A startup is deploying a critical database on AWS and is evaluating options for high availability and disaster recovery. The database must be resilient to localized physical events such as fires, earthquakes, or power grid failures in a metropolitan area, but the data must not leave the host country due to legal compliance. A developer suggests deploying a primary database instance in one AWS Region and a read replica in a different AWS Region within the same country, while another suggestion is to deploy the database across multiple Availability Zones within a single AWS Region. Which of the following statements correctly evaluates these proposals in the context of AWS Global Infrastructure design principles?
A cloud architect is reviewing the compute requirements for a media distribution platform. The platform has two distinct components:
1. A video rendering pipeline that requires deep customization of the underlying Linux kernel and direct access to physical GPU hardware resources.
2. A containerized metadata extraction service that runs on an event-driven basis in response to user uploads, with highly unpredictable traffic and a strict requirement to avoid managing host servers.
Which two of the following compute solutions should the architect select to meet these requirements?

A university research department is transitioning its scientific simulation workloads to AWS. These workloads run for approximately hours at the end of each month, requiring high-performance compute nodes. The rest of the month, the department only requires a single low-power server to host their results archive. The IT director is evaluating the economic impact of this migration compared to their legacy on-premises hardware.
Which of the following describes the most cost-effective provisioning strategy that illustrates the economic benefit of cloud elasticity for this workload?
A global media network is migrating its digital publishing platform to AWS. The network needs to ensure that its primary publishing database is resilient against localized disasters, such as power grid failures or flooding, within its main operating market. Additionally, the network must deliver static image and video assets to a worldwide audience with minimal delay. Which of the following AWS Global Infrastructure design decisions will meet these requirements? (Select TWO).

A municipal utility enterprise operates a smart grid analytics platform. The workload fluctuates dramatically and unpredictably based on seasonal weather patterns, leading to periods where on-premises servers run at 95% capacity, followed by weeks of near-zero utilization. To address this, the enterprise wants to migrate to a model where they only pay for resources when they are actively consumed, eliminating the need to pre-allocate hardware. Furthermore, they are mandated to quickly replicate their software environment to support municipal grids across South America and Europe with sub-second response times. Which of the following core benefits of the AWS Cloud directly support the resolution of these operational challenges? (Select TWO.)

A retail corporation is designing a hybrid cloud architecture and needs to secure its data at rest on AWS. The security compliance policy states that the keys used for encrypting financial transactions must be stored on dedicated, single-tenant cryptographic hardware controlled entirely by the customer. However, for standard application logs stored in Amazon S3, the company wants to use a fully managed service where AWS handles the physical hardware management, but the customer retains control over key policies and rotation.
Which two of the following actions should the company take to meet these requirements? (Select TWO.)

NovaSprout Organics, a distributor of organic produce, is migrating its operations to the AWS Cloud. The IT department has finalized plans for two distinct workloads:
1. The company's core inventory tracking database will be moved to Amazon RDS to eliminate the administrative burden of backups and patching, while keeping the database engine and application code unchanged.
2. The legacy customer relationship management (CRM) system, which is complex and expensive to maintain on-premises, will be decommissioned in favor of a cloud-based CRM software-as-a-service (SaaS) application.
Which two migration strategies are being utilized by NovaSprout Organics? (Select TWO)

A government contractor is deploying an application on AWS that handles classified public safety records. Compliance regulations mandate that all data at rest must be encrypted using cryptographic keys stored inside dedicated, single-tenant hardware security modules (HSMs) that are physically and logically isolated. Which option correctly identifies the AWS service that meets this requirement and the customer's responsibility for that service under the AWS Shared Responsibility Model?
A logistics company, RouteLogix, runs a fleet management application that processes vehicle telemetry. The application requires high compute capacity to run route optimization algorithms for 4 hours every morning. During the rest of the day, the system only requires minimal resources to receive and store GPS location pings. The company's management wants to understand the economic impact of migrating this workload from their on-premises data center to AWS. Which of the following describe the financial benefits of this migration? (Select TWO.)

A medical research company is designing a new cloud architecture on AWS to handle two distinct processing tasks:
1. A batch processing job that performs genome sequencing simulations. This job must run on a custom Linux distribution with a modified kernel and runs continuously for several days.
2. An image processing task that automatically runs whenever a patient uploads a medical scan to an Amazon S3 bucket. The execution time is less than a minute, and uploads occur sporadically throughout the day.
Which two AWS compute services should the company use to support these workloads? (Select two.)

A multinational company uses AWS Organizations with consolidated billing to manage its multiple departmental AWS accounts. The finance department notices that underutilized Amazon EC2 Reserved Instances (RIs) purchased by the marketing team's account are automatically applying discounts to EC2 instances running in the development team's account. To track budgets more accurately, the company wants to ensure that RI discounts are only applied to the specific account that purchased them. Which of the following actions should the AWS Organizations administrator take to achieve this?
An enterprise retail organization is preparing to deploy an e-commerce platform on AWS. The design includes running application containers on Amazon Elastic Container Service (Amazon ECS) with AWS Fargate launch type across two AWS Regions, storing structured product catalogs in Amazon Aurora, and storing media assets in Amazon Simple Storage Service (Amazon S3). Before deploying any services or writing code, the cloud financial operations team must estimate the monthly costs for this hypothetical infrastructure.
Which of the following actions should the team perform to model and estimate these projected costs? (Select TWO.)
