Скачать или смотреть 20B.1 Virtualization Concepts Virtual Switches and NICs | Network+ N10-008

In this CompTIA Network+ (N10-008) video, we explore virtualization concepts related to virtual switches (vSwitches) and virtual NICs (vNICs)—crucial for modern network and data center operations.

You’ll learn how virtualization affects network design and how traffic is handled between VMs, hosts, and external networks through virtualized networking components.

This lesson is mapped to Objective 20B.1 – Explain virtualization concepts including virtual switches and virtual NICs.

🔍 What You’ll Learn in This Video
✅ 1. What is Virtualization in Networking?
Overview of server and network virtualization

Benefits: Cost savings, scalability, hardware abstraction

✅ 2. Virtual Network Interface Cards (vNICs)
Each VM has one or more vNICs

vNICs connect to virtual switches

MAC addressing in a virtualized environment

IP addressing and virtual network segmentation

✅ 3. Virtual Switches (vSwitches)
Function of vSwitches in hypervisors (VMware, Hyper-V, KVM)

Layer 2 switching between VMs

Internal, external, and private network types

VLAN support on virtual switches

✅ 4. Connectivity Between VMs and the Physical Network
Bridged, NAT, and host-only network types

How virtual traffic is routed to the external world

Use of virtual firewalls, load balancers, and virtual appliances

📌 Mapped to Network+ N10-008 Objective 20B.1
