The company wants to optimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should be used?

    Answer options:

    B.

    S3 Standard-Infrequent Access (S3 Standard-IA)

    C.

    S3 Intelligent-Tiering

    D.

    S3 Glacier Flexible Retrieval

    How to approach this question

    Keywords: 'unpredictable access patterns', 'optimize costs', 'no retrieval fees'. This is the exact definition of Intelligent-Tiering.

    Full Answer

    Amazon S3 Intelligent-Tiering is designed to optimize costs by automatically moving data to the most cost-effective access tier, without performance impact or operational overhead. It is ideal for data with unknown or changing access patterns and does not charge retrieval fees.
