Sample AWS Cloud Practitioner CLF-C02 Practice Questions
Q: Which of the following best describes cloud computing?
A: On-demand delivery of IT resources over the internet with pay-as-you-go pricing — Cloud computing is the on-demand delivery of IT resources such as compute, storage, and databases over the internet with pay-as-you-go pricing, eliminating the need to own and maintain physical data centers.
Q: Under the AWS Shared Responsibility Model, which of the following is the CUSTOMER's responsibility?
A: Managing IAM user permissions — Under the Shared Responsibility Model, the customer is responsible for security 'in' the cloud, which includes managing IAM user permissions, access controls, and identity management. AWS handles the physical and infrastructure layers.
Q: What is an AWS Region?
A: A geographic area containing multiple isolated Availability Zones — An AWS Region is a physical geographic area that contains multiple isolated and physically separate Availability Zones. Each Region is designed to be completely independent of other Regions for fault isolation.
Q: Which AWS service provides a visual representation of your AWS costs and usage over time?
A: AWS Cost Explorer — AWS Cost Explorer is a tool that lets you visualize, understand, and manage your AWS costs and usage over time. It provides graphs and reports to analyze spending patterns and forecast future costs.
Q: What is a key financial benefit of using AWS Cloud compared to on-premises infrastructure?
A: Trading fixed expenses for variable expenses — AWS allows companies to trade capital expense (CapEx) for variable operational expense (OpEx). You only pay for what you consume rather than investing heavily in data centers before knowing how you will use them.
Q: Which advantage of cloud computing refers to the ability to acquire resources as needed and release them when no longer required?
A: Elasticity — Elasticity is the ability to acquire resources when you need them and release them when you no longer need them. In the cloud, you can scale resources up or down quickly to match demand.
Q: A company wants to reduce the time it takes to deploy new applications from weeks to minutes. Which cloud benefit does this describe?
A: Agility — Agility refers to the speed at which cloud resources can be provisioned and deployed. AWS enables companies to spin up resources in minutes rather than waiting weeks for hardware procurement and setup.
Q: Which cloud computing model provides the customer with the MOST control over the underlying infrastructure?
A: Infrastructure as a Service (IaaS) — IaaS provides the most control because the customer manages the operating system, middleware, runtime, and applications. The cloud provider only manages the physical hardware and virtualization layer.
Q: Amazon RDS is an example of which cloud service model?
A: Platform as a Service (PaaS) — Amazon RDS is a PaaS offering because AWS manages the underlying infrastructure, operating system, and database engine patching, while the customer manages the data and application-level configuration.
Q: A company runs an application on Amazon EC2 and is responsible for patching the guest operating system. Which cloud deployment model does this represent?
A: IaaS — Amazon EC2 is an IaaS offering. With IaaS, the customer is responsible for managing and patching the guest OS, while AWS manages the host OS and physical infrastructure.
