Scenarios: Client-Side Virtualization and Hypervisors

Priya works as a junior IT technician at a regional hospital. She needs to set up a virtual machine on a workstation so that staff can test a legacy billing application without affecting the main operating system. Her supervisor tells her the workstation already has Windows 11 installed and that she should install a hypervisor on top of it.

Which type of hypervisor is Priya's supervisor describing?

• A Type 2 hypervisor, because it does not support virtual network adapters

• A Type 2 hypervisor, because it runs on top of an existing operating system

• A Type 1 hypervisor, because it manages multiple physical servers

• A Type 1 hypervisor, because it runs directly on the hardware

Priya wants to make sure the workstation's CPU can support virtualization before she installs the software. Which CPU feature should she confirm is enabled?

• Intel Hyper-Threading or AMD Simultaneous Multithreading

• Intel VT-x or AMD-V virtualization support

• Intel Quick Sync or AMD Video Codec Engine

• Intel Turbo Boost or AMD Precision Boost

Priya finishes setting up the VM and wants to protect her work before she installs the legacy billing application. What is one action she should take, and why is it helpful?

Carlos is an IT support intern at a software development company. His team uses Docker containers to run and test different versions of a web application. A new developer named Amara asks Carlos why the team uses containers instead of full virtual machines for this task.

Which statement best explains why containers start up faster than virtual machines?

• Containers share the host operating system kernel instead of running their own OS

• Containers store data in VMDK files, which load more quickly than other formats

• Containers use a Type 1 hypervisor that bypasses the host hardware

• Containers include a full guest operating system, which is optimized for speed

Carlos also sets up a separate VM on his workstation to test an application that could contain malware. What is the main security risk he should be aware of when running that VM?

• Virtual disk fragmentation, where the VHDX file slows down the host CPU

• Bridged networking, where the VM automatically shares files with all containers

• Snapshot corruption, where saved states are overwritten by the guest OS

• VM escape, where malicious code breaks out of the VM and affects the host system

Name one step Carlos should take to reduce the security risk of running a potentially malicious application inside the VM.
