  A web design company currently runs several FTP servers that their 250 customers use to upload and download large graphic files. They wish to move this system to AWS to make it more scalable, but they wish to maintain customer privacy and keep costs to a minimum. What AWS architecture would you recommend?

  • AAsk their customers to use an S3 client instead of an FTP client. Create a single S3 bucket. Create an IAM user for each customer. Put the IAM Users in a Group that has an IAM policy that permits access to sub-directories within the bucket via use of the 'username' Policy variable.
  • BCreate a single S3 bucket with Reduced Redundancy Storage turned on and ask their customers to use an S3 client instead of an FTP client. Create a bucket for each customer with a Bucket Policy that permits access only to that one customer.
  • CCreate an auto-scaling group of FTP servers with a scaling policy to automatically scale-in when minimum network traffic on the auto-scaling group is below a given threshold. Load a central list of ftp users from S3 as part of the user Data startup script on each Instance.
  • DCreate a single S3 bucket with Requester Pays turned on and ask their customers to use an S3 client instead of an FTP client. Create a bucket for each customer with a Bucket Policy that permits access only to that one customer.

  Your startup wants to implement an order fulfillment process for selling a personalized gadget that needs an average of 3-4 days to produce with some orders taking up to 6 months. You expect 10 orders per day on your first day, 1000 orders per day after 6 months and 10,000 orders after 12 months. Orders coming in are checked for consistency, then dispatched to your manufacturing plant for production, quality control, packaging, shipment and payment processing. If the product does not meet the quality standards at any stage of the process, employees may force the process to repeat a step. Customers are notified via email about order status and any critical issues with their orders such as payment failure. Your base architecture includes AWS Elastic Beanstalk for your website with an RDS MySQL instance for customer data and orders. How can you implement the order fulfillment process while making sure that the emails are delivered reliably?

  • AAdd a business process management application to your Elastic Beanstalk app servers and re-use the RDS database for tracking order status. Use one of the Elastic Beanstalk instances to send emails to customers.
  • BUse SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1. Use the decider instance to send emails to customers.
  • CUse SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1. Use SES to send emails to customers.
  • DUse an SQS queue to manage all process tasks. Use an Auto Scaling group of EC2 Instances that poll the tasks and execute them. Use SES to send emails to customers.

  An AWS customer is deploying an application that is composed of an AutoScaling group of EC2 Instances. The customers security policy requires that every outbound connection from these instances to any other service within the customers Virtual Private Cloud must be authenticated using a unique x 509 certificate that contains the specific instance-id. In addition an x 509 certificates must be designed by the customer's Key management service in order to be trusted for authentication. Which of the following configurations will support these requirements?

  • AConfigure an IAM Role that grants access to an Amazon S3 object containing a signed certificate and configure the Auto Scaling group to launch instances with this role Have the instances bootstrap get the certificate from Amazon S3 upon first boot.
  • BEmbed a certificate into the Amazon Machine Image that is used by the Auto Scaling group Have the launched instances generate a certificate signature request with the instance's assigned instance- id to the Key management service for signature.
  • CConfigure the Auto Scaling group to send an SNS notification of the launch of a new instance to the trusted key management service. Have the Key management service generate a signed certificate and send it directly to the newly launched instance.
  • DConfigure the launched instances to generate a new certificate upon first boot Have the Key management service poll the AutoScaling group for associated instances and send new instances a certificate signature that contains the specific instance-id.
