What else can I help you with?
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
Switches can create by grouping a number of ports into a broadcast domain?
VLANs.
Can cisco layer 2 support vlan?
Yes, Cisco Layer 2 switches support VLANs (Virtual Local Area Networks). VLANs allow network segmentation by creating separate broadcast domains within the same physical network infrastructure. This capability enhances network performance and security by isolating traffic among different groups of users or devices. Cisco's implementation of VLANs follows the IEEE 802.1Q standard, enabling the tagging of Ethernet frames for proper routing between VLANs.
What types of collision domains do vlans break up?
VLANs (Virtual Local Area Networks) break up collision domains primarily within a switched network environment. Each VLAN creates a separate broadcast domain, which means that devices within one VLAN do not receive broadcast traffic from devices in another VLAN. This segmentation reduces unnecessary traffic and collisions, enhancing overall network performance. Additionally, since switches operate at Layer 2, each port connected to a device in a VLAN represents its own collision domain, further isolating traffic.
What can be done to reduce the broadcast traffic?
To reduce broadcast traffic, network segmentation can be implemented through the use of VLANs, which limits broadcast domains and confines broadcast messages to specific groups. Additionally, configuring routers and switches to filter or limit broadcast packets can help manage their flow. Implementing protocols like IGMP snooping can also optimize multicast traffic and minimize unnecessary broadcasts. Lastly, regularly reviewing and optimizing network configurations can help identify and eliminate sources of excessive broadcast traffic.

What describes a VLAN?
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.
Which technology is responsible for logically segmenting a network into common broadcast domains?
VLANAnswer Explanation: A virtual LAN (VLAN) allows endpoints to be grouped together as though they were on the same network segment, regardless of their physical location within the network. It creates a common broadcast domain that the members of the VLAN share regardless of the physical switch to which they are attached. VLANs provide a means for grouping users with common needs, and they can be used to segregate traffic from other areas of the network.
What are the two ways to logically segment a network?
The two primary ways to logically segment a network are through Virtual Local Area Networks (VLANs) and subnetting. VLANs allow for the creation of distinct broadcast domains within a single physical network, enabling better traffic management and security. Subnetting involves dividing a larger IP network into smaller, manageable sub-networks, which enhances performance and improves organization by isolating network traffic. Together, these methods help in optimizing network efficiency and security.
Which vtp mode is capable of creating only local vlans and doesnot synchronize with other switches inthe vtp domain?
Transparent mode
How do you reduce network congestion?
There are several ways to reduce network congestion. Subnetting and adding routers will break up broadcast domains and traffic. Adding VLANs will do the same while adding security. Upgrading the speed of NICs and wiring, i.e. moving from 10BaseT to 100 or 1000, will reduce congerstion as will moving from half duplex transmissions to full duplex transmissions.
