MOST resilient and highly available while meeting the expected increase in demand?

• A.Deploy a fleet of EC2 instances, doubling the current capacity, and place them behind an Application Load Balancer. Increase the Amazon DynamoDB read and write capacity units. Add an alias record that contains the Application Load Balancer endpoint to the existing Amazon Route 53 DNS record that points to the application.
• B.Use AWS OpsWorks to automatically configure each new EC2 instance as it is launched. Configure the EC2 instances by using an Auto Scaling group behind an Application Load Balancer across multiple Availability Zones. Implement Amazon DynamoDB Auto Scaling. Use Amazon Route 53 to point the application DNS record to the Application Load Balancer.
• C.Use AWS Elastic Beanstalk with a custom AMI including all web components. Deploy the platform by using an Auto Scaling group behind an Application Load Balancer across multiple Availability Zones.
  Implement Amazon DynamoDB Auto Scaling. Use Amazon Route 53 to point the application DNS record to the Elastic Beanstalk load balancer.
• D.Configure Amazon CloudFront and have its origin point to Amazon S3 to host the web application.
  Implement Amazon DynamoDB Auto Scaling. Use Amazon Route 53 to point the application DNS record to the CloudFront DNS name.
