Ok whats the real answer??? On directed broadcasts...

Question: If a router has a packet destination address of 192.168.1.255. What describes the operation of the network?

2 possible answers are...

1. it will drop the packet as it is not a valid host. it is a broadcast address. And by default routers do not forward broadcasts.

2. It will forward the packet because it is a directed broadcast of the 192.168.1.0/24 network. Not a general broadcast packet.

Learned it one way in the boot camp but have been told the other way in the real world. What does Cisco want on this question?

Confused.

if you ping that address from a router, it will work.
But Routers will not forward broadcasts when they are received.
So, what does the question say?
That's the problem, it doesn't....

the answer is, what does cisco want?

Look for the best answer....to me, I'd answer #1, just as a rule of thumb....

I guess you need to just hope that if you do see a question like this, you don't have both of the answers you listed, only #1 as an option.

I am sure we'll get more information on this string from other members, and I welcome them...

If a router has a packet destination of 192.168.1.555, you have bigger problems than determining if the packet will be dropped or routed. :p
