This course exceeded all my expectations. The instructor demonstrates incredibly deep knowledge of the subject and presents every topic with remarkable clarity and precision. What truly sets this course apart is the way complex concepts are broken down into simple, easy-to-understand explanations without ever oversimplifying the material. Each and every topic is covered thoroughly, with exceptional attention to detail. The explanations are structured, logical, and engaging, making it easy to follow along and build a strong understanding step by step. It’s clear that the instructor not only masters the subject but also genuinely cares about teaching and ensuring students fully grasp the material. The examples, practical insights, and clear demonstrations make learning both effective and enjoyable. I especially appreciate how no question feels unanswered, every concept is explained with patience and depth. I highly recommend this course to anyone looking for a comprehensive, well-structured, and expertly delivered learning experience. Truly one of the best courses I’ve taken!

By Antonio Sandoval on 7/17/2026

very conflicted as i write this review, ill try to keep this as short as possible so i will list issues one at a time. 1. seems like almost half of this course is re watching your CCNA course 2. repetitiveness almost to the point of overkill. 3. no clear sign if the course is going to be CCNA or CCNP related until you actually start watching the video, or sometimes even in the middle of the course cuts to one of your CCNA videos. i guess all of my complaints/feedback relates to the lack of clarity of whether this information is actually new material for the CCNP course. i will finish your course as i intend to use it as my main study material, and may change my rating when i am done, but it seems pretty evident that 150+ hours of material is simply just bulk and buffer of CCNA videos. In my opinion you should mention topics that would need to be understood and allow your students to make the decision of going back to study or not. i may or may not change my rating if and when i finish this course.

By Jasmine Osborne on 3/12/2026

Finished the entire course. It’s very long, but full of all the required details plus more for the CCNP ENCOR exam. The depth of the material is excellent, especially the way it bridges core networking concepts with the network automation skills needed in modern environments. Excellent main resource. I also like the way he draws, writes and describes many concepts and network topologies in depth in different ways, way beyond the book but crucial for understanding the concepts. Also shows how things work by showing the messages exchanged back and forth between the components and how devices operate in different modes and configurations. I also passed the exam also with a high score using his course as my main source + active recall

A really great course. I would say this is up there with INE. Really well explained, great demos and well thought out course. What I love about Arash is that you can tell he has a genuine and real passion for networking. If old school CBT Nuggets (Jeremy C) and INE got together this would be the result...excellent and deep material, well explained, thorough, but with real passion and a genuine love of the topics. I think this course will not only help you pass ENCOR but will also ignite a love of networking...which is key. There are too many hacks, quick videos, and people wanting to pass quickly! ENCOR and Cisco CCNP level exams are supposed to take time and designed to go deep, so great to see a course with 150 hours (which is what it takes) rather than 20 hours and missing out so many in-depth topics. Good job Arash.

By Atinc B. on 7/11/2025

I highly recommend taking this training. It has very detailed content, diving deep into nearly every key command you might encounter, with thorough explanations. The instructor demonstrates strong expertise in the topics covered. I didn’t find any issues with the language, though it might take a short time to get used to the accent. Instead of using a whiteboard or similar tools, the instructor opts for an old-school approach, using Notepad for explanations, and does so very effectively. For those familiar with CLI, this won’t be an issue. The pace of the training is somewhat slow, primarily due to the in-depth explanations and calm delivery style. It feels as though the training was recorded without any time constraints, which is both a strength and a drawback. I won’t elaborate on why it’s a strength, but to overcome the downside, you can watch certain sections at 1.5x speed (e.g., parts that revisit previously covered material) or even 2x speed (e.g., sections showing basic device configurations before lab exercises). There are plenty of lab exercises, which are definitely beneficial. This training will undoubtedly be valuable.

Thank You for your Excellent Course! Your teaching style is truly exceptional, and I found many of the topics beneficial and effectively explained. especially the technique of presenting a problem first and then using relevant features to resolve it , this approach was much easier to grasp complex concepts. The reviews of each topic and the emphasis on repeating important notes and presenting more information that covers in the ENCOR were so helpful, too. Overall, having such a comprehensive curriculum was fantastic! I have two suggestions that might make your course much better. First, Adding practical labs like the Quizzes or just add as resources would be immensely beneficial. two topology for each topic—one simple and one more complex for us,—where we can practice what we've learned. Sharing the answers as text would allow us to work through them independently and see our results.its much better than repeating your topology which explained in the videos Secondly, some of the theoretical topics, specially after the Fabric section and with wireless chapters too.when this topics are big part of the exam and all are new topics for someone study CCNP. you relied heavily on just reading from the official book. which is not good like other sections . It would be great if these chapters could be simplified or explained in a more accessible way. Once again, thank you so much for your excellent teaching and dedication.

By Okemo Hodge on 11/22/2024

Many thanks, Arash for this wonderful and mind-blowing course. Part of the course is from the CCNA that should be familiar to the student. Many more new topics were discussed. Those topics that were beyond the purview of the course, he said so. I have never seen an ENCOR course with so much information. When Arash is finished with us, we will be masters in Cisco networking. Watch the lessons in full screen mode because some of the fonts are so small. A word of advice, go through the course in the following order. CCNA, ENCOR, and ENARSI. If you go to the ENARSI after the CCNA, you will get confused.

By Hasan Bilici on 11/2/2024

I am currently studying Routing Protocols Fundamentals, and this ENCOR course has been by far the best I've encountered. I had already read the official book up to BGP, but I found some of the topics from the CCNA a bit difficult to remember and the book hard to understand. Fortunately, I came across this course, and it has been a game-changer. Although the course is lengthy, it covers everything you need to know in great detail. The hands-on labs and thorough explanations have made complex concepts much easier to grasp. I’ll be sure to update my review once I’ve completed the course.

By Sushim G. on 10/8/2024

Arash Deljoo is thoroughly knowledgeful instructor. Very clear with networking concepts. Very good delivery of topics in clear words and very detailed manner. Do not rush to finish the job, but cares for quality delivery. Best part about his teaching is he gives real knowledge means, even if he is selling CCNP course, for more and better understanding he adds CCNA video in it. And i have observed in CCNA video also he covers few additional knowledge info in some topics which are not part of the exam but as a network engineer it is necessary to understand , he do not hesitate to share extra knowledge in same cost. He is one of the best instructor for Cisco Related courses, which i have attended.

By Ivan Rusev on 3/19/2024

Ok let me start from the beginning here. I finished CCNA and I started CCNP I used Jeremys IT labs for the CCNA it was great I Pass. I started using Jeremys IT Labs for ENCOR but course is not finished. I had to find another course that matches or it is as good as Jeremys. I went and looked at 3 other video courses By Kevin Wallace ( Not good), By Pearson (Not good and expensive) and this course by Mr Arash(So far AMAZING). I am in the beginning of the course past Spanning tree, so this is what I can conclude so far. Jeremy from Jeremys IT Labs perhaps slightly better teaching techniques. However Mr. Arash also explains very well and in alot of detail, and right away I can tell Mr. Arash have a lot deeper knowledge, and probably a lot more experience than Jeremy and there are complex things that are explained in such a way that is alot easier to understand as a whole. The videos are long, very long but there is a lot of value in the course. This is a ENCOR course of very high quality and it is my main study material for the ENCOR. 2nd Update half way thru the course: Probably the best course you can find out there. Very Detailed and Long but it is worth every minute. 3d Update: Iam by the end of the course, what can I say.... 6 stars. It is incredible. I am so lucky I found this course. I am very Confident going for the Encore in a month or 2. 4th Update: I passed the ENCOR !!! This course was my main study guide, not the only study guide but my main. Now I am going for the ENARSI. I allready own Mr. Araj ENARSI course I feel very confident.
