CCENT And CCNA Flash Card Practice Exam:
Hexadecimal Conversions
It's nice to share, so share and Google +1 this exam! :)
Let's get the ol' Bulldog Brain clicking with this flash card practice exam -- and there's a very special, all-new announcement in bold below the questions and answers.
Be sure to read it. Let's get started with today's practice exam!
Today's questions deal with an often-overlooked subject on the CCNA and CCENT exams. Given the hex values below, convert them to decimal.
a2
B4
3F
1Ac
2F1
We'll go through the answers, step-by-step, right after this:
Sign up for any of my paid CCNA or CCNP courses on Udemy from July 21 - 31, and I'll give you a free pass to my CCNA Security Video Boot Camp!

See you there! Right now, let's get to today's answers. A couple of hex reminders....
The letters "A" through "F" represent the decimals 10 - 15, respectively.
The case of the letters doesn't matter. An upper case "A" and a lower case "a" both represent "10".
That said, let's work through each of these exercises:
The hex value a2 means we have 10 ("a") units of 16, and 2 units of 1. 160 + 2 = 162.
B4 gives us 11 ("b") units of 16 and 4 units of 1. 176 + 4 = 180.
3F represents 3 units of 16 and 15 units of 1. 48 + 15 = 63.
1Ac converts to 1 unit of 256, 10 units of 16, and 12 units of 1. 256 + 160 + 12 = 428.
Finally, 2F1 gives us 2 units of 256, 15 units of 16, and 1 unit of 1. 512 + 240 + 1 = 753.
That's it! I'll see you later today with two new videos, and as always, I'll see you on YouTube and Udemy!

Is the CCNA exam changing again do you know?
Also, keep up the great work.
Many Thanks

No changes have been announced and it'll likely be at least 2 more years before they do change it. I just want to assure students of the free updates. : )
