What this domain covers
What to know about Virtualization
Virtualization questions on this certification test your ability to deploy and manage virtualization concepts in scenario-based situations.
Core Virtualization concepts and how they apply in real-world cloud scenarios.
How to deploy virtualization correctly and verify the outcome.
Troubleshooting virtualization issues by interpreting error output and system state.
Cloud best practices and Virtualization design trade-offs tested by this certification.
Why learners struggle
Why 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 Virtualization exam traps
- ▸Selecting the most expensive service when a simpler managed option meets the requirement.
- ▸Forgetting that cloud resources must be explicitly secured — defaults are rarely secure.
- ▸Choosing a global service fix when the issue is region-specific.
- ▸Overlooking cost implications of cross-region data transfer in architecture questions.

Which TWO of the following are benefits of using network virtualization with VXLAN? (Choose two.)
Easy2Which THREE of the following are components of a Cisco ACI fabric? (Choose three.)
Easy3A network engineer configured VRF TENANT_A and moved the subinterfaces into the VRF. After the change, the CEF table shows the prefixes but the next-hop addresses are unreachable. What is the most likely cause?
Hard4Which TWO statements correctly describe characteristics of virtual device contexts (VDCs) in Cisco Nexus switches?
Easy5Match each network device to its primary function.
Medium6Match each Cisco switch security feature to its function.
Medium7A data center uses Cisco Nexus 9000 switches with VXLAN EVPN to provide network virtualization. The operations team notices that VLAN 100 (mapped to VNI 10100) is not reachable across the fabric, although other VLANs work fine. The NVE interface is up, and the EVPN address-family is configured. Which two actions should the engineer take to isolate the issue?
Hard8Which TWO statements about virtual switching in a hypervisor environment are correct?
