   An administrator needs to back up a VM before applying a major software update. The VM is running a production workload and cannot be powered off. Which hypervisor operation allows the administrator to capture the VM's current state without shutting it down?

   • AMemory overcommitment to free up resources.
   • BSnapshot, which captures the VM's disk and memory state at a point in time.
   • CLive migration to move the VM to another host.
   • DCPU reservation to guarantee performance during the update.

   Which component is a virtual CPU (vCPU) in a virtual machine?

   • AA physical processor that is dedicated to a single VM
   • BA logical processor that the hypervisor presents to a VM, backed by physical CPU cores
   • CA reserved portion of the host's RAM that acts as a CPU cache

   What is a key benefit of virtualization in terms of resource efficiency?

   • AIt eliminates the need for physical servers entirely
   • BIt automatically reduces the power consumption of the physical host to zero
   • CIt allows multiple VMs to share the same physical hardware, increasing utilization
   • DIt guarantees that each VM uses exactly the same amount of CPU

   A Type 1 hypervisor host is running several VMs. One VM is running a critical application that requires consistent CPU performance. The administrator wants to ensure this VM gets a guaranteed share of the physical CPU. Which hypervisor feature should be used?

   • ACPU reservations, which guarantee a minimum amount of CPU for the VM.
   • BCPU affinity, which pins the VM to specific physical cores.
   • CMemory overcommitment, which allows the VM to use more memory.
   • DLive migration, which moves the VM to a less busy host.
