Q2. What is the purpose of virtualization?
- A.Increase RAM speed
- B.Run multiple OS instances on one machine✓ Correct
- C.Boost GPU performance
- D.Defragment hard drives
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?
- A.It runs on top of a host operating system.
- B.It is installed directly on bare metal hardware.✓ Correct
- C.It is primarily used for desktop virtualization on workstations.
- D.It requires fewer hardware resources than a Type 2 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?
- A.SaaS (Software as a Service)
- B.PaaS (Platform as a Service)
- C.IaaS (Infrastructure as a Service)✓ Correct
- D.DaaS (Desktop as a Service)
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?
- A.Operating system patching
- B.Application security
- C.Data encryption at rest
- D.Physical security of the data center✓ Correct
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?
- A.Type 1✓ Correct
- B.Type 2
- C.Hosted
- D.Emulated
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?
- A.IaaS
- B.SaaS
- C.PaaS✓ Correct
- D.DaaS
Explanation: PaaS (Platform as a Service) offers runtime environments, middleware, and development tools.
