Amazon-DEA-C01 Exam - Topic 3 Question 4 Discussion

Actual exam question for Amazon's Amazon-DEA-C01 exam

Question #: 4
Topic #: 3

A company wants to migrate data from an Amazon RDS for PostgreSQL DB instance in the eu-east-1 Region of an AWS account named Account_

AThe company will migrate the data to an Amazon Redshift cluster in the eu-west-1 Region of an AWS account named Account_B.
Which solution will give AWS Database Migration Service (AWS DMS) the ability to replicate data between two data stores?

ASet up an AWS DMS replication instance in Account_B in eu-west-1.

BSet up an AWS DMS replication instance in Account_B in eu-east-1.

CSet up an AWS DMS replication instance in a new AWS account in eu-west-1

DSet up an AWS DMS replication instance in Account_A in eu-east-1.

Show Suggested Answer

Suggested Answer: A, A

To migrate data from an Amazon RDS for PostgreSQL DB instance in the eu-east-1 Region (Account_A) to an Amazon Redshift cluster in the eu-west-1 Region (Account_B), AWS DMS needs a replication instance located in the target region (in this case, eu-west-1) to facilitate the data transfer between regions.

Option A: Set up an AWS DMS replication instance in Account_B in eu-west-1. Placing the DMS replication instance in the target account and region (Account_B in eu-west-1) is the most efficient solution. The replication instance can connect to the source RDS PostgreSQL in eu-east-1 and migrate the data to the Redshift cluster in eu-west-1. This setup ensures data is replicated across AWS accounts and regions.

Options B, C, and D place the replication instance in either the wrong account or region, which increases complexity without adding any benefit.

Why not just keep everything in one account? Seems simpler.

Nope, option B won't work since it's in the wrong region.

Wait, can you really set it up in a different account? Sounds risky.

You need the DMS instance in eu-west-1 for that!

I thought we had to set up the replication instance in the target region, which would point to option A again. But I could be mixing it up with another scenario.

I’m a bit confused about the regions. Wouldn't option D make sense since it's in the source region? But I feel like that might not be the best choice.

I remember practicing a question like this, and I think the replication instance should be in Account_B, which makes option A seem right.

I think we need the replication instance in the same region as the target, so maybe option A? But I'm not completely sure.

I'm pretty confident the answer is option B - set up the DMS replication instance in Account_B in the eu-east-1 Region. That way it can access both the source RDS instance and the target Redshift cluster.

Okay, let me think this through. The key is that the DMS instance needs to be able to access both the source RDS instance and the target Redshift cluster. So setting it up in the same account as the Redshift cluster, but a different Region, seems like the best approach.

Hmm, I'm a bit confused. The question mentions the source RDS instance is in the eu-east-1 Region, but the target Redshift cluster is in eu-west-1. Does that mean I need to set up the DMS instance in a different Region than the source or target?

This seems straightforward - I think the answer is to set up the DMS replication instance in the same account as the target Redshift cluster, which is Account_B in the eu-west-1 Region.

Option B? Really? Why would you set up the DMS instance in a different region than the target Redshift cluster? That's just asking for trouble.

Option A seems the most logical choice. Setting up the DMS replication instance in the same account and region as the target Redshift cluster makes the most sense.
