CCDA (Design Associate) Certification
Cisco CCDA validates the knowledge required to design a Cisco converged network. With a CCDA certification, a network professional demonstrates the skills required to design routed and switched network infrastructures and services involving LAN, WAN, and broadband access for businesses and organizations. Thus the CCDA is aimed at network design engineers and technicians involved in establishing network environments with an understanding of network design principles. The CCDA curriculum includes designing basic campus, data centre, security, voice, and wireless networks. CCDA certification opens the path to multiple higher level certifications, ranging up to the industry-leading CCAr.
The Certification Process
In order to obtain CCDA certification candidates are required to pass either one exam only, this exam is arranged separately from any training courses offered, further information on this exam can be seen by clicking on the title.

Official Cisco Materials
Cisco provides a large amount of online materials, some of which is available through the certification pages themselves. An excellent starting point is to look at the exam content available on the exam page as well as a PDF that provides the exam guidelines. It should be noted that this certification assumes some knowledge of routing and switching technologies, as well as some areas of voice and security. Thus if you qualify for this certification with a CCENT then it may be wise to ensure that you have adequate experience and knowledge relating to some areas of the ICDN2 exam and CCNA Routing and Switching in general.
The syllabus for the CCDA certification in its entirety can be found here.
Cisco hosts forums for those taking their certifications in the form of Study Groups, allowing for the discussion of any topics relating to CCDA and other certifications.

Reviewers also tend to indicate that the content is of sufficient depth to be used as a reference guide for some concepts.
Designing for Cisco Internetwork Solutions (DESGN) Foundation Learning Guide This book is designed for a rather different purpose to the cert guide. This book aims to provide the technical knowledge, rather than exam specific learning and assumes a lower level of background knowledge and experience. This book does receive positive reviews although it does usually need to be combined with more exam specific preparation as this particular series of books is more focused on providing the technical knowledge that underpins the certification.
Cisco CCDA Simplified This text receives positive reviews due to its clear outline as well as being well suited for those who are less familiar with network design in addition to voice, video, security and any other elements considered in this certification. There are also end of chapter tests that are similar to those included in the official Cisco tests. It should be noted that this particular book does not contain and practice labs and as such some other resources may be needed to prepare for the certification exam.
The Techexams.net forum is one of the most active covering Cisco and other certifications, there is a great deal of detailed information related to either specific technical details or the certification as a whole. It may be worth looking at some of the sections other than CCDA as this certification covers material from a range of other Cisco certifications.
CBT Nuggets have a series of instructional videos for this certification, with around 7 hours of content. This particular course does not include either a test lab, due to the theoretical nature of the exam, or any practice exams; this said it could still be a useful additional learning tool.
