Question 48

A company wants to design a microservices architecture for an application. Each microservice must perform operations that can be completed within 30 seconds.

The microservices need to expose RESTful APIs and must automatically scale in response to varying loads. The APIs must also provide client access control and rate limiting to maintain equitable usage and service availability.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Use Amazon Elastic Container Service (Amazon ECS) on Amazon EC2 to host each microservice. Use Amazon API Gateway to manage the RESTful API requests.

Deploy each microservice as a set of AWS Lambda functions. Use Amazon API Gateway to manage the RESTful API requests.

Host each microservice on Amazon EC2 instances in Auto Scaling groups behind an Elastic Load Balancing (ELB) load balancer. Use the ELB to manage the RESTful API requests.

Deploy each microservice on Amazon Elastic Beanstalk. Use Amazon CloudFront to manage the RESTful API requests.

Passed the exam. questions are valid. The customer support is top-notch. They were quick to respond to any questions I had and provided me with all the information I needed.

Cillian Oct 9, 2025

That's a big plus. I've used other dump providers in the past and the customer support was often lacking.

Options:

Server-side encryption with customer-provided keys (SSE-C)

Server-side encryption with Amazon S3 managed keys (SSE-S3)

Server-side encryption with AWS KMS keys (SSE-KMS) with manual rotation

Server-side encryption with AWS KMS keys (SSE-KMS) with automatic rotation

Question 50

A company needs to run its external website on Amazon EC2 instances and on-premises virtualized servers. The AWS environment has a 1 GB AWS Direct Connect connection to the data center. The application has IP addresses that will not change. The on-premises and AWS servers are able to restart themselves while maintaining the same IP address if a failure occurs. Some website users have to add their vendors to an allow list, so the solution must have a fixed IP address. The company needs a solution with the lowest operational overhead to handle this split traffic.

What should a solutions architect do to meet these requirements?

Options:

Deploy an Amazon Route 53 Resolver with rules pointing to the on-premises and AWS IP addresses.

Deploy a Network Load Balancer on AWS. Create target groups for the on-premises and AWS IP addresses.

Deploy an Application Load Balancer on AWS. Register the on-premises and AWS IP addresses with the target group.

Deploy Amazon API Gateway to direct traffic to the on-premises and AWS IP addresses based on the header of the request.

Question 51

A company has a web application that uses Amazon API Gateway to route HTTPS requests to AWS Lambda functions. The application uses an Amazon Aurora MySQL database for its data storage. The application has experienced unpredictable surges in traffic that overwhelm the database with too many connection requests. The company wants to implement a scalable solution that is more resilient to database failures.

Which solution will meet these requirements MOST cost-effectively?

Options:

Create an Amazon RDS proxy for the database. Replace the database endpoint with the proxy endpoint in the Lambda functions.

Migrate the database to Amazon DynamoDB tables by using AWS Database Migration Service (AWS DMS).

Review the existing connections. Call MySQL queries to end any connections in the sleep state.

Increase the instance class of the database with more memory. Set a larger value for the max_connections parameter.
