Goal: enforce captive portal authentication overHTTPSfor guests.

On FortiGate/FortiAuthenticator captive portal setups:

HTTP redirectis used so that when a guest browses to any HTTP site, their request is redirected to theportal URL.

Theportal URLitself must beHTTPSif you want a secure login page.

FortiOS captive portal and firewall authentication guidelines recommend:

EnablingHTTP redirectso unauthenticated HTTP traffic is transparently sent to the portal.

Configuring theportal URL with HTTPS, often referencing a certificate on FortiGate or FortiAuthenticator.

Therefore:

A. Enable HTTP redirect in the user authentication settings.✔This ensures unauthenticated HTTP requests are redirected to the (now HTTPS) portal.

D. Update the captive portal URL to use HTTPS on FortiGate and FortiAuthenticator.✔This makes the login itself secure (TLS-protected).

Incorrect:

B– You don’t need a new SSID; the same SSID can use HTTPS portal.

C– Disabling HTTP admin access on the SSID doesn’t control the captive portal scheme; HTTPS enforcement is done by the portal configuration and redirect, not by admin-access flags.

Auto TX power control on FortiAP is an RF-optimization feature:

FortiGate (as wireless controller) continuously evaluatesRSSI of associated clientson each FortiAP radio.

The algorithm focuses on theweakest client(the one with the worst signal) and adjusts the AP’s transmit power so that this client’s signal level stays within a configured / target range.

This helps balance coverage and limit co-channel interference: APs don’t transmit at maximum power when clients are close, but will increase power when the weakest client signal drops too low.

Therefore the correct behavior description is:

✔C– AP power is adjusted based on the weakest associated client’s signal.

Why the others are wrong:

AandBtalk about matching nearby APs’ power or forcing everything to –70 dBm, which is not how FortiAP auto TX works.

Dincorrectly states the AP “evaluates its own transmission from the client perspective”; the AP can only infer client-side conditions from theclient’s RSSI at the AP, not the inverse.

In user certificates used with FortiGate / FortiAuthenticator / SSL-VPN / 802.1X, the following attributes are important:

Subject field & UPN

Provide a unique identity for the user (CN and/or UPN).

FortiGate can use theSAN/UPNfield for LDAP-integrated certificate authentication.

Expiration date

Limits how long the certificate is valid, enforcing lifecycle and rotation.

CRL URL & OCSP URL

Tell FortiGate (or any relying party)where to check if the certificate has been revoked.

Enablesnear real-time revocationusing OCSP or periodic CRL downloads instead of relying only on expiration.

By carefully configuring these fields:

The certificate uniquely and correctly identifies the user.

Relying systems can performaccurate and timely revocation checks, improving security.

Why other options are wrong:

A: It does the opposite—CRL/OCSP increase automation, not manual revocation.

B: These attributes do not inherently limit a cert to specific devices; that’s done via key usage, EKU, or device certs.

D: They don’t “ensure universal validity”; they make the certprecisely boundto one identity with enforceable lifetime and revocation.
