CCNP ENARSI 300-410 & CCNP ENSLD 300-420 by Arash Deljoo Course

Editorial Take

This dual-exam CCNP course by Arash Deljoo is a powerhouse for network professionals aiming to validate advanced skills in routing and network design. Covering both ENARSI 300-410 and ENSLD 300-420, it delivers rigorous, exam-focused content ideal for certification candidates and working engineers alike.

Standout Strengths

• Comprehensive Exam Coverage: The course meticulously follows the official Cisco blueprints for both ENARSI and ENSLD. Every exam objective is addressed with precision, making it a reliable single source for certification prep.
• Instructor Expertise: Arash Deljoo demonstrates deep command of routing protocols and network theory. His explanations are methodical, reducing complex topics like BGP path selection into digestible segments with real-world context.
• Massive Content Volume: With over 110 hours of video, learners gain unparalleled depth in EIGRP, OSPFv2/v3, BGP, and route redistribution. This breadth supports both exam readiness and long-term skill retention.
• Design-Focused ENSLD Module: The ENSLD sections emphasize scalable network architecture, including IS-IS and BGP design patterns. This elevates the course beyond configuration into strategic planning, a rare find in online training.
• Clear Progression Structure: Topics are sequenced logically from IPv4/IPv6 review to advanced MPLS and VRF implementations. This scaffolding helps learners build knowledge incrementally without gaps.
• Practical Routing Emphasis: Real-world scenarios like route maps, conditional forwarding, and redistribution are explained with configuration examples. This bridges theory and implementation, enhancing job readiness.

Honest Limitations

• Pacing May Overwhelm Beginners: Despite 'All Levels' labeling, the course assumes strong foundational knowledge. Newcomers may struggle without prior CCNA-level experience or hands-on lab exposure.
• Limited Hands-On Labs: While concepts are well-explained, the course lacks integrated lab environments. Learners must set up their own GNS3 or EVE-NG labs to fully benefit from the content.
• Length Can Be Daunting: At over 110 hours, completing the course requires serious commitment. Learners may benefit from focusing on specific modules aligned with their exam or job goals.
• Minimal Assessment Tools: The course lacks quizzes, practice exams, or progress checks. Self-assessment relies on external resources, which could hinder retention for some students.

How to Get the Most Out of It

• Study cadence: Dedicate 6–8 hours per week over 4–5 months to fully absorb content without burnout. Prioritize modules based on exam focus or job relevance.
• Parallel project: Build a virtual lab using Cisco IOS or CML to replicate configurations demonstrated. Hands-on practice reinforces theoretical knowledge and builds confidence.
• Note-taking: Use structured note templates for each protocol (EIGRP, OSPF, BGP) to capture key commands, metrics, and design considerations for quick review.
• Community: Join CCNP-focused forums or Discord groups to discuss challenges, share lab setups, and clarify doubts with peers also preparing for certification.
• Practice: After each module, simulate real-world scenarios like multi-AS BGP peering or OSPF area design to test implementation skills and troubleshooting ability.
• Consistency: Maintain a regular schedule even with short daily sessions. Spaced repetition improves long-term retention of complex routing concepts and configurations.

Supplementary Resources

• Book: Pair with 'CCNP Enterprise ENARSI Official Cert Guide' by Patrick Grafton for aligned reading and practice questions to reinforce learning.
• Tool: Use GNS3 or Cisco Modeling Labs (CML) to create scalable network topologies and practice advanced routing scenarios covered in the course.
• Follow-up: Consider pursuing CCIE Enterprise Infrastructure for deeper expertise, as this course lays strong groundwork for that path.
• Reference: Bookmark Cisco’s official documentation for BGP and OSPF to cross-reference configurations and validate best practices during lab work.

Common Pitfalls

• Pitfall: Skipping IPv4/IPv6 review sections can lead to gaps in understanding subnetting and addressing schemes critical for advanced routing topics.
• Pitfall: Ignoring route redistribution labs may result in weak troubleshooting skills when integrating different routing protocols in production networks.
• Pitfall: Overlooking VRF and MPLS Layer 3 VPN concepts limits readiness for service provider and enterprise multi-tenant environments.

Time & Money ROI

• Time: Expect 3–5 months of consistent study to complete both tracks. The investment pays off in certification success and enhanced technical credibility.
• Cost-to-value: Despite being paid, the course offers exceptional value given its depth and dual-exam coverage, often exceeding more expensive bootcamps.
• Certificate: The completion certificate supports professional development goals, though the real value lies in passing Cisco’s official CCNP exams.
• Alternative: Free YouTube content lacks structure and depth; this course’s organization justifies its cost for serious certification candidates.

Editorial Verdict

This CCNP course by Arash Deljoo stands out as one of the most thorough and technically accurate resources available on Udemy for enterprise networking professionals. Its dual focus on ENARSI and ENSLD ensures learners gain both operational and design-level expertise, covering everything from EIGRP neighbor relationships to BGP route filtering and MPLS-based VPNs. The instructor’s clear delivery, combined with extensive content duration, makes it ideal for those preparing for certification or seeking to advance in network engineering roles. While the course assumes prior knowledge and lacks built-in labs, its structured approach and real-world relevance compensate for these limitations.

For motivated learners willing to pair the lectures with hands-on practice, this course delivers exceptional return on investment. It bridges the gap between foundational networking and expert-level implementation, particularly in complex routing environments. The depth of BGP and OSPF coverage alone justifies the time commitment, and the inclusion of design principles from ENSLD adds strategic value often missing in technical courses. We strongly recommend it to network administrators, engineers, and aspiring architects aiming to master Cisco’s CCNP Enterprise track. Just be prepared to supplement with lab environments and external assessments to maximize learning outcomes.
