How many collision domains and broadcast domains are there in the given network topology?
To determine the number of collision and broadcast domains in a network topology, one must analyze the devices involved. Each switch creates separate collision domains for each connected device, while a router or Layer 3 switch creates separate broadcast domains. Without a specific topology diagram or description, it's impossible to provide an exact count; however, generally, each switch adds collision domains, and each VLAN or router adds a broadcast domain.
How many frames can passthrought a24port hub at one instance in time with no colllition occurring?
Since Hubs are Physical-layer devices and do not segment collision domains (which switches do), the answer is "one". Since switch DO segement collision domains, a switch can pass as many frames as it has ports.
Which Cisco layer is responsible for breaking up collision domains?
data link
Which technology allows you to divide broadcast domains using a layer 2 switch?
VLAN
What layer of the OSI model is a Switch on?
It operates on the data link layer of the OSI model (level 2). The switch creates a separate collision domain for each port. Although some switches operate on level 3 of the model and are called multi-layer switches.
Which one of the following is the most commonly used layer 2 network device?
The most commonly used Layer 2 network device is the Ethernet switch. Ethernet switches operate at the data link layer of the OSI model and efficiently forward frames based on MAC addresses, allowing multiple devices to communicate within a local area network (LAN). They help reduce network collisions and enhance overall network performance by creating separate collision domains for each connected device.
Ws-c3560-24ps-e is layer 2 switch or layer3 switch?
It is a layer 3 switch
What is the difference between switch and router?
Routers operate at layer 3 of the OSI model while switches operate at layer 2. The data transmission form of a router is called a packet while in a switch, it is called a frame. Routers are mainly used in wide area networks while switches are used in local area networks.
What is the purpose in a network switch?
Switches connect multiple devices on a network, similar to a hub, but with one difference. Switches have the ability to "remember" which device is connected to which switch-port - and only retransmit to switch-port connecting the destination-device for which the data is intended, thereby creating multiple collision domains (which is good - less chance for lost data). In contrast, a hub simply retransmits the data to EVERY interface on it, creating one huge collision domain.
How does using a hub or a repeater affect the size of the collision domain?
A layer 1 device will extend a collision domain
Why is a switch called as layer 2 device?
because one layer is the electrical part, and the other layer is the place where the switch is on.
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.
