If you want to prepare for the CCNP exam, you can use the most current version of the textbook for your studies. Technology is evolving rapidly, so your use of an older version of the material may no longer be applicable to the current exam. Currently, Cisco's CCNP exam materials are in English. If you have difficulty with English, we recommend that you find some reference materials in Chinese to help you understand and master the exam content during your study. You can also practice reading and comprehending English materials during your study to improve your English.
