AWS Certified Cloud Practitioner (CLF-C01)- Amazon S3 Cross Region Replication

The video tutorial covers Amazon S3 cross region replication (CRR), explaining its purpose, benefits, and requirements. CRR allows asynchronous copying of objects across AWS regions, aiding in regulatory compliance, minimizing latency, and enhancing security. The tutorial also discusses the setup requirements, such as enabling versioning and permissions. It highlights the replication process, including object metadata and deletion behaviors. Additionally, the video introduces same region replication, its use cases, and concludes with a transition to a practical demonstration in the AWS console.

What is the primary function of S3 Cross Region Replication?

• To enable synchronous copying of objects within the same region

• To allow manual copying of objects across different AWS accounts

• To replicate data across multiple devices within a single availability zone

• To automatically and asynchronously copy objects across buckets in different AWS regions

Which of the following is a benefit of using Cross Region Replication?

• It ensures data is always stored in the same region

• It helps in meeting regulatory compliance by storing data far away

• It allows for synchronous data replication

• It automatically encrypts all data during replication

How does Cross Region Replication help in preventing data deletion by a disgruntled employee?

• By changing the data ownership in the destination bucket

• By encrypting the data during replication

• By storing data in multiple availability zones

• By disabling access to the source bucket

What is a requirement for setting up Cross Region Replication?

• The destination bucket must have the same name as the source bucket

• The source bucket must be empty

• Versioning must be enabled on both source and destination buckets

• Both buckets must be in the same AWS region

Which objects are replicated when setting up Cross Region Replication?

• Only objects created before the replication configuration

• All objects, regardless of creation time

• Objects created after the replication configuration is added

• Only encrypted objects

What is a key use case for Same Region Replication?

• To automatically encrypt data during replication

• To replicate data across different AWS regions

• To aggregate logs from multiple sources into a single bucket

• To enable synchronous data replication

How does Same Region Replication differ from Cross Region Replication?

• SRR does not support log aggregation, while CRR does

• SRR is used for global resilience, while CRR is for local data access

• SRR requires manual configuration, while CRR is automatic

• SRR is for replicating within the same region, while CRR is for different regions
