Networking careers and certifications: jobs, skills, certificates, home labs and a study plan
Every organisation that uses computers needs networks, and someone to design, install, secure and fix them. Kenya's growth in fibre, mobile data, data centres, fintech and cloud services keeps demand steady for people with networking skills, from technicians who install fibre and CCTV to engineers who run ISP backbones and cloud networks. This unit maps the career paths, the skills and certifications employers look for, how to get hands-on practice cheaply, and a realistic study plan.

Who hires
In Kenya: ISPs and telcos (Safaricom, Airtel, Liquid, Jamii Telecom/Faiba, Zuku and many regional ISPs), banks and SACCOs, system integrators and IT companies, data centres, universities and schools, hospitals, county and national government, NGOs, hotels, manufacturers, and many SMEs that need someone who can "do networks". Abroad and remotely: managed service providers, cloud companies and NOCs serving many time zones (the remote jobs lesson in Make Money Online explains how to find these).
Freelance and small business opportunities: installing networks and CCTV for offices, schools and estates; Wi-Fi hotspot businesses; maintenance contracts.
Skills employers want
Technical:
- IP addressing, subnetting (fast and accurate), VLSM
- Switching, VLANs, STP; routing (static, OSPF), NAT
- Wi-Fi planning and troubleshooting
- Firewalls and VPNs; security basics
- Linux and Windows basics; DNS and DHCP
- Structured cabling and fibre basics; using testers
- Monitoring tools; basic Python/automation
- Vendor platforms common in Kenya: Cisco, MikroTik, Ubiquiti, Huawei, Fortinet
Soft skills: clear communication with non-technical users, documentation, calm troubleshooting under pressure, customer service, reliability, willingness to learn constantly.
Certifications (in a sensible order)
| Stage | Certificate | Why |
|---|---|---|
| Start (optional) | CompTIA A+ or equivalent IT basics | Hardware, OS and support fundamentals |
| Core | CompTIA Network+ or Cisco CCNA | The core networking certificates; CCNA is the most recognised and covers everything in this subject and more |
| Local value | MikroTik MTCNA | Very useful in Kenya where many ISPs and offices use MikroTik routers |
| Wireless | Ubiquiti or vendor wireless courses; CWNA for specialists | Wi-Fi design |
| Security | CompTIA Security+, Cisco CyberOps Associate, Fortinet NSE courses | Security roles |
| Cloud | AWS Cloud Practitioner → Solutions Architect Associate; Azure Fundamentals → Network Engineer | Cloud networking |
| Advanced | Cisco CCNP, MikroTik MTCRE, vendor professional levels | Senior engineering |
| Automation | Cisco DevNet Associate / CCNA automation topics | Network automation |
Tips: certifications open doors, but employers also want hands-on proof. Check current exam prices and objectives on each vendor's website; prices are in US dollars and change. Cisco Networking Academy courses are offered through many Kenyan universities and colleges.
Build a home lab
| Option | Cost | Use |
|---|---|---|
| Cisco Packet Tracer | Free (NetAcad account) | Simulate routers, switches, PCs: perfect for CCNA labs |
| GNS3 / EVE-NG | Free community versions | Run real router images (advanced, needs a good PC) |
| MikroTik CHR (Cloud Hosted Router) | Free limited licence | Practise RouterOS in a virtual machine |
| Second-hand gear | Low cost | Old Cisco switches/routers, a MikroTik hAP, a managed switch |
| Raspberry Pi / old PC | Low cost | Linux server: DNS (Pi-hole), DHCP, monitoring |
| Cloud free tiers | Free/low cost | Build VPCs and VPNs in AWS/Azure/Google Cloud (watch billing alerts) |
A portfolio that proves your skills
- Lab write-ups on GitHub or a blog: "VLANs and inter-VLAN routing for a school", with diagrams (draw.io), configs and screenshots.
- A Packet Tracer file of a full small-business network.
- A real project: networking a church, small office or relative's shop (with permission and photos of neat cabling).
- Scripts from the Python networking lesson (IP plan generator, CSV validator).
- A clean LinkedIn listing skills, certs and projects.
A 12-week study plan (1–2 hours a day)
| Weeks | Focus | Practice |
|---|---|---|
| 1–2 | Networking basics, OSI/TCP-IP, cables, binary | This subject's first lessons; binary game |
| 3–5 | IPv4, subnetting, VLSM, summarisation | 20 subnetting questions daily with the practice tool |
| 6–7 | Switching, VLANs, STP, ARP | Packet Tracer: build a 3-VLAN office |
| 8–9 | Routing, NAT, DHCP, DNS | Packet Tracer: two routers, OSPF, NAT to "internet" |
| 10 | Wi-Fi and security | Configure WPA2/WPA3, guest VLAN, ACLs |
| 11 | IPv6, troubleshooting, Python basics | Troubleshooting scenarios; scripts |
| 12 | Review and practice exams | Timed practice tests, then book the exam |

Getting your first job
- Get any IT foot in the door: helpdesk, attachment/internship, technician with an ISP or integrator.
- Volunteer: set up networks for schools, churches or community centres.
- Network with people: tech meetups, LinkedIn, Ajira Digital clubs, alumni groups.
- Tailor your CV to each job with specific skills ("Configured VLANs and inter-VLAN routing on Cisco switches") and link your portfolio.
- In interviews, expect subnetting on a whiteboard, OSI questions, and "how would you troubleshoot..." scenarios: practise talking through your method out loud.
- Keep learning: the field changes (Wi-Fi 7, IPv6, SD-WAN, cloud, automation).

Start with this subject and Packet Tracer; get an entry job or attachment (helpdesk, ISP installation technician) while studying for CCNA (and MTCNA for local value). Build a home lab and a portfolio of documented labs and real small projects. After CCNA and 1–2 years of hands-on work, move into network administration/engineering roles, then specialise (security, cloud, wireless or automation).
Summary
- Roles range from helpdesk and field technician to network, NOC, wireless, security, cloud and automation engineers.
- Employers include ISPs, banks, integrators, data centres, education, health and government, plus remote and freelance work.
- Core certs: Network+ or CCNA, plus MikroTik MTCNA in Kenya; then security, cloud or CCNP.
- Practise with Packet Tracer, GNS3/EVE-NG, MikroTik CHR and cheap hardware; document labs in a portfolio.
- Follow a structured plan, get any IT foot in the door, and keep learning.
