Amazon Web Services Updated CLF-C02 Exam Questions and Answers by hayden

Amazon AppStream 2.0 is the former exam name for the service currently documented as Amazon WorkSpaces Applications. It is a fully managed application-streaming service that allows organizations to centrally host desktop applications and stream them to users. Users can access applications through supported clients or an HTML5-capable web browser without installing the complete application locally. This provides the instant, location-independent application access described in the question, making option A correct. Amazon Lightsail is a simplified service for virtual private servers, containers, databases, networking, and web application hosting. AWS Resource Access Manager allows supported AWS resources to be shared across accounts or within AWS Organizations. AWS Client VPN provides managed remote network connectivity to AWS and connected networks, but it does not host and stream desktop applications by itself. WorkSpaces Applications can maintain centrally managed application images, allowing users to access current application versions from suitable devices. For exam recognition, remember both names: older questions use Amazon AppStream 2.0, while current AWS documentation uses Amazon WorkSpaces Applications for the managed desktop application-streaming capability.

Savings Plans offer cost savings for predictable, steady workloads over a one or three-year term, with flexibility in instance family and size, making them suitable for critical workloads on EC2 instances that will run for a long term like three years. Spot Instances are more cost-effective but not suitable forcritical, predictable workloads due to potential interruptions. Dedicated Hosts and On-Demand Instances would be more costly.

The scenario describes replacing large upfront infrastructure purchases with variable, usage-based cloud expenses. In an on-premises environment, a company commonly purchases servers, storage, networking equipment, data center capacity, and supporting systems before they are used. These expenditures represent significant capital investment. By using AWS, the company can consume computing resources when needed and pay according to the applicable service-pricing model rather than upgrading and owning all underlying infrastructure. Therefore, option B is correct. Increased speed to market is another cloud benefit, because infrastructure can be provisioned rapidly, but the question specifically emphasizes minimizing capital investment. Massive economies of scale describe how AWS aggregates demand across many customers and can offer lower variable prices. The ability to go global in minutes refers to deploying applications in multiple geographic Regions without building international data centers. Those are valid cloud advantages, but neither is the main financial change described. The direct exam concept is trading capital expenditure for operating or variable expenditure, allowing the organization to avoid large speculative hardware investments and align costs more closely with actual consumption.
