CCNP Virtualization Practice Question
Which TWO statements about virtual switching in a hypervisor environment are correct?
⚠ Common exam trap
Cisco often tests the misconception that virtual switches are physical devices or that they perform Layer 3 functions, when in fact they are software-based Layer 2 forwarding engines that support VLANs and uplink connectivity.
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 virtual switch can be connected to a physical network through uplink ports.
A virtual switch connects to the physical network through uplink ports, which are typically mapped to physical NICs on the hypervisor host. This allows VMs on the virtual switch to communicate with external networks, making option A correct.
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 virtual switch can be connected to a physical network through uplink ports.
Why this is correct
Correct. Uplink ports map to physical NICs to provide connectivity to the physical network.
- ✗
A virtual switch does not support VLAN tagging.
Why it's wrong here
Incorrect. Virtual switches support 802.1Q VLAN tagging for traffic segmentation.
- ✗
A virtual switch performs routing between different subnets.
Why it's wrong here
Incorrect. Virtual switches operate at Layer 2 only; routing requires a router or Layer 3 switch.
- ✓
A virtual switch forwards frames between virtual machines based on MAC addresses.
Why this is correct
Correct. Virtual switches use MAC address tables to forward frames.
- ✗
A virtual switch is a physical device installed in the hypervisor host.
Why it's wrong here
Incorrect. A virtual switch is a software-based switch running within the hypervisor.
