Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 339
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is migrating a legacy application from an on-premises data center to AWS. The application consists of a single application server and a Microsoft SQL Server database server. Each server is deployed on a VMware VM that consumes 500 TB of data across multiple attached volumes.

The company has established a 10 Gbps AWS Direct Connect connection from the closest AWS Region to its on-premises data center. The Direct Connect connection is not currently in use by other services.

Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime? (Choose two.)

  • A. Use an AWS Server Migration Service (AWS SMS) replication job to migrate the database server VM to AWS.
  • B. Use VM Import/Export to import the application server VM.
  • C. Export the VM images to an AWS Snowball Edge Storage Optimized device.
  • D. Use an AWS Server Migration Service (AWS SMS) replication job to migrate the application server VM to AWS.
  • E. Use an AWS Database Migration Service (AWS DMS) replication instance to migrate the database to an Amazon RDS DB instance.

It does not actually say that the DB itself is 500TB, but that its the total size of storage for both VMs. I really do not like this question. The information provided leaves a lot of room for assumptions.

FYI: Server Migration Service (AWS SMS) has been discontinued. AWS now recommends the AWS Application Migration Service as the primary migration service.

Answer is AD. This is a crazy question with lot of ambiguity, the question prepared just based of one blog with no clear information :) Reference: https://aws.amazon.com/blogs/compute/learn-about-hourly-replication-in-server-migration-service-and-the-ability-to-migrate-large-data-volumes/

3 limit here: RDS volume - 16TB DMS - 30TB EBS - 64TB none of them matching the 500TB of size. so only possible here: write forgot the size limit but made the question only focus on comparision between DX and Snowball. Or, the 500TB size of file is no db or not a single file which can be split to different volumes. And in either case above, DE would be the answer that author is looking for, Simple as Do you know what DMS is.

Option ACE. You need to create a transit gateway, set up at routing table for communication route rules and finally, create a transit gateway attachment to a VPN .

That is temporary storage as a staging area until it replicates to the target server. You can replicate more than 30TB to a target VM using DMS. "The 30,000-GB quota for storage applies to all your AWS DMS replication instances in a given AWS Region. This storage is used to cache changes if a target can't keep up with a source, and for storing log information."

https://www.amazonaws.cn/en/server-migration-service/faqs/ Q: What is the difference between EC2 VM Import and Amazon Server Migration Service? Amazon Server Migration Service is a significant enhancement of EC2 VM Import. The Amazon Server Migration Service provides automated, live incremental server replication and Amazon Web Services Console support. For customers using EC2 VM Import for migration, we recommend using Amazon Server Migration Service.

Answer: DE Both AWS SMS and AWS DMS offer continuous replication, allowing the application and database to be kept in sync with their AWS counterparts during the migration process. This enables a switchover with minimal downtime.
