OCSA certification exam attests and formally certifies that the successful candidate has vendor-neutral conceptual knowledge of the major domains of networking practices that support the theory and practice of Software Defined Networking (SDN). It presupposes foundational knowledge in computer networking practices, and will validate conceptual knowledge in how those computer networking foundations are affected in an SDN environment. It is an entry-level certification examination for technical professionals asserting concept-level mastery of the domain of SDN.

Rajan has great enthusiasm to teach and very depth knowledge of cloud technologies. Even in my group, some were from different technological background and they moved to cloud and Dockerfield with in 3-4 months. It was an amazing experience learning with Rajan and will always appreciate his deep cloud knowledge. I am sure that his students will move towards bright future with Rajan’s guidance. One more very big benefit with Rathinam Trainers is whenever they start a new batch, they invite all old students, who has done the course, to participate in the new batch. Thank you very much Rathinam Trainers for your guidance. I achieved my CKA certification in only 3 months.

Rajan is a wonderfully engaging trainer, very easy to listen to and the course he provides is always the right mix of theory, practical demonstration and anecdotes. Responds professionally to challenging students. Listens and provides a mature, respectful response. Demonstrates patience and respectful guidance when interacting with students. My experience with Rajan and his bright team made me in less than six months a great competitor in the world of Technology.

I was looking for training on advance SDN. I came to know about Rajan from ONF website. He suggested me to start with python and then go for SDN training.Rajan's has an in-depth knowledge on python and Advanced SDN. I really enjoyed both courses very much and never missed his single class. Rajan's teaching style is really excellent and have great patient of explaining thing in a detailed manner. Other Than SDN theory, practical session on SDN was really awesome. Because of his coaching I could pass OCSE-111 exam today (Thank you Rajan). When time permits, I will join other courses of my interest.
