Question 23 of 75 | ← Chapter 2
Q173. A company has a critical application in which the data tier is deployed in a single AWS Region. The data tier uses an Amazon DynamoDB table and an Amazon Aurora MySQL DB cluster. The current Aurora MySQL engine version supports a global database. The application tier is already deployed in two Regions Company policy states that critical applications must have application tier components and data tier components deployed across two Regions. The RTO and RPO must be no more than a few minutes each. A solutions architect must recommend a solution to make the data tier compliant with company policy. Which combination of steps will meet these requirements?(Select TWO.)
- A. Add another Region to the Aurora MySQL DB cluster ✓
- B. Add another Region to each table in the Aurora MySQL DB cluster
- C. Set up scheduled cross-Region backups for the DynamoDB table and the Aurora MySQL DB cluster
- D. Convert the existing DynamoDB table to a global table by adding another Region to its configuration ✓
- E. Use Amazon Route 53 Application Recovery Controller to automate database backup and recovery to the secondary Region
Correct Answer: A. Add another Region to the Aurora MySQL DB cluster, D. Convert the existing DynamoDB table to a global table by adding another Region to its configuration
Explanation
To make the data tier compliant with company policy, it is necessary to deploy both the Amazon DynamoDB table and the Amazon Aurora MySQL DB cluster across at least two AWS Regions. Option A is correct since it involves adding another Region to the Aurora MySQL DB cluster, which ensures that the database is highly available and fault-tolerant. Option D is also correct since it involves converting the existing DynamoDB table to a global table by adding another Region to its configuration, which allows the table to replicate across multiple Regions. This ensures that the data is resilient in case of a disaster or outage in one Region. The other options either do not provide sufficient redundancy or are not relevant in this scenario.
