   How does a hypervisor provide virtual memory to a virtual machine?

   • AIt allocates a dedicated portion of physical RAM exclusively for the VM and does not allow any other VM to use it.
   • BIt maps the VM's virtual memory addresses to physical memory addresses, potentially using techniques like memory overcommitment.
   • CIt uses a virtual memory file stored on disk for all memory operations, eliminating the need for physical RAM.
   • DIt emulates a fixed amount of memory that is always equal to the physical RAM installed on the host.

   A data center administrator is planning to consolidate multiple physical servers onto a single high-performance host. The workloads are production-critical and require low latency and high throughput. The administrator wants to maximize performance and minimize overhead. Which hypervisor deployment model should be used?

   • AInstall a type 2 hypervisor on a hardened Linux host and run all VMs on top of that OS.
   • BUse a container runtime on the physical host to run the workloads without virtualization overhead.
   • CInstall a type 1 hypervisor directly on the server hardware and manage VMs through a hypervisor management console.
   • DInstall a type 2 hypervisor on a Windows Server and use Hyper-V to create VMs.

   A VM running a critical database is about to undergo a major software upgrade. The administrator wants to be able to revert to the pre-upgrade state quickly if the upgrade fails. The VM is currently running and cannot be shut down for an extended period. Which action should the administrator take?

   • AExport the VM to an OVF template.
   • BMigrate the VM to another host using vMotion.
   • CClone the VM to a new VM and run the upgrade on the clone.
   • DCreate a snapshot of the VM before starting the upgrade.

   How does a virtual switch forward traffic between two virtual machines on the same physical host?

   • AIt forwards the frames directly between the virtual NICs without sending them to the physical network.
   • BIt drops the traffic because VMs on the same host cannot communicate directly.
   • CIt routes the traffic using Layer 3 information.
   • DIt sends the traffic out to the physical network and back in through the uplink.

   A data center administrator is planning to deploy a new virtualization platform for a high-performance computing (HPC) workload. The workload requires low latency and high I/O throughput. The administrator wants to minimize overhead and maximize performance. Which hypervisor type should they choose?

   • AType 2 hypervisor running on Windows Server.
   • BType 2 hypervisor running on a Linux host.
   • CType 1 hypervisor running directly on the hardware.
   • DContainer runtime on a physical host.
