How many domains broadcast domains are shown?
Explanation: A router defines a broadcast boundary, so every link between two routers is a broadcast domain. In the exhibit, 4 links between routers make 4 broadcast domains.
Does router have broadcast domain?
A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments. Routers and other higher-layer devices form boundaries between broadcast domains.
How many broadcast domains and collision domains are there?
Answer is B. The switch creates 12 collision domains and 1 broadcast domain. A switch creates a single broadcast domain, not separate broadcast domains so any answer with 12 broadcast domains is incorrect. A switch creates separate collision domains for each port, not a single collision domain for the entire switch.
Why do routers separate broadcast domains?
This improves the performance of the network because not all devices on a network will receive and process broadcasts. Routers separate a LAN into multiple broadcast domains (every port on a router is in a different broadcast domain).
How do I reduce broadcast domain?
Answer: C. A router can reduce the size of the broadcast domain because routers create a smaller network, thus creating a smaller broadcast domain. Some switches use Virtual LANs at Layer 3 to create smaller broadcast domains as well.
What is a Layer 2 broadcast?
A switch sends a layer 2 broadcast to all the ports that are in the same broadcast domain, ie the same vlan (which can be all ports). Some of those ports may have other switches connected, which will receive the broadcast on a port, and issue it out to all other ports on the same broadcast domain as the incoming port.
How do I reduce broadcast traffic on my network?
They are:
- Make smaller broadcast domains.
- Use multicast to unicast conversion (if available with your AP vendor)
- Increase multicast transmit rate (this should be used cautiously)
- Dynamic multicast rate adjustment (if available with your AP vendor)
Which device can stop broadcast traffic?
A router does stop broadcasts (unless configured otherwise).
Is a router Layer 2 or 3?
The most common Layer 3 device used in a network is the router. A router is able to look into the Layer 3 portion of traffic passing through it (the source and destination IP addresses) to decide how it should pass that traffic along.
How can I speed up my LAN network?
6 tips on how to optimize the speed of your home network
- Upgrade your router.
- Use security best practices for network settings.
- Keep the wireless router up to date.
- Keep all devices up to date.
- If the devices support it, connect to a 5GHz network.
How many devices are in the same broadcast domain?
In the picture above we have a network of six computers, two hubs, a bridge, a switch, and a router. The broadcast domains are marked in red. Remember, all devices connected to a hub, a bridge, and a switch are in the same broadcast domain. Only routers separate the LAN into multiple broadcast domains.
Why do I need a broadcast domain on my router?
Broadcasts sent by a device in one broadcast domain are not forwarded to devices in another broadcast domain. This improves the performance of the network because not all devices on a network will receive and process broadcasts. Routers separate a LAN into multiple broadcast domains (every port on a router is in a different broadcast domain).
Can a switch break in the broadcast domain?
Switches will never break in the broadcast domain. In, collision domain, every port on a router are in the separate broadcast domains. All ports on a switch or a hub likely to be in the same broadcast domain. The Collision domain is a network section that allows traffic to flow forward and backward.
How many collision and broadcast domain in this network?
Hub = a hub is one collision domain and a domain broadcast. So, 7 collision domains and 2 broadcasts domain. Can you guys please tell me how many collision and Broadcast domain in this network.
