Is the CCNA Still Worth It in the Age of AI?

Every few months, someone claims AI will replace all entry-level IT jobs. That includes helpdesk, NOC, sysadmin, networking, everything. They ask if the CCNA is worth it anymore. If you’re studying for the CCNA, it can feel discouraging. A manager or coworker might say, “Why bother? AI will make it useless.”

Here’s the truth. Networking isn’t going anywhere, and the CCNA is still extremely valuable. It remains one of the most important foundation certs in IT.

If someone is questioning whether the CCNA is still useful, here are the key points to keep in mind.

1. AI Doesn’t Replace Networks — It Runs On Networks

AI doesn’t magically remove routers, switches, firewalls, Wi-Fi, VLANs, or WAN circuits.

In fact, AI increases networking demands:

• More data centers
• More bandwidth
• More cloud connectivity
• More secure segmentation
• More observability and monitoring
• More complex traffic patterns

Every AI system still depends on someone configuring the network underneath it.
That “someone” is a network engineer.

2. Is the CCNA Still the Best Foundation for Real IT Skills — Is the CCNA Worth It?

Even if AI automates certain tasks, these fundamentals remain critical:

• Subnetting
• Routing
• Switching
• VLANs
• NAT
• IPv6
• Troubleshooting

AI can help explain concepts, generate configs, and assist with documentation. It can’t replace your ability to reason through a network outage. It also can’t trace packets or understand how traffic flows the way you can.

The CCNA builds thinking skills, not just memorization.

3. Networking Jobs Are Changing — But Not Disappearing

Here's what’s actually happening:

• Networking is becoming more automated, not eliminated.
• Engineers now use tools like Ansible, Terraform, and automation pipelines.
• Cloud networking is a huge new area (AWS, Azure, GCP).
• SD-WAN, Zero Trust, and microsegmentation are growing fast.

The CCNA gives you the foundation for all of this.

AI may help you write a config — but you still need to know what that config should do.

4. Employers Still Value the CCNA

Look at any job board and you’ll see:

• “CCNA preferred”
• “CCNA or equivalent knowledge”
• “Cisco networking experience required”

Companies still rely heavily on Cisco infrastructure.
They’re not replacing millions of switches overnight.

AI isn’t making these jobs vanish — it’s making them evolve.

5. Planning for “AI to replace everything in 2 years” is unrealistic

Most predictions are exaggerated.

AI is growing fast, but:

• Networks still need humans
• Infrastructure still breaks
• Companies still need troubleshooting
• Security still requires reasoning
• Cloud still needs architecture

No AI tool can walk into a server room or rewire a rack. It can’t configure VLANs end-to-end or redesign a company’s network topology.

That’s still your job.

6. The CCNA Gives You Options — Not Limitations

Studying for the CCNA doesn’t lock you into traditional networking.
It opens doors to:

• Cloud engineering
• Network automation
• Cybersecurity
• DevOps
• Infrastructure engineering
• Data center operations

All of these require strong networking fundamentals.

The CCNA is your foundation — not your endpoint.

Final Thoughts

The CCNA is far from useless — it’s still one of the most valuable certifications for building real technical skills. AI will change IT, but it won’t erase the need for people who understand how networks work.

If you enjoy networking or want to move into cloud or security, the CCNA is absolutely worth it.

Keep studying, stay consistent, and ignore the noise.
