In many workplace they always encourage junior network engineers to
follow a Cisco certification path, either through the Routing and
Switching path or other important technology paths such as network
security and VoIP. I have been in this industry for more than a decade
and I firmly believe that in order to succeed in the networking
professional career one must earn relevant professional certifications.
Getting
your Cisco CCNA Certification is perfectly sufficient to start with;
don't be pushed into attempting your CCNP. After gaining experience in
the working environment, you will have a feel for if it's relevant for
you to have this next level up. If so, your experience will serve as the
background you need to master your CCNP - which is quite a hard
qualification to acquire - and mustn't be entered into casually.
Most
network administrators and engineers are going to spend a lot more time
troubleshooting than installing. That's just the way it is. And to
troubleshoot effectively, you've got to know what's going on at all
layers of the OSI model, not just layers 2 and 3.
As someone
who's done a lot of hiring and conducted a great many job interviews, I
can tell you that the ability to troubleshoot is the number one quality I
look for. That's why I tell CCNA and CCNP candidates that they've got
to get all the hands-on practice they can while I understand the
importance of theory, the only way to develop troubleshooting ability is
to work on the real deal. No simulator program
is going to teach you how to troubleshoot.
Additionally,
the only way to truly develop your troubleshooting abilities is to know
what's going on over the entire network, not just the routers and
switches. Troubleshooting always starts at Layer 1 if you don't find a
problem at the Physical layer, and everything's fine with your routers
and switches, how are you going to continue troubleshooting if you don't
know what the next steps are as data moves closer to the end user?
There
are several training options available for CCNA Exams preparation, such
as self-study via books, instructor based training (boot camp style),
video training, simulation exams etc. From my own experience when
studying for my Cisco exams, and also from discussions with other
certified colleagues, one of the best ways to study for CCNA is using a
CCNA Training package. Especially when you combine a video training
package with exam practice questions, you will have a complete
preparation method for passing your exam. A video training package
includes DVD quality videos with a real instructor teaching the course
and guiding you through the exam objectives to help you pass.
