Cisco CCNA Certification: Defining Broadcast Domains

When you're studying to pass the CCNA exam and earn your certification, you're introduced to a great many terms that are either totally new to you or seem familiar, but you're not quite sure what they are. The term "broadcast domain" falls into the latter category for many CCNA candidates.



A broadcast domain is simply the group of end hosts that will receive a broadcast sent out by a given host. For example, if there are ten host devices connected to a switch and one of them sends a broadcast, the other nine devices will receive the broadcast. All of those devices are in the same broadcast domain.

Of course, we probably don't want every device in a network receiving every single broadcast sent out by any other device in the network! This is why we need to know what devices can create multiple, smaller broadcast domains. Doing so allows us to limit the broadcasts traveling around our network - and you might be surprised how much traffic on some networks consists of unnecessary broadcasts.

Using the OSI model, we find devices such as hubs and repeaters at Layer One. This is the Physical layer, and devices at this layer have no effect on broadcast domains.

At Layer Two, we've got switches and bridges. By default, a switch has no effect on broadcast domains; CCNA candidates know that a switch will forward a broadcast out every single port on that switch except the one upon which it was received. However, Cisco switches allow the creation of Virtual Local Area Networks, or VLANs, that are logical segments of the network. A broadcast sent by one host in a VLAN will not be forwarded out every other port on the switch. That broadcast will be forwarded only out ports that are members of the same VLAN as the host device that sent it.

The good news is that broadcast traffic will not be forwarded between VLANs. The bad news is that no inter-VLAN traffic at all is allowed by default! You may actually want this in some cases, but generally you're going to want inter-VLAN traffic. This requires the use of a router or other Layer 3 device such as a Layer 3 Switch. (Layer 3 Switches are becoming more popular every day. Basically, it's a switch that can also run routing protocols. These switches are not tested on the CCNA exam.)

That router we just talked about also defines broadcast domains. Routers do not forward broadcasts, so broadcast domains are defined by routers with no additional configuration.

Knowing how broadcasts travel across your network, and how they can be controlled, is an important part of being a CCNA and of being a superior network administrator. Best of luck to you in both of these pursuits!

CCNA / MCSE / CCNP Certification: Making Failure Work For You

Whether you're on the road to the CCNA, CCNP, MCSE, or you're on any other computer certification track, the odds are that sooner or later, you're going to fail an exam. It's happened to almost all of us, yours truly included. What you have to keep in mind in these times is that success is not a straight line. You've probably seen charts showing the growth of an industry or a business -- you know, the ones that go from left to right, and look kind of jagged. The line goes up for a while, then down a bit, then up some more, then down a little.



The key? While every business has its setbacks, the net result is that the line goes up and progress is made. That's how you want your certification pursuit and your career to go as well - upward!

I'm not asking you to be happy about failing an exam. You're allowed to get mad for a few minutes, vow to never take another exam again, and be disappointed. What you're not allowed to do is stay that way.

If you put your books away in a fit of anger, get them out. If you took some time off, it's time to get back to work. Again, there's nothing wrong with being unhappy about failing an exam. It's how you handle that failure that counts. No inventor, executive, or entrepreneur has ever been right 100% of the time. Learn something from your failure. Was your study time quality study time? Did you get some hands-on practice with the technology you're studying? Asking yourself these questions can be tough, but it can be highly valuable in making sure you don't fail the next time. And there must be a next time - because the one thing you cannot do is quit.

Besides, take it from someone who's been there - your temporary failure makes your eventual success that much sweeter.
