A civic Wi-Fi captive portal asks users for an email address before granting Internet. What function does that portal primarily provide?
Select an answer to reveal the explanation.
Short Explanation
You associate first; then the portal is the velvet rope—email, accept terms, then the Internet opens. It is a web gate after join, not a replacement for association, a DNS black hole by design, or proof of WPA3 everywhere.
Full Explanation
Captive portals typically allow association (often on open or guest SSIDs) and then intercept browsing to present a login/accept page before full network use. They do not replace 802.11 association, permanently disable DNS as their purpose, or certify WPA3-SAE across a mesh.
