What is the purpose of the switch command switch port access vlan 99?
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
What layer of osi model does vlan operate?
VLAN's, or virutal local area networks, appear at the application level or Level 7 o the OSI model. VLAN's use tagging or pot+tagging to route traffic to and from a specific area (like a specific departement in a business). VLAN technology relies on ethernet connectivity throughout the network it functions on (a more ubiquitious medium than standard trunking and TCIP, etc). VLAN's require an edge switch to tag the outgoing traffic and recieve the incomming traffic and allows you to prioritize traffic (tagged v/s untagged) so you can provide services like ip telephony, video sessions, SIP, etc.
What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
What is true about vlan?
VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined as Virtual Local Area Network.
Which two statements describe VTP transparent mode operation?
A switch running in VTP Transparent mode will not participate in VLAN synchronization. With VTP version 2, it will forward VLAN traffic out its trunk interfaces.
How can a VLAN help to improve voice traffic?
A Vlan can be used to reduced the amount of background chatter on the network from other devices not used by VOIP.

When multiple VLAN are created do you need a router to move data across the VLAN even though the all VLAN are within one subnet?
No, router is not necassary. All traffic will transfer data within the network.
What are VLANs used for?
VLANs provide the capability so virtually segregate traffic on a network. VLANs work by tagging traffic packets and ensuring that packets with separate VLAN IDs are only available at ports which have been configured for that VLAN ID.
What is a function or characteristic of the native VLAN?
It is the VLAN that supports untagged traffic on an 802.1Q trunk
Which type of VLAN would accommodate untagged traffic on a 802.1q trunk port?
native vlan
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.

Which two types of traffic are always transmitted as untagged?
traffic that assigned native vlan
What feature allows the switches to pass VLAN traffic between switches?
vlan trunking protocols. eg :802.1q ,ISL
What is a good way to contain network traffic to a certain area in a network?
One of ways to do that is to use VLAN, but you need switch or router supporting. Also just single router without VLAN can separate networks isolating broadcast and collision domains. Some switches can limit broadcast domains too but they are rather expensive.
