A financial services company runs a critical transactional application backed by an Amazon RDS PostgreSQL DB instance. Currently, the database is deployed in a single Availability Zone (AZ). Due to compliance regulations, the database layer must be redesigned to ensure high availability.

An enterprise healthcare platform hosts its critical medical imaging application in the `us-east-1` Region. The application runs on Amazon EC2 instances distributed across three Availability Zones (AZs) and requires concurrent, POSIX-compliant read/write access to shared storage for active patient scans. Active scans must be immediately resilient to AZ-level failures. Scans older than $90$ days must be transitioned to a lower-cost tier to optimize costs, but must remain accessible within an emergency retrieval window of under $5$ minutes. Additionally, a disaster recovery (DR) site in the `us-west-2` Region must be maintained using a pilot light strategy. The DR site has a target Recovery Point Objective (RPO) of $15$ minutes and a Recovery Time Objective (RTO) of $10$ minutes. Which storage architecture meets all of these requirements with the lowest operational complexity?

The latency from ingestion to S3 must not exceed 5 minutes ($300\text{ seconds}$). The architecture must be high-performing and require minimal operational overhead. Which two actions should a solutions architect recommend to meet these requirements?

An enterprise runs a critical transactional application backed by an Amazon RDS for PostgreSQL database instance in the us-east-1 Region.

The workload is highly dynamic, with throughput requirements spiking up to $800\text{ MB/s}$ during peak rendering times. Which storage solution should a solutions architect recommend to meet these requirements with the highest performance and scalability?

A financial auditing firm hosts a document management system on AWS where millions of PDF records are stored in an Amazon S3 bucket. The compliance team mandates a highly resilient storage architecture that protects against a total AWS Region outage. The disaster recovery plan dictates a Recovery Time Objective (RTO) of less than 15 minutes and a Recovery Point Objective (RPO) of under 15 minutes. Which storage strategy should a solutions architect implement to satisfy these requirements?

A company is replicating large daily backups from their on-premises data center to Amazon S3. The data replication requires a consistent network throughput of at least $3\text{ Gbps}$ during peak transfer windows. Currently, the company uses a single AWS Site-to-Site VPN connection to AWS, but they are experiencing severe replication delays. Which solution should the solutions architect implement to meet these requirements?

A solutions architect is designing a solution to ingest real-time streaming data from web application logs and store the data in Amazon S3. The logs must be converted from JSON to Apache Parquet format before storage to optimize query performance in Amazon Athena. The architect wants to implement a fully managed, serverless solution with minimal operational overhead.

Which AWS service should the solutions architect use to meet these requirements?

A financial analytics platform runs a simulation engine on a fleet of 120 Linux EC2 instances. The simulation requires concurrent, shared access to a POSIX-compliant file system. The instances must read and write transient datasets simultaneously. During peak workloads, the simulation engine generates an aggregate write throughput of $6\text{ GB/s}$ ($6,000\text{ MB/s}$) and requires sub-millisecond metadata latencies. Which storage solution meets these performance requirements with the lowest operational complexity?

A solutions architect is designing a storage system for a high-performance rendering application running on a cluster of Linux EC2 instances. The cluster requires concurrent read and write access to a shared file system that can scale throughput dynamically. Which storage options should the solutions architect recommend? (Select TWO.)

A healthcare provider is deploying a medical imaging application on Amazon EC2 instances across multiple Availability Zones in a primary AWS region. The application requires a shared file system that supports POSIX-compliant file operations and allows concurrent read and write access from all EC2 instances.

Which combination of storage configurations will meet these requirements? (Select TWO.)

A financial service provider is designing a real-time fraud detection and auditing solution.
