Replication Configuration for Amazon S3 Bucket

Prev Question

Question

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?

A. B. C. D.

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.

When configuring replication for an Amazon S3 bucket, there are a few factors that need to be considered to ensure that the replicated data is consistent and complies with security requirements.

First, it is important to understand that Amazon S3 replication allows the replication of objects between buckets located in different regions. This means that data can be replicated in a different region for security and disaster recovery purposes.

Next, when configuring rules for replication, there are two types of filters that can be used: object tags and object key prefixes.

Object tags are metadata assigned to objects that provide additional information about the objects. Object key prefixes, on the other hand, are a string of characters that precede the object's key name in the bucket.

Now, let's take a look at the options provided:

A. Can add a single rule having filters matching objects based upon only object tags.

This option implies that the replication configuration will only consider object tags when filtering objects for replication. This approach may not be sufficient if there are specific object key prefixes that need to be replicated.

B. Can add multiple rules having filters matching objects based upon object tags or object key prefixes.

This option allows for multiple rules to be created, which can include filters based on both object tags and object key prefixes. This approach is more flexible and can provide more granular control over the replication process.

C. Can add a single rule having filters matching objects based upon object tags or object key prefixes.

This option allows for a single rule to be created that can include filters based on both object tags and object key prefixes. While this option provides more flexibility than option A, it may not provide the level of granularity needed for certain replication scenarios.

D. Can add multiple rules having filters matching objects based upon only object tags.

This option implies that the replication configuration will only consider object tags when filtering objects for replication, and also allows for multiple rules to be created. Similar to option A, this approach may not be sufficient if there are specific object key prefixes that need to be replicated.

In conclusion, options B and C are the most appropriate for creating rules for replication configuration as they allow for both object tags and object key prefixes to be used for filtering objects. Option B provides more flexibility in terms of creating multiple rules, while option C provides a simpler approach with a single rule.
