Virtualization and Cloud Computing Flashcards
Company A uses several SaaS products such as Gmail and Google Docs along with a customized private cloud for its proprietary apps. Which of the following best describes the Company A’s cloud computing strategy?
Public cloud
Hybrid cloud
Community cloud
Hybrid cloud
A hybrid cloud combines public cloud (in this case, SaaS) and private cloud solutions
Company B is planning to make the same applications available via cloud or network services to desktops and tablets. Which of the following is Company B planning to implement?
Virtual application streaming
Private cloud
SaaS
Virtual application streaming
Virtual application streaming makes apps available to a variety of platforms via cloud or network services
Your company is going to use cloud services to develop software, and the software will then be available as a cloud service. Which pairing accurately reflects what services will be used, in the correct order?
IaaS, PaaS
PaaS, SaaS
SaaS, IaaS
PaaS, SaaS
Platform as a Service (PaaS) is the use of a complete cloud-based software development environment. Software as a Service (SaaS) makes the software available for use via the cloud
Which of the following in a community cloud scenario is the grouping of servers and infrastructure for use by multiple customers?
Virtual desktop
Synchronization apps
Resource pooling
Resource pooling
In a community cloud scenario, the cloud service provider typically implements resource pooling, which is the grouping of servers and infrastructure for use by multiple customers but in a way that is on-demand and scalable
Your company needs access to unlimited resources to promote rapid elasticity and on-demand swings in requirements, but wants to pay only for the resources it actually uses. What arrangement is your company looking for?
Measured service
Hybrid cloud
Metered service
Metered service
Metered service provides unlimited access to resources on a pay-for-what-you-use basis
Company C has set up a computing lab where it plans to install VirtualBox on Linux and Windows workstations and use it to run older versions of Linux and Windows to provide customer support. Which of the following best describes how Company C is using virtualization?
Type 1 virtualization
Bare metal virtualization
Type 2 virtualization
Type 2 virtualization
Type 2 virtualization runs within an installed operating system and relays requests to the hardware to the host operating system, whereas Type 1 virtualization directly interfaces with the computer’s hardware
When is the size of the virtual hardware (such as RAM and drive size) set during the VM creation process?
After installing the OS into the VM
Before installing the OS into the VM
Before starting the VM creation process
Before installing the OS into the VM
This information is used to set up the virtual machine, so it must be provided when the VM is created and before the OS can be installed
Company D has set up virtualization on several late-model Intel and AMD systems running high-performance processors using the recommended settings in the hypervisor for each VM, but the VMs are running very slowly. Which of the following is the most likely cause?
Hardware virtualization support is not enabled in the UEFI firmware.
VMs are using too much RAM.
Hardware virtualization support is not enabled in the OS.
Hardware virtualization support is not enabled in the UEFI firmware.
High-end Intel and AMD processors have support for hardware virtualization. However, if it not enabled in the firmware, virtualization will run very slowly
Customer E is running Windows 10 Pro and wants to install a Linux-based VM in Hyper-V. Which of the following must the customer do for this to work? (Choose two.)
Turn on Hyper-V in Windows Features
Run Windows Update
Scan the host system for viruses
Restart the system
Turn on Hyper-V in Windows Features
Restart the system
For this to work, hardware virtualization support must first be enabled in the UEFI/BIOS. Second, Hyper-V needs to be turned on in Windows Features. Finally, enabling Hyper-V requires the system to be restarted
A customer is having a problem with the network hardware on the host Windows computer for her VMs. Which of the following will help her diagnose the problem?
Check Device Manager in each VM
Disable/re-enable the virtual NIC in each VM
Check Device Manager in the host computer
Check Device Manager in the host computer
To solve a problem with the host’s network hardware, the host’s diagnostic features, such as Device Manager, must be used. The virtual NIC in each VM connects to the physical network, so the VMs can’t work if the physical network connection in the host isn’t working
