The application tier runs on Amazon EKS. Which TWO routing and failover strategies should the architect implement to ensure the lowest latency and automatic failover? (Select TWO)

An architect is designing a highly resilient, multi-region serverless application. The application uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. Which THREE configurations are required to achieve an active-active multi-region architecture? (Select THREE)

A company is designing a disaster recovery plan for a critical application. The application uses Amazon EC2, Amazon RDS for PostgreSQL, and Amazon S3. The RPO is 1 hour and the RTO is 2 hours. They have chosen a 'Warm Standby' strategy in a secondary AWS Region. Which THREE actions should be part of this strategy? (Select THREE)

An application uses Amazon Aurora PostgreSQL. To meet disaster recovery requirements, the database must survive a region failure with an RPO of 1 second and RTO of 1 minute. Which architecture meets these requirements?

An application relies on an Amazon RDS for MySQL database. The business requires an RTO of 5 minutes and an RPO of 5 minutes in the event of a complete region failure. Which disaster recovery strategy meets these requirements MOST cost-effectively?

A company is designing a multi-region active-active architecture for a stateless web application. They need to route users to the region providing the lowest latency. If a region fails, traffic must automatically route to the healthy region. Which routing solution is BEST?

A company is designing a disaster recovery strategy for a critical application. The RTO is 4 hours and the RPO is 1 hour. They want to minimize costs while meeting these requirements. Which TWO actions represent a 'Warm Standby' architecture? (Select TWO)

A company is designing a highly resilient, multi-region architecture for a critical payment processing system. They need to ensure zero data loss (RPO=0) and automated failover. Which FOUR strategies should be implemented? (Select FOUR)

An e-commerce company requires a multi-region active-active architecture for its critical order processing system. The database layer uses Amazon Aurora PostgreSQL. The application must tolerate a complete region failure with an RPO of less than 1 second and an RTO of less than 1 minute. How should the architect design the database layer?

A healthcare company is designing a disaster recovery strategy for a critical application. The application uses EC2 instances and an RDS SQL Server database. The business requires an RPO of 15 minutes and an RTO of 4 hours. The solution must be as cost-effective as possible. Which DR strategy should the architect choose?

A company has a multi-tier application running in a single AWS Region. The database tier uses Amazon Aurora MySQL. The company wants to improve resilience by expanding to a second region. They require an RTO of less than 5 minutes and an RPO of less than 1 minute. The application tier is stateless and deployed via AWS CloudFormation. What is the MOST cost-effective architecture to meet these requirements?

A financial institution is building a highly resilient payment processing system. The system uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. The architecture must survive a complete AWS Region failure with zero data loss (RPO = 0) and an RTO of less than 1 minute. Which combination of configurations will meet these requirements? (Select THREE)

A global logistics company is designing a tracking system. IoT devices on trucks send location updates every 5 seconds via MQTT. The data needs to be ingested, processed in real-time to detect route deviations, and then stored in a data lake. The architecture must handle millions of messages per second with high reliability. Which AWS architecture is MOST appropriate?

A global financial company is designing a multi-region active-active architecture for their core trading platform. The platform uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. They need to route users to the region that provides the lowest latency. If a region fails, traffic must automatically failover to the healthy region. Which combination of Route 53 configurations should be used? (Select TWO)

An enterprise is migrating its Active Directory to AWS. They want to use AWS Managed Microsoft AD. They have a strict requirement that the directory must be highly available across two AWS Regions to survive a complete region failure. How can this be achieved?

A financial institution requires a disaster recovery strategy for its critical trading application. The application uses Amazon Aurora PostgreSQL and EC2 instances in an Auto Scaling group. The business requires an RPO of 1 second and an RTO of less than 1 minute. The solution must be highly available across two AWS Regions. Which architecture meets these requirements?

A company is designing a multi-region active-active architecture for a latency-sensitive API. The API is backed by AWS Lambda and Amazon API Gateway. Data is stored in Amazon DynamoDB. Users should be routed to the closest region, but if a region fails, traffic must automatically failover to the healthy region. Which routing solution provides the FASTEST failover and lowest latency?

A global gaming company uses Amazon DynamoDB for player profiles. Players are distributed globally across North America, Europe, and Asia. The application requires single-digit millisecond read and write latency for players in their respective regions. The data must be synchronized globally, and the architecture must handle regional failures without manual intervention. Which solution meets these requirements?

A global enterprise is deploying a new application in 5 AWS Regions. The application requires a centralized database. The database must support millions of reads and writes per second globally. Data must be strongly consistent for reads in the primary region, but eventually consistent reads are acceptable in the other 4 regions. The architecture must survive a full region outage with zero data loss (RPO=0) and an RTO of less than 1 minute. Which database solution meets these requirements?

A company is designing a multi-region active-passive architecture for a critical web application. The primary region is us-east-1, and the disaster recovery region is us-west-2. The application uses Amazon EC2, an Application Load Balancer (ALB), and Amazon Aurora PostgreSQL. The company wants to automate the failover process so that if the primary region goes down, traffic is automatically routed to the DR region. Which combination of steps should the Architect take? (Select TWO)
