Lesson 7: Summarizing Virtualization and Cloud Concepts Flashcards
Flashcard:
What is the main security requirement of a virtualization workstation configured to operate VMs within a sandbox?
A sandbox means that the VM environment should be isolated from the host and from other VM environments. A sandbox is often used to investigate malware. If the sandbox is secure, the malware can be executed and observed without the risk of it spreading to other systems (VM escaping).
Flashcard:
What is a Type 2 hypervisor?
Hypervisor software that must be installed as an application running on a host OS. A Type 1 (or bare metal) hypervisor is installed directly to the host hardware.
Flashcard:
You need to provision a virtualization workstation to run four guest OSs simultaneously. Each VM requires 2 GB system RAM. Is an 8 GB workstation sufficient to meet this requirement?
No. The host OS and/or hypervisor also requires system memory. If the host also has a 2 GB requirement, you would only be able to launch three of the VMs simultaneously.
Flashcard:
A company has contracted the use of a remote datacenter to offer exclusive access to platform as a service resources to its internal business users. How would such a cloud solution be classed?
As a private deployment model
Flashcard:
A cloud service provides a billing dashboard that reports the uptime, disk usage, and network bandwidth consumption of a virtual machine. What type of cloud characteristic does this demonstrate?
Metered utilization
Flashcard:
A technician provisions a network of virtual machines running web server, scripting environment, and database software for use by programmers working for the sales and marketing department. What type of cloud model has been deployed?
This is a platform as a service (PaaS) model. Infrastructure as a service (IaaS) would only provision the VMs and network without the software. It is not software as a service (SaaS) because the web server and database come without applications.
Flashcard:
When users connect to the network, they use a basic hardware terminal to access a desktop hosted on a virtualization server. What type of infrastructure is being deployed?
Virtual desktop infrastructure (VDI)
