A media processing company is designing a system on AWS to orchestrate and run video rendering jobs. The architecture includes:

1. An orchestration daemon that runs $24/7$ on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate to monitor job queues and manage metadata.
2. A fleet of worker nodes that retrieve tasks from an Amazon SQS queue, download large video segments, process them, and upload the results to Amazon S3. Individual rendering tasks can run for up to $3\text{ hours}$. The queue depth varies significantly throughout the day, and tasks can be safely restarted from the beginning if interrupted.
3. A persistent database layer running on Amazon RDS for PostgreSQL to store customer metadata and job configurations.

Which combination of compute selection and purchasing strategies will achieve the lowest overall cost? (Select TWO.)

A research institution is deploying a distributed high-performance computing (HPC) pipeline on AWS for genomic sequencing. The pipeline is deployed across a fleet of Amazon EC2 instances. The pipeline requires a shared storage solution that supports concurrent read and write access from hundreds of instances, delivers sub-millisecond latency, and scales throughput up to $20\text{ GB/s}$. Additionally, the solution must automatically load raw input datasets from a designated Amazon S3 bucket when files are first accessed, and export output results back to the S3 bucket upon pipeline completion.

Which combination of steps should the solutions architect take to meet these performance and integration requirements? (Choose two.)

An enterprise inventory management application uses Amazon Aurora PostgreSQL as its database engine. The application has strict resiliency requirements: it must achieve high availability within the primary AWS Region with a recovery time objective (RTO) of less than 30 seconds and a recovery point objective (RPO) of zero. Furthermore, for disaster recovery, the database must be replicated to a secondary AWS Region with an RPO of less than 5 seconds and an RTO of less than 15 minutes.

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

A solutions architect is migrating a high-frequency transactional database to an Amazon EC2 instance. The database requires a single storage volume that can deliver at least $95,000$ IOPS and $1.5\text{ GB/s}$ throughput with sub-millisecond latency. The database also requires $99.999\%$ volume durability to prevent data loss.

Which actions should the solutions architect take to meet these requirements? (Select TWO.)

A financial analytics firm runs a distributed risk-modeling application across a fleet of 80 Linux-based Amazon EC2 instances. The application requires a shared, POSIX-compliant file system with sub-millisecond latencies, capable of handling an aggregate throughput of up to $40 \text{ GB/s}$ and $100,000 \text{ IOPS}$ during peak execution. The data set is updated periodically from an Amazon S3 bucket, and the storage must support automatic replication across multiple Availability Zones to ensure high availability. Which combination of storage solutions and configurations should a solutions architect recommend to meet these requirements? (Select TWO.)

A financial services company hosts a web application across two AWS Regions: us-west-2 and eu-central-1. The application is deployed behind Application Load Balancers (ALBs) in both Regions to serve users in North America and Europe. Users are reporting high latency and poor connection stability during peak hours. The company requires a solution that minimizes latency by routing user traffic over the AWS global network backbone. The solution must also provide automatic failover in less than 30 seconds if a Region becomes unhealthy, without relying on DNS caching. Which solution should a solutions architect recommend to meet these requirements?

A company is deploying a containerized application across a fleet of Amazon EC2 instances distributed across multiple Availability Zones.
