CompTIA 220-1101 Domain 4: Virtualization and Cloud Computing

What is virtualization?

• Simulating real-life scenarios

• Creating a physical version of something

• Developing a tangible product

• Creating a virtual version of something

Which is a benefit of virtualization in a computing environment?

• Limited scalability

• Higher operational costs

• Increased flexibility

• Decreased security

Explain the concept of cloud computing.

• Cloud computing is the delivery of computing services over the internet.

• Cloud computing is the process of storing data on physical servers only.

• Cloud computing is a type of weather forecasting technology.

• Cloud computing refers to the use of floppy disks for data storage.

What are the different types of cloud services?

• LAN, WAN, MAN

• IaaS, PaaS, SaaS

• Hardware, Software, Firmware

• Private, Public, Corporate, Hybrid

What is the difference between public, private, and hybrid clouds?

• Public clouds are owned and operated by the government, Hybrid clouds are only used for personal storage, Private clouds are open to the public

• Hybrid clouds are only used for personal storage, Private clouds are open to the public, Public clouds are owned and operated by the government

• Public clouds are owned and operated by third-party cloud service providers, private clouds are operated solely for a single organization, and hybrid clouds combine public and private clouds.

• Nothing. They are all the same with different names.

Discuss the security concerns related to cloud computing.

• None. Taken care of thanks to cloud computing.

• Overly secure data encryption along with AP's.

• Data breaches, data loss, insecure APIs, shared technology vulnerabilities, lack of visibility and control

• Physical security concerns, vulnerabilities, lack of visibility and control, data breaches are a minor concern

Explain the concept of hypervisor in virtualization.

• A hypervisor hosts and runs virtual machines, allowing multiple operating systems to run on a single physical machine.

• A hypervisor manages computer viruses that infect virtual machines.

• A hypervisor is a type of virtual machine that can only run one operating system at a time.

• A hypervisor is a hardware component used to connect multiple physical machines in a virtual environment.

What are the key components of a virtual machine?

• Hypervisor, virtual CPU, virtual memory, virtual storage, and virtual network interface

• Operating system, software, and hardware

• Supervisor, virtual CPU, virtual memory, virtual storage, and virtual network interface

• OS, sandbox, VDI, Cross-platform, SaaS

What are the best practices for implementing virtualization and cloud computing in an organization?

• Ignoring the organization's needs and implementing a one-size-fits-all solution

• Little planning with minimal assessment is needed, security and training is built in

• Planning, assessing the organization's needs, selecting the right solutions, security is built in, and providing proper training

• Planning, assessing the organization's needs, selecting the right solutions, ensuring security measures, and providing proper training

What is the software called that hosts virtualized computers?

• Sandbox

• Hypervisor

• Supervisor

• Superuser
