 What I liked in “CCNA Voice 640-461 Official Cert Guide”

As many folks might tell you, if you are preparing for a CCNA level exam, go with Cisco Press books first. This piece of advice helped me understand networking from Cisco’s point of view. And that’s what you basically need to pass the exam. Besides, in my past CCNP studies, I remember that some questions that appeared on the exam also were mentioned in some Q&A sections!

Here is what I liked in “CCNA Voice 640-461 Official Cert Guide”:

  • The book does well in introducing voice in general, and voice over IP in particular. For most IP engineers, the transition to a VOIP world is a bit harder than those who worked with telecom gear in the past. This Cisco book facilitates the transition. It’s an excellent exam guide and can be used as a reference later on.
  • Almost all areas of Unified Communications have been introduced, except maybe for Telepresence. I only knew about CME and Call Manager (I learned later that the new terminology is Cisco Unified Communications Manager and Cisco Unified Communications Manager Express).
  • I found answers to some confusing concepts such Publisher and Subscriber, Presence,… I work with CUCM on almost a daily basis, and the cert guide cleared many things out in my head. I was able to connect the dots.
  • Jeremy as an author. It’s just that. When I first thought that I’m going to read seriously about VoIP and Unified Communications, I thought that voice would not be as fun as routing&switching. I was wrong! From the moment I found the name “Jeremy Ciaora”, I quickly concluded that it will be fun. I loved the Jeremy touch! If you are used to watch Jeremy teaching Cisco material, you will notice his passion about the subject across the lines.
  • Both “Do You Know This Already?” and “Q&A” sections are my favourite parts of each chapter.

I found “CCNA Voice 640-461 Official Cert Guide” to be informative in the area of Unified Communications, for a beginner like me. The diagrams and screenshots were helpful to map theory to practice. I highly recommend it to anyone thinking about the CCNA Voice “ICOMM” exam or simply working with voice in his day-to-day job.
