What else can I help you with?
How many broadcast domain are created when you segment a network with 12-port switch?
Zero. No collisions can occur within a full-duplex environment, as transmit and receive operations are performed on another set of wires. Thus, no collision domains would exist. Carrier Sense Multiple Access with Collision Detection (CSMA/DC) is not part of a full-duplex network for this reason.
How do switches create collision domains?
by allowing the interconnection of segments with different speeds
When is it appropriate to introduce a router into your network?
When you want to create additional networks and /or broadcast domains.

How does a layer 2 switch create collision domains?
When using network switches, each port on the switch is its own collision domain.
How many valid subnets do you get if you borrow 3 bits?
When you borrow 3 bits from the host portion of an IP address, you can create (2^3 = 8) valid subnets. However, one subnet is reserved for the network address and another for the broadcast address, leaving you with 6 usable subnets. Thus, by borrowing 3 bits, you obtain 6 valid subnets for use.
Briefly describe about broadcast and collision domain.?
A collision domain consists of all the clients that could possibly cause a collision amongst themselves by sending a packet at the same time. Devices such as hubs create a single collision domain which means that everyone connected to the hub has the capability of causing a collision (which is a problem).A broadcast domain consists of all the clients that can receive the same broadcast packet. Unlike a collision domain this is not a problem. Think of it as those systems that are capable of receiving the broadcast message.
Which device is used to communicate between broadcast domains?
A router. The key word is create. you can not create a domain using a switch, repeater, or hub.
How many bits are borrowed from a class B host address to create 30 new subnets?
5 bits are necessary to create up to 30 subnets.
Why should you create subnets?
Subnets allow to isolate traffic within a subnet. It is beneficial not only from security perspective but also from performance.
Is it possible to create 9 subnets of equal size or do you have to create a different number of subnets?
Depending on class of network you are planning to use. For class C you can create much more then that (and for the most case for others too).
What network devices is used to create physical subnets?
routers
