REST or Query requests are HTTP or HTTPS requests that use an HTTP verb (such as GET or POST) and a parameter named Action or Operation that specifies the API you are calling.

Do the Amazon EBS volumes persist independently from the running life of an Amazon EC2 instance?

• A.Yes
• B.Only if instructed to when created
• C.No

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 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
• B.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
• C.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
• 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

An organization uses a custom map reduce application to build monthly reports based on many small data files in an Amazon S3 bucket. The data is submitted from various business units on a frequent but unpredictable schedule. As the dataset continues to grow, it becomes increasingly difficult to process all of the data in one day. The organization has scaled up its Amazon EMR cluster, but other optimizations could improve performance.
The organization needs to improve performance minimal changes to existing processes and applications.
What action should the organization take?

• A.Use Amazon S3 Event Notifications and AWS Lambda to create a quick search file index in DynamoDB.
• B.Have business units submit data via Amazon Kinesis Firehose to aggregate data hourly into Amazon S3.
• C.Schedule a daily AWS Data Pipeline process that aggregates content into larger files using S3DistCp.
• D.Add Spark to the Amazon EMR cluster and utilize Resilient Distributed Datasets in-memory.
• E.Use Amazon S3 Event Notifications and AWS Lambda to index each file into an Amazon Elasticsearch Service cluster.
