My CCNA will expired at July 2010, I want to take the CCNP, if I passed one of the four module, is it gonna extended automatically for three years and I want to take the next module after three years, is it possible?
And how much the price for CCNA Security and CCDA ?
Yes, when you pass any of the CCNP exams, your CCNA will be extended for 3 years from the data that you pass. You will have 3 years from the date you pass your first CCNP exam to complete the remaining exams as each exam is valid for 3 years.
640-553 is $250 US
640-863 is $150 US
Hope this helps.
