Amazon SAA-C03 Exam - Topic 11 Question 4 Discussion

Actual exam question for Amazon's SAA-C03 exam

Question #: 4
Topic #: 11

An ecommerce company has an order-processing application that uses Amazon API Gateway and an AWS Lambda function. The application stores data in an Amazon Aurora PostgreSQL database. During a recent sales event, a sudden surge in customer orders occurred. Some customers experienced timeouts and the application did not process the orders of those customers A solutions architect determined that the CPU utilization and memory utilization were high on the database because of a large number of open connections The solutions architect needs to prevent the timeout errors while making the least possible changes to the application.

Which solution will meet these requirements?

AConfigure provisioned concurrency for the Lambda function Modify the database to be a global database in multiple AWS Regions

BUse Amazon RDS Proxy to create a proxy for the database Modify the Lambda function to use the RDS Proxy endpoint instead of the database endpoint

CCreate a read replica for the database in a different AWS Region Use query string parameters in API Gateway to route traffic to the read replica

DMigrate the data from Aurora PostgreSQL to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS| Modify the Lambda function to use the OynamoDB table

A global database sounds cool, but is it really necessary?

I thought read replicas were the solution, but maybe not?

Wait, why would you migrate to DynamoDB? Seems like overkill.

Totally agree, RDS Proxy is a game changer for scaling!

B is the best option, RDS Proxy can handle connections better.

I feel like option A is a bit off; provisioned concurrency is more about Lambda performance, not directly addressing database connection limits.

I practiced a similar question where using RDS Proxy was the right answer to handle connection issues. It makes sense to use it here too.

I'm not entirely sure, but I think option C might not be the best choice since it involves creating a read replica in a different region, which could add latency.

I remember studying about RDS Proxy and how it can help manage database connections, which seems relevant here.

I'm feeling pretty confident about this one. I think Option D is the way to go - it seems to directly address the requirement of allowing iexplore.exe to run only from the \Program Files\Internet Explorer\ directory.

Hmm, this is a tricky one. I'll need to think carefully about how transactions and concurrency control work in this scenario.

I remember practicing a similar question, and I believe the EPG and application profile might both be options.
