5 Best Certifications for Network Engineers in 2026 (And the Order to Take Them)

The right first certification for anyone without an IT job, and largely redundant for anyone who already has one.

It covers networking fundamentals without any vendor’s syntax: the OSI model, addressing and subnetting, routing and switching concepts, wireless, cloud networking basics, security fundamentals and a structured troubleshooting method.

Being vendor neutral is the point. You learn how networks work rather than how one manufacturer’s command line works, and that transfers to Cisco, Juniper, Aruba, Fortinet or any cloud platform.

The DoD 8140 approval is the practical advantage. Roles with the US government or its contractors frequently require an approved certification, and Network+ is one. If that sector interests you, this is a hard requirement rather than a preference.

It is also easier than CCNA. That matters more than pride: passing something builds momentum, and failing an expensive exam early puts people off entirely.

The Sybex study guide covers the N10-009 objectives with practice questions, and is the standard preparation text alongside video courses.

Be honest about its limits. It teaches concepts, not configuration. You will finish able to explain how OSPF works and unable to configure it on anything. That is why CCNA follows it rather than replacing it.

Renewal is through CompTIA’s continuing education programme with an annual fee, or automatically by passing a higher CompTIA certification.

The single most useful certification in networking, and the one most job adverts for network roles actually name.

It covers network fundamentals, access, IP connectivity, IP services, security fundamentals, and automation and programmability, and it expects configuration rather than description. You will be asked what a command does and what to type to achieve something.

That practical bias is why it carries weight. A hiring manager reading CCNA on a CV assumes you have logged into a switch and made it do something, which they cannot assume from a purely conceptual certification.

The automation and programmability section is the modern addition worth noting. Cisco added it because the industry moved, and it signals where the field is going even at associate level.

How to prepare. The Official Cert Guide library is two volumes and is the standard text. Reading it is not enough. You need hands on practice, and there are three ways: Cisco Packet Tracer, which is free and adequate for CCNA; GNS3 or EVE-NG with real IOS images, which is closer to reality; or second hand physical switches, which teach cabling and console access properly.

Budget three to six months of consistent study. People who pass in six weeks usually had relevant experience already.

The Sybex kit at $35.26 is a cheaper alternative with practice tests, and many people use both.

Renewal is by continuing education credits or by passing another Cisco exam, and passing CCNP renews it automatically.

This is where the salary difference is, and it is the certification most network engineers put off for too long.

It covers VPC design, hybrid connectivity through Direct Connect and VPN, Transit Gateway architectures, DNS at scale with Route 53, load balancing, and network security and monitoring in the cloud.

The scarcity is the point. Plenty of people understand traditional networking. Plenty understand cloud. Few understand the boundary between them, and that boundary is where hybrid networks break.

When on premises routing does not reach a cloud subnet, or DNS resolves differently on each side, or a Direct Connect fails over badly, the person who can diagnose it across both worlds is rare and valued accordingly.

Do not take this early. It assumes solid networking fundamentals and real AWS experience. Attempting it without both means memorising service names rather than understanding architecture, which the exam is designed to catch.

Two to three years into a network role, with CCNA behind you and some real exposure to cloud infrastructure, is the right moment.

The Sybex ANS-C01 guide is the current standard text. The older official study guide at $8.85 covers an earlier exam version, so it is useful background reading but should not be your primary preparation.

Azure has an equivalent path, and if your employer runs Azure, take that instead. The skill transfers; the exam does not.

The step from doing the work to designing it. Take it when you want senior, lead or design responsibility.

The structure is two exams: the ENCOR core exam covering enterprise infrastructure, virtualisation, security, automation and assurance, plus one concentration exam in an area you choose such as advanced routing, SD-WAN, wireless or automation.

That structure is genuinely good, because it lets you specialise while proving broad competence. Choose the concentration that matches where you want to work rather than the one that looks easiest.

The core exam is shared with CCIE Enterprise, so passing ENCOR is also the written requirement toward CCIE if you go that far.

Passing CCNP renews CCNA automatically, which is worth factoring into the cost. Two exams at roughly $400 each is not cheap, and removing a separate CCNA renewal takes some of the sting out.

Study time is significant. Six to twelve months for most people working full time, and the ENCOR exam has a reputation for breadth: it asks about many topics at moderate depth rather than a few in detail.

The Official Cert Guide is the standard text. The Fast Track guide at $29.99 is a useful supplement with decision tables and troubleshooting cues, but it is not sufficient on its own for an exam this broad.

Consider whether you want this. It deepens Cisco expertise, which pays well and is narrower than adding cloud skills. If you want to be a Cisco specialist, take it. If you want to be broadly employable, take the cloud path first.

The cheapest way into a vendor certification, and genuinely valuable in one specific part of the industry.

Juniper equipment is heavily used by internet service providers, telecommunications carriers and large data centres. In those environments, Junos knowledge is worth more than Cisco IOS knowledge, and far fewer engineers have it.

JNCIA-Junos covers networking fundamentals, the Junos operating system, user interfaces, configuration basics, operational monitoring and routing fundamentals.

Junos is a genuinely different operating system, not a variation on IOS. It uses a hierarchical configuration with commit and rollback, which means you stage changes and apply them atomically, and you can roll back to a previous configuration with one command. Anyone who has broken a network with a half applied change will appreciate why that matters.

Learning it also makes you a better engineer generally, because seeing a second approach separates the concepts from one vendor’s implementation of them.

Juniper periodically runs free or heavily discounted voucher promotions through its learning portal, so check before paying full price.

The limitation is demand. Outside service providers and large data centres, most enterprise job adverts name Cisco. If you are aiming at ordinary corporate network roles, CCNA is the better first vendor certification and this is a strong second.

Preparation material is thinner than Cisco’s, though Juniper’s own documentation is excellent and free, and vSRX and vMX images allow lab practice.
