CompTIA Network+ in Johannesburg
Foundational networking certification covering infrastructure, operations, security, and troubleshooting.
What is CompTIA Network+?
CompTIA Network+ (exam code N10-009) is a vendor-neutral certification that validates your ability to design, configure, manage, and troubleshoot wired and wireless networks. It covers everything from network architecture and security to cloud connectivity and network operations. In Johannesburg, where demand for skilled network technicians is rising sharply across finance, mining, telecoms, and public sector IT, Network+ gives employers a reliable benchmark that you can hit the ground running. The certification is globally recognised, which matters in a city that hosts the African headquarters of numerous multinational corporations. Whether you're moving out of a helpdesk role or formalising skills you've already built on the job, Network+ is the logical first rung.
At an exam cost of $358 USD, CompTIA Network+ is a meaningful but manageable investment for Johannesburg-based professionals. With the average IT salary in the city sitting around $32,000 per year, a documented $6,000 annual salary uplift represents roughly an 18% pay increase — and most candidates recoup the exam fee within the first two months of a new role. Johannesburg's IT job market is competitive, and hiring managers increasingly filter CVs by recognised certifications. Network+ also renews every three years, keeping your skills current without constant re-examination. Factor in that the cert satisfies prerequisites for higher-level qualifications like Security+ and CCNA, and the long-term ROI compounds well beyond that initial salary jump.

Exam tips
Know your ports cold: the N10-009 exam regularly tests whether you can identify protocols by port number under time pressure — memorise at minimum the top 20 common ports (FTP, SSH, DNS, HTTP, HTTPS, RDP, SNMP, etc.)
For performance-based questions, read the scenario twice before touching any drag-and-drop or simulation element — misreading the topology or requirements is the most common cause of losing easy marks
Subnetting questions will appear and they are time-sensitive; practise until you can subnet a /24 into any required block size in under 90 seconds without a calculator
CompTIA's troubleshooting methodology (identify, establish theory, test, establish plan, implement, verify, document) is explicitly tested — learn the steps in order and apply them to every scenario question as a filter
The N10-009 version places greater emphasis on cloud networking and network virtualisation than previous versions; make sure you understand concepts like SDN, NFV, VPC, and how on-premises networks connect to cloud environments
