CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingMedium
A systems administrator needs to install a new operating system (OS) and applications on a virtual machine. After installing the OS, the VM's network connectivity is not working, and the display resolution is very low. The administrator checks the VM settings and confirms the virtual network adapter is configured correctly. What common set of tools or drivers is most likely missing from the newly installed VM?
- AHost OS updates
- BPhysical network card drivers
- CHypervisor integration tools
- DVM backup software
Show answer & explanationAnswer & explanation
Correct answer: C. Hypervisor integration tools
Hypervisor integration tools (e.g., VMware Tools, Hyper-V Integration Services, VirtualBox Guest Additions) provide optimized drivers for virtual hardware (network, video, storage) and enhance communication between the guest OS and the hypervisor. Missing these tools commonly results in poor performance, incorrect display resolution, and non-functional network adapters within the VM.
Why the other options are wrong
- A. Host OS updates are for the physical machine's OS, not directly for VM guest OS issues.
- B. Physical network card drivers are for the host machine, not typically for issues within a VM's virtual network adapter.
- D. VM backup software is for data protection, not for resolving performance or driver issues within an actively running VM.
Hypervisor Integration Tools
Software packages installed within a virtual machine's guest operating system to improve performance, usability, and management.
- Provide optimized drivers for virtual hardware (video, network, storage).
- Enhance communication between guest OS and hypervisor.
- Examples: VMware Tools, Hyper-V Integration Services, VirtualBox Guest Additions.
Memory trick: Tools make the VM run smooth and clear.
