Question : HadoopExam.com needs to comply with SOX by storing certain audit reports of the last few years. The reports are of huge size and may be required only for an internal audit. How can the organization save the storage cost by uploading to AWS? 1. Store with AWS Glacier 2. Store with AWS S3 3. Access Mostly Uused Products by 50000+ Subscribers 4. Store with AWS RRS
Explanation: AWS Glacier is a long term cheaper archival service which is used for infrequent user storage. It is much cheaper than S3 and RRS. If the usage of the data is infrequent, Glacier is probably the best solution.
Explanation: To help manage EC2 instances as well as their usage in a better way, the user can tag the instances. The tags are metadata assigned by the user which consists of a key and a value. One resource can have a maximum of 10 tags.
Explanation: The user can enable logging, versioning as well as change the S3 storage class from the AWS console. The user can encrypt the data using the console, but cannot enable or disable the checksum as it is internally managed by AWS S3.
