AWS - S3 Fundamentals
A user tries to upload a file to S3 with the command: aws s3 cp data.csv s3://mybucket/ --storage-class GLACIER but gets an error. What is the likely cause?
AGLACIER is not a valid storage class for direct upload via this command.
BThe bucket name is invalid.
CThe file data.csv does not exist locally.
DThe AWS CLI version does not support storage classes.
Step-by-Step Solution

GLACIER is not a valid storage class for direct upload via this command. -> Option A

Direct upload with GLACIER = error [OK]
Quick Trick:GLACIER needs lifecycle or special upload, not direct CLI copy [OK]
Common Mistakes:

Ignoring file existence errors
Blaming bucket name without checking
