A user reports that a virtual machine running on a workstation is extremely slow, especially during high I/O operations. The host has 16 GB of RAM, an SSD, and a quad-core CPU. The VM is configured with 8 GB RAM and 4 vCPUs. What is the most likely cause of the performance issue?
A technician is troubleshooting a VM that fails to boot with an error 'Operating system not found'. The VM was just created from an ISO file. What is the most likely cause?
A small business runs a legacy application that requires Windows 7. The company wants to upgrade all desktops to Windows 11 while still running that application. Which virtualization solution would allow the application to run on the new OS without compatibility issues?
A company uses a Type 1 hypervisor for production servers. A technician needs to migrate a running VM from one host to another without any downtime. Which feature should be used?
A virtual machine running a database server experiences frequent disk I/O bottlenecks. The host has multiple physical disks. Which configuration change would most effectively improve performance?
A technician needs to deploy a virtual machine that will be used for a short-term project and then deleted. The VM must not consume excessive storage space initially. Which virtual disk type should be chosen?
A user complains that a virtual machine running on a laptop shuts down unexpectedly when the laptop is unplugged from power. The host has power management settings set to 'Balanced'. What is the most likely cause?
A company needs to deploy a virtualized environment where each VM must be isolated from others for security reasons, but all VMs share the same physical network. Which virtual networking configuration should be used?
A technician is setting up a virtual machine for a developer who needs to test software across multiple OS versions. The VM must have direct access to a USB dongle for licensing. Which VM configuration setting must be enabled?
A company wants to consolidate five physical servers into one host to reduce power and cooling costs. Each server runs a different operating system. Which virtualization technology should be used to achieve this?
A technician is troubleshooting a VM that fails to boot with the error 'Operating system not found.' The VM was created from a template that uses a virtual SCSI controller. The technician verifies that the ISO file is attached to the virtual DVD drive and the boot order is set to DVD first. What is the most likely cause of the error?
A technician is deploying a new virtual machine on a Type 2 hypervisor (hosted) for software testing. The host machine runs Windows 10 Pro with 16 GB RAM and a quad-core CPU. The test application requires 4 GB RAM and two virtual CPUs. After creating the VM with those settings, the technician notices the host becomes extremely sluggish even when the VM is idle. What is the most likely reason for this?
A company uses VMware vSphere to run multiple VMs on a single ESXi host. A user reports that their VM suddenly lost network connectivity, but other VMs on the same host are working fine. The technician checks the virtual switch configuration and finds that the VM’s virtual NIC is connected to a port group that has no active uplinks. What should the technician do to restore connectivity?
A company uses virtual machines for its production environment. A technician needs to perform maintenance on the host server without disrupting the VMs. The technician wants to move the VMs to another host in the cluster while they are running. Which feature must be configured to allow this?
A small business runs a single physical server hosting three virtual machines (VMs) for file sharing, database, and email. The server has 32 GB of RAM, and each VM is allocated 8 GB. Users report that the file-sharing VM is extremely slow. The hypervisor shows the host has 4 GB of RAM free. Which of the following is the most likely cause of the performance issue?
A company plans to migrate a physical server running a legacy application to a virtual machine to reduce hardware costs. The application requires direct access to a proprietary PCIe card installed in the physical server. Which virtualization feature must the hypervisor support to allow the VM to use this card?

A technician is tasked with deploying a virtualized environment for a small office using a single server. The server has 64 GB RAM, two 6-core CPUs, and a RAID 10 array. The technician needs to run four VMs: a domain controller (4 GB), a file server (8 GB), a web server (4 GB), and a database server (16 GB). After deployment, the database server is performing poorly.
