With over 87 hours of content, it dives deep into both foundational and advanced topics required for the ENSLD certification. ### Standout Strengths - Comprehensive IPv4/IPv6 Coverage: The course begins with robust modules on IPv4 and IPv6 design, offering practical insights into subnetting, addressing schemes, and transition strategies. Learners gain hands-on understanding of scalable IP architectures. - In-Depth Routing Protocol Analysis: EIGRP, IS-IS, OSPF, and BGP are explored with technical precision. Each protocol is broken down into design principles, optimization techniques, and real-world deployment scenarios for enterprise environments. - Enterprise LAN & Campus Design: The course excels in explaining hierarchical network models, redundancy mechanisms, and Layer 2/Layer 3 design trade-offs. It prepares learners for complex campus network implementations. - SD-Access and SD-WAN Expertise: Cisco’s modern SDN solutions are covered in detail. The SD-Access module explains fabric design, policy control, and integration with existing infrastructure, making it highly relevant for current network trends. - Automation and API Integration: Though brief, the automation section introduces essential API concepts and programmability in network design. It bridges traditional networking with modern DevNet practices. - Exam Alignment and Structure: The syllabus mirrors the ENSLD 300-420 blueprint exactly. This makes it an ideal prep resource, ensuring no topic is missed and learners are fully exam-ready. ### Honest Limitations - Limited Hands-On Labs: While theory is strong, the course lacks integrated lab exercises or simulations. Learners must set up their own environments to practice configurations and validate designs. - Assumes Foundational Knowledge: Some sections, especially on BGP and IS-IS, assume prior familiarity with routing concepts. Beginners may need supplemental study to keep up with the pace. - Minimal Student Interaction: As a Udemy course, it offers no live Q&A or peer discussion forums. Learners must rely on comments or external communities for clarification. ### How to Get the Most Out of It - Study cadence: Break the course into weekly segments. Aim for 5–7 hours per week to maintain consistency without burnout. Focus on one module at a time for deeper retention. - Parallel project: Design a fictional enterprise network as you progress. Apply each concept—IPv6 addressing, OSPF areas, SD-WAN policies—to reinforce learning through practical application. - Note-taking: Use digital or physical notebooks to document key design principles, command syntax, and topology diagrams. This aids in exam review and long-term retention. - Community: Join networking forums like Reddit’s r/networking or Cisco Learning Network. Engage with peers to discuss complex topics and share study strategies. - Practice: Use GNS3 or Packet Tracer to simulate network designs taught in the course. Hands-on practice ensures theoretical knowledge translates into real-world skills. - Consistency: Schedule fixed study times and treat the course like a certification track. Regular, focused sessions yield better results than sporadic binge-watching. ### Supplementary Resources - Book: Pair this course with 'CCNP and CCIE Enterprise Core ENSLD 300-420 Official Cert Guide' by Cisco Press for deeper theoretical context and practice questions. - Tool: Use Cisco Modeling Labs (CML) or EVE-NG to build and test the network topologies discussed in the course for realistic experience. - Follow-up: After completion, pursue the ENARSI course to master implementation and troubleshooting of the designs taught here. - Reference: Bookmark Cisco’s official design guides and whitepapers for up-to-date best practices on SD-WAN, multicast, and network automation. ### Common Pitfalls - Pitfall: Skipping foundational modules can lead to confusion later. Even experienced learners should review IPv4/IPv6 design basics to align with the instructor’s methodology. - Pitfall: Relying solely on video without hands-on practice limits skill transfer. Without lab work, design concepts remain abstract and harder to recall during exams. - Pitfall: Underestimating the exam’s depth. The ENSLD test requires detailed design decisions—learners must go beyond memorization and understand trade-offs. ### Time & Money ROI - Time: The 87-hour commitment is substantial but justified for certification prep. Completing it over 12–16 weeks ensures deep understanding without burnout. - Cost-to-value: Compared to formal training programs, this course offers exceptional value. The depth of content far exceeds typical paid courses on similar topics. - Certificate: The completion certificate adds credibility to your profile, especially when combined with Cisco certification milestones. - Alternative: Free YouTube content may cover fragments, but none match the structured, exam-aligned depth of this course for ENSLD preparation. ### Editorial Verdict This course stands as one of the most thorough and technically accurate resources available for mastering the Cisco ENSLD 300-420 exam. Arash Deljoo’s methodical teaching style, combined with a syllabus that mirrors the official exam blueprint, makes it an indispensable tool for network engineers. The depth of coverage on IPv6, OSPF, BGP, and modern SDN technologies ensures learners are not only exam-ready but also equipped for real-world design challenges. It fills a critical gap between theoretical knowledge and practical implementation in enterprise networking. While the course’s length and lack of interactive labs may pose challenges, these are outweighed by its comprehensive structure and alignment with industry standards. It is best suited for motivated learners with some networking background who are serious about advancing their careers. For those preparing for Cisco certifications or aiming to design scalable, secure enterprise networks, this course delivers exceptional return on investment. With supplemental lab practice and consistent study, it can serve as the cornerstone of a professional networking education path. ## How Complete Teaching of ENSLD 300-420 v1.1 by Arash Deljoo Compares | Course | Platform | Rating | Level | Duration | | --- | --- | --- | --- | --- | | Complete Teaching of ENSLD 300-420 v1.1 by Arash Deljoo | Udemy | 9.4/10 | All Levels | 87h 13m | | IBM IT Support Professional Certificate Course | Coursera | 9.9/10 | N/A | N/A | | The Pronunciation of American English Specialization Course | Coursera | 9.8/10 | N/A | N/A | | Go and C++: Programming in Two Successor Languages of C Specialization Course | Coursera | 9.8/10 | N/A | N/A | ## Who Should Take Complete Teaching of ENSLD 300-420 v1.1 by Arash Deljoo?
