220-1101 Virtualization and Cloud Computing Practice Question
A technician is creating a local virtual machine for software testing. The VM must have isolated virtual networking and snapshots for rollback. Which host capability is most relevant?
⚠ Common exam trap
Candidates often confuse peripheral hardware features (like webcams or docking stations) with the core virtualization capabilities required for VM networking and rollback, leading them to overlook the hypervisor's role.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A hypervisor with virtual switch and snapshot support
A hypervisor provides the virtualization layer needed to create and manage VMs, including a virtual switch for isolated virtual networking and snapshot functionality for rollback. These features are essential for software testing environments where network isolation and the ability to revert to a previous state are required.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A biometric webcam
Why it's wrong here
A biometric webcam is an input peripheral used for authentication and video conferencing; it lacks any hypervisor, virtual switch, or snapshot mechanism. It cannot create or manage virtual machines, nor does it enable isolation or rollback of a test environment. Even if the host has virtualization software, the webcam is irrelevant to VM execution and lifecycle management.
- ✗
A laser printer with duplexing
Why it's wrong here
A laser printer with duplexing hardware is designed for printing and automatic two-sided output, with no role in virtual machine management. Its firmware may include network features, but it cannot host VMs, provide virtual networking, or revert a system to a previous state. The printing subsystem consumes memory and I/O but offers no snapshot or rollback capability.
- ✓
A hypervisor with virtual switch and snapshot support
Why this is correct
A hypervisor is the core virtualization platform that partitions physical hardware into multiple VMs and can run a guest OS for software testing. A virtual switch provides internal/ external network connectivity between VMs and the host, while snapshot support captures the VM's exact state so testers can roll back after each test run. Together these directly address isolation, networking, and reversible state—key requirements for VM-based testing.
- ✗
A docking station with USB-C power delivery
Why it's wrong here
A docking station with USB-C power delivery expands a laptop's ports, adds pass-through charging, and may support external displays, but it performs no compute, memory, or storage functions. It cannot run virtual machines, create snapshots, or provide the network abstraction needed for VM communication. The dock is a hardware peripheral, not a virtualization service.
