201.A healthcare provider is deploying a new patient management system that stores highly sensitive patient health information (PHI). The system must comply with HIPAA regulations, ensuring data encryption at rest and in transit, strict access controls, and comprehensive auditing. The application will be hosted on Amazon EC2 instances within a private subnet, accessing an Amazon S3 bucket for medical images and an Amazon RDS for PostgreSQL database for patient records. Which configuration elements are ESSENTIAL to ensure HIPAA compliance for these services?Design for New Solutions
202.A global online gaming company is launching a new massively multiplayer online (MMO) game. The game backend requires a database that can handle extremely high read and write throughput (millions of transactions per second) with very low latency (single-digit milliseconds), support a flexible data model for player profiles and game state, and provide global replication for players worldwide. Data consistency for critical game state is paramount. Which AWS database service is the MOST appropriate choice?Design for New Solutions
203.A global manufacturing company needs to implement a new data platform to collect, process, and analyze sensor data from its machinery across multiple factories worldwide. The data volume is expected to be in the tens of terabytes daily, requiring real-time ingestion, transformation, and storage for both immediate operational insights and long-term historical analysis. The solution must support SQL-based querying for analysts and provide a cost-effective storage solution for cold data. What is the MOST appropriate data platform architecture?Design for New Solutions
204.A global financial institution is expanding its operations into new regions and needs to establish a secure and compliant landing zone on AWS for all new accounts. The solution must enforce security best practices, provide centralized logging and monitoring, and automate account provisioning across multiple AWS accounts and regions. Which AWS service provides the most comprehensive solution for these requirements?Design for New Solutions
205.A research institution is building a new data platform to ingest genomic sequencing data, which involves petabytes of large, unstructured files (e.g., FASTQ, BAM files). This data needs to be stored cost-effectively, accessed frequently for high-performance computing (HPC) analysis with low latency, and capable of being shared securely with collaborators globally. The solution must also support data lifecycle management. Which storage solution should the architect recommend?Design for New Solutions
206.A research institution is building a new data platform to ingest genomic sequencing data, which consists of extremely large files (terabytes per file) and requires high-throughput, low-latency access for parallel processing by high-performance computing (HPC) clusters. The data will be accessed by hundreds of compute nodes concurrently. The solution must provide POSIX-compliant file system access. Which AWS storage solution is most suitable for this use case?Design for New Solutions
207.A financial analytics firm is building a new application that processes highly sensitive customer financial data. The application will leverage containerized microservices orchestrated by Amazon ECS. The firm has a strict security posture requiring that all data, including temporary processing data, never leaves the firm's private network boundaries, even when interacting with AWS services. Data must be encrypted at rest and in transit, and access to all services must be restricted to specific VPC endpoints. Which networking and security configuration should be implemented?Design for New Solutions
208.A financial institution is building a new data platform to ingest, process, and analyze vast amounts of financial transaction data for regulatory compliance and fraud detection. The data arrives continuously and must be processed in real-time, with results available for query within seconds. The solution needs to handle petabytes of data, support complex SQL queries, and integrate with existing business intelligence (BI) tools. Which AWS services should be used to design this platform?Design for New Solutions
209.A software-as-a-service (SaaS) provider is building a new multi-tenant application that requires strong tenant isolation, both logically and physically, to meet regulatory compliance requirements. Each tenant's data must be completely separate from other tenants, and their application resources should not be shared at the EC2 instance level. The solution needs to be highly scalable, cost-efficient, and minimize operational overhead. Which multi-tenancy model and corresponding AWS services would best achieve these goals?Design for New Solutions
210.A global online gaming company is launching a new massively multiplayer online (MMO) game. The game backend needs to store player profiles, game state, and leaderboard data. This data must support millions of concurrent users, provide extremely low-latency access (single-digit milliseconds), and scale globally across multiple AWS regions for high availability and disaster recovery. Data consistency for critical game state is crucial. Which AWS database solution is the most appropriate for this scenario?Design for New Solutions
211.A global online gaming company is launching a new massively multiplayer online (MMO) game. The game requires a highly scalable, low-latency database to store player profiles, game state, and leaderboards. The database must handle millions of concurrent read/write operations per second, provide strong consistency for critical game data (e.g., inventory), and offer eventual consistency for less critical data (e.g., chat logs). It also needs to support flexible schema changes as game features evolve. Which AWS database service is the most appropriate choice?Design for New Solutions
212.A software-as-a-service (SaaS) provider is building a new multi-tenant application where each tenant requires strong data isolation and dedicated resources for their database. The application needs to support a wide range of tenant sizes, from small businesses to large enterprises, without over-provisioning resources for smaller tenants or requiring manual scaling for larger ones. The database must be highly available and fault-tolerant. Which database strategy should the architect recommend?Design for New Solutions
213.A global e-commerce company is launching a new product catalog service. The service needs to handle millions of requests per second, with sub-10ms latency for read operations, and must be highly available and globally consistent across multiple AWS Regions. The data model is flexible and evolving, with frequent schema changes expected. Which database service is most appropriate for this scenario?Design for New Solutions
214.A research institution is building a new data platform to ingest genomic sequencing data, which consists of extremely large files (up to several terabytes each) that need to be accessed by high-performance computing (HPC) clusters for intensive analysis. The storage solution must provide very high throughput and low latency for concurrent reads from multiple compute nodes, support petabyte-scale storage, and be cost-effective for long-term retention. Which AWS storage service should be recommended?Design for New Solutions
