Practice: Client-Side Virtualization and Hypervisors

A company runs VMware ESXi directly on server hardware with no underlying operating system. Which hypervisor type is this?

• Type 1, because it must be installed inside another VM.

• Type 1, because it runs directly on the bare metal hardware.

• Type 2, because it requires a host OS to function.

• Type 2, because it shares the host kernel with guest VMs.

A developer installs VirtualBox on a Windows 11 laptop to run a Linux VM. Which hypervisor type best describes VirtualBox in this setup?

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

• Type 1, because it provides direct access to the CPU

• Type 2, because it isolates the guest OS from all network traffic

• Type 1, because it runs on physical server hardware

A technician needs to roll back a VM to a known good state after a failed software update. Which feature should the technician use?

• A virtual disk format conversion

• A VM snapshot or checkpoint

• A bridged network adapter configuration

• A CPU virtualization extension toggle

A student wants to run virtual machines on a desktop PC. Which TWO CPU features must be enabled to support hardware-assisted virtualization?

• Intel VT-x on an Intel processor

• AMD Cool'n'Quiet for thermal management

• AMD-V on an AMD processor

• Intel Hyper-Threading for multi-core processing

A VM's virtual disk is stored as a .vmdk file. Which virtualization platform primarily uses this disk format?

• Oracle VirtualBox in its default configuration

• Microsoft Hyper-V

• KVM with QEMU

• VMware products such as Workstation and ESXi

A VM needs to appear as a separate device on the corporate network with its own IP address assigned by the network's DHCP server. Which virtual network adapter mode should be configured?

• Bridged, so the VM connects directly to the physical network

• NAT, so the VM uses the host as a gateway and shares its IP

• Internal, so the VM communicates only with other VMs

• Host-only, so the VM shares the host's IP address

A QA engineer wants to test a suspicious installer in an isolated environment where it cannot affect the host machine or the production network. Which virtualization use case does this describe?

• Application sandboxing

• Cross-platform development testing

• Legacy application support

• Disaster recovery failover

Select all that apply: Which virtual disk formats are associated with Microsoft Hyper-V?

• VMDK

• Qcow2

• VHD

• VHDX

A VM is configured so it can only communicate with the host machine and other VMs on the same host, with no access to the external network. Which network adapter mode is being used?

• Bridged, which connects the VM to the physical LAN.

• NAT, which routes VM traffic through the host's IP.

• Host-only, which limits traffic to the host and local VMs.

• Internal, which allows only VM-to-VM traffic with no host access.

A security analyst discovers that a malicious VM on a shared host has gained access to the hypervisor layer and can read memory from other VMs. What is this attack called?

• Snapshot rollback exploit

• Network segmentation breach

• VM escape

• Hypervisor type switching
