A 2020 ranking of networking certifications can be useful for understanding the field, but a modern learner needs more than a dated list. Network work now overlaps with cloud infrastructure, identity, security and automation. Foundational skills remain valuable: addressing, routing, switching, troubleshooting and service reliability. Choose a credential for the responsibilities you want to develop, then use a small lab to demonstrate what you understand. The five directions below are alternatives for different goals, not a required sequence of exams.

CompTIA Network+ for broad fundamentals

Network+ can introduce a vendor-neutral vocabulary for connectivity, cabling, addressing, common protocols, wireless technologies and operational troubleshooting. It can be an appropriate first direction for support professionals who manage mixed environments. A practice lab might contain a router, two subnets, a DNS service and intentionally introduced faults. Document which tests you performed and why they narrowed the cause. Compare any training materials against CompTIA's active objectives before investing in a voucher.

Cisco CCNA for routing and switching practice

CCNA is useful for candidates planning to administer or troubleshoot enterprise networks. Cisco's 200-301 exam continues as a single associate certification, with a published blueprint that includes network fundamentals, network access, IP connectivity, IP services, security and automation. Cisco has announced that CCNA v1.1 testing continues through February 2, 2027, with v2.0 beginning February 3, 2027. That date matters for study scheduling. Verify the current version when booking and avoid assuming a 2020 course covers every present exam objective.

Security fundamentals for network professionals

A network technician benefits from understanding identity, least privilege, segmentation, logging and basic incident response. Security+ can provide a broad framework, but it is not the same credential as an advanced network-security specialization. Demonstrate security awareness by building a small segmented network, documenting authorized traffic and investigating a simulated access failure. Avoid exposing real public systems during experiments. The educational goal is to recognize how changes in network access affect applications and users, not to collect as many badges as possible.

Juniper JNCIA-Junos as a platform-specific alternative

Juniper's associate Junos program addresses the Junos operating system, routing concepts, configuration and operational tools. The issuer's JNCIA-Junos program lists exam JN0-106 and describes the tested objectives. This is worth exploring if your target employer operates Juniper equipment or if you want to compare network operating models. In a lab, use documented commands to inspect interfaces and routing information, then explain the differences between configuration and operational states. Confirm the active issuer blueprint before using an older course's exact commands.

Network automation as an adjacent path

A scripting-focused learner may prefer to complement networking knowledge with automation skills. Python, structured data, APIs and version-controlled configuration can reduce repetitive work when designed carefully. Cisco and other vendors have offered developer-oriented credentials, but individual program names and versions can change. Review the active catalog rather than treating a historical DevNet exam label as permanent. Automate a harmless inventory report in a test environment and validate the output manually before considering any configuration changes.

What employers look for beyond the exam

Employers usually want evidence that someone can diagnose connectivity issues without guesswork, communicate an outage clearly and make safe changes. Create a project that includes an IP plan, a topology diagram, configuration backups and a troubleshooting log. Explain why you chose a route, what a packet capture proved and how you restored service after a bad setting. These artifacts are valuable even if the candidate is studying independently and has not yet received an exam credential.

Building a realistic preparation timetable

Choose one target role and one relevant credential. Map current exam objectives to tasks, then reserve weekly time for labs and reviewing failed exercises. Keep a list of topics you cannot yet explain without notes. Use official training material where possible and treat community question banks critically; memorized answers cannot replace understanding. Before scheduling, check the active version, retake rules and exam delivery options on the issuer's website. Leave room to adjust if a version transition approaches while you are still studying.

Final perspective

The most useful part of a 2020 networking-certification list is the idea that structured learning can help beginners enter the discipline. The details must be refreshed. Current objectives, hands-on troubleshooting and clear evidence of ability make a stronger foundation than salary promises or a permanently ranked set of certification names.
