Flashcards: CompTIA A+ Core 1: Virtualization
What is Virtualization?
The process of creating a software-based or virtual representation of something such as applications, servers, storage, and networks
Why are virtual machines useful for working in legacy systems?
You can experiment within the legacy environment without needing legacy hardware
Why are virtual machines useful for cross-platform synchronization?
You can test products within multiple operating systems without changing hardware or boot options
What is a Hypervisor?
The virtualization layer that includes all the requisite drivers and applications to control the virtual hardware
True or False: All CPUs support virtualization
False - Most modern CPUs will, but the CPU will need to specify if it is capable
What are 3 other components that virtualization heavily utilizes?
RAM, Storage, and network resources
What is a Sandbox?
A virtualized testing environment for code or programs that mitigates the risk of catastrophic errors and allows easy rollbacks
True or False: Virtual Machines are more resistant to malware than traditional machines
False - Modern malware can detect whether it is on a VM and escape to compromise the hypervisor
What type of malware can impact all VMs on a hypervisor?
A rogue VM, it can supersede the hypervisor and compromise all the connected machines in the background
