To configure replication of a DynamoDB table to another AWS Region for disaster recovery, you should use DynamoDB Global Tables. Global Tables use DynamoDB Streams to replicate changes across multiple regions.

Enable DynamoDB Streams:

Navigate to the DynamoDB console.

Select your table and enable DynamoDB Streams.

Add a Global Table Region:

With Streams enabled, go to the Global Tables tab.

Add a new region to the table, specifying the region where you want to replicate the data.

Automatic Replication:

DynamoDB will handle the replication of data across regions automatically, ensuring data consistency and high availability.

To serve static websites using S3 and Route 53, AWS requires the bucket name to match the custom domain name (e.g., not just a random bucket like example-website-hosting-bucket.

From the Amazon S3 Static Website Hosting Guide:

To use Amazon Route 53 to route domain traffic to an S3 bucket that is configured as a static website, the bucket name must match the name of the domain or subdomain.

This means:

To host you must create an S3 bucket named

Then configure static website hosting on that bucket

In Route 53, you can then create an alias record pointing to the S3 website endpoint

❌ Why the other options are incorrect:

A. ARNs are not valid alias targets in Route 53.

B. ARN changes do not affect Route 53; also, you cannot rename an S3 bucket via ARN changes.

C. Access Points do not support static website hosting. They are for programmatic access via APIs.

AWS EBS snapshots are incremental, meaning that after the initial full snapshot, only the blocks that have changed since the last snapshot are saved. Here’s how the storage adds up based on your scenario:

First Snapshot: Captures all 10 GiB of data.

Second Snapshot: Only 4 GiB have changed, so only these changed blocks are stored.

Third Snapshot: An additional 2 GiB of data are added, making only these new 2 GiB stored.

Thus, the total storage required is 10 GiB (initial snapshot) + 4 GiB (second snapshot) + 2 GiB (third snapshot) = 16 GiB.
