Question
Options
- Aon the gateway at $NACPORTAL_ HOME/conf/httpd_ nac.conf
- Bon the management at SCPNAC_ HOME/conf/httpd_ nac.conf
- Con the management at SNACPORTAL_ HOME/conf/httpd_ nac.conf
- Don the gateway at $CPNAC_ HOME/conf/httpd_ nac.conf
Explanation
Option A is correct because the Captive Portal service runs on the gateway - this is where guest traffic is intercepted and redirected, so the configuration file naturally lives there under the $NACPORTAL_HOME environment variable, which points to the NAC Portal's installation directory.
Options B and C are wrong because they place the config on the management server, which handles policy and administration but does not host the Captive Portal service itself - the portal must reside on the gateway to intercept client HTTP requests in real time.
Option D is wrong because it uses the incorrect environment variable $CPNAC_HOME instead of the correct $NACPORTAL_HOME; while it correctly identifies the gateway as the host, the wrong variable path would not resolve to the actual config file.
Memory tip: Think "Portal lives at the gate" - Captive Portals run on the gateway (not management), and the variable starts with NAC*PORTAL* because it is the NAC Portal home, not a generic CP/NAC home.
