  1. Which of the following statements regarding S3 storage classes is true?

    A. The availability of S3 and S3-IA is the same.
    B. The durability of S3 and S3-IA is the same.
    C. The latency of S3 and Glacier is the same.
    D. The latency of S3 is greater than that of Glacier.

Answer:B
This is a common question on AWS exams, and relates to your understanding of the various S3 classes. S3 and S3-IA have the same durability, but the availability of S3 is one 9 greater than S3-IA. S3 has 99.99 availability, while S3-IA has 99.9 availability. Glacier has much greater first-byte latency than S3, so both C and D are false.
