Authentic CompTIA Certification Exam 220-1201 Questions Answers

According to the CompTIA A+ Core 1 (220-1201) virtualization objectives, a Type 1 hypervisor is known as a bare-metal hypervisor because it installs directly onto the physical hardware of a system rather than running on top of a traditional operating system. This architecture allows the hypervisor to manage hardware resources—such as CPU, memory, storage, and networking—without the overhead of a host operating system. Because of this direct interaction with the hardware, Type 1 hypervisors typically provide higher performance, better scalability, and improved stability compared to Type 2 hypervisors.

Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V (bare-metal deployment), and Citrix XenServer. These hypervisors are commonly used in enterprise data centers, cloud infrastructure, and large virtualization environments where multiple virtual machines must run efficiently on a single physical server. ???? ️

Option A (Host OS required) describes a Type 2 hypervisor, such as VMware Workstation or Oracle VirtualBox, which runs on top of an existing operating system. Option C (Lightweight OS) may describe some hypervisor environments but is not the defining characteristic. Option D (Local configuration options) is also not specific to Type 1 hypervisors.

Therefore, the key characteristic that defines a Type 1 hypervisor is that it performs a bare-metal server installation directly on the hardware

The correct answer is A. NFC (Near Field Communication) .

According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices, NFC is commonly used for short-range wireless communication between devices. In the context of mobile printing:

NFC-enabled printers allow a user to tap a mobile device (phone or tablet) to the printer to initiate a print job instantly without needing to configure Wi-Fi credentials or use cables.

This is particularly common in mobile-friendly environments like offices or public kiosks.

Why the other options are incorrect:

B. Hotspot : Provides an Internet connection, not a direct mobile-to-printer interface.

C. Infrared : Legacy technology largely replaced by NFC and Wi-Fi; rarely used in modern printers.

D. USB : Requires a wired connection, not suitable for sending a print job wirelessly from a mobile device.
