A banking institute is storing all its critical data in an Amazon S3 bucket in the us-west region. For security compliance, these data need to be replicated in multiple regions. You have been assigned the task of creating a replication configuration for the source bucket. Which of the following should be considered while creating rules for replication configuration?

Answer options:

A.Can add a single rule having filters matching objects based upon only object tags.
B.Can add multiple rules having filters matching objects based upon object tags or object key prefixes.
C.Can add a single rule having filters matching objects based upon object tags or object key prefixes.
D.Can add multiple rules having filters matching objects based upon only object tags.

Correct Answer – B
For enabling replication on the Amazon S3 bucket, replication configuration is required to be added. While creating replication configuration, multiple rules can be added based upon the subset of objects to be matched. Filter for these rules can be based upon matching objects tag or object key prefixes or any combination of both.
Option A & C are incorrect as multiple rules can be added in replication configuration based upon subsets of objects.
Option D is incorrect as filters can be configured to match object tags and object key prefixes or a combination of both.
