CompTIA A+ divides hypervisors into two main categories: Type 1 (bare-metal) and Type 2 (hosted). A Type 2 hypervisor runs on top of an existing host operating system such as Windows, macOS, or Linux. It relies on the host OS for device drivers, hardware interaction, and resource management. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop.

Type 2 hypervisors are ideal for lab environments, testing, learning, and small-scale virtualization because they do not require dedicated hardware or direct hardware control. The host OS loads first, and the hypervisor runs as an application, allowing users to create and manage virtual machines from within the OS environment.

Option B describes a Type 1 hypervisor, which installs directly on hardware without a host OS. Option A is unrelated, as firewalls are separate from virtualization technology. Option D is incorrect because hypervisors do not inherently increase CPU capabilities; they merely allocate existing hardware resources to virtual machines.

Thus, the correct and CompTIA-aligned description of a Type 2 hypervisor is that it runs on a host operating system.

When a technician encounters a burning smell, it is a critical safety issue. The first response must be to immediately power down and disconnect the device from all power sources to prevent electric shock, fire, or further hardware damage.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 – Troubleshoot common hardware problems:

"Signs of electrical issues such as burning smells, smoke, or sparks require an immediate shutdown of the system and disconnection from any power source."

After ensuring safety, the technician should inspect the hardware for visible signs of damage:

From the same Objective (4.1):

"Inspect for foreign objects, liquid damage, or burnt components. These can cause short circuits or thermal events that may damage the motherboard or other internal components."

These steps are standard practice in the industry to ensure safe and accurate diagnosis of faulty devices. Trying a different adapter (Option F) may make the problem worse, and contacting vendors (Option D) comes after initial safety and inspection.

CompTIA A+ explains that Secure Boot is a UEFI security feature that prevents unauthorized or malicious bootloaders, rootkits, and unsigned OS loaders from starting during the boot process. Secure Boot verifies digital signatures on the OS and critical boot files before allowing startup, ensuring the system has not been tampered with.

TPM (Option A) provides encryption key storage and is used for BitLocker, but alone does not block malicious bootloaders. HSMs (Option B) are enterprise cryptographic devices, not PC boot protection features. BIOS passwords (Option D) restrict access to configuration but do not protect against malicious boot-level malware.

Windows 11 specifically requires Secure Boot, making it the correct protection mechanism for preventing startup-level malware.

Thus, Secure Boot is the proper choice.

When assigning a static IP address to a network device such as a printer, the administrator must manually enter all information that a DHCP server would normally provide automatically.

CompTIA A+ networking fundamentals explain that a statically assigned host requires:

IP address (set manually)

Subnet mask (must be manually configured to define the network boundary)

Default gateway (must be manually assigned so the device can communicate outside its subnet)

DNS (also typically required, but in SOHO printer configs, it is not always mandatory unless name resolution is needed)

The question asks specifically: Which must be set manually?

The two required components for every static IP assignment in a CompTIA-compliant small office network are:

✔ B. Subnet mask

Defines the network and host portions of the IP address. Must be manually entered for static IPs.

✔ C. Default gateway

Allows communication outside the local network. Must also be manually set for static IP devices.

Why the other options are incorrect

A. DHCP

Not used in static addressing. DHCP is automatic; static addressing bypasses it.

D. DNS

Not always required for printers unless hostname resolution is needed. The question asks for what must be set manually.

E. Reservations

DHCP reservations create “static-like” addresses via DHCP, not manual configuration.

F. Exclusions

Used to prevent DHCP from assigning certain IPs; not part of configuring a static IP on a device.
