Amazon Exam DBS-C01 Topic 7 Question 87 Discussion

Actual exam question for Amazon's DBS-C01 exam

Question #: 87
Topic #: 7

A company is moving its fraud detection application from on premises to the AWS Cloud and is using Amazon Neptune for data storage. The company has set up a 1 Gbps AWS Direct Connect connection to migrate 25 TB of fraud detection data from the on-premises data center to a Neptune DB instance. The company already has an Amazon S3 bucket and an S3 VPC endpoint, and 80% of the company's network bandwidth is available.

How should the company perform this data load?

AUse an AWS SDK with a multipart upload to transfer the data from on premises to the S3 bucket. Use the Copy command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.

BUse AWS Database Migration Service (AWS DMS) to transfer the data from on premises to the S3 bucket. Use the Loader command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.

CUse AWS DataSync to transfer the data from on premises to the S3 bucket. Use the Loader command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.

DUse the AWS CLI to transfer the data from on premises to the S3 bucket. Use the Copy command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.

Show Suggested Answer

Suggested Answer: A

General Purpose SSD storage is a cost-effective storage option that is ideal for a broad range of workloads running on medium-sized DB instances1.General Purpose storage is best suited for development and testing environments1.Since the database is primarily used for nightly batch processing, it does not require high I/O performance or low latency that Provisioned IOPS storage offers12.Magnetic storage and Throughput Optimized HDD are not recommended for new storage needs, and they have lower storage limits than General Purpose SSD and Provisioned IOPS SSD1. Therefore, General Purpose SSD storage meets the requirements most cost-effectively.

That's a good point, Throughput Optimized HDD could provide the necessary performance at a lower cost.

I think Throughput Optimized hard disk drives (HDD) could also be a good option for this type of workload.

But wouldn't Provisioned IOPS storage be more expensive compared to General Purpose SSD storage?

I disagree, I think Provisioned IOPS storage would be more suitable for the nightly batch processing.

I think we should choose the most cost-effective RDS storage option for migrating the database.

Because it has lower cost compared to SSD and still provides decent performance for batch processing.

Why do you think Magnetic storage would be better?

That's a good point. It might be worth the extra cost for better performance.

Definitely, the Throughput Optimized HDD seems like the way to go. It should provide enough performance for the batch processing without breaking the bank. Although, I do wonder how much Amazon charges for their 'Bulk Discount' on hard drives - maybe we should look into that.

Yeah, I agree. Provisioned IOPS is probably too much for a nightly batch processing workload. I'd be leaning towards the Throughput Optimized HDD option as the most cost-effective choice here.

You're right, the performance needs are key here. I'm thinking either Provisioned IOPS or Throughput Optimized HDD could work, but Provisioned IOPS might be overkill and more expensive than necessary.

Hmm, this is a tricky one. The database is 4 TB and primarily used for nightly batch processing, so I'd say we need to look at the performance requirements more than just the storage size.
