Cisco DevNet Certifications: Programming and Automation for Network Engineers

What is this page about?

A guide to Cisco's DevNet certification track, created for network professionals adding programming and automation as job postings increasingly demand Python, Ansible, and REST API skills alongside routing knowledge. It covers DevNet Associate (200-901 DEVASC) and its Python requirement and platform coverage, DevNet Professional (350-901 DEVCOR) software-design depth, who should take which, free sandbox lab access, the network-specific Python libraries and YANG/NETCONF/RESTCONF depth actually tested, and network-automation career paths, salary ranges, and certification stacking.

   3 flagged issues verified: quotes attributed to Hank Preston (real Cisco Developer Advocate) and Jason Edelman (real Network to Code founder) had no locatable source and were de-attributed; a claimed cross-reference with 'compensation surveys from Network Collective and the NANOG community' (NANOG is not generally known for publishing compensation surveys) was softened to general salary-data framing.

   Before

   "The jump from DevNet Associate to Professional is larger than most candidates expect..." - Hank Preston, Cisco Developer Advocate [...] "NETCONF and YANG are the foundation of network programmability..." - Jason Edelman, founder of Network to Code and author of Network Programmability and Automation [...] Data from job postings on LinkedIn and Indeed, cross-referenced with compensation surveys from Network Collective and the NANOG community, represents ranges rather than guarantees.

   After

   The jump from DevNet Associate to Professional is larger than most candidates expect... [de-attributed] [...] NETCONF and YANG are widely considered the foundation of network programmability... [de-attributed] [...] Data from job postings on LinkedIn and Indeed, cross-referenced with general networking industry salary surveys, represents ranges rather than guarantees.

   Why: De-attributed two unverified quotes falsely credited to Hank Preston and Jason Edelman with no verifiable source, and softened a data-sourcing claim that misattributed compensation-survey data to Network Collective and NANOG (not generally known for publishing such surveys). Note: a second, separate unverified quote also credited to Hank Preston later in the same article was found during review but is outside this item's described scope and was left untouched.
