Q

What are some of the key characteristics of Amazon S3? Choose 3.

  1. Data is stored as objects within resources called “buckets”
  2. With S3 Versioning, you can easily preserve, retrieve, and restore every version of an object stored in Amazon S3
  3. With S3 Cross-Region Replication (CRR), you can replicate objects (and their respective metadata and object tags) into other AWS Regions
  4. S3 can be attached to an EC2 instance to provide block storage

Q

A construction engineering company wants to leverage cloud storage to store their large architecture blueprints files which are saved as pdfs in network shared folder through a collaboration application between project team members. The blueprint files for the active projects should be accessible fast while files pertaining to completed projects are not accessed frequently. What is the best cloud storage solution for them which will work with existing application?

  1. Store latest project files in s3-Standard and store files more than one month old S3-IA. Create a life cycle policy to move files accordingly.
  2. Install an AWS Storage volume gateway in cached mode.

Q

A law firm has an internal tablet/mobile application used by employees to download large word documents in their devices for offline review. These document’s size are in the range of 10-20 MB. The employees save the document in local device storage, edit it in offline mode and then use the feature in app to upload file to cloud storage. Most of the time users are expected to be in area of high mobile bandwidth of LTE or WIFI but some time they may be in area using a slow speed network (EDGE) or 3G with lots of fluctuations. The files are stored in AWS S3 buckets. What approach should the architect recommend for file upload in application?

  1. Use Single PUT operation to upload the files to S3
  2. Use Multipart upload to upload the files to S3
  3. Use Amazon S3 Transfer Acceleration to upload the files
  4. Use Single POST operation to upload the files to S3

Q

What are the recommended scenarios to use multipart uploading to S3? Choose 2.

  1. If you’re uploading any size objects over a stable high-bandwidth network, use multipart uploading to maximize the use of your available bandwidth by uploading object parts in parallel for multi-threaded performance.
  2. If you’re uploading large objects over a stable high-bandwidth network, use multipart uploading to maximize the use of your available bandwidth by uploading object parts in parallel for multi-threaded performance.
  3. If you’re uploading over a stable high-bandwidth network, use multipart uploading to increase resiliency to network errors by avoiding upload restarts.
  4. If you’re uploading over a spotty network, use multipart uploading to increase resiliency to network errors by avoiding upload restarts.

How does versioning-enabled buckets enable you to recover objects from accidental deletion or overwrite? Choose 2. 1. If you delete or overwrite an object AWS keeps a copy in the archive folder. 2. If you delete an object, instead of removing it permanently, Amazon S3 inserts a delete marker, which becomes the current object version. 3. If you overwrite an object, it results in a new object version in the bucket. 4. If you delete or overwrite an object AWS emails you a copy of the previous version.

How S3 evaluates request for a bucket operation requested by an IAM Principal whose parent AWS account is also the bucket owner? Principal: Jill Jill’s Parent Account: 1111-1111-1111 In the user context Amazon S3 evaluates all policies that belongs to the parent AWS account to determine if Principal has permission to perform the operation. 1. Amazon S3 evaluates the user context by reviewing the policies authored by the account to verify that Principal has the necessary permissions, then it evaluates the bucket context, to verify that bucket owner has granted Jill (or her parent AWS account) permission to perform the requested operation. 2. Amazon S3 evaluates the user context by reviewing the policies authored by the account to verify that Principal has the necessary permissions, then it evaluates the bucket context, to verify that bucket owner has granted Jill (or her parent AWS account) permission to perform the requested operation and last object context evaluates the object ACL to determine if Jill has permission to access the objects in the bucket. 3. Amazon S3 evaluates the bucket context, to verify that bucket owner has granted Jill (or her parent AWS account) permission to perform the requested operation and in object context evaluates the object ACL to determine if Jill has permission to access the objects in the bucket.

When should you choose Bucket policy for S3 permissions? Choose 4. 1. If you’re more interested in “What can this user do in AWS?” 2. If you’re more interested in “Who can access this S3 bucket?” 3. You want a simple way to grant cross-account access to your S3 environment, without using IAM roles. 4. Your IAM policies are reaching the size limit (up to 2 kb for users, 5 kb for groups, and 10 kb for roles). S3 supports bucket policies of up 20 kb. 5. You prefer to keep access control policies in the S3 environment.
