Exam AWS Certified Solutions Architect - Professional topic 1 question 729 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 729
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company that tracks medical devices in hospitals wants to migrate its existing storage solution to the AWS Cloud. The company equips all of its devices with sensors that collect location and usage information. This sensor data is sent in unpredictable patterns with large spikes. The data is stored in a MySQL database running on premises at each hospital. The company wants the cloud storage solution to scale with usage.
The company's analytics team uses the sensor data to calculate usage by device type and hospital. The team needs to keep analysis tools running locally while fetching data from the cloud. The team also needs to use existing Java application and SQL queries with as few changes as possible.
How should a solutions architect meet these requirements while ensuring the sensor data is secure?

  • A. Store the data in an Amazon Aurora Serverless database. Serve the data through a Network Load Balancer (NLB). Authenticate users using the NLB with credentials stored in AWS Secrets Manager.
  • B. Store the data in an Amazon S3 bucket. Serve the data through Amazon QuickSight using an IAM user authorized with AWS Identity and Access Management (IAM) with the S3 bucket as the data source.
  • C. Store the data in an Amazon Aurora Serverless database. Serve the data through the Aurora Data API using an IAM user authorized with AWS Identity and Access Management (IAM) and the AWS Secrets Manager ARN.
  • D. Store the data in an Amazon S3 bucket. Serve the data through Amazon Athena using AWS PrivateLink to secure the data in transit.

Going with C. because it works with the app still running on-prem. You will still need a few code changes but the question allows that. D. would sound plausible but PrivateLink is for VPC only

Existing MySQL database can't be easy to serve from S3 (object storage) that ruled out S3 option and NLB is also not good option that leaves only C

I wonder how option C satisfies the statement "use existing Java application and SQL queries with as few changes as possible"? btw Aurora Serverless has an "invisible" NLB in front

B&D - no, as SQL queries are desired.. A - no, unless anyone can show me how this works: "Authenticate users using the NLB with credentials stored in AWS Secrets Manager."

CCC --- The data is currently stored in a MySQL database running on-prem. Storing MySQL data in S3 doesn't sound good so B & D are out. Aurora Data API "enables the SQL HTTP endpoint, a connectionless Web Service API for running SQL queries against this database. When the SQL HTTP endpoint is enabled, you can also query your database from inside the RDS console (these features are free to use)."

My answer is D. The team also needs to use existing Java application and SQL queries with as few changes as possible. THere is a requirement to be able to execute sql queries. Athena provides the way!!
