With this question, about CDP, the exhibit gives us the Bravo router IP is 10.1.1.2

The answer says we can tell from the output the Alpha router IP is 10.1.1.1.  How? It could be a few different ones depending how it is subnetted

The answer is correct.

As the .2 Ip is on a /30 network.

Therefore only two IP's are usable, as the other 2 IP's relate to the network & broadcast.


10.1.1.0 - Network
10.1.1.1- Alpha
10.1.1.2 - Bravo
10.1.1.3 - Broadcast

Excellent spot - I didn't read the end of the question where it says the subnet - thanks for that
