Networking certifications for engineers who keep infrastructure running

Yes - Cisco CCNA remains the most recognised networking certification globally and is required or preferred on the majority of network engineer job descriptions. The 2020 CCNA redesign merged multiple tracks into a single comprehensive exam covering networking fundamentals, automation, security and programmability. CCNA holders earn a median of $88,000.

CompTIA Network+ is faster and cheaper, and is the right choice if you want a vendor-neutral credential quickly or are in the early stages of an IT career. CCNA is harder, more expensive, but carries significantly more weight for networking roles specifically. If networking is your intended career, go for CCNA. If you want a general foundation while deciding your direction, Network+ first.

CompTIA Linux+ covers Linux administration, scripting, shell commands, system management, security and troubleshooting - all at a vendor-neutral level applicable to any Linux distribution. It is most valuable for system administrators, DevOps engineers starting their career, and anyone working with Linux-based infrastructure. It pairs well with CCNA or AWS certifications as a complementary credential.
