CCDA books?

matl

Hi,

I want to pursue the CCDA cert. CiscoPress has two books for the exam:

CCDA Self-Study: Designing for Cisco Internetwork Solutions (DESGN) 640-861

CCDA(R) Exam Certification Guide (CCDA Self-Study, 640-861)

Wich one is the best to pass the exam? Or do i need to read both?

Also do i need to buy some routers or switchs to practice and pass the exam?

Thanks.
