1) What is the purpose of a VM (Virtual Machine) a) A virtual machine lets you run another operating system or app inside your computer as if it were a separate machine. b) A virtual machine is a physical computer used to store data. c) Is a machine that is virtualized d) A virtual machine is software that only improves internet speed. 2) What is desktop virtualization? a) Desktop virtualization separates the desktop environment from the physical device, allowing users to access their desktop and apps from any system. b) Desktop virtualization is a type of physical desktop computer. c) Desktop virtualization is software that removes viruses from a desktop. d) Desktop virtualization only improves internet speed. 3) What is VDI? a) VDI is a server-based technology that hosts, manages, and provides access to virtual desktops. b) VDI is a type of video display interface for monitors. c) VDI is a type of hard drive used for virtual machines d) VDI is software that cleans and optimizes your computer. 4) what is the difference between virtualization and emulation? a) Virtualization uses a hypervisor to run virtual machines using the computer’s hardware, while emulation imitates hardware or firmware without relying on the CPU. b) Virtualization and emulation are exactly the same thing. c) Virtualization does not use the system’s hardware.Emulation creates isolated virtual machines on a server. Emulation creates isolated virtual machines on a server.Emulation creates isolated virtual machines on a server. d) Emulation always requires a hypervisor to function. 5) what is the difference between type 1 and type 2 hypervisor a) Type 1 hypervisor runs directly on the computer’s hardware (bare metal), Type 2 hypervisor runs on top of an existing operating system. b) Type 1 can only run one virtual machine, and Type 2 can run many. 6) what are some examples of type 1 hypervisors?  a) VMware ESXi, Microsoft Hyper-V (Windows Server), KVM b) VMware Workstation, VirtualBox, Hyper-V for Windows clients c) none of the answers are correct d) Kaspersky, MacAfee, Malwarebytes 7) what are some examples of type 2 hypervisors? a) VMware Workstation, VirtualBox, Hyper-V for Windows clients b) VMware ESXi, Microsoft Hyper-V (Windows Server) c) Hyper V d) all the answers are correct 8) how do you know if your computer can run Hyper V? a) open the Command Prompt or the PowerShell and type systeminfo. b) open the cmd and run nestat c) open cmd and run ipconfig d) cmd 9) what is the file extension for virtual box a) .di b) .vdi c) .vbox d) .vrb 10) what is the file extension for vmware a) .vmdk b) ,ware c) .vmw d) .vmsp 11) what is the file extension for hyper v a) .vhdx b) .vhd c) .vjd d) .hyv 12) how much ram does a vm generally use a) 16-18g b) 1g c) 2-4g d) 5g 13) what is bridged networking?  a) gives a virtual machine direct access to the host’s network and its own IP address. b) Bridged networking is used only for wireless devices. c) Bridged networking only works without an IP address. d) Bridged networking means the VM shares the same IP address as the host. 14) what does NAT mean in the VM sense?  a) NAT gives the virtual machine network access using a private IP address instead of a direct external one. b) NAT allows the VM to control the host’s operating system. c) NAT is used only for Bluetooth connections. d) NAT is a type of antivirus software for virtual machines. 15) what does host only networking mean in the VM sense? a) Host-only networking creates a private network where VMs can talk to each other but not to the external network b) Host-only networking connects VMs directly to external networks. 16) what security practices should you use when trying a vm?  a) configure the host securely, update the virtualization software, update the VM OS and apps, and monitor CVEs. b) update graphics card c) update cpu d) use older software because it is more stable 17) What is a short-term way to reduce application instability in cross-platform virtualization? a) Use different operating systems for each VM b) Connect all VMs directly to the internet c) Remove the hypervisor entirely d) Make sure VMs run the same OS and version 18) What is a long-term solution to simplify cross-platform virtualization? a) Run more type 2 hypervisors b) Use cloud services or container-based systems c) Avoid using virtual machines altogether d) Run more type 3 hypervisors 19) What is VM sprawl? a) A network connection problem b) When the number of VMs becomes too large to manage c) method for reducing hypervisor costs d) type of virtualization software 20) How can VM sprawl be reduced? a) consolidate hypervisors and use a VM life-cycle management tool b) Disable VM image libraries c) Avoid updating virtual machines d) Increase the number of type 1 hypervisors 21) What is generally considered the better option when working with virtual machines? a) Type 1 hypervisors b) Type 2 hypervisors c) Emulators d) Host-only networking 22) What is containerization? a) A type of hardware used to store VMs b) . OS-level virtualization that runs multiple isolated systems on a single OS kernel c) A tool for speeding up network connections d) A type of hypervisor used for virtual machines 23) How is a container different from a virtual machine? a) A container requires more virtual hardware b) . A container is simpler and usually runs a single application c) A container uses its own hypervisor d) . A container always needs a separate OS for each instance 24) What is a main benefit of Docker containers? a) hey require dedicated hardware for each container b) They package applications to be portable across systems c) They run full operating systems by default d) They replace the host OS entirely 25) Why are containers often less resource intensive than virtual machines? a) They share a single OS kernel and don’t need full virtual hardware b) They require multiple OS kernels c) They emulate physical machines entirely d) they use more virtual hardware 26) what are some examples of containers?  a) Docker, Podman, and LXC. b) vmware c) trashbin.exe d) .vdi, .vmdk  27) What is a sandbox in software development? a) A type of physical server used only for storage b) A tool used to clean viruses c) An isolated environment for development, testing, or training d) A permanent production server 28) What is a key feature of a sandbox environment? a) It is always connected to production servers b) It must always be container-based c) It is isolated and resets to a clean state each time it runs d) It stores all previous testing data permanently 29) What happens to a sandbox after testing is complete a) It saves all changes automatically b) It resets to a clean state for the next use c) It deletes the host operating system d) It becomes a production server 30) where can a sandbox be ran?  a) on a physical server, in a virtual machine, as a container, or as specially programmed software, b) in a LLM 31) what does sanboxing do? a) Sandboxing allows programs and processes to be run in an isolated environment, to limit access to files and the host system. b) allows the host os to not connect to the network 32) what is revision control software? a) Revision control software tracks and manages changes to source code so multiple developers can work on the same project without losing work. b) A tool that deletes old versions of code permanently. c) A tool used only to design user interfaces. d) A program that prevents developers from editing code. 33) Why is revision control important in collaborative development? a) It prevents code from running on multiple platforms b) It ensures all developers work from a stable and shared version of the code c) It automatically fixes errors in the source code d) It eliminates the need for testing
