Designing Scalable and Resilient Networks: Need Advice for CCDE Exam

[Lab4CCIE]

I am currently preparing for the CCDE (Cisco Certified Design Expert) exam and I have encountered a challenge regarding the design of scalable and resilient networks. I understand the importance of these factors in network architecture, but I am seeking expert advice and real-world insights to enhance my understanding.

Specifically, I would like to discuss the following:

1. Best practices for designing a network that can scale efficiently to accommodate future growth without compromising performance.
2. Strategies for building network resilience and redundancy to ensure high availability and fault tolerance.
3. Techniques for optimizing network design to minimize latency and improve overall performance.
4. Considerations for integrating security measures into the network design, without sacrificing scalability or performance.
5. How to evaluate and select the appropriate routing protocols and technologies based on the specific requirements of a network design.

I would greatly appreciate any advice, practical examples, or recommended resources that can help me strengthen my knowledge and skills in designing scalable and resilient networks for the CCDE exam. Thank you in advance for your assistance!
