An architect is designing a new serverless architecture for a web application. The frontend is a Single Page Application (SPA) written in React. The backend requires a GraphQL API. Which THREE AWS services should be used? (Select THREE)

A company is migrating a legacy application that relies on multicast networking. AWS VPCs do not natively support multicast. Which THREE approaches can be used to support this workload on AWS? (Select THREE)

An organization is migrating a complex monolithic application to AWS. They have decided to use the Strangler Fig pattern to gradually extract microservices. Which FOUR AWS services are typically used to implement this pattern? (Select FOUR)

A company is migrating a legacy application to AWS. The application requires a shared file system that supports the SMB protocol. The application will run on a fleet of Amazon EC2 Windows instances across multiple Availability Zones. The file system must be highly available and integrate with the company's on-premises Active Directory. Which combination of steps will meet these requirements? (Select TWO)

A company has a monolithic legacy application running on-premises. They want to migrate to AWS and modernize the application into microservices. The business cannot tolerate any downtime during the migration, and the modernization must happen gradually to minimize risk. Which combination of architectural patterns and services should the architect use? (Select TWO)

An enterprise is modernizing a legacy application that relies on a massive, monolithic relational database. They want to break the database apart into purpose-built databases. The application requires a highly connected social graph to recommend friends, and a high-throughput key-value store for session management. Which combination of AWS databases should they migrate to? (Select TWO)

An enterprise is migrating its on-premises data center to AWS. They have a legacy mainframe application that cannot be migrated. However, the new microservices built on AWS need to query data from the mainframe with sub-millisecond latency. The mainframe and AWS are connected via AWS Direct Connect. How can the architect meet the latency requirement?

A company is migrating a legacy application that uses a proprietary UDP-based protocol. The application will be hosted on EC2 instances across multiple Availability Zones. The company needs a load balancer to distribute the UDP traffic. Which AWS load balancer should they use?

An enterprise is migrating a legacy monolithic application to AWS. The application uses a proprietary file system and requires sub-millisecond latency to shared storage. The application runs on Windows Server and cannot be refactored. The architecture must support high availability across multiple Availability Zones. Which storage solution meets these requirements?

A company is migrating a critical MySQL database to Amazon Aurora MySQL. The database handles high-volume financial transactions. The architecture must ensure zero data loss (RPO = 0) in the event of an Availability Zone failure, and minimal downtime (RTO < 1 minute). The application must securely authenticate to the database without hardcoding credentials. Which combination of features should be used? (Select TWO)

A company is migrating a large-scale IoT application to AWS. Millions of devices send telemetry data via MQTT. The data needs to be ingested, filtered, and routed to Amazon S3 for long-term storage and to Amazon DynamoDB for real-time dashboarding. The architecture must be fully managed and scale automatically to handle millions of concurrent connections. Which AWS service should act as the primary entry point for the devices?

An architect is designing a new serverless architecture to replace a legacy on-premises order processing system. The new system must receive orders via an API, validate them, save them to a database, and notify a downstream fulfillment system. Which THREE AWS services should be used to build this modern architecture? (Select THREE)

A company is refactoring a monolithic application into microservices. They want to use an event-driven architecture where microservices communicate asynchronously. They need a service that can filter and route events to multiple targets based on the event content. Which THREE configurations are required? (Select THREE)

An architect is designing a data lake architecture on AWS. Data will be ingested from various sources, transformed, and queried using standard SQL. The solution must be fully managed and serverless. Which THREE services should be included in this architecture? (Select THREE)

A company is migrating a legacy application to AWS. The application requires a shared file system that supports the POSIX permissions model and can be accessed concurrently by hundreds of EC2 Linux instances across multiple Availability Zones. Which THREE actions should the architect take? (Select THREE)

An architect is designing a multi-region active-active architecture for a critical API. The API is backed by DynamoDB. Traffic must be routed to the region closest to the user, but if a region fails, traffic must automatically failover to the healthy region. Which THREE configurations are required? (Select THREE)

An organization is migrating its on-premises data center to AWS. They have a legacy application hardcoded to use specific IP addresses. The application must be migrated to AWS without changing these IP addresses. The on-premises network will remain connected to AWS via Direct Connect. How can the architect achieve this?

A company is migrating a legacy monolithic application to a microservices architecture on AWS. The legacy application uses a single relational database. The new microservices will use purpose-built databases (DynamoDB, Aurora, ElastiCache). The migration must happen gradually with zero downtime, and both systems must run in parallel during the transition. Which architectural patterns and services should be used? (Select TWO)

An enterprise is migrating a legacy application that uses a hardcoded IP address for its database connection. The database is being migrated to Amazon RDS. How can the architect ensure the application can connect to the new RDS instance without changing the application code?
