AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Replication

The video tutorial explains Amazon S3 replication, focusing on cross-region replication (CRR) and same-region replication (SRR). It covers the need for enabling versioning, the asynchronous nature of replication, and the use cases for CRR and SRR, such as compliance, disaster recovery, and log aggregation. The tutorial also highlights features like S3 batch replication for existing objects and optional settings for delete markers. Limitations, such as the absence of replication chaining, are discussed to provide a comprehensive understanding of S3 replication.

What is required to enable replication between S3 buckets?

• Enabling versioning in both source and destination buckets

• Disabling versioning in both source and destination buckets

• Enabling versioning only in the source bucket

• Enabling versioning only in the destination bucket

Which of the following is a use case for Cross Region Replication (CRR)?

• Disaster recovery

• Log aggregation across multiple accounts

• Compliance and lower latency access

• Live replication between production and test accounts

What is a feature that allows replication of existing objects in S3?

• S3 instant replication

• S3 manual replication

• S3 batch replication

• S3 continuous replication

What happens to delete markers in S3 replication?

• They can be optionally replicated

• They are never replicated

• They are always replicated

• They are replicated only if versioning is disabled

What is the limitation regarding chaining in S3 replication?

• Objects from bucket one can be replicated to bucket three

• Objects from bucket three can be replicated to bucket one

• Objects from bucket one cannot be replicated to bucket three

• Objects from bucket two can be replicated to bucket one
