You have written a server-side Node.js application and a web application with an HTML/JavaScript front end that uses the Angular.js Framework. The server-side application connects to an Amazon Redshift cluster, issue queries, and then returns the results to the front end for display. Your user base is very large and distributed, but it is important to keep the cost of running this application low.
Which deployment strategy is both technically valid and the most cost-effective?
A. Deploy an AWS Elastic Beanstalk application with two environments: one for the Node.js application and another for the web front end. Launch an Amazon Redshift cluster, and point your application to its
Java Database connectivity (JDBC) endpoint
B. Deploy an AWS OpsWorks stack with three layers: a static web server layer for your front end, a Node.js app server layer for your server-side application, and a Redshift DB layer Amazon Redshift cluster
C. Upload the HTML, CSS, images, and JavaScript for the front end to an Amazon Simple Storage Service (S3) bucket. Create an Amazon CloudFront distribution with this bucket as its origin. Use AWS Elastic Beanstalk to deploy the Node.js application. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint
D. Upload the HTML, CSS, images, and JavaScript for the front end, plus the Node.js code for the server-side application, to an Amazon S3 bucket. Create a CloudFront distribution with this bucket as its origin. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint
E. Upload the HTML, CSS, images, and JavaScript for the front end to an Amazon S3 bucket. Use AWS Elastic Beanstalk to deploy the Node.js application. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint

B. In the source bundle's .ebextensions folder, create a file with a .config extension. In the file, under the "packages" section and "msi" package manager, include the package's URL
C. Launch a new Amazon EC2 instance from the AMI used by the environment. Log into the instance, install the package and run sysprep. Create a new AMI. Configure the environment to use the new AMI

You have been tasked with implementing an automated data backup solution for your application servers that run on Amazon EC2 with Amazon EBS volumes. You want to use a distributed data store for your backups to avoid single points of failure and to increase the durability of the data. Daily backups should be retained for 30 days so that you can restore data within an hour.
How can you implement this through a script that a scheduling deamon runs daily on the application servers?
A. Write the script to call the ec2-create-volume API, tag the Amazon EBS volume with the current data time group, and copy backup data to a second Amazon EBS volume. Use the ec2-describe- volumes API to enumerate existing backup volumes. Call the ec2-delete-volume API to prune backup volumes that are tagged with a date-time group older than 30 days
B. Write the script to call the Amazon Glacier upload archive API, and tag the backup archive with the current date-time group. Use the list vaults API to enumerate existing backup archives. Call the delete vault API to prune backup archives that are tagged with a date-time group older than 30 days
C. Write the script to call the ec2-create-snapshot API, and tag the Amazon EBS snapshot with the current date-time group. Use the ec2-describe-snapshot API to enumerate existing Amazon EBS snapshots. Call the ec2-delete-snapshot API to prune Amazon EBs snapshots that are tagged with a date-time group older than 30 days
D. Write the script to call the ec2-create-volume API, tag the Amazon EBS volume with the current date-time group, and use the ec2-copy-snapshot API to backup data to the new Amazon EBS volume. Use the ec2-describe-snapshot API to enumerate existing backup volumes. Call the ec2- delete-snapshot API to prune backup Amazon EBS volumes that are tagged with a date-time group older than 30 days
