Recommended Study Resources
The main resource for study will be either the IPS v7 class material from Cisco, or the CCNP Security IPS 642-627 Official Cert Guide. They both cover the wide range of topics required for the exam. You will also need access to a live 4200 appliance that is running the 7.x code. Version 6.x or older will not be sufficient, due to the missing features and different IDM interface that is used on that previous software version.
Cisco’s online documentation is another valuable resource that can be used for digging deeper into the details of specific item you may be studying.
