Question
Users must accept the terms presented in a captive petal when connecting to a guest network. Recently, users have reported that they are unable to access the Internet after joining the network. A network engineer observes the following:
- Users should be redirected to the captive portal.
- The Motive portal runs Tl. S 1 2
- Newer browser versions encounter security errors that cannot be
bypassed
- Certain websites cause unexpected re directs
Which of the following mow likely explains this behavior?
Options
- AThe TLS ciphers supported by the captive portal ate deprecated
- BEmployment of the HSTS setting is proliferating rapidly.
- CAllowed traffic rules are causing the NIPS to drop legitimate traffic

Explanation
The most likely explanation for the issues encountered with the captive portal is that the TLS ciphers supported by the captive portal are deprecated. TLS Cipher Suites: Modern browsers are continuously updated to support the latest security standards and often drop support for deprecated and insecure cipher suites. If the captive portal uses outdated TLS ciphers, newer browsers may refuse to connect, causing security errors. HSTS and Browser Security: Browsers with HTTP Strict Transport Security (HSTS) enabled will not allow connections to sites with weak security configurations. Deprecated TLS ciphers would cause these browsers to block the connection.
