What are the advantages of VLAN trunking?
VLANs provide the following advantages:
- VLANs enable logical grouping of end-stations that are physically dispersed on a network.
- VLANs reduce the need to have routers deployed on a network to contain broadcast traffic.
- Confinement of broadcast domains on a network significantly reduces traffic.
When would you use a VLAN trunk?
VLAN trunking enables the movement of traffic to different parts of the network configured as a VLAN. A trunk is a point-to-point link between two network devices that carry more than one VLAN. With VLAN trunking, you can extend your configured VLAN across the entire network.
Which are the two trunking protocols?
Trunking Protocol Standards. There are two trunking protocols used on modern communication networks: Inter-Switch Link (ISL) from Cisco and the aforementioned nonproprietary IEEE 802.1Q. Of the two, IEEE 802.1Q is the industry standard. Even Cisco switches now use IEEE 802.1Q (dot1q) by default.
What are two advantages of VLANs?
Advantages of VLAN VLAN allows you to add an additional layer of security. It can make device management simple and easier. You can make a logical grouping of devices by function rather than location. It allows you to create groups of logically connected devices that act like they are on their own network.
What are two benefits of using a VLAN?
The Real Advantages of a Virtual LAN (VLAN)
- help with network efficiency by reducing extraneous traffic;
- enhance security by creating a virtual boundary around that business unit;
- improve bandwidth performance by limiting node-to-node and broadcast traffic;
What are the benefits of the VLAN Trunking Protocol?
The VLAN Trunking Protocol offers the benefit of maintaining configuration consistency throughout the whole network. This is credited to the fact that VTP utilizes trunk frames for managing any changes made to the VLANs in that particular network.
Which is statement describe two of the benefits of VLAN?
VTP allows routing between VLANs. VTP allows a single switch port to carry information to more than one VLAN. VTP allows physically redundant links while preventing switching loops. VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information.
How are Trunk ports used to distinguish between VLANs?
In order to distinguish between frames from different VLANs, trunk ports add identification tags to the frames. Hence the name, tagged ports. A trunk is a point-to-point link between two network devices that carry more than one VLAN. In the diagram above, devices 1 and 2 have established Native VLANs with Switch 1.
What happens if you don’t have a VLAN?
Without VLANs, a broadcast sent from a host can easily reach all network devices. Each and every device will process broadcast received frames. It can increase the CPU overhead on each device and reduce the overall network security.
