350-401 Question #185: Real Exam Question with Answer & Explanation

Question

A server running Linux is providing support for virtual machines along with DNS and DHCP services for a small business. Which technology does this represent?

Options

• Acontainer
• BType 1 hypervisor
• Chardware pass-thru
• DType 2 hypervisor

Explanation

Explanation

A Type 2 hypervisor runs on top of an existing host operating system (in this case, Linux), allowing it to host virtual machines while the underlying OS simultaneously handles other services like DNS and DHCP - this perfectly matches the scenario described. Type 1 hypervisors (Option B) run directly on bare metal hardware without a host OS underneath, so they wouldn't share a server already running Linux services. Containers (Option A) share the host OS kernel and don't create full virtual machines with their own OS instances. Hardware pass-thru (Option C) is a feature that grants VMs direct access to physical hardware components, not a standalone virtualization technology.

🧠 Memory Tip

Think of it this way: Type 1 = "bare metal" (first contact with hardware) and Type 2 = "second layer" (sits on top of an OS). If Linux is already running before the VMs are created, the hypervisor must be Type 2 - it's the second layer on the server.
