You want to export objects in an S3 bucket using the AWS Snowball Management Console. Assume you have a bucket containing the following objects, sorted in UTF-8 binary order:
01
Aardvark
Aardwolf
Aasvogel/apple
Aasvogel/banana
Aasvogel/cherry
Banana
Car
What happens if you specify no beginning range and set Aasvogel as the ending range?

Objects Aasvogel/apple, Aasvogel/banana and Aasvogel/cherry are exported.
Objects 01, Aardvark, and Aardwolf are exported.
Objects 01, Aardvark, Aardwolf, Aasvogel/apple, Aasvogel/banana and Aasvogel/cherry are exported.

Answer(s): D

Explanation:

When you create an export job in the AWS Snowball Management Console, you can choose to export an entire Amazon S3 bucket or a specific range of objects keys. To export a range, you define the length of the range by providing either an inclusive range beginning, an inclusive range ending, or both. Ranges are UTF-8 binary sorted.
