CH08 Virtualization Flashcards
What is the lowest layer (bottom layer) of a bare-metal virtualization environment?
a. Hypervisor
b. Host Operating System
c. Guest operating system
d. Physical Hardware
d. Physical Hardware
The bottom layer is physical hardware in this environment. It is what sits beneath the hypervisor and controls access to guest operating systems. The bare-metal approach doesn’t have a host operating system.
You need to determine the best way to test operating system patches in a lab environment prior to deploying them to your automated patch management system. Unfortunately, your network has several different operating systems in use, but you only have one machine available to test the patches on. What is the best environment to utilize to perform the testing of the patches prior to deployment?
a. Sandboxing
b. Virtualization
c. Purchase additional workstations
d. Bypass testing and deploy patches directly into the production environment
b. Virtualization
When you have a limited amount of hardware resources to utilized but have a required to test multiple operating systems, you should set up a virtualized environment to test the patch across each operating system prior to deployment. You should never deploy patches directly into production without testing them first in the lab.
Which of the following vulnerabilities involves leveraging access from a single virtual machine to other machines on a hypervisor?
a. VM escape
b. VM migration
c. VM sprawl
d. VM data remnant
a. VM escape
Virtual machine escape vulnerabilities are the most severe issue that may exist in a virtualized environment. In this attack, the attacker has access to a single virtual host and then leverages that access to intrude on the resources assigned to different virtual machines.
You are installing Windows 2019 on a rack-mounted server and hosting multiple virtual machines within the physical server. You just finished the installation and now want to begin creating and provisioning the virtual machines. Which of the following should you utilize to allow you to create and provision virtual machines?
a. Disk management
b. Hypervisor
c. Device manager
d. Terminal services
b. Hypervisor
OBJ-2.2: A hypervisor, also known as a virtual machine monitor, is a process that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, like memory and processing. To create and provision virtual machines within the Windows 2019 operating system, you can use a Type II hypervisor like VM Ware or VirtualBox. Disk Management is a system utility in Windows that enables you to perform advanced storage tasks. Device Manager is a component of the Microsoft Windows operating system that allows users to view and control the hardware attached to the computer. Remote Desktop Services, known as Terminal Services in Windows Server 2008 and earlier, is one of the components of Microsoft Windows that allow a user to take control of a remote computer or virtual machine over a network connection.
