   A small software company wants to consolidate three aging physical servers into a single new server to reduce hardware costs. The team needs to run multiple Linux and Windows workloads with minimal performance overhead and no reliance on a host operating system. Which hypervisor deployment model best meets these requirements?

   • AUse a container runtime like Docker on a minimal Linux installation and run all workloads as containers.
   • BInstall a Type 2 hypervisor such as VMware Workstation on Windows Server and run all VMs on that platform.
   • CInstall a Type 2 hypervisor such as VirtualBox on a Linux host and run all VMs on top of it.
   • DDeploy a Type 1 hypervisor such as KVM or Xen directly on the server hardware and manage VMs through it.

   A company runs a latency-sensitive application in a VM on a KVM host. The administrator needs to move the VM to a new host for hardware maintenance. The new host has a different CPU model (older generation) than the current host. The application cannot tolerate more than a few seconds of downtime, and the VM must continue running after the migration. Which approach should the administrator take?

   • ATake a snapshot of the VM, copy the snapshot to the new host, and start the VM from the snapshot.
   • BPerform a cold migration: shut down the VM, copy the disk, and start it on the new host.
   • CConfigure the VM to use a CPU model that is compatible with both hosts (e.g., a baseline model), then perform a live migration.
   • DPerform a live migration without any CPU compatibility configuration.

   A company is migrating a physical Linux server to a VM. The server runs a legacy application that depends on a specific network interface name (eth0) and a static IP address. After P2V migration, the VM boots but the network interface is renamed (e.g., ens3) and the application fails. The administrator needs to restore functionality with minimal changes to the application. What should the administrator do?

   • AChange the VM's virtual hardware to use a different network card model that preserves the eth0 name.
   • BConfigure a udev rule or systemd link file to rename the virtual interface back to eth0 and assign the static IP.
   • CReinstall the application and reconfigure it to use the new interface name.
   • DUse a container instead of a VM to preserve the original network interface name.

   A company is migrating a physical Windows Server 2012 R2 machine to a KVM-based virtual machine. The physical server uses a RAID controller and proprietary drivers. After converting the disk image and importing it into KVM, the VM fails to boot with a blue screen. What is the most likely cause and the appropriate next step?

   • AThe VM's CPU type is incompatible; change the CPU model to match the physical server exactly.
   • BThe disk image is corrupted; re-create the image using a different conversion tool.
   • CThe VM's memory is too low; increase the RAM allocation to match the physical server.
   • DThe VM lacks the necessary virtual drivers for the virtualized storage controller; install the virtio drivers into the guest before or during the boot process.

   A mid-sized company wants to build a private cloud with multiple KVM hosts, centralized VM management, live migration, and software-defined networking. They have a limited budget and prefer open-source solutions. They also need a web-based UI for administrators and users. Which solution best fits these requirements?

   • AUse systemd-machined with Open vSwitch for networking.
   • BUse oVirt with Open vSwitch for networking.
   • CUse VirtualBox with standard Linux bridges for networking.
   • DUse Proxmox VE with standard Linux bridges for networking.
