Why does AWS recommend that you delete Snowball logs once the job that the logs are associated with enters the completed status?

  1. To avoid running out of local disk space
  2. Because they contain potentially sensitive information
  3. Because you will be charged for additional s3 storage
  4. To avoid thrashing that would slow down the migration process

Answer(s): B

Explanation:

Snowball logs are saved in plaintext format and contain the names of the files and paths, for the files that are transferred. This is potentially sensitive information, so AWS strongly suggests that you delete these logs once the job that the logs are associated with enters the completed status.

How do you indicate where to send your Snowball once your data has been loaded to it?

  1. Print the return label via the AWS Console and stick it on the Snowball.
  2. Turn it off. The E Ink will display changes to the return label. Then ship it to Amazon.
  3. Use the E Ink display interface and select the “Return Snowball” option for the label. Then ship it to Amazon.
  4. Pack it in a box with the prepaid shipping label that came with it.

Answer(s): B

Explanation:

Snowballs don’t need to be packed in a box or container because it already has its own physically rugged shipping container. The E Ink display on the front of the Snowball changes to your return shipping label when the Snowball is turned off.
