Question
A developer can use Amazon S3 to configure Cross-Region Replication of objects. What is one benefit of enabling Cross-Region Replication?
A. Minimize administrative time by giving multiple administrators object access
B. Minimize latency by maintaining object copies in AWS Regions that are geographically closer to their users
C. Minimize tracking requirements by having multiple copies of each object
D. Minimize the number of Amazon EC2 instances needed to access their objects
Answer
B. Minimize latency by maintaining object copies in AWS Regions that are geographically closer to their users
Explanation
Cross-Region Replication puts copies of objects geographically closer to your users, which minimizes latency. It can also help you increase operational efficiency and be better equipped for disaster recovery.
The correct answer is B. Minimize latency by maintaining object copies in AWS Regions that are geographically closer to their users.
Amazon S3 Cross-Region Replication (CRR) automatically replicates objects across buckets in different AWS Regions. One key benefit of this is reducing latency for users accessing the objects.
By replicating objects to an AWS Region geographically closer to the users requesting them, the data has a shorter distance to travel over the network, resulting in faster retrieval times and a better user experience. For example, if a company primarily serves users in both North America and Europe, keeping replicated copies of objects in both an East Coast US region and an EU region would allow users from each area to access the objects more quickly compared to if the objects were only stored in one region.
The other options are incorrect:
A) CRR itself doesn’t give multiple administrators object access. While CRR could be part of a multi-region strategy, administrator access would be configured separately through IAM policies, bucket policies, etc.
C) CRR actually increases tracking requirements, as the replication status of objects must now be monitored.
D) The number of EC2 instances accessing S3 objects is independent of CRR. CRR neither increases nor decreases the number of instances required.
In summary, a key benefit of enabling S3 Cross-Region Replication is minimizing latency by storing object copies closer to users in different geographic areas. This improves performance for globally distributed users accessing the replicated data.
