How does a hypervisor allocate CPU and memory resources to virtual machines?

It gives each VM exclusive ownership of a physical CPU core and a fixed amount of RAM

It randomly assigns resources to VMs as they start up

It divides the physical resources into virtual resources and assigns them to VMs based on configured settings

It allows VMs to directly access the physical hardware without any mediation

An administrator is setting up a new VM and wants to ensure it can use multiple CPU cores for a compute-intensive application. The host has a 4-core processor. Which hypervisor setting should they configure?

Assign 1 virtual CPU and rely on the hypervisor to schedule across cores.

Assign 4 virtual CPUs to the VM.

Assign 8 virtual CPUs to the VM.

Assign 2 virtual CPUs and enable CPU affinity.

Which of the following is a common use case for virtualization in an IT environment?

Consolidating multiple physical servers into virtual machines on a single host

Providing a physical desktop for every employee

Eliminating the need for backup and disaster recovery procedures

Replacing all physical network switches with virtual switches

A university computer lab has 50 workstations. Students need access to specialized software that is only available for Windows, but the lab also needs to offer Linux for a programming course. The lab manager wants to minimize hardware costs and simplify maintenance. Which solution best balances these needs?

Use VDI to provide both Windows and Linux virtual desktops from centralized servers.

Install a Type 2 hypervisor on each workstation and run both Windows and Linux VMs.

Use application virtualization to run Windows apps on Linux workstations.

Dual-boot each workstation with Windows and Linux.

A system administrator is creating a new VM and needs to ensure it can communicate with other VMs on the same physical host without going through the physical network. Which hypervisor feature should they configure?

A virtual switch configured as an internal network.

A virtual switch connected to the host's physical NIC.

A virtual disk configured as a pass-through disk.

A virtual CPU with multiple cores.
