You want to get your first (or next) Cisco certification, but do you have a specific preparation strategy, or are you just winging it? If you do have a structured framework you’re confidently executing against, congratulations! If not, allow me to share my seven-step framework for Cisco exam preparation.
Yet another new topic on the new CCNA R/S v3 exam is BPDUGuard, which is an enhancement to Spanning Tree Protocol (STP) available on our Cisco Catalyst switches. Specifically, BPDUGuard can help prevent a Layer 2 topological loop by placing a port configured for PortFast into an Error-Disabled state if that port receives a Bridge Protocol Data Unit (BPDU).
One of the new topics on the new CCNA R/S v3 exam is Quality of Service (QoS). Having taught QoS for many years, I’ve noticed that one of the topics students find most challenging is QoS Traffic Markings.
You’ve earned your certifications. Maybe you have a college degree, and hopefully some technical experience. Now, it’s time to sell yourself to a prospective employer. We all know first impressions matter, and when it comes to the job seeker, that first impression is often in the form of a resume.
When you’re reviewing the list of topics on the new CCNA R/S version 3 exam, one topic that’s sure to stand out is the APIC-EM Path Trace ACL Analysis Tool. That’s a very long name for a very new feature, and this video demonstrates it for you. Specifically, you’ll see how we can have the APIC-EM discover a network topology and then synthetically predict how traffic will flow (or be blocked) as it travels through a network.
The recently announced CCNA R/S version 3 includes a collection of topics falling under the category of Network Programmability. The underlying technology here is Software Defined Network (SDN), which allows network device configurations to be orchestrated through software applications. Basically, instead of accessing a router or switch command line to enter traditional Cisco IOS commands, we can write a program (typically written in the Python programming language) to make changes to one or more devices. So, the purpose of this blog post is for you to learn the theory and architecture behind SDN.
A Wide Area Network (WAN) is a network with geographically separate locations, and these locations can be interconnected in a variety of topologies. This video shows you the three WAN topologies you need to know for the CCNA R/S version 3 exam.
The new CCNA R/S version 3 exam requires you to know how to configure static routing, for both IPv4 and IPv6 networks.
There are lots of things that I intend to get around to, sooner or later. One day, I’m going to clean out a bunch of old clothes from my closet. One day, I’m going to clean out my garage, and get it organized. The sobering fact, however, is I’ve had these intentions for a LONG time, and I’ve done nothing about them. If I were truly committed to getting these things done, I would put them on my calendar.

For me, the addition of QoS to the list of topic areas for the new CCNA R&S version 3 exam was a great thing. The reason is, QoS is my absolute favorite Cisco topic. So, I couldn’t wait to start recording the QoS portion of my CCNA R&S v3 Complete Video Course.
In fact, I recently shot this video on two of the most misunderstood QoS topics, Policing and Shaping. I thought this video could help you, whether you’re studying the Routing and Switching track or the Collaboration track.
