A 4400 WLC is fine for CCNP.

K9 just means the WLC supports encryption.

Thank you so much for your fast reply. just one more question, do you think the following device is good for wireless CCNP ?

Cisco AIR-WLC2106-K9 V05 2100 Series Wireless Lan Controller
Craig BeckCommented:
2106 is OK too.  It'll do what you need for the CCNP but it usually costs more than a 4402.
