Single answerA network administrator is configuring an external captive portal for a guest Wi-Fi network using Cisco DNA Center. The administrator wants to leverage the External Captive Portal API to redirect users to an external web page for authentication. Which of the following steps is essential for successful integration of the captive portal with the API?
- A
Ensure the external portal provides a valid URL for redirection after authentication.
- B
Enable HTTPS communication between the Cisco DNA Center and the external portal.
- C
Configure a firewall rule to block all traffic to the external captive portal.
- D
Use a pre-shared key for authentication between the Cisco DNA Center and the external portal.
Show answer and explanation
Correct answer: B
Explanation
When integrating an external captive portal with Cisco DNA Center using the External Captive Portal API, secure communication is paramount. HTTPS ensures data integrity and confidentiality during communication between the Cisco DNA Center and the external portal. While other steps like redirection are important, enabling HTTPS is essential for API-based integration.
- A. Incorrect.
This is necessary for user redirection, but it is not directly related to the use of the External Captive Portal API.
- B. Correct.
This is a critical requirement for secure communication and integration using the External Captive Portal API.
- C. Incorrect.
Blocking traffic to the external captive portal would prevent the solution from functioning correctly.
- D. Incorrect.
The External Captive Portal API does not rely on a pre-shared key. It typically uses HTTPS and token-based authentication.
