AWS - S3 Fundamentals

You tried to create a bucket with this command:

aws s3api create-bucket --bucket 123_invalid_bucket --region us-east-1

But it failed. What is the most likely reason?

ABucket name contains underscores which are invalid

BBucket name starts with numbers which is not allowed

CRegion us-east-1 does not support bucket creation

DMissing --acl parameter causes failure

Step-by-Step Solution

Solution:

Step 1: Review bucket naming rules
Bucket names cannot contain underscores (_) but can start with numbers.
Step 2: Check command and region validity
Region us-east-1 supports bucket creation and --acl is optional, so failure is due to invalid underscore in name.
Final Answer:
Bucket name contains underscores which are invalid -> Option A
Quick Check:
Underscores not allowed in bucket names [OK]

Quick Trick: Bucket names cannot have underscores, even if starting with numbers [OK]
