The main changes are:
There will only be one training and only one exam for the new CCNA certification. This course contains all the basic knowledge for all further certifications, but is no prerequisite.
With the CCNP certification you can choose your specialisation:
For every CCNP certification there is one basic exam and – depending on the specialisation – one additional exam.
If you have started working toward any current CCNP certification, keep going. In the new program, you’ll receive credit for work you’ve already completed in the current program.
