AWS - S3 Fundamentals

You wrote this bucket policy but users still cannot upload files:

{
  "Effect": "Allow",
  "Principal": "*",
  "Action": "s3:PutObject",
  "Resource": "arn:aws:s3:::example-bucket"
}

What is the problem?

AThe Resource ARN is missing the /* to specify objects

BThe Action s3:PutObject is invalid

CThe Principal cannot be * for uploads

DEffect should be Deny to allow uploads

Step-by-Step Solution

Solution:

Step 1: Check the Resource ARN format
To allow object uploads, Resource must include "/*" to specify objects inside the bucket.
Step 2: Validate Action and Principal
s3:PutObject is valid, Principal "*" is allowed, and Effect "Allow" is correct.
Final Answer:
The Resource ARN is missing the /* to specify objects -> Option A
Quick Check:
PutObject needs resource with /* [OK]

Quick Trick: Resource must end with /* for object actions [OK]
