What defines a broadcast domain?
A broadcast domain is the portion of a network sharing the same layer 2 segment. Broadcast messages from hosts are sent to every port in their broadcast domain, thus hosts inside a broadcast domain can reach each other directly.
Is broadcast domain same as VLAN?
Each VLAN is an individual broadcast domain because a broadcast in a given VLAN will never reach any ports in other VLANs. Normally, a port carries traffic only for the single VLAN to which it belongs. For a VLAN to span multiple switches on a single connection, a trunk is required to connect two switches.
What is broadcast domain IP?
In each network, a broadcast IP is assigned only once. It is always the last IP address of the subnet. The broadcast address — where all host bits are set to “1” as already mentioned — is therefore: 192.128. 64.255 in this example.
Do VLANs separate broadcast domains?
Virtual LANs (VLANs) allow network administrators to subdivide a physical network into separate logical broadcast domains. On a standard Layer 2 network, all hosts connected to a switch are members of the same broadcast domain; and broadcast domains can only be physically separated across different switches by routers.
How many broadcast domains can a switch have?
1 broadcast domain
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.
Which device is used to communicate between broadcast domains?
– Active Hub:- These are the hubs that have their own power supply and can clean, boost, and relay the signal along with the network. – Passive Hub :- These are the hubs that collect wiring from nodes and power supply from the active hub. – Intelligent Hub :- It works like active hubs and includes remote management capabilities.
How many broadcast domains?
– 4 collision domains and 3 broadcast domains – 7 collision domains and 2 broadcast domains – 8 collision domains and 1 broadcast domain – 6 collision domains and 2 broadcast domains
How many broadcast domain is on switches?
The switch establishes 12 collision domains and one broadcast domain. A collision domain is a group of ports that use inter-frame spacing to determine which frames are received on each port. A broadcast domain is a group of ports that pass all broadcast packets sent their way.
What are broadcast domains created with?
What is a Broadcast Domain? Unlike collision domains, a broadcast domain is created when a group of computers are connected to the same network segment (same VLAN), making them listen to any broadcast message that is sent on the network segment.
