CCNA, CCNP, Data Center & AI Infrastructure certifications

About Cisco

Cisco runs one of the largest and longest-running vendor certification programs in IT, spanning associate-level CCNA through professional-level CCNP and expert-level CCIE tracks across networking, security, data center, collaboration, and automation. In 2026 Cisco extended its data center track into AI infrastructure with the Cisco Certified Specialist - Data Center AI Infrastructure credential: exam 300-640 (Implementing Cisco Data Center AI Infrastructure), a 90-minute, ~83%-to-pass exam first offered February 9, 2026 that also counts as one of the required exams toward CCNP Data Center. It tests designing, implementing, operating, and troubleshooting AI-ready infrastructure across network, compute, storage, and orchestration.

Why get certified

CCNA remains one of the most recognized entry points into networking careers, and CCNP-level Cisco certifications routinely appear as hard requirements in network engineer and data center job postings, particularly at organizations running Cisco's dominant share of enterprise networking hardware. The new AI Infrastructure specialization tracks a real shift in enterprise budgets toward AI-ready data centers, giving early certification holders a credential for a skill set still in short supply.
