A . Create an S3 Lifecycle policy to transition the images to S3 Glacier after 7 days
B . Create an S3 Lifecycle policy to transition the images to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 7 days
C . Create an S3 Lifecycle policy to transition the images to S3 Standard after 7 days
D . Create an S3 Lifecycle policy to transition the images to S3 Standard-Infrequent Access (S3 Standard-IA) after 7 days

Answer: D

Explanation:

To reduce S3 storage costs while ensuring the images remain highly available and immediately accessible, transitioning the images to S3 Standard-IA after 7 days is the most cost-effective solution.

Understand Storage Classes:

S3 Standard-IA (Infrequent Access) is designed for data that is accessed less frequently but requires rapid access when needed. It offers lower storage costs compared to S3 Standard, but higher retrieval costs.

Reference: Amazon S3 Storage Classes

Create a Lifecycle Policy:

Navigate to the S3 console and select the bucket storing the images.

Go to the "Management" tab and select "Lifecycle".

Create a new lifecycle rule. Set the rule to transition objects to S3 Standard-IA 7 days after creation.

Reference: Managing your storage lifecycle

Configure the Transition:

In the Lifecycle rule configuration, add a "Transition" action.

Specify the transition to S3 Standard-IA and set the number of days to 7.

Save and apply the rule.

This setup ensures that images are stored in the cost-effective S3 Standard-IA storage class after their initial period of high access, meeting the requirement of high availability and immediate access.
