Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 19 discussion

Answer is C, Cross region replication(CRR) or Same region replication(SRR) needs S3 versioning to be enabled.

Explanation Replication enables automatic, asynchronous copying of objects across Amazon S3 buckets. Buckets that are configured for object replication can be owned by the same AWS account or by different accounts. You can copy objects between different AWS Regions or within the same Region. Both source and destination buckets must have versioning enabled. CORRECT: "Create an additional S3 bucket with versioning in another Region and configure cross-Region replication" is the correct answer. INCORRECT: "Create an additional S3 bucket in another Region and configure cross-Region replication" is incorrect as the destination bucket must also have versioning enabled. INCORRECT: "Create an additional S3 bucket in another Region and configure cross-origin resource sharing (CORS)" is incorrect as CORS is not related to replication. INCORRECT: "Create an additional S3 bucket with versioning in another Region and configure cross-origin resource sharing (CORS)" is incorrect as CORS is not related to replication.

Answer C Clue - For enabling cross region replication, versioning must be enabled. Cross region replication will take care of copying data in other S3 bucket in different region.

ANSWER IS C , Creating a new S3 bucket in another AWS Region. Setting up S3 Cross-Region Replication (CRR) between the two buckets with versioning enabled. This will ensure that changes made to the dataset in the primary bucket are automatically replicated to the secondary bucket in the other region. Configuring Amazon S3 versioning to track changes to objects in the bucket. This will ensure that all versions of an object are stored, even if they are deleted, which can help with disaster recovery efforts. By using S3 CRR and versioning, the solutions architect can ensure that the business-critical dataset is stored in multiple AWS Regions, meeting the company's disaster recovery policy.

CORS is for a different use case.

Ccccccc

c. cross-Region replication.

this appeared in my exam taken 3 June 2021 I picked C

Ans is C, as in neal

C for sure. Cross region replication

Answer is C for sure cross region replication can be enabled to replicate data across multiple regions. Also, key requirement for cross-region replication is the bucket should have versioning enabled.

Looks C to me

it's C

Ans=D https://www.stratoscale.com/blog/storage/replicate-s3-buckets-across-regions/#:~:text=In%20order%20to%20set%20up,buckets%20must%20have%20versioning%20enabled.&text=To%20set%20up%20object%20replication,in%20the%20Amazon%20S3%20console

C right

For Cross Region Replication, you must have versioning turned on for both the source and destination buckets

Agree that for cross region replication to happen, versioning must be enabled.
