The platform requires a resilient storage architecture that includes a shared file system for active course media files which must be concurrently accessible by all EC2 instances. Additionally, database backups must be stored with high durability, ensuring a Recovery Time Objective (RTO) of $5$ minutes and a Recovery Point Objective (RPO) of $24$ hours. Which two storage configurations should a solutions architect recommend to meet these requirements?

A financial services company hosts a global web application across multiple AWS Regions. The primary infrastructure is in the us-east-1 Region, containing an Application Load Balancer (ALB) and an Auto Scaling group of EC2 instances. To meet strict recovery time objective (RTO) requirements, the company deploys a replica of the environment in the eu-central-1 Region as a standby. The application serves a mix of cacheable static assets and highly dynamic, non-cacheable transactional API endpoints under /api/*. The architecture must ensure minimal latency, immediate failover to the standby region during an outage without relying on client-side DNS caching, and full support for all HTTP write methods (POST, PUT, DELETE) on the transactional endpoints. Which solution should a solutions architect recommend to meet these requirements with the least operational complexity?

An educational institution is migrating its student enrollment system to AWS and will use Amazon RDS for SQL Server. The database must remain highly available within the primary AWS Region with a recovery time objective (RTO) of less than 2 minutes in the event of an Availability Zone failure. Failover must be completely automated, requiring no updates to the database endpoint in the application's configuration. Which configuration will meet these requirements?

A global company hosts a dynamic financial API across Application Load Balancers (ALBs) in the us-east-1 (primary) and eu-west-1 (secondary standby) Regions. The API requires ultra-low latency SSL/TLS handshakes, protection against Layer 7 SQL injection attacks, and immediate failover to the secondary region if the primary region's ALB starts returning HTTP 502 or 504 errors. The failover process must occur within seconds without relying on client-side DNS updates, and operational complexity must be kept to a minimum. Which of the following combinations of actions should the solutions architect take to meet these requirements? (Select TWO.)

A company is hosting a production web application on AWS that uses an Amazon RDS for MySQL DB instance. The database must be designed to survive the failure of a single Availability Zone (AZ) with minimal downtime and automatic failover. Additionally, the application requires read scaling to handle a high volume of reporting queries.

Which combination of configurations should a solutions architect implement to meet these requirements? (Select TWO.)

A company wants to improve the resiliency and availability of its static website hosted on Amazon S3. The website experiences occasional origin availability issues during regional outages. Which two configurations should a solutions architect implement to build a resilient content delivery solution? (Select TWO.)

A company is migrating its transactional application to Amazon RDS. To prevent downtime during an infrastructure failure or an Availability Zone outage, the solutions architect must configure the database for automatic failover to a standby instance in another Availability Zone with zero manual intervention. Which database configuration should the solutions architect recommend?

An automotive engineering firm is designing a disaster recovery solution for its on-premises computer-aided design (CAD) file server, which holds $40\text{ TB}$ of data. The firm has defined a Recovery Point Objective (RPO) of $4\text{ hours}$ and a Recovery Time Objective (RTO) of $2\text{ hours}$. During normal operations, on-premises users must access these files with sub-millisecond local latency. In the event of a local site failure, the files must be immediately accessible from a highly available and resilient environment in AWS. Which storage architecture meets these requirements most cost-effectively?

A global manufacturing firm runs a quality-control imaging system across several physical factories. The local factory systems require low-latency access to raw imaging data generated during the last 30 days. After 30 days, the data must be archived in the cloud, where it must remain durable and highly available for regulatory audits, with a Recovery Time Objective (RTO) of 5 hours. To protect against a regional disaster, all cloud archives must be replicated to a secondary AWS Region with a Recovery Point Objective (RPO) of 15 minutes. Which combination of actions should a solutions architect recommend to satisfy these requirements? (Select TWO.)

A solutions architect is configuring an active-passive disaster recovery strategy in Amazon Route 53. The primary application runs on an Application Load Balancer (ALB), and the backup site is a static website hosted on Amazon S3. Which of the following Route 53 record configurations must the solutions architect create to implement this failover mechanism? (Select TWO.)

A solutions architect is designing a highly resilient architecture for a web application. The application's static assets are stored in a primary Amazon S3 bucket in one AWS Region. The architect needs to ensure that the assets remain available even if the primary S3 bucket experiences an outage, by failing over to a backup S3 bucket in a different Region with minimal operational complexity. Which configuration will meet these requirements?

A company hosts a media portal on AWS that serves high-traffic static images and video clips. The static assets are stored in an Amazon S3 bucket in the us-east-1 Region. To ensure maximum availability, the company replicates these assets to another S3 bucket in the us-west-2 Region. The company wants to implement a solution that caches content globally to reduce latency for users. The architecture must automatically serve assets from the backup Region if the primary S3 bucket returns server errors (HTTP 500-class). Additionally, the portal must be protected against application-layer (Layer 7) HTTP flood attacks. The solution should minimize latency and operational overhead.

Which combination of actions should a solutions architect take to meet these requirements? (Select two.)

A healthcare provider is deploying a patient prescription tracking application across two AWS Regions: $us-east-1$ (Primary) and $us-west-2$ (Secondary). The application backend uses an Amazon Aurora PostgreSQL DB cluster.
