A VLAN, or Virtual Local Area Network, is a logical subgroup within a network that allows devices to communicate as if they are on the same physical network, regardless of their actual location. It enhances security and performance by segmenting traffic, reducing broadcast domains, and enabling better management of network resources. VLANs are typically configured on network switches and can support various network topologies and protocols. By isolating different types of traffic, VLANs help optimize network efficiency and improve overall security.

What name is given to a vlan on an ieee 802.1q trunk whose frames are not tagged?
The name given to a VLAN on an IEEE 802.1Q trunk whose frames are not tagged is the "native VLAN." The native VLAN is used for untagged traffic on a trunk link, allowing devices that do not support VLAN tagging to communicate over the trunk. By default, VLAN 1 is designated as the native VLAN, but this can be changed to another VLAN as needed.
What is mean of shutdown vlan 17?
The command "shutdown vlan 17" is used in network configuration to disable VLAN 17 on a network switch. When executed, it effectively prevents any traffic from being forwarded through this VLAN, rendering it inactive. This can be useful for network management purposes, such as troubleshooting or reconfiguring the VLAN. To reactivate the VLAN, the command "no shutdown vlan 17" would be used.
Which statement describes the use of voice VLANS in cisco IP telephony?
The voice VLAN carries untagged traffic having special QoS markings.
How do you connect computers on separate VLAN?
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
Why should you reassign a port to another VLAN before removing the VLAN from the VLAN database?
Reassigning a port to another VLAN before removing the VLAN from the VLAN database ensures that there is no disruption in network connectivity for devices connected to that port. If a port is removed from a VLAN without reassignment, it may result in loss of access to the network for those devices, causing potential downtime and disruption. Additionally, this practice helps maintain network organization and prevents configuration errors that could arise from deleting a VLAN that still has active ports.
how are packets assigned to the VLAN?
VLAN: How are packets distributed with respect to the different classifications?
Why would packets from the router or hosts fail when trying to reach the switch management interfaces if the native VLAN were left in default?
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
What is a function or characteristic of the native VLAN?
It is the VLAN that supports untagged traffic on an 802.1Q trunk
The network administrator needs to remove the east-hosts vlan and use the switch port from that vlan in one of the existing vlans what two commands should be used when completely removing vlan 2 from?
no vlan XXX copy run star
Which statement accurately describes a switch with all access ports assigned to the same VLAN?
Performance is increased by keeping all users in the same Layer 2 network
What is the difference between vlan and inter-vlan?
VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
What is pvid?
A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.
