CompTIA Updated 220-1201 Exam Questions and Answers by celia

Mesh networks rely on multiple access points (or mesh nodes) to create a seamless, self-healing network. Each access point communicates with others to extend coverage and improve reliability without requiring a wired backbone for each AP.

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.

Identifying changes made to the system is the next step to troubleshoot why an application no longer launches, as recent changes often cause such issues.

Why Not A (Research the symptoms): Research is broader and should come after identifying changes.

Why Not C (Determine which steps need to be performed): This comes after identifying the issue.

Why Not D (Check the vendor ' s website): This is a later step if further guidance is needed.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, troubleshooting methodology​.

A. Check the product manual for the procedure:

When hardware is not easily accessible, always consult the product manual for proper disassembly procedures. Forcing the cover can damage the laptop or void the warranty.

Product manuals often provide step-by-step instructions for safely accessing internal components.

Incorrect Options:

B. Use a pry tool to force the cover open: Forcing the cover can cause physical damage to the device.

C. Insert the wireless card into the M.2 slot: This step cannot be performed until the cover is properly removed.

D. Try to move the cover by sliding it in all directions: Randomly sliding the cover can cause damage if the correct removal method is not followed.

Key Takeaway: Always refer to the product manual to ensure safe and proper disassembly of laptop components.
