DDAC Lesson 1

It is a payment method for cloud computing that charges based on usage.

What cloud term is suitable for it?

What is hardware virtualization?

• Creating a virtual version of a physical computer system

• Creating a backup of computer files

• Upgrading computer hardware components

• Installing a new operating system on a computer

Describe the concept of storage virtualization.

• Abstracting physical storage resources and presenting them as a single virtual storage device

• Combining physical and virtual storage into one device

• Utilizing cloud storage for virtualization

• Creating multiple separate storage devices

What is network virtualization and how does it work?

• Network virtualization is the process of creating physical networks on a single software-based administrative entity.

• Network virtualization works by combining hardware and software resources into multiple physical network infrastructures.

• Network virtualization is the process of separating hardware and software network resources into different administrative entities.

• Network virtualization is the process of combining hardware and software network resources into a single, software-based administrative entity. It works by creating multiple virtual networks on a single physical network infrastructure.

It refers to when IT service providers allow multiple clients to access the same tools and storage space within a “pool” of resources.

Explain the difference between desktop virtualization and server virtualization.

• Desktop virtualization is used for cloud computing while server virtualization is used for local storage.

• The main difference is that desktop virtualization is for servers and server virtualization is for desktops.

• The main difference is that desktop virtualization is hardware-based and server virtualization is software-based.

• The main difference is that desktop virtualization is for desktops and server virtualization is for servers.

Explain the concept of software virtualization and its working.

• Software virtualization involves creating multiple virtual instances of software on a single physical server.

• Software virtualization works by combining hardware and software resources into multiple physical network infrastructures.

• Software virtualization is the process of separating hardware and software network resources into different administrative entities.

• Software virtualization is the process of combining hardware and software network resources into a single, software-based administrative entity. It works by creating multiple virtual networks on a single physical network infrastructure.

Explain the benefits of network virtualization.

• Improved network performance and efficiency

• Reduced network complexity

• Enhanced security and isolation

• All of the above

Explain the role of hypervisor in hardware virtualization.

• Hypervisor is responsible for creating virtual instances of hardware components on a physical server.

• Hypervisor is a backup system for computer files.

• Hypervisor is responsible for upgrading computer hardware components.

• Hypervisor is responsible for installing a new operating system on a computer.

It can increase or decrease the capacity of existing services/instances by upgrading the memory (RAM), storage, or processing power (CPU)
