Exam AWS Certified Solutions Architect - Professional topic 1 question 821 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 821
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A hedge fund company is developing a new web application to handle trades. Traders around the world will use the application. The application will handle hundreds of thousands of transactions, especially during overlapping work hours between Europe and the United States.
According to the company's disaster recovery plan, the data that is generated must be replicated to a second AWS Region. Each transaction item will be less than
100 KB in size. The company wants to simplify the CI/CD pipeline as much as possible.
Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

  • A. Deploy the application in multiple Regions. Use Amazon Route 53 latency-based routing to route users to the nearest deployment.
  • B. Provision an Amazon Aurora global database to persist data. Use Amazon ElastiCache to improve response time.
  • C. Provision an Amazon CloudFront domain with the website as an origin. Restrict access to geographies where the usage is expected.
  • D. Provision an Amazon DynamoDB global table. Use DynamoDB Accelerator (DAX) to improve response time.
  • E. Provision an Amazon Aurora multi-master cluster to persist data. Use Amazon ElastiCache to improve response time.

I agree with A and D B) Answer is possible, but the transaction size of < 100KB sounds like DynamoDB to me C) Doesn't help in this scenario E) Multi-Master means data is only copied to one region

The following limitations currently apply to the AWS and Aurora features that you can use with multi-master clusters: Currently, all DB instances in a multi-master cluster must be in the same AWS Region. It's required that data should be copied to second region, So E is wrong. I agree with A and D. https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-multi-master.html

You have to replicate DB to a different region. So Answer E shouldn't be answer because multi master cluster must be in same region.
