Q1136. A company wants to store 100 TB of data in an Amazon S3 bucket for an indefinite period of time.The user access patterns for the data are unpredictable. Users require instant access to the data when required.Which solution will meet these requirements MOST cost-effectively?

• A. Store the data in the S3 Standard storage class. Create an S3 Lifecycle policy to move objects to S3 Glacier Deep Archive after 1 week.
• B. Store the data in the S3 Intelligent-Tiering storage class. Enable the S3 Glacier Deep Archive Access access tier. ✓
• C. Store the data in the S3 Standard storage class. Create an S3 Lifecycle policy to move objects to S3 Express One Zone after 1 week.
• D. Store the data in the S3 Intelligent-Tiering storage class. Disable the Archive Access access tier and the Deep Archive Access access tier.

Correct Answer: B. Store the data in the S3 Intelligent-Tiering storage class. Enable the S3 Glacier Deep Archive Access access tier.

Explanation

The solution that will meet the requirements for storing 100 TB of data in Amazon S3 with unpredictable access patterns while ensuring instant access to the data is:B. Store the data in the S3 Intelligent-Tiering storage class. Enable the S3 Glacier Deep Archive Access access tier.Explanation:S3 Intelligent-Tiering: This storage class automatically moves data between two access tiers (frequent and infrequent) based on changing access patterns, allowing for cost savings without sacrificing immediate access to the data.Glacier Deep Archive Access Tier: Enabling this tier allows for instant access to data that might get archived, providing flexibility in case access patterns change or if some data needs to be accessed regularly.Why Other Options Are Not Suitable:A: While S3 Standard provides instant access, moving data to S3 Glacier Deep Archive after a week would not meet the requirement for immediate access, as data in Glacier cannot be accessed instantly and requires retrieval time.C: The S3 Express One Zone storage class is designed for lower-cost storage but does not provide the same redundancy and availability as S3 Standard. Additionally, moving data to this class after a week would not provide instant access when needed.D: Disabling the Archive Access and Deep Archive Access tiers in the S3 Intelligent-Tiering class would negate the benefits of using this storage class for cost-effectiveness without impacting access speed.Thus, option B provides the most cost-effective solution while ensuring that the data remains instantly accessible as required.
