What the exam tests

What to know about Full Virtualization

Tests understanding of hypervisors, virtual machines, resource allocation, and host vs. guest OS requirements.

Identify Type 1 vs Type 2 hypervisors and their use cases.

Understand virtual machine resource allocation (CPU, RAM, storage).

Recognize host vs. guest operating system roles.

Know virtualization security and isolation requirements.

Why learners struggle

Why Full Virtualization questions are commonly missed

Learners often confuse Type 1 and Type 2 hypervisors, and misunderstand VM resource limits versus host capabilities. The abstract nature of virtualized hardware makes it hard to apply to real scenarios.

·Type 1 vs Type 2 hypervisor — which runs directly on hardware.
·Host vs guest OS — which controls physical resources.
·Overcommitment — VM resources can exceed host physical limits.
·Snapshot vs backup — snapshot is not a full backup.
·Virtual switch vs physical switch — network isolation differences.
·Hardware compatibility — guest OS may lack drivers for virtual hardware.

Watch out for

Common Full Virtualization exam traps

▸Confusing Type 1 hypervisor with Type 2 (e.g., VMware ESXi vs Workstation).
▸Thinking a VM can use more resources than the host has.
▸Assuming all hypervisors support the same guest OS features.
▸Forgetting that snapshots capture state, not backups.

You are configuring a libvirt bridge network. Which file should you edit on a Debian/Ubuntu system to create a bridge interface 'br0' that includes 'eth0'?

Trap 1: /etc/sysconfig/network-scripts/ifcfg-br0

This is for RHEL-based systems.

Trap 2: /etc/libvirt/qemu/networks/br0.xml

This file defines a virtual network, not the host interface.

A
/etc/sysconfig/network-scripts/ifcfg-br0
Why wrong: This is for RHEL-based systems.
B
/etc/network/interfaces
Standard configuration file for bridge interfaces.
C
/etc/netplan/01-netcfg.yaml
Netplan is used on newer Ubuntu, but /etc/network/interfaces is the classic answer for generic Debian.
D
/etc/libvirt/qemu/networks/br0.xml
Why wrong: This file defines a virtual network, not the host interface.
