The basic reason for splitting a network into VLANs is to reduce congestion on a large LAN. To understand this problem, we need to look briefly at how LANs have developed over the years.
Initially LANs were very flat---all the workstations were connected to a single piece of coaxial cable, or to sets of chained hubs. In a flat LAN, every packet that any device puts onto the wire gets sent to every other device on the LAN.
As the number of workstations on the typical LAN grew, they started to become hopelessly congested; there were just too many collisions, because most of the time when a workstation tried to send a packet, it would find that the wire was already occupied by a packet sent by
some other device.

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 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.
How are data frames identified and sent to the correct VLAN when exiting an Ethernet trunk?
Based on the VLAN tag.

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.
What is the purpose of the vlan database?
Vlan database is vlan.bat file which is stored in flash memory and earlier in NVRAM. It is used to store vlan information. we can take back up of this file.

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.

VLAN: How are packets distributed with respect to the different classifications?
What describes Esquivels primary purpose in her essay At the Hearth?
Her primary purpose is to entertain the reader.
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
