Is this for me?

People in this work enjoy
  • Working out why something is not connecting, like a puzzle
  • Hands-on work with real equipment, cables and command-line tools
  • Knowing that offices, banks and hospitals depend on your work
It may not suit you if you dislike
  • Faults can happen at night or on holidays, so on-call and shift work is common in support roles
  • You must keep learning, because tools and exam versions keep changing
  • Early jobs can be repetitive support work with modest pay
Class 11–12 subjects
For B.Tech: Class 12 with Physics and Maths, plus Chemistry, Computer Science or another allowed subject. Colleges usually ask for about 45% overall (40% for reserved categories); check each college's notice. Or a 3-year diploma in computer/IT/electronics after Class 10.
First degree
B.Tech/B.E. in Computer Science, IT or Electronics & Communication (4 years), or a 3-year diploma in IT/computer engineering. Some people then do a lateral-entry B.Tech.
Entrance exams
B.Tech entry: JEE Main, a state CET or the college's own test, depending on the college. Then the Cisco CCNA exam (200-301), a 120-minute test with no prerequisites.
Licence or registration
None needed to start working.
Subjects that keep this door openClass 11–12: Physics + Mathematics.Maths and Physics help; computers a plus.Way back: You can add the missing subject later as an extra subject (for example through NIOS) and still apply, but check the exam's and college's rules.

What the work is like

Planning office and campus networks; setting up routers, switches, Wi-Fi and firewalls; watching network health; finding and fixing faults; keeping networks secure; documenting changes.

A day in the work
You start by checking the dashboard for overnight alerts, such as a slow link at a branch office or a Wi-Fi access point that went offline. You fix what you can, and raise a ticket or call the service provider for the rest. Later you might configure a new switch, test a firewall rule, or join a call to plan a planned shutdown. Before you leave, you write down every change you made so the next person can follow it.

The path, step by step

  1. Step 1 · Class 10–11Choose PCM, ideally with Computer Science or Informatics Practices. Or take a 3-year diploma in computer or IT engineering after Class 10. Start learning how Wi-Fi, routers and the internet work.
  2. Step 2 · Class 12Apply to a B.Tech in CSE, IT or ECE through JEE Main, a state CET or the college's own test. Diploma students can later join B.Tech in the second year through lateral entry, which AICTE recognises. (reported — check with the official body)
  3. Step 3 · 3–4 yearsStudy computer networks, operating systems (especially Linux) and basic programming. Practise on free tools like Cisco Packet Tracer, and build small lab networks.
  4. Step 4 · Final year or just afterTake the Cisco CCNA exam (200-301). It covers network basics, switching, routing, IP services, security basics and automation. Cisco lists no prerequisites, and the certificate is valid for 3 years. Cisco's current exam version (v1.1) can be taken until 2 February 2027. A new version (v2.0) starts on 3 February 2027, so check the Cisco site before booking.
  5. Step 5 · First jobMost people start in network support or a network operations centre (NOC), watching alerts and fixing basic faults. The National Career Service describes this entry role as a desk job in IT-ITeS. (reported — check with the official body)
  6. Step 6 · After 2–5 yearsMove to design and bigger networks. Many specialise in firewalls and security, Wi-Fi, cloud networking or automation. Higher Cisco certificates such as CCNP are a common next step.

Ways in

  • B.Tech routeClass 12 (PCM) → B.Tech in CSE/IT/ECE (4 years) → CCNA → network or support engineer job. This is the most common route for design roles and larger companies.
  • Diploma routeClass 10 → 3-year diploma in computer/IT engineering → CCNA → junior network job. You can later join B.Tech in the second year through lateral entry if you want a degree.
  • Class 12 plus certified trainingThe National Career Service lists Class 12 plus certified training (aligned to the IT-ITeS Sector Skills Council's Associate Network Engineer standard) as the preferred entry for support-level network roles. Growth beyond that usually needs a degree and certificates.

Good to knowThe CCNA is a voluntary paid certificate, not a licence, and it is valid for 3 years; fees vary by college, so compare fee pages.

Fees from: Cisco: CCNA exam cost and validity · AICTE Approval Process Handbook 2024-27 · KGEC Admissions 2026–2027 (official college site) · Haridwar University BTech fees 2026 post (university website; cites its fee page) · Government College of Engineering, Amravati fee structure page (official; PDFs listed, figures not read). Fees change every year — check the college's own fee page before you pay.

What people earn

Pay starts modest in support and NOC roles and grows with experience, certificates and skills like security or cloud; it also depends on the city and on whether you work for an IT services firm, a product company, a bank or a telecom provider.

Myth and fact

Myth: Clearing CCNA alone will get you a good network engineer job.
Fact: CCNA shows you know the basics, but employers also look for a degree or diploma, hands-on practice and good troubleshooting. Most people start in support or NOC roles and grow from there.

Try it now

  • Class 7–9Draw a map of the Wi-Fi at home: the router, every device connected to it, and which ones use wires. Ask an adult to show you the router's settings page.
  • Class 10–12Take Cisco's free Networking Basics course and try the free Packet Tracer simulator to build a small network on screen.Open link ↗
  • College or afterFollow the free NPTEL/SWAYAM Computer Networks course from IIT Indore, and add a small lab project such as setting up two networks in a simulator and linking them.Open link ↗

Good to know

  • CCNA is a voluntary industry certificate from Cisco, not a government licence. No law requires it, but many employers look for it.
  • The CCNA exam is held at test centres or online and is priced in US dollars (listed at $300 by Cisco). The rupee cost depends on the exchange rate and taxes.
  • Check that your college or polytechnic is AICTE-approved before you take admission.
  • Networking overlaps with cybersecurity and cloud work. If you like this field, look at those careers too.
