A Developer Is Adding a Feature to a Client-Side Application

question 68

Multiple Choice

A developer is adding a feature to a client-side application so that users can upload videos to an Amazon S3 bucket. What is the MOST secure way to give the application the ability to write files to the S3 bucket?

• A) Update the S3 bucket policy to allow public write access. Allow any user to upload videos by removing the need to handle user authentication within the client-side application.
• B) Create a new IAM policy and a corresponding IAM user with permissions to write to the S3 bucket. Store the key and the secret for the user in the application code. Use the key to authenticate the video uploads.
• C) Configure the API layer of the application to have a new endpoint that creates signed URLs that allow an object to be put into the S3 bucket. Generate a presigned URL through this API call in the client application. Upload the video by using the signed URL.
• D) Generate a new IAM key and a corresponding secret by using the AWS account root user credentials. Store the key and the secret for the user in the application code. Use the key to authenticate the video uploads.
