Question 3

A developer wants to store image files in a bucket that is called images-bucket, but receives the error BucketAlreadyExists. Which action must the developer take to resolve this error?

Bucket names are unique to the Region that they are created in. If the requested bucket name is not available, the developer must create the images-bucket in a different Region.
The developer must contact AWS Support to request approval to use the same bucket name.
Bucket names go to the highest bidder. The developer must outbid the current bucket owner.
Bucket names are globally unique. If the requested bucket name is not available, the developer must rename the bucket.

Bucket names are globally unique. If the requested bucket name is not available, the developer must rename the bucket.

Question 4

A developer is using Amazon Simple Storage Service (Amazon S3) to host a static website in a bucket that is called frank-martha-cafe. This bucket is in the us-east-1 Region. Which URL is the virtual-hosted-style URL for the website?

https://frank-martha-cafe.s3-us-east-1.amazonaws.com
https://frank-martha-cafe.s3-website-us-east-1.amazonaws.com

They also want to follow AWS recommendations for granting permissions. Which mechanism should the developer apply to the bucket?

Cross-Origin resource Sharing (CORS)
Bucket access control list (ACL)
IAM policy
*Bucket policy

Question 8

A developer wants to allow a user to download private objects directly from an Amazon Simple Storage Service (Amazon S3) bucket without needing AWS security credentials or permissions. What can the developer share with the user to grant them time-limited access to the objects?

A temporary token

The bucket endpoint URL
A presigned URL

A presigned URL provides access to PUT or GET objects without granting permissions to perform any other actions.

Secure Sockets Layer/Transport Layer Security (SSL/TLS)
Server-Side Encryption with AWS KMS-Managed Keys (SSE-KMS)

Question 10

A developer hosts a static website in an Amazon Simple Storage Service (Amazon S3) bucket. The website references image objects in another S3 bucket. However, these images do not display on the website. What could be the problem?
