What is the best solution that the Architect can provide to them?

A Solutions Architect is working for a financial company. The manager wants to have the ability to automatically transfer obsolete data from their S3 bucket to a low-cost storage system in AWS .

What is the best solution that the Architect can provide to them?
A . Use Lifecycle Policies in S3 to move obsolete data to Glacier.
B . Use CloudEndure Migration.
C . Use Amazon SQ
E . Use an EC2 instance and a scheduled job to transfer the obsolete data from their S3 location to
Amazon S3 Glacier.

Answer: A

Explanation:

In this scenario, you can use lifecycle policies in S3 to automatically move obsolete data to Glacier. Lifecycle configuration in Amazon S3 enables you to specify the lifecycle management of objects in a bucket. The configuration is a set of one or more rules, where each rule defines an action for Amazon S3 to apply to a group of objects.

These actions can be classified as follows:

Transition actions C In which you define when objects transition to another storage class. For example, you may choose to transition objects to the STANDARD_IA (IA, for infrequent access) storage class 30 days after creation, or archive objects to the GLACIER storage class one year after creation.

Expiration actions C In which you specify when the objects expire. Then Amazon S3 deletes the expired objects on your behalf.

The option that says: Use an EC2 instance and a scheduled job to transfer the obsolete data from their S3 location to Amazon S3 Glacier is incorrect because you don’t need to create a scheduled job in EC2 as you can simply use the lifecycle policy in S3.

The option that says: Use Amazon SQS is incorrect as SQS is not a storage service. Amazon SQS is

primarily used to decouple your applications by queueing the incoming requests of your application.

The option that says: Use CloudEndure Migration is incorrect because this service is just a highly

automated lift-and-shift (rehost) solution that simplifies, expedites, and reduces the cost of migrating

applications to AWS. You cannot use this to automatically transition your S3 objects to a cheaper

storage class.
