Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company has copied 1 PB of data from a colocation facility to an Amazon S3 bucket in the us-east-1 Region using an AWS Direct Connect link. The company now wants to copy the data to another S3 bucket in the us-west-2 Region. The colocation facility does not allow the use of AWS Snowball.
What should a solutions architect recommend to accomplish this?

A. Order a Snowball Edge device to copy the data from one Region to another Region.
B. Transfer contents from the source S3 bucket to a target S3 bucket using the S3 console.
C. Use the aws S3 sync command to copy data from the source bucket to the destination bucket.
D. Add a cross-Region replication configuration to copy objects across S3 buckets in different Regions.

cannot be C. The link which you shared clearly states following; Note: Using the aws s3 ls or aws s3 sync commands on large buckets (with 10 million objects or more) can be expensive, resulting in a timeout. Thus answer should be D

Configure replication for existing objects To enable existing object replication for your account, you must contact AWS Support and create a technical support case (service: Amazon S3). This is required to ensure that replication is configured correctly. To prevent your request from being delayed, give your AWS Support case the subject “Replication for Existing Objects” and be sure to include the following information: Source bucket Destination bucket Estimated storage volume to replicate (in terabytes) Estimated storage object count to replicate I think D would work based on the current support

Rather, you cannot use CRR once after uploading the object into the bucket. It works only for new objects

A. We can't use Snowball B. Transfer contents from the source S3 bucket to a target S3 bucket using the console is not really viable. C. It sounds like the logical option. D. Cross-region replication is for resiliency, you can't pick a "bucket" as a destination.

They are different, but the idea is the same. I think the company prohibits Snowball because of the way it transfers data to AWS, so Snowball Edge should also be prohibited, since it has the same transfer procedure.

D cannot be the answer. As in CRR, only the new objects created after enabling replication are moved to destination bucket. In this case the files are already there in the source bucket.

Answer D is wrong. https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication.html "By default, replication only supports copying new Amazon S3 objects after it is enabled. You can use replication to copy existing objects and clone them to a different bucket, but in order to do so, you must contact AWS Support Center....."

In fact cross region replication is the recommended way to handle such a case. “ Q. Can I use Snowball Edge to migrate data from one AWS Region to another AWS Region? No. Snowball Edge is intended to serve as a data transport solution for moving high volumes of data into and out of a designated AWS Region. For use cases that require data transfer between AWS Regions, we recommend using S3 Cross-Region Replication as an alternative.” https://aws.amazon.com/snowball/faqs/

But will transfer new data ONLY after enabling CRR.. will not transfer old existing data prior CRR enabled.

That is the default behavior. You can configure it for the batch replication which will copy the existing items as well. CRR is a correct solution for this purpose.

Selected Answer: C

C, Not D, cross-Region replication configuration to copy objects (new object after is is enabled). But you can use Replicate Existing Objects with Amazon S3 Batch Replication https://aws.amazon.com/blogs/aws/new-replicate-existing-objects-with-amazon-s3-batch-replication/ After you finish configure cross-Region replication, it will prompt you if you want to create job for S3 Batch Replication for the existing objects.

Why not D? coz.. Cross region replication will only work on new data AFTER it has been enabled on S3. in this case the data has already been copied before Cross Region replication has been enabled. So C is the ans.

Note: Using the aws s3 ls or aws s3 sync commands on large buckets (with 10 million objects or more) can be expensive, resulting in a timeout. If you encounter timeouts because of a large bucket, then consider using Amazon CloudWatch metrics to calculate the size and number of objects in a bucket. Also, consider using S3 Batch Operations to copy the objects. Considering this statement D should be good for this use case assuming something like AWS Support is missed to be mentioned in the choice
