Unit Review: Virtualization and Cloud Computing (Set 2)

A Type 1 hypervisor is also called a bare-metal hypervisor because it runs directly on what?

• The physical hardware of the server

• A cloud-based container engine

• A virtual machine manager application

• The host operating system

Which of the following is an example of a Type 2 hypervisor?

• Oracle VirtualBox

• VMware ESXi

• Microsoft Hyper-V Server

• Citrix XenServer

A virtual disk file with the .vmdk extension was created by which virtualization platform?

• Oracle VirtualBox

• Microsoft Hyper-V

• KVM on Linux

• VMware

A VM is configured so it gets an IP address on the same network as the physical host. Other devices on the network can reach the VM directly. Which network adapter mode is in use?

• Bridged mode

• Host-only mode

• Internal mode

• NAT mode

Which TWO virtual disk formats are associated with Microsoft Hyper-V?

• Qcow2

• VMDK

• VHD

• VHDX

A student takes a snapshot of a VM before installing new software. The installation causes the VM to crash. What is the most appropriate next step?

• Upgrade the virtual RAM and restart the VM

• Roll back the VM to the snapshot taken before the install

• Switch the network adapter to host-only mode

• Delete the VM and create a new one

Which CPU feature must be enabled in BIOS/UEFI to allow a computer to run virtual machines on an Intel processor?

• Intel Turbo Boost

• Intel VT-x

• Intel Hyper-Threading

• Intel SpeedStep

Containers differ from virtual machines primarily because containers share what resource from the host?

• Physical CPU cores

• The host operating system kernel

• The hypervisor layer

• Virtual disk storage

A developer needs to test an application on both Windows and Linux without using two physical computers. Which virtualization use case best describes this scenario?

• Disaster recovery failover

• Cross-platform development

• Legacy application support

• Network segmentation testing

Select all that apply: Which of the following are valid strategies for mitigating VM escape attacks?

• Granting all VMs administrator access to the host

• Using resource isolation between VMs

• Configuring network segmentation between VMs

• Running all VMs on the same virtual network
