  • 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
