A financial services company is migrating a high-frequency trading simulation platform to Amazon EC2. The platform consists of a cluster of Linux EC2 instances that require concurrent, shared access to a dataset via the NFS protocol. The workload demands sub-millisecond latencies for random file operations, sustained throughput of $4 \text{ GiB/s}$ during peak hours, and up to $100,000$ IOPS. The storage solution must also support instantaneous, space-efficient file system snapshots and clones for testing runs.

Which combination of storage configurations and client-side settings will meet these requirements? (Select TWO.)

A company needs to ingest $3\text{ MB/s}$ of transaction records from an e-commerce website. The records must be processed in the exact order they are received to maintain inventory accuracy, and then saved to Amazon S3. Which AWS service configuration provides the most suitable ingestion pipeline with the least operational overhead?

A logistics company is migrating its core shipment tracking system to AWS. The application uses a PostgreSQL database and must be resilient to a complete AWS Region outage. The solutions architect must design a disaster recovery (DR) strategy with a Recovery Time Objective (RTO) of less than 15 minutes and a Recovery Point Objective (RPO) of less than 10 seconds. Which configuration meets these requirements with the least operational overhead?

A clinical diagnostics company operates a containerized genomic analysis pipeline on Amazon Elastic Kubernetes Service (Amazon EKS) in the `eu-west-1` Region. The pipeline requires a shared, POSIX-compliant file storage layer that provides latencies of less than $1$ millisecond for active DNA sequence processing, supports concurrent read/write access from hundreds of active pods across $3$ Availability Zones, and guarantees a Recovery Point Objective (RPO) of $0$ and a Recovery Time Objective (RTO) of near $0$ in the event of an Availability Zone outage. For compliance, a copy of the processed genomic datasets must be archived in the `eu-central-1` Region with an RPO of less than $15$ minutes. If a disaster occurs in the primary Region, the archived datasets must be accessible in `eu-central-1` within a recovery RTO of $5$ minutes. Which combination of storage configurations will meet these resilience and recovery requirements? (Select TWO.)

A company has deployed 15 VPCs in the us-east-1 Region to connect different microservices for an application. Currently, the VPCs are connected using a full mesh of VPC Peering connections.
