Practice test
  1. 201.A global gaming company is developing a new multiplayer online game. The game server architecture needs to provide extremely low latency for players worldwide, with consistent performance regardless of their geographical location. The solution must also offer automatic routing to the nearest healthy game server in case of regional outages. Which AWS service is best suited to meet these requirements for game traffic?Design High-Performing Architectures
  2. 202.A global SaaS company is building a new microservices platform on AWS. They need a highly scalable, fully managed service to send notifications to various endpoints (e.g., email, SMS, other microservices) when certain events occur within their system. The service must support fan-out messaging to multiple subscribers simultaneously. Which AWS service should they choose?Design Resilient Architectures
  3. 203.A global real estate company hosts its property listing website on AWS. The website experiences inconsistent user experience and high latency for users located far from the primary `us-east-1` region. They want to improve performance by routing user traffic to the nearest healthy application endpoint, regardless of where the application is hosted globally. Which AWS service should they use?Design Resilient Architectures
  4. 204.An online media streaming company needs to store petabytes of video content that will be accessed frequently by millions of users worldwide. The content requires high availability, extreme durability, and low latency for streaming. Additionally, the company wants to optimize content delivery to global users by caching frequently accessed videos at edge locations. Which combination of AWS services will provide the most high-performing and scalable solution?Design High-Performing Architectures
  5. 205.A global e-commerce company experiences highly variable traffic patterns, with significant spikes during promotional events and seasonal sales. The company's primary database is a relational database hosted on Amazon EC2, which struggles to scale efficiently during peak loads. They need a database solution that can automatically scale capacity up and down to meet demand without manual intervention, while maintaining high performance and availability. Which AWS database service is most suitable for this requirement?Design High-Performing Architectures
  6. 206.A financial services company is developing a new real-time fraud detection system. The system needs to ingest millions of transaction events per second, process them with extremely low latency, and store them for immediate analysis by machine learning models. The data must be ordered, durable, and highly available. Which AWS service is best suited for ingesting and temporarily storing this high-throughput, low-latency data stream?Design High-Performing Architectures
  7. 207.A company is building a new application that will process real-time sensor data from IoT devices. The data needs to be ingested, processed, and stored for analysis. The application must be highly scalable and fault-tolerant to handle millions of data points per second. Which AWS service is best suited for ingesting this high-volume, real-time data?Design Resilient Architectures
  8. 208.A global SaaS provider hosts its primary application in the `us-east-1` region and serves customers worldwide. To improve resilience and reduce latency for users in Europe and Asia, they want to establish a disaster recovery strategy that provides a recovery time objective (RTO) of minutes and a recovery point objective (RPO) of seconds. They need to replicate their Amazon Aurora MySQL-compatible database to a secondary region. Which Aurora feature is best suited for this requirement?Design Resilient Architectures
  9. 209.A global e-commerce company operates a mission-critical application with a multi-tier architecture in the `us-east-1` region. They need to implement a disaster recovery (DR) strategy that minimizes costs while providing a recovery time objective (RTO) of less than 4 hours and a recovery point objective (RPO) of less than 1 hour. This strategy should involve having a minimal, but ready-to-scale, environment in a secondary region. Which disaster recovery strategy should they choose?Design Resilient Architectures
  10. 210.A large enterprise has hundreds of legacy applications running on-premises that need to connect to new microservices hosted in various AWS VPCs. The enterprise requires secure, high-bandwidth, and low-latency connectivity between its on-premises data centers and AWS, while also simplifying network management and ensuring consistent routing across all connections. Which combination of AWS networking services would best meet these requirements?Design High-Performing Architectures
  11. 211.A global e-commerce company experiences unpredictable traffic spikes during flash sales and holiday seasons. They need a solution that automatically scales their web application to handle these fluctuations while minimizing operational overhead. The solution should also distribute incoming traffic across multiple EC2 instances. Which combination of AWS services should they use?Design Resilient Architectures
