   A company runs a VM that hosts a critical application. The application must be available 24/7, and the company has a disaster recovery plan that requires the VM to be recoverable within 15 minutes in the event of a host failure. The VM's data is stored on local storage. Which approach should the administrator take to meet the recovery time objective (RTO)?

   • ATake regular snapshots of the VM and store them on a remote server.
   • BUse live migration to move the VM to a standby host in the event of a failure.
   • CReplicate the VM's virtual disk to a standby host and use a hypervisor feature to start the VM automatically on failure.
   • DEnable memory overcommitment to allow the VM to run on another host without moving the disk.

   Which characteristic distinguishes a Type 1 hypervisor from a Type 2 hypervisor?

   • AType 1 hypervisors require a separate management server, while Type 2 hypervisors do not
   • BType 1 hypervisors run directly on the physical hardware, while Type 2 hypervisors run on top of a host operating system
   • CType 1 hypervisors only support Linux VMs, while Type 2 hypervisors support Windows VMs
   • DType 1 hypervisors are used only in cloud data centers, while Type 2 hypervisors are used only on personal computers

   A company runs a web application on a single physical server. The server is underutilized, and the company wants to run multiple isolated instances of the application for different customers. Which approach allows this while maximizing resource utilization?

   • AUse snapshots to create copies of the application.
   • BUse live migration to move the application between servers.
   • CRun each customer's application in a separate VM on the same physical server.
   • DRun all customers' applications directly on the physical server without isolation.

   An administrator is planning to deploy a VM that will run a high-performance computing (HPC) workload. The workload is highly parallel and requires low-latency access to the physical CPU and memory. The administrator is concerned about the overhead introduced by the hypervisor. Which VM configuration is most appropriate for this workload?

   • AEnable snapshots to capture the VM state frequently for recovery.
   • BUse memory overcommitment to allow the VM to use more memory than physically available.
   • CAssign a single vCPU and rely on the hypervisor scheduler to allocate CPU time.
   • DAssign multiple vCPUs and use CPU affinity to pin the VM to specific physical cores.

   What is the main benefit of live migration of a VM?

   • AIt permanently stops the VM and deletes its virtual disks
   • BIt creates a backup of the VM on the same host
   • CIt changes the VM's operating system without rebooting
   • DIt allows the VM to be moved to another host without significant downtime
