Kuka51 from Russian Federation – 06 03 2012, 11:47 AM Report Spam In exam A the answer to question 2 should be BC, not CD.In exam B question 3 is organized incorrectly.I'm disappointed:( dada from Tunisia – 05 14 2012, 2:44 PM Report Spam thank u very valid kc10boom from United States – 05 08 2012, 8:29 AM Report Spam This looks recycled from Daniel's dump. Test J, #10 doesn't list a subnet in the question and also in the answer it calculates the # of available host incorrectly (24-2=14??). Question K, #2 is incorrect. All the mac addresses listed in the question are all in the mac address table so the switch isn't going to flood all the ports when it has the mac address of the destination in its table. Several questions asks about "what subnet is this one, what is the last IP, etc." yet gives no example of the interface output except when you show the answer. The other questions were good, but are all in Daniel dump.
