Your company currently stores documents in an S3 bucket. They want to transfer the files to a low-cost storage unit after a duration of 2 months to save on cost. Which of the following can be used to perform this activity automatically?

Answer options:

A.Use the events of the S3 bucket to transfer the files to Amazon Glacier.
B.Use the events of the S3 bucket to transfer the files to EBS volumes – Cold HDD.C.Use the lifecycle policies of the S3 bucket to transfer the files to Amazon Glacier.
D.Use the lifecycle policies of the S3 bucket to transfer the files to EBS volumes – Cold HDD.

Answer – C
The AWS Documentation mentions the following.
To manage your objects so that they are stored cost-effectively throughout their lifecycle, configure their lifecycle. A lifecycle configuration is a set of rules that define actions that Amazon S3 applies to a group of objects. There are two types of actions.
Transition actions—Define when objects transition to another storage class. For example, you might choose to transition objects to the STANDARD_IA storage class 30 days after you created them or archive objects to the GLACIER storage class one year after creating them.
Expiration actions—Define when objects expire. Amazon S3 deletes expired objects on your behalf.
Options B and D are incorrect because ideally you don’t transfer to EBS volumes – Cold HDD.Option A is incorrect because you need to use lifecycle policies.
