Certified Wireless Network Administrator (CWNA)

The CWNA-109 content on WLAN design and regulatory compliance is well-covered here. I did wish there were more scenario-based site survey questions, but the RF theory sections more than made up for it. Passed first try, though it took real effort.

I underestimated how much CWNA-109 covers beyond basic Wi-Fi setup - roaming protocols and spectrum analysis go surprisingly deep. NerdExam helped me find my knowledge gaps before I sat the real thing. If you are serious about wireless networking, this is the right way to prep.

RF propagation finally makes sense. CWNA-109 passed.

Years of Wi-Fi work didn't prepare me for CWNA-109's depth on 802.11ax and MU-MIMO. The questions here push you to think through channel planning at a genuine design level.

Site survey concepts clicked after drilling these questions.

The 802.1X and EAP method coverage on CWNA-109 is no joke. Drilling enterprise authentication scenarios here made the security domain much less intimidating on exam day.
