SRWE CHAPTER 3 – VLANS | COMPLETE PRACTICE QUESTIONS, ANSWERS &
STUDY GUIDE 2026/2027
VLAN - ✔✔Virtual Local Area Network- Logical group of devices that become a separate broadcast
domain (subnet)
Default VLAN - ✔✔By default all ports on Cisco switches are a member of the default VLAN 1
Data VLAN - ✔✔a VLAN carrying user-generated traffic
Native VLAN - ✔✔A VLAN that can carry untagged traffic across an 802.1q trunk link.
Management VLAN - ✔✔A VLAN specifically setup to allow remote administration of network devices
Voice VLAN - ✔✔a VLAN dedicated to support Voice over IP (VoIP) traffic
VLAN Trunk - ✔✔A physical link that can carry traffic on more than one VLAN through logical tagging.
VLAN Tagging - ✔✔Switch adds a header to the Ethernet frame that identifies the VLAN the ingress
port is assigned to
IEEE 802.1q (Dot1q) - ✔✔The standard that is used on trunk links
QoS (Quality of Service) - ✔✔A set of parameters that controls the level of quality provided to different
types of network traffic. (VoIP)
Normal Range VLANs - ✔✔1-1005
Extended Range VLANs - ✔✔1006-4096
VTP (VLAN Trunking Protocol) - ✔✔Cisco's protocol for exchanging VLAN information over trunks. VTP
allows one switch on a network to centrally manage all VLANs.
Switch(config)# VLAN 10 - ✔✔Creates VLAN 10 on the switch
Switch(config-VLAN)#name marketing - ✔✔Names VLAN 10 "marketing"
Switch(config-if)# Switchport mode access
Switch(config-if)#switchport access VLAN 10 - ✔✔Places an end device in access mode and adds the
selected interface to VLAN 10
