The first certification is the ONF-Certified SDN Associate certification (OCSA). The aim of this certification is to validate knowledge of foundational concepts in SDN. When released later this year, the test can be taken online, and will be helpful in validating the skills and knowledge of individuals working in the SDN professional ecosystem who are not involved in actual development and management of SDN (think product marketing professionals, sales and support professionals, entry-level engineers, etc.). The exam is in development and all SDN professionals are asked to validate the preliminary draft of the knowledge domains of this certification.

Certification

ONF-certified-associate Exam Title: ONF-Certified SDN Associate (OCSA-110) Exam Details: 40 questions in 60 minutes and a pass score of 70%. Full credit given for each correct answer, no partial credit, as all questions return a binary response (correct/incorrect). Exam Delivery: Delivered electronically via secure login, with attestation and affirmation of academic integrity by the candidate. Exam to be available in English and Simplified Chinese by Q4 2015. Credential Awarded: ONF Certified SDN Associate (OCSA) upon successful completion of the exam. Exam Purpose: This 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.

Prerequisite

In order to pass the ONF OCSA Exam, a foundational knowledge of computer networking is assumed, with specific familiarity with various conceptual models of networking (OSI, Internet, etc.) and technologies also required. No job experience is mandated, but your familiarity with all the knowledge domains of this certification is essential to succeed. Resources that would be helpful include publications on networking, as well as foundational certifications in networking from Cisco, Citrix, CompTIA, Juniper, or Microsoft, and materials freely available from Open Networking Foundation.
