To get everyone caught up (including me!), I've reposted the last two CCNA and CCENT videos I created for you -- and they're followed by a new practice exam.  Let's get to work!

Can your heart stand the SHOCKING FACTS.... behind THE ANSWERS TO THESE QUESTIONS?

I sure hope so, 'cause here they are!

1.  The route type with the lowest AD is the EIGRP internal route (90).

There's a tie after that, because OSPF internal and external routes both have an AD of 110.

Highest of all is the EIGRP external route, checking in with an AD of 170.

2.   "3ab" in hex gives us 3 units of 256, 10 units of 16, and 11 units of 1.

768 +  160 + 11  = 939.

3.   The binary string 00110011 converts to 51 in decimal.

That's it for today!  See you Wednesday with more!

More what, you ask?  Show up and find out!

I am going to have to start coming here more often. These little tid-bits are going to add up and solidify.
