I Am a CCNA Data Center Bad Ass!

May 3, 2013 at 9:13 pm



I cleared the CCNA Data Center this week. It felt a little silly since I have been teaching NP level classes for Data Center for a long time now.

Thank you so much to 1ExamAMonth.com  ! I purchased their practice exam for the 640-911 DCICN exam and that was the only resource I needed. This is like CCNA with some Data Center basics thrown in. It was strange to see questions about hubs and Token Ring in a Data Center exam, perhaps some technical editor was asleep at the wheel when those questions made the cut.

CCIE Security Version 4 – The ASAs

May 2, 2013 at 3:33 pm

My study of the ASAs is drawing to a close. My plan was to do a lot of posts regarding these studies, but as you might guess, it is too difficult to study and do a lot of blogging on the process when you are dealing with a fixed amount of time for actual study. Here is a recap of prep required on the ASAs.


The Hardware:

  • Cisco ASA 5500 and 5500-X Series Adaptive Security Appliances
    • Cisco ASA 5500 Series Adaptive Security Appliances OS Software Versions 8.2x, 8.4x, 8.6x
  • We can expect 4 of these devices

The Study Checklist:

  • Initializing the Basic Cisco ASA Firewall (IP Address, Mask, Default Route, etc.)
  • Understanding Security Levels (Same Security Interface)
  • Understanding Single vs. Multimode
  • Understanding Firewall vs. Transparent Mode
  • Understanding Multiple Security Contexts

ASA Basic Interface Configurations

April 18, 2013 at 9:03 pm

I am off and running – wohoo! For today’s reading, I enjoyed the appropriate sections of the ASA All In One text from Cisco Press.


For lab work – I read the CCNP Security Lab Workbook from ACIT.in. I then created my own lab allowing me to practice a similar set of exercises in GNS3.


In this first objective  – we just need to be able to FLY through the basic configurations on an ASA interface. Remember, these interfaces possess names and security levels. Remember also that we are going to ping from the ASA to verify connectivity. We cannot, be default, ping through the ASA.

GNS3 – Its Not Just For Routers Anymore

April 17, 2013 at 8:28 pm

I have never been that big a fan of GNS3/Dynamips. I mean, I will use it in a pinch, like flying across the country and writing an article that requires I have access to the CLI, but that is about it.

Now – that is going to change a bit. With the GNS3/PEMU platform able to emulate the Adaptive Security Appliance (ASA) from Cisco Systems, I can use it for a huge chunk of my CCIE Security Version 4 lab prep.

In order to quickly get up to speed with the latest version of these technologies, I turned to the Keith Barker created series at CBTNugget.com. Yes, that’s right, he did an entire series on getting the most out of GNS3. I did not watch the entire thing – just enough to get my ASAs up and running for practice.

Since my Hands On Practice will begin with the ASAs, I will be using this emulator platform for initial preparation. Of course I will detail exactly what I am doing here at the blog!
