How to Pass the CCDE Written Exam: A Complete Guide

The Cisco Certified Design Expert (CCDE) written exam is one of the most challenging certification tests for network design professionals. Achieving CCDE certification proves your expertise in designing complex infrastructure solutions. This guide will help you understand the exam structure, preparation strategies, and valuable resources to pass the CCDE written exam successfully.

Understanding the CCDE Written Exam

The CCDE written exam assesses candidates on advanced network design principles, covering various topics such as:

Routing protocols (OSPF, BGP, EIGRP, and IS-IS)
Network security and design considerations
Quality of Service (QoS) and network resilience
Data center, enterprise, and service provider architectures
Network virtualization and automation

To pass the CCDE written exam, candidates must demonstrate deep technical knowledge and the ability to apply design principles in real-world scenarios.

Exam Details and Requirements

Before preparing, you should understand the exam details:

Exam Code: 400-007
Duration: 120 minutes
Number of Questions: Around 90-110
Question Format: Multiple-choice and scenario-based
Passing Score: Varies but typically around 800-850/1000

The exam is a prerequisite for the CCDE practical exam, so it’s essential to have a solid understanding of networking concepts.

Preparation Strategies for the CCDE Written Exam

Review Cisco’s Official Exam Topics
Visit the official Cisco website and download the CCDE written exam blueprint. This will help you understand the areas you need to focus on.
Utilize Cisco Press Books and Study Guides
Books such as CCDE Study Guide by Marwan Al-Shawi and Optimal Routing Design by Russ White and Alvaro Retana provide valuable insights.
Enroll in Training Courses
Cisco’s Learning Network offers training courses and webinars that provide deep dives into complex topics. You can also explore third-party training providers like INE and Orhan Ergun’s CCDE training programs.
Join Study Groups and Forums
Engaging with the networking community can be incredibly beneficial. Platforms like Cisco Learning Network, Reddit, and specialized LinkedIn groups offer valuable discussion opportunities.
Practice with Real-World Scenarios
Hands-on experience is crucial. Work on design case studies and apply network design principles in a lab environment. Consider using Cisco’s VIRL or GNS3 to simulate network architectures.
Take Practice Exams
Simulating the actual test environment helps improve time management and identify weak areas. Websites like Boson ExSim provide realistic practice tests.
Stay Updated with Industry Trends
Network design principles evolve with technology. Follow Cisco’s blogs, attend webinars, and read whitepapers to keep up with the latest advancements.
Create a Study Plan
Structure your preparation schedule by allocating time to each exam topic. Use a mix of reading, hands-on practice, and discussions to enhance learning.
Understand Design Best Practices
The CCDE written exam emphasizes best practices rather than configuration. Focus on high-level architectural decisions and trade-offs between different network designs.
Review RFCs and Whitepapers
Understanding industry standards is crucial for success. RFCs related to BGP, OSPF, and network security provide a strong foundation for design concepts.

Common Challenges and How to Overcome Them

Time Management: The exam is time-sensitive, so practicing under exam conditions is essential.
Understanding Scenarios: The CCDE written exam focuses on real-world problems, so develop a mindset for solving complex design issues.
Keeping Up with Industry Trends: Cisco updates its exam topics periodically, so stay updated with the latest networking trends and best practices.
Overwhelming Study Material: The CCDE exam covers a vast syllabus. Focus on high-impact topics and avoid getting lost in unnecessary details.
Building Practical Experience: Theoretical knowledge alone won’t help; hands-on experience in designing networks is crucial.
Balancing Work and Study: Many candidates have full-time jobs, making it difficult to allocate study time. A well-structured study plan is essential for balancing both.

Additional Study Resources

Cisco’s Learning Network: Offers official CCDE resources and study groups.
Cisco Live Sessions: Provides technical sessions from Cisco experts.
Networking Blogs and Podcasts: Listening to industry professionals can give insights into real-world network design challenges.
