CompTIA A+ Certification Core 2 (220-1102) - Virtual LANs (VLANs)

The video tutorial covers the setup and configuration of VLANs on a managed switch, explaining how VLANs can separate network devices without additional hardware. It details the process of assigning ports to VLANs and introduces port security to enhance network safety. The tutorial also provides an overview of Software Defined Networking (SDN), highlighting its benefits in reducing manual configurations and improving network scalability.

What is the primary benefit of using VLANs in a network?

• To increase the speed of the network

• To separate network traffic without additional hardware

• To reduce the number of cables needed

• To enhance wireless connectivity

Why do managed switches require an IP address?

• To enable wireless connectivity

• To allow configuration through a web interface

• To increase data transfer speed

• To connect to the internet

What is the default VLAN ID that all ports are initially a part of?

• VLAN 2

• VLAN 1

• VLAN 0

• VLAN 3

How can VLANs affect device communication on a switch?

• They increase the speed of communication

• They prevent devices on different VLANs from communicating

• They enable wireless communication

• They allow all devices to communicate freely

What is the purpose of port security on a switch?

• To enhance wireless connectivity

• To increase the speed of data transfer

• To prevent unauthorized devices from connecting

• To allow more devices to connect

What does SDN stand for in networking?

• Software Defined Networking

• Standard Data Node

• Secure Data Network

• Simple Device Network

What is a key advantage of SDN over traditional networking?

• It uses less power

• It requires no configuration

• It separates the control plane from the data plane

• It is cheaper than traditional networking
