A sequenced guide to the best certifications for network administrators — from Network+ and CCNA to CCNP Enterprise and vendor specialisms, with costs and renewal facts.
Network and computer systems administrators in the United States earned a median salary of $96,800 according to the Bureau of Labor Statistics (May 2024 data) — comfortably below the $112,333 average that US Cisco CCNA holders reported in the Skillsoft IT Skills and Salary Survey, and far below the $144,912 reported by CCNP Enterprise holders in the same survey. Averages are shaped by experience and location as much as by any credential, but the pattern behind them is real: in network administration, certifications map unusually cleanly onto pay bands and job tiers, because so much of the role is vendor-specific, testable, hands-on skill.
That makes the useful question not "which certification is best?" but "which certification is best at my current rung?" This guide sequences the field into four tiers — foundation, core, professional and specialist — and tells you what each one actually buys a network administrator. It stays on the network track throughout: if your role leans more towards servers and identity than switches and routing, the system administrator certification ladder is the better guide for you.
Almost every worthwhile networking credential slots into a recognisable hierarchy, and the two dominant vendors mirror each other:
Cisco removed formal prerequisites across its written exams in the February 2020 restructure, so nothing legally forces you up this ladder in order. Practically, though, each tier assumes the fluency of the one below it, and hiring managers read the tiers the same way. Cisco's Aug 2026 line-up also includes an entry rung below CCNA — the Cisco Certified Support Technician (CCST) Networking exam, US $125 via Certiport — but for anyone already working as an administrator it is usually a rung you have outgrown.
Best for: help desk and support staff moving into their first network admin role; admins who inherited the network and need the theory under their practice.
CompTIA Network+ (N10-009 as of August 2026) is the vendor-neutral statement that you understand how networks work anywhere: addressing and subnetting, routing and switching concepts, wireless, security fundamentals and troubleshooting method. The exam is up to 90 questions in 90 minutes, mixing multiple-choice with performance-based items, with a published passing score of 720 on CompTIA's 100–900 scale. US retail was $399 after CompTIA's June 2026 price rise (per its authorised resellers; regional pricing varies). It is valid for three years and renewed through CompTIA's CE programme with 30 CEUs — or automatically, by passing a higher CompTIA exam.
There are no enforced prerequisites; CompTIA recommends A+ plus nine to twelve months in a junior network support role. For a working administrator its main value is twofold: it fills conceptual gaps that on-the-job learning skips, and it satisfies the HR filters at organisations that ask for a certification without caring which vendor. What it will not do is prove you can configure anything — that proof starts at the next tier.
Best for: anyone administering networks day to day; the single certification most network admin postings name.
If a network administrator earns only one certification, the Cisco CCNA (exam 200-301, topics v1.1 since 20 August 2024) is the defensible choice. It tests configuration-level knowledge across routing, switching, IP services, wireless, security fundamentals and — since v1.1 — automation, cloud network management and generative AI awareness. One 120-minute exam, US $300 plus regional taxes, delivered at Pearson VUE centres or online via OnVUE. Cisco publishes neither a question count nor a passing score, so ignore the confident numbers circulating in forums. The certification is valid three years and renews via 30 continuing-education credits, re-passing an associate exam, or passing any professional-level exam.
Why it dominates: Cisco equipment and Cisco-trained thinking remain pervasive in enterprise networks, so the CCNA works as a lingua franca even at shops running other vendors. It is also the gateway credential — the entire professional tier (Tier 3) assumes it in spirit if not in rule.
Study for it like a practical exam, not a reading exam. A realistic pattern: an administrator with two years of switch-and-firewall exposure spends her evenings on labs, then runs a timed mock a month before booking; the score report shows routing protocols lagging behind everything else, so the final month goes there instead of into comfortable revision. Analysing practice results by domain — rather than re-running questions until the answers are memorised — is the difference between a diagnostic and a comfort blanket. The free CCNA 200-301 sample questions on ExamPractice are a reasonable place to take that first sounding, with fuller timed simulations available to subscribers.
One retired-exam warning while you shop for materials: the old 200-125 CCNA and the track-specific CCNAs (Wireless, Security, Collaboration) belong to the pre-2020 programme. Study only 200-301 v1.1 content.
This question deserves a direct answer because job seekers agonise over it. For a network administration career, CCNA is the stronger signal; Network+ is the gentler on-ramp. In brief:
| Factor | CompTIA Network+ (N10-009) | Cisco CCNA (200-301 v1.1) |
|---|---|---|
| Difficulty | Moderate — concept recognition | Harder — configuration fluency |
| Prerequisites | None (A+ recommended) | None (≈1 year experience suggested) |
| Cost (US, 2026) | ~$399, varies by region | $300 + taxes, varies by region |
| Best for | First network role; vendor-neutral HR filters | Hands-on admin and engineer roles |
| Career path | Feeds any vendor track | Feeds CCNP → CCIE |
| Skills proved | How networks work | How to configure and troubleshoot them |
| Renewal | 3 years; 30 CEUs (CompTIA CE) | 3 years; 30 CE credits or exams (Cisco CE) |
Note the two CE programmes are unrelated — CompTIA CEUs do not renew Cisco certifications or vice versa. Doing both certifications in sequence is common and not wasteful: the overlap becomes revision, not redundancy. If you already hold Network+ and want the full decision logic for what follows it — including the security and cloud branches this article deliberately leaves alone — see what certification to take after CompTIA Network+.
Best for: administrators with three or more years in, targeting senior admin or network engineer titles.
CCNP Enterprise is where certifications start moving job grades rather than just passing filters. The structure is a core exam plus one concentration of your choice:
That is roughly $700 minimum in exam fees, with no formal prerequisite — Cisco suggests three to five years of experience, and the material enforces that suggestion ruthlessly. Validity is three years; renewal takes 80 CE credits, one professional core exam, two concentration exams, or combinations. A quirk worth exploiting: any Cisco exam you pass renews all your lower and equal active Cisco certifications, so a CCNP candidate never separately renews a CCNA. When you reach the ENCOR study phase, working through ENCOR 350-401 practice questions by domain will show you whether the automation sections — the newest material for most admins — are keeping pace with your routing knowledge; ENARSI 300-410 practice questions do the same for the concentration.
The Skillsoft survey figure quoted at the top — US CCNP Enterprise respondents averaging $144,912 — is the clearest data point in this pack for why Tier 3 is worth the grind, with the usual caveat that survey averages bundle experience with credentials.
Best for: admins in niche environments, multi-vendor shops, or aiming past "administrator" entirely.
In service-provider networks, research and education networks, and a meaningful slice of enterprises, Juniper hardware rules, and Cisco credentials only partially translate. Juniper's certification programme mirrors the associate-to-expert shape — JNCIA-Junos at associate level, with professional-tier credentials such as the JNCIP above it. This research pass did not verify Juniper's current exam fees or formats, so confirm details on juniper.net before planning; the practical guidance stands regardless: if your employer runs Junos, a JNCIA is worth more to your next appraisal than a second Cisco concentration. ExamPractice hosts materials for Juniper's professional routing-and-switching tier — see the JNCIP-ENT enterprise routing and switching page — though always match any study material's exam code against Juniper's live tracks first.
Many network administrator roles quietly include firewall administration, and shops standardised on Fortinet increasingly value Fortinet's own certification track when hiring for them. Specific exam names, tiers and prices were not verified for this guide — check fortinet.com — but the selection principle is the same as with Juniper: certify on the equipment your racks actually contain. Deep security-operations careers, as opposed to firewall administration within a network role, follow a different certification ladder that sits outside this article's scope.
Above and beside CCNP Enterprise sit Cisco's other tracks — Security, Data Center, Service Provider, and the Automation track (renamed from DevNet on 3 February 2026) — each following the same core-plus-concentration pattern with standard professional-level pricing widely reported at $400/$300. For a network administrator, the Automation track deserves particular attention: ENCOR v1.2's shift and CCNA v1.1's additions both signal that scripting and controller-based management are becoming assumed skills rather than differentiators. And at the summit, the CCIE Enterprise Infrastructure remains the field's most feared credential: the $400 ENCOR qualifier plus an eight-hour hands-on lab at US $1,600 per attempt, with a 30-day wait after a failed lab. It belongs on a five-year plan, not a one-year one.
For some administrators, the ladder's point is a better version of the current job: fewer escalations, better pay band, first pick of interesting projects — CCNA and one CCNP concentration deliver that. For others, it is a stepping-stone to a network engineer title, and that transition involves more than exams: portfolio labs, automation skills and interview positioning. That full role-change roadmap is covered in certifications that can help you become a network engineer, which picks up precisely where this ranking stops. Either way, the sequencing here holds: foundation before core, core before professional, and always the vendor whose logo is on your switches.
