Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 174

Which element enables communication between guest VMs within a virtualized environment?

Answer options

• A. hypervisor
• B. virtual router
• C. vSwitch
• D. pNIC

Correct answer: C

Explanation

The correct answer is C, vSwitch, as it allows for network communication between virtual machines within the same host. The hypervisor (A) manages the VMs but does not directly handle their communication, while a virtual router (B) typically connects different networks rather than VMs. A pNIC (D) refers to a physical network interface card, which is a hardware component, rather than a virtual element that manages VM communication.
