Q1. Which type of cloud service provides virtual machines?

Explanation: IaaS (Infrastructure as a Service) provides virtualized computing resources like VMs. Learn more.

Q2. What is the purpose of virtualization?

Explanation: Virtualization allows multiple operating systems to run simultaneously on a single physical machine. Learn more.

Q3. Which of the following is a key characteristic of a Type 1 hypervisor?

Explanation: A Type 1 hypervisor, also known as a bare-metal hypervisor, is installed directly onto the physical hardware of the server, without a host operating system. Examples include VMware ESXi and Microsoft Hyper-V Server. Learn more.

Q4. Which cloud computing model provides on-demand access to computing resources like virtual machines, storage, and networks, where the customer manages the OS and applications?

Explanation: IaaS provides the fundamental building blocks for cloud IT. It typically includes access to networking features, computers (virtual or on dedicated hardware), and data storage space. The customer is responsible for the OS, middleware, and applications. Learn more.

Q5. In the shared responsibility model for cloud computing (IaaS), which of the following is typically the responsibility of the cloud provider?

Explanation: In an IaaS model, the cloud provider is responsible for the security OF the cloud (e.g., physical data centers, underlying network infrastructure, virtualization hypervisor). The customer is responsible for security IN the cloud (e.g., OS, applications, data). Learn more.

Q6. Which hypervisor type runs directly on the host's hardware without an underlying OS?

Explanation: Type 1 (bare-metal) hypervisors run directly on hardware, whereas Type 2 run on a host OS.

Q7. Which cloud service model provides a complete development and deployment environment?

Explanation: PaaS (Platform as a Service) offers runtime environments, middleware, and development tools.
