Which certification should you actually take first?

Every mentee asks this in about week two, usually after watching a video that promised a six-figure salary from one exam. Here's what I actually tell them.

Certifications do two things. They teach you a body of knowledge in a structured order, and they get your CV past a filter. Those are different jobs, and which certification is right depends on which job you need done. They do not, on their own, get anyone hired.

If you have no experience at all: CompTIA A+

A+ covers hardware, operating systems, mobile devices, troubleshooting, and the basics of networking and security. It is broad and shallow, which is exactly right when you don't yet know what you like. It's also the certification most commonly named in entry-level help desk postings, so it clears filters.

The catch: it's two exams, and the material includes a fair amount of memorisation about connector types you'll rarely meet. Budget three to four months at an hour a day.

If you already know you like networks: Cisco CCNA

CCNA is a serious exam and a serious signal. It goes deep on routing, switching, IP addressing, and increasingly on automation. People who pass it can usually explain what happens between typing a URL and seeing a page, which is more than a lot of working engineers can do.

Don't start here cold. Do Network+ or the free Cisco introductory courses first, and give yourself six months.

If you want cloud: AWS Cloud Practitioner or Azure AZ-900

Both are foundational, both are cheap, and both can be passed in four to six weeks of evenings. They are the fastest way to have something credible on a CV. They are also the ones most likely to be dismissed by a hiring manager if there's nothing else next to them, because they're knowledge exams rather than skills exams.

Pair either one with a small project you actually deployed. That combination is strong.

If you want security: not yet

Security+ is a good certification and I recommend it — second or third, not first. Security is a discipline layered on top of systems and networks. Studying it before you can confidently explain a subnet produces someone who can recite the CIA triad and cannot troubleshoot a firewall rule. Employers can tell.

The part nobody puts in the video

• Exams cost real money. Ask about vouchers before you pay full price. Schools, libraries, workforce programmes, and organisations like ours often have them. We can usually help.
• A certification with no projects behind it reads as hollow. Two of the best junior candidates I've interviewed had zero certifications and a home lab they could talk about for forty minutes.
• Study by doing. If your study method is watching, you will pass and then forget. Build the thing in a VM.

The certification opens the door. The lab is what you talk about once you're through it.

So, one answer

If you're 16 with no experience and you want the single highest-value first step: A+, studied in a home lab, finished in four months. If you're 22 and already working a support job: skip A+ and go straight at CCNA or a cloud associate exam, because you have the experience that makes the deeper certification pay off.
