A Free and Hands-On Approach to Learning Kubernetes

November 14, 2018 at 10:03 pm


Containers running on a cluster (Kubernetes) has become the rage for application deployment. In the CBT Nuggets course I am working on right now (CCIE RS Evolving Technologies), I teach you all about containers and Kubernetes.

If you already know all about containers and want to get your hands on Kubernetes – there is an excellent (and free) interactive course here:


I did not have time to go through the whole thing – but I certainly liked what I did see.

Seven New Courses in Routing and Switching Coming from CBT Nuggets

Routing and Switching


I was thrilled to be tasked with creating new Nuggets on the topic of Enterprise Routing and Switching for Juniper networks. I quickly decided on two important approaches for this new training. First, I decided to break the topic up into seven courses so that I could really go into great detail. Second, I decided to separate these Nuggets clearly on theory, then Juniper specific stuff. This will be great for Cisco, Arista, HP, and other students that want to learn these important technologies, but could care very little for how specifics are carried out on Juniper gear.

The New Routing and Switching Courses:

Here is the breakdown of the new courses:

  • JNCIS-ENT(JN0-343)- Layer 2
  • JNCIS-ENT(JN0-343)- Layer 2 Security
  • JNCIS-ENT(JN0-343)- OSPF
  • JNCIS-ENT(JN0-343)- IS-IS
  • JNCIS-ENT(JN0-343)- BGP
  • JNCIS-ENT(JN0-343)- Protocol Independent Routing; Tunnels
  • JNCIS-ENT(JN0-343)- High Availability

So have you been longing for more training in some of these areas??? IS-IS perhaps??? These courses are really going to blow you away in their level of coverage, and overall approach.

The First Course – Layer 2:

What minimum topics list will we cover in the exciting first course on Layer 2 technologies? Check it out:

  • Identify the concepts, operation, and functionality of Layer 2 switching
  • Identify the concepts, benefits, and functionality of VLANs
  • Demonstrate knowledge of how to configure, monitor and troubleshoot Layer 2 switching and VLANs
  • Identify the concepts, benefits, operation, and functionality of the Spanning Tree Protocol
  • Demonstrate knowledge of how to configure and monitor STP and RSTP

Don’t miss this incredible opportunity to boost your knowledge of core routing and switching topics!

WiFi Speeds Starting To Scream

February 7, 2015 at 5:12 pm

wifi-icon-1004152910802.11ac devices that we saw in 2014 were pre-standard for the most part. 2015 features Wave 2 devices that should provide even better performance.

What is next for the rapidly evolving world of WiFi? 802.11ax will be here soon to provide speeds initially thought impossible. We should see devices in 2016, with the official ratification coming in about 2019.

How does 802.11ac work its magic? For starters, it operates in the far less crowded 5 GHZ band. This means we experience far less interference. The new Wave 2 devices feature MU-MIMO (multi-user multiple-input/multiple-output) technology permitting multiple spatial streams to multiple clients simultaneously.

Enjoy your unplugged experience!
