You need to establish a secure backup and archiving solution for your company, using AWS. Documents should be immediately accessible for three months and available for five years for compliance reasons.
Which AWS service fulfills these requirements in the most cost-effective way? Choose the correct answer:
A . Upload data to S3 and use lifecycle policies to move the data into Glacier for long-term archiving.
B . Upload the data on EBS, use lifecycle policies to move EBS snapshots into S3 and later into Glacier for long-term archiving.
C . Use Direct Connect to upload data to S3 and use IAM policies to move the data into Glacier for long-term archiving.
D . Use Storage Gateway to store data to S3 and use lifecycle policies to move the data into Redshift for long-term archiving.
Answer: A
Explanation:
amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup. Customers can reliably store large or small amounts of data for as little as $0,004 per gigabyte per month, a significant savings compared to on-premises solutions.
With Amazon lifecycle policies you can create transition actions in which you define when objects transition to another Amazon S3 storage class. For example, you may choose to transition objects to the STANDARDJA (IA, for infrequent access) storage class 30 days after creation, or archive objects to the GLACIER storage class one year after creation.
Option B is invalid because lifecycle policies are not available for EBS volumes
Option C is invalid because IAM policies cannot be used to move data to Glacier
Option D is invalid because lifecycle policies is not used to move data to Redshif
