A financial services company is designing a new cloud application. The application requires two distinct data storage tiers: a highly available relational database that can scale automatically to handle transactional records, and a flexible, low-latency NoSQL database to store unstructured user preference metadata. Additionally, the company wants to minimize administrative overhead while adhering to AWS architectural best practices. Which TWO of the following services or deployment strategies should the company choose?

A company is migrating its customer order processing system to AWS. The system requires a relational database that supports standard SQL queries and transactional integrity (ACID compliance). The company wants to minimize administrative overhead by offloading operating system patching and database backups to AWS. They also want to avoid a monolithic design where transactional processing and historical data analytics are combined into a single database. Which AWS service should the company use to host the transactional database?
A digital health startup is developing a mobile application to connect patients with doctors. The company wants to launch the service quickly without making significant upfront investments in physical servers or leasing data center facilities. Instead, they choose to host the application on AWS and pay only for the hourly compute resources they consume. Which benefit of the AWS Cloud is best illustrated by this scenario?
A startup is establishing its initial AWS environment and wants to secure access controls for its development team and applications running on Amazon EC2. Which of the following actions represent AWS-recommended security best practices? (Select TWO)

A financial institution runs a legacy risk analysis batch job twice a day. The job takes approximately 45 minutes to execute and requires custom kernel-level security patches and configurations to run its proprietary simulation binary. Which AWS compute service should the institution select to host this workload?
A digital publishing company hosts its content management system on Amazon Elastic Compute Cloud (Amazon EC2) instances within a public subnet. Following a security audit, the team needs to implement a rule that blocks a specific list of malicious IP addresses from reaching any resources within that subnet. Additionally, the security team notes that the control must evaluate both inbound and outbound traffic separately since it does not automatically track connection states. Which AWS resource should the company configure to meet these requirements?
A systems administrator needs to accomplish two tasks on AWS: first, define and provision a stack of resources using a repeatable template, and second, write a Python application that programmatically interacts with AWS services. Which two tools or services are designed for these tasks?

A digital media platform is migrating its video transcoding system to AWS. The system currently runs on a single high-performance server where video uploads, transcoding jobs, and metadata storage are handled by the same software process. High demand for video uploads frequently causes the entire server to run out of memory and crash, failing all ongoing transcoding jobs. The company wants to redesign this architecture on AWS using cloud design principles. Which of the following architectural changes should the company implement to align with AWS Cloud design principles? (Select TWO.)

A company's system administration team needs to implement two specific tasks on AWS:
1. Define the architecture and resource settings of a new Virtual Private Cloud (VPC) using version-controlled, reusable templates.
2. Automate a nightly task that scripts the upload of local backup logs from an on-premises administrative server to an Amazon S3 bucket.
Which of the following AWS deployment and operating methods are best suited for these respective tasks? (Select TWO.)

A logistics company needs to run a short database cleanup script every hour. The script takes approximately two minutes to execute. The company wants to implement this solution with the lowest possible operational overhead and pay only for the exact duration that the script runs.
Which AWS compute service should the company use to meet these requirements?
A logistics company is migrating its containerized supply-chain application to AWS. The architecture requires two types of storage: first, a persistent, high-performance block storage volume attached to a single Amazon EC2 instance running a transaction database; second, a shared file storage system that can be mounted simultaneously by multiple EC2 instances across different Availability Zones to process configuration templates. Which two AWS storage services should the company select to meet these requirements?

A global logistics enterprise is migrating its central order-processing system to AWS. The workload requires a relational database that supports complex SQL joins and strict ACID transactions across multiple tables. The database storage must scale automatically up to to handle peak seasonal data. Additionally, to satisfy disaster recovery requirements, the database must replicate data to a secondary AWS Region with a recovery point objective (RPO) of seconds and a recovery time objective (RTO) of less than one minute. Which AWS service should the enterprise select to meet these requirements?
A company is migrating its web application to the AWS Cloud. The current architecture relies on a single monolithic database. To align with AWS design principles, the cloud architect recommends decoupling the database tier by using a fully managed relational database for transactional customer data, and a fully managed NoSQL database for rapid, low-latency session data. Which two AWS database services should the company select to meet these requirements? (Select TWO.)

A media enterprise is designing a highly resilient database architecture on AWS. The system must meet two requirements:
1. Achieve high availability with synchronous replication to prevent data loss in the event of a single data center outage.
2. Provide disaster recovery capabilities that can survive a complete regional disaster.
Which deployment strategy best satisfies these requirements while minimizing write latency for the primary database?
A ride-sharing company is deploying an application on AWS that processes passenger location coordinates. To ensure data privacy, the developer wants to encrypt this coordinate data while it is transmitted from the passenger's mobile app to the application backend on AWS. Under the AWS Shared Responsibility Model, which of the following is the customer's responsibility in this scenario?
A healthcare organization is migrating an imaging application to AWS. The application requires a shared storage solution that can be mounted concurrently by hundreds of Amazon EC2 instances distributed across multiple Availability Zones. The files must be accessible via standard file system protocols (POSIX-compliant), and the storage capacity must scale automatically as images are uploaded. To minimize costs, any images not accessed for 30 days must be transitioned to a lower-cost tier, but they must still be available for immediate, millisecond-range retrieval when requested by a clinician. Which storage solution should the organization implement?
A company is building a high-performance computing (HPC) application on AWS that runs across a fleet of Linux-based Amazon EC2 instances. The application has two distinct storage requirements: first, it requires high-throughput, lowest-latency block storage for storing temporary scratch files that are discarded when the instances terminate; second, it requires a shared, POSIX-compliant directory structure that all EC2 instances in the fleet can mount simultaneously to read and write application configuration files. Which AWS storage solutions should the company select to meet these requirements? (Select TWO.)
