2.  Convert the hex value A76 to decimal.

And now... the answers!

1.   "D".  By default, switches create more collision domains than hubs.  The term microsegmentation refers to the "one switch port, one collision domain" situation present on a switch.

You'll still have one giant broadcast domain unless you create VLANs on your switch.


2.   We have 10 units of 256, 7 units of 16, and 6 units of 1.

2560 + 112 + 6 =  2678


3.  "B".  With a standard ACL, you actually can't specify a destination IP address, even if you want to!

The extended ACL requires you to set both a source and destination IP address.


That's it for now -- a new practice exam right here on Tuesday!  See you then!

Hi Chris, good questions. In reference to your answer for question 1, should that be that we will still have one giant broadcast domain unless we create vlans?

Absolutely! Hopefully this will teach me not to edit on the run with no decaf. :) Thanks, Adam!
