Amazon Exam DBS-C01 Topic 1 Question 89 Discussion

Actual exam question for Amazon's DBS-C01 exam

Question #: 89
Topic #: 1

A retail company is about to migrate its online and mobile store to AWS. The company's CEO has strategic plans to grow the brand globally. A Database Specialist has been challenged to provide predictable read and write database performance with minimal operational overhead.

What should the Database Specialist do to meet these requirements?

AUse Amazon DynamoDB global tables to synchronize transactions

BUse Amazon EMR to copy the orders table data across Regions

CUse Amazon Aurora Global Database to synchronize all transactions

DUse Amazon DynamoDB Streams to replicate all DynamoDB transactions and sync them

Show Suggested Answer

Suggested Answer: B

According to the Amazon Redshift documentation1, you can enable database encryption for your clusters to help protect data at rest. You can use either AWS Key Management Service (AWS KMS) or a hardware security module (HSM) to manage the top-level encryption keys in this hierarchy. The process that Amazon Redshift uses for encryption differs depending on how you manage keys.

To copy encrypted snapshots across Regions, you need to create a snapshot copy grant in the destination Region and specify a CMK in that Region. You also need to configure cross-Region snapshots in the source Region and provide the destination Region, the snapshot copy grant, and retention periods for the snapshots. This way, you can automate the process of backing up the cluster data in compliance with the corporate policies.

That's a good point. Maybe option C is the way to go after all.

That's true, but configuring cross-Region snapshots with S3 replication in option C provides redundancy.

But wouldn't copying the KMS key to the destination Region be more secure?

I think option C is the most secure option as it involves replicating the snapshots with specified KMS key IDs.

But with option C, we can use EventBridge to automate the process with Lambda function.

I prefer option A. It's more straightforward to copy the key and use AWS Glue job.

Yeah, I like the elegance of option C as well. Leveraging existing AWS services like Eventbridge, Lambda, and S3 replication makes a lot of sense here.

I'm leaning towards option C. Using EventBridge and Lambda to automate the snapshot process, along with S3 Cross-Region Replication, seems like a robust and comprehensive solution.

I agree. The key is to properly set up the KMS keys and configure the cross-region snapshot replication. It's a good thing they're giving us multiple options to consider.

You know, I'm a little concerned about the complexity of some of these solutions. Wouldn't it be simpler to just backup to an S3 bucket and let S3 handle the encryption and replication?

That's a good point. Option D does seem more straightforward in terms of the key management. But I'm not sure if that fully meets the requirement of using 'customer-managed' keys in both regions.

I think option B is the way to go. Creating a new KMS key in the destination Region and configuring cross-Region snapshots seems like the most straightforward approach.

Oh man, I hope they don't ask us to explain the intricacies of AWS KMS and cross-Region replication. That stuff always makes my head spin.

Option D could work too, as long as the CMK is properly configured.
