You have a 25 GB file that you're trying to upload to S3 but you're getting errors. What is a possible solution for this?

• The file size limit on S3 is 5 GB

• Update your bucket policy to allow the larger file

• Use Multi-Part upload when uploading files larger than 5GB

• Encrypt the file

Answer explanation

Multi-Part Upload is recommended as soon as the file is over 100 MB.

You're getting errors while trying to create a new S3 bucket named dev. You're using a new AWS Account with no S3 buckets created before. What is a possible cause for this?

• You're missing IAM permissions to create an S3 bucket

• S3 bucket names must be globally unique and dev is already taken

You have enabled versioning in your S3 bucket which already contains a lot of files. Which version will the existing files have?

• 1

• 0

• -1

• null

You have updated an S3 bucket policy to allow IAM users to read/write files in the S3 bucket, but one of the users complain that he can't perform a PutObject API call. What is a possible cause for this?

• The S3 bucket policy must be wrong

• The user is lacking permissions

• The IAM user must have an explicit DENY in the attached IAM Policy

• You need to contact AWS Support to lift this limit

Answer explanation

Explicit DENY in an IAM Policy will take precedence over an S3 bucket policy.

You want the content of an S3 bucket to be fully available in different AWS Regions. That will help your team perform data analysis at the lowest latency and cost possible. What S3 feature should you use?

• Amazon CloudFront Distributions

• S3 Replication

• S3 Versioning

• S3 Static Website Hosting

Answer explanation

S3 Replication allows you to replicate data from an S3 bucket to another in the same/different AWS Region.

You have 3 S3 buckets. One source bucket A, and two destination buckets B and C in different AWS Regions. You want to replicate objects from bucket A to both bucket B and C. How would you achieve this?

• Configure replication from bucket A to bucket B, then from bucket A to bucket C

• Configure replication from bucket A to bucket B, then from bucket B to bucket C

• Configure replication from bucket A to bucket C, then from bucket C to bucket B
