A startup has deployed two applications in separate Amazon Virtual Private Clouds (VPCs) within the same AWS Region. The startup needs to connect these two VPCs directly so that they can share resources securely using private IP addresses, without routing traffic through a central hub. Which AWS networking feature should the startup use to meet this requirement?

An organization is deploying several workloads with different requirements on AWS. Match each operational workload requirement to its most appropriate AWS compute service.

A retail company is preparing to migrate its e-commerce application to AWS. The project team needs to estimate the monthly costs of the proposed architecture before launching any resources, and they also require a mechanism to receive email notifications if the actual or forecasted monthly spending exceeds a predefined threshold.

Which AWS Billing and Cost Management tools should the company use to meet these requirements? (Select TWO.)

A software startup is setting up two different compute tasks on Amazon EC2:

1. A temporary testing environment that will run for exactly two weeks, where workloads are unpredictable but must run without interruption.
2. A data archiving workflow that runs overnight, can be safely interrupted without losing progress, and requires the lowest possible compute cost.

Which two Amazon EC2 pricing models are most suitable for these tasks? (Select TWO.)

A healthcare organization needs to store patient medical records for 10 years to meet regulatory compliance requirements. The records are rarely accessed after the initial treatment period, but the organization must be able to retrieve them within 3 to 5 hours if an audit occurs. The solution must minimize storage costs. Which Amazon S3 storage class is the most cost-effective choice for this scenario?

ShieldHealth Solutions, a health insurance provider, plans to migrate its member portal and monthly claims analysis pipeline from an on-premises data center to AWS. The portal experiences steady daily traffic with occasional massive spikes during annual open enrollment periods. The claims analysis pipeline runs once a month, requiring substantial compute power for a 12-hour window. Which TWO of the following describe cloud economic benefits or mechanisms that ShieldHealth Solutions will realize by moving to AWS?

A multinational company is launching a new application and needs to host its user data within the borders of Germany to comply with national regulations. Which AWS global infrastructure component should the company select to ensure the data is stored in this specific geographic location?

A company is extending its on-premises corporate office to AWS using a $10\text{ Gbps}$ AWS Direct Connect connection. The corporate network needs to access workloads deployed across $30$ different Virtual Private Clouds (VPCs) in the same AWS Region. Additionally, the security team requires that any incoming traffic from the on-premises network to the VPCs' database subnets be filtered at the subnet boundary to permit only a specific range of administrative IP addresses. Which AWS networking solution and security feature should the company implement to meet these requirements?

A company is running an application on a fleet of Amazon EC2 instances. The operations team needs to monitor the CPU utilization of the instances in real time and receive an automated notification if the utilization exceeds $85\%$ for more than $5$ minutes. Which AWS service should the company use to collect these performance metrics and trigger the notification?

An online education platform wants to expand its course offerings to a global audience. The platform needs to convert its English study guides and written lecture notes into multiple languages, including French and Spanish, while maintaining the contextual meaning of the text. Which AWS service should the platform use to meet this requirement?

A research institute, BioGenetics, currently runs its genomic sequencing workloads on an on-premises datacenter. They experience highly unpredictable computing demands, with massive spikes in resource usage during research phases followed by weeks of idle infrastructure. The institute plans to migrate these workloads to AWS to pay for resources only when they are actively running analyses, and to decommission resources when they are not in use. Which of the following represents the primary economic advantage of this migration strategy?

An organization is evaluating AWS compute services to host different types of applications and workloads. Match each workload scenario to the most appropriate AWS compute service.

An architect is designing an infrastructure strategy. The strategy requires copying database backups to a distant geographic location for disaster recovery compliance. Additionally, the application's active web servers must run in multiple isolated locations within the same area to prevent downtime from a single facility outage. Which two AWS Global Infrastructure components should the architect use to meet these requirements?

A health-tech startup hosts its patient record database on Amazon EC2 instances inside a private subnet of a Virtual Private Cloud (VPC). The security team needs to restrict incoming database traffic to only the application server instances. Additionally, any outbound response traffic from the database back to the application servers must be allowed automatically, without configuring an explicit outbound rule. Which AWS firewall option should the security team configure to meet these requirements?

A digital education platform needs to store students' course progress and quiz answer history. The data schema is simple (student ID, course ID, quiz ID, and completion status) and requires fast, predictable read and write performance that scales automatically to support millions of active users during exam weeks. The development team wants a serverless, key-value database that eliminates the operational overhead of managing database servers. Which AWS database service best meets these requirements?

A company is planning to deploy a multi-tier web application in Amazon VPC. The architecture requires that the database tier be completely isolated from the public internet, while the web servers must be accessible to the public internet. Which subnet configuration should the company use to meet these requirements?

A network administrator is conducting a one-time experiment and needs to manually configure a network connection between two Amazon Virtual Private Clouds (VPCs). The administrator wants to use a graphical, web-based interface to perform this configuration without writing any code, scripts, or infrastructure templates.

Which AWS tool or interface should the administrator use to meet these requirements?

An organization plans to expand its services globally and wants to understand how AWS structures its physical resources. Which of the following represents a physical geographical location that contains multiple isolated and physically separate Availability Zones?

A cloud architect is designing a high-availability strategy for a critical application that must comply with national data sovereignty laws. Which of the following statements correctly describe how AWS Global Infrastructure components support these requirements? (Select TWO.)

A company plans to deploy a custom database application that requires low-level kernel configuration modifications and direct control over the underlying operating system patching schedule. Which AWS compute service is the most appropriate for this workload?
