20+ practice questions focused on Design for New Solutions — one of the most tested topics on the AWS Certified Solutions Architect Professional SAP-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Design for New Solutions PracticeA company wants to migrate a monolithic application to AWS and redesign it using microservices. The application uses a MySQL database. The company wants to minimize operational overhead and enable each microservice to have its own database. Which AWS service should the company use to implement the database layer?
Explanation: Amazon RDS for MySQL is the correct choice because it provides a managed MySQL database service that minimizes operational overhead through automated backups, patching, and scaling. Each microservice can have its own RDS instance, enabling database-per-service isolation while offloading administrative tasks like replication and failover to AWS.
A company is designing a serverless application using AWS Lambda functions. The application processes events from an Amazon SQS queue. The company wants to ensure that the Lambda function can scale to handle a sudden increase in messages without losing any messages. The Lambda function must process each message at least once. Which configuration should the company use?
Explanation: Option A is correct because configuring the SQS queue as a Lambda event source with a reserved concurrency of 1000 ensures that Lambda can scale up to 1000 concurrent executions to handle a sudden burst of messages. The SQS event source uses long polling and synchronously invokes Lambda, which processes messages in batches and automatically deletes them from the queue only upon successful completion, guaranteeing at-least-once processing. Reserved concurrency prevents throttling and ensures that the function has sufficient capacity to scale without losing messages.
A company is designing a multi-account AWS environment using AWS Organizations. The company has several business units that each require their own VPC in shared accounts managed centrally. The company wants to enable VPC sharing to allow business units to create resources in shared subnets while maintaining network isolation. Which combination of steps should the company take to achieve this? (Choose TWO.)
Explanation: Option A is correct because AWS Resource Access Manager (RAM) allows you to share subnets from a centrally owned VPC with other AWS accounts within your AWS Organization. This enables business units to launch resources directly into the shared subnets while the VPC and its networking configuration remain managed centrally, ensuring network isolation through separate security groups and network ACLs.
A company is designing a disaster recovery solution for a critical application that runs on Amazon EC2 instances in a single AWS Region. The application uses an Amazon RDS for MySQL database. The recovery time objective (RTO) is 1 hour and the recovery point objective (RPO) is 15 minutes. Which combination of steps should the company take to meet these requirements? (Choose THREE.)
Explanation: Option A is correct because Route 53 health checks can monitor the primary application's endpoint, and DNS failover to a secondary Region enables automatic traffic redirection within minutes, aligning with the 1-hour RTO. This approach provides a simple, stateless failover mechanism without requiring complex routing changes.
A company is designing a serverless data processing pipeline using AWS Step Functions, AWS Lambda, and Amazon DynamoDB. The pipeline must process incoming JSON records from an Amazon Kinesis Data Stream. Each record must be processed exactly once and in order. The company expects a throughput of up to 1,000 records per second. Which combination of services and configurations should the company use to meet these requirements? (Choose TWO.)
Explanation: Option C is correct because with a throughput of 1,000 records per second, a Kinesis Data Stream with 10 shards provides the necessary capacity (each shard supports up to 1,000 records/second for ingestion and 2 MB/s for reads). This shard count ensures the stream can handle the peak load without throttling, while maintaining the ordering guarantee within each shard.
