An enterprise is launching a new microservice on Amazon Elastic Container Service (Amazon ECS) that needs to write data to an Amazon DynamoDB table. Which configuration represents the most secure method for granting the microservice the necessary permissions?
An enterprise is migrating a legacy, monolithic document management system to AWS. The application requires a storage solution that supports POSIX file permissions and file-locking capabilities. It must be concurrently accessed by a fleet of auto-scaling Linux EC2 instances across multiple Availability Zones, as well as on-premises servers via an existing AWS Direct Connect connection. The performance requirements dictate that throughput must scale dynamically and automatically with the workload's I/O activity, without requiring manual provisioning of throughput capacity. Which AWS storage solution best meets these requirements with the least operational overhead?
A company is designing an application architecture on AWS and needs to select storage solutions for two different use cases. First, they need low-latency, temporary block storage to hold temporary scratch files and cache data that can be safely discarded when the EC2 instances are stopped. Second, they need a low-cost storage solution to archive historical records that are rarely accessed but must be retrievable within a few hours. Which TWO AWS storage options should the company select to meet these requirements?

A university research team needs to provision a standardized set of AWS resources—consisting of an Amazon Virtual Private Cloud (Amazon VPC), three Amazon EC2 instances, and an Amazon RDS database—for multiple student projects. They want to define this entire architecture in a single YAML template so they can easily deploy, update, and tear down identical environments for each project. Which AWS service is designed to meet this requirement?
A startup in the agriculture technology sector wants to test a new machine learning model for crop yield prediction. The development team needs to provision several GPU-enabled virtual servers to run experiments over the weekend, with the plan to terminate them immediately afterward. Instead of waiting weeks to procure and configure physical hardware on-premises, they deploy these instances on AWS within minutes. Which benefit of the AWS Cloud does this scenario directly illustrate?
A startup is launching a real-time multiplayer gaming application. The architecture must satisfy three requirements:
1. Provide single-digit millisecond latency for compute workloads to users in a specific metropolitan area that does not have an AWS Region.
2. Provide high availability and fault tolerance for the central database, protecting against physical data center disasters.
3. Cache static game assets globally to reduce load times for international players.
Which of the following deployment strategies correctly leverage AWS Global Infrastructure components to meet these requirements? (Select TWO.)

A media company is planning the launch of a new streaming service. They expect their subscriber base to grow steadily over the next three years, requiring their infrastructure to expand to handle this long-term growth. However, they also need their infrastructure to automatically scale up during Friday evening peak hours and scale down during weekday nights to minimize costs. Which AWS Cloud design principle is specifically demonstrated by the ability to automatically scale resources up and down in response to short-term demand fluctuations?
A logistics company, FleetRoute, operates a package tracking application that experiences high traffic during business hours and very low usage overnight. The company is migrating this workload from an on-premises data center to the AWS Cloud to optimize its infrastructure spending. Which two of the following represent core cloud economics concepts or benefits that the company will realize after this migration?

An operations manager who travels frequently needs a convenient, visual way to check the status of Amazon EC2 instances and perform basic troubleshooting tasks, such as restarting an instance, directly from a web browser. Which AWS tool or interface is designed for this type of manual, interactive management?
A company is planning to deploy a new application on AWS and has identified two specific compute requirements:
1. A containerized API microservice that runs continuously and must scale dynamically without the team managing or provisioning any underlying virtual servers.
2. A short-lived database logging utility that only executes for a few seconds whenever a new record is added to a database.
Which of the following AWS compute services should the company select to meet these requirements? (Select TWO.)

An IoT company deploys telemetry collection servers on Amazon EC2 instances within a custom subnet. The cloud practitioner configures a Network Access Control List (Network ACL) at the subnet level to allow inbound TCP traffic on port 8883 from the internet. Although the EC2 instances' Security Groups are configured to allow all outbound traffic, the external sensors are unable to receive acknowledgment responses from the servers. Which of the following configuration changes is required to resolve this issue and allow the acknowledgment traffic back to the sensors?
A boutique clothing retailer plans to launch a seasonal marketing campaign. Instead of purchasing physical servers and networking hardware to host their promotional website in a local data center, the retailer deploys the website on AWS to pay only for the virtual resources they consume during the campaign. Which benefit of the AWS Cloud is best illustrated by this scenario?
