300-435 Question 179
Select 4An administrator is configuring Cisco DNA Center to send event notifications to an external application using outbound webhooks. What steps must the administrator take to ensure the notifications are successfully delivered to the external application?
- A
Register the external application in Cisco DNA Center by providing the application URL and authentication details.
- B
Enable the required event subscription in Cisco DNA Center and specify the webhook as the delivery mechanism.
- C
Configure the external application to send a confirmation response (HTTP 2xx) after receiving the webhook payload.
- D
Ensure that the external application is hosted on-premises to avoid latency issues.
- E
Verify that the external application can parse JSON payloads, as event notifications are sent in JSON format.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To implement Cisco DNA Center event outbound webhooks, the administrator must configure both Cisco DNA Center and the external application properly. This includes registering the external application, enabling event subscriptions, and ensuring the external application can handle webhook payloads correctly (e.g., sending HTTP 2xx responses and parsing JSON). Hosting the external application on-premises is not a requirement, as webhooks can work with both on-premises and cloud-hosted systems.
- A. Correct.
This is correct. Cisco DNA Center requires the external application to be registered with the appropriate URL and authorization details to establish a secure webhook connection.
- B. Correct.
This is correct. Event subscriptions must be enabled, and the webhook delivery mechanism must be selected for the notifications to be sent.
- C. Correct.
This is correct. The external application must send an HTTP 2xx response to confirm successful receipt of the webhook payload; otherwise, Cisco DNA Center may retry or report an error.
- D. Incorrect.
This is incorrect. The external application does not necessarily need to be on-premises. Webhooks can work seamlessly with cloud-hosted applications as long as they are reachable and meet the required specifications.
- E. Correct.
This is correct. Cisco DNA Center sends event notifications in JSON format, so the external application must be able to parse JSON payloads to process the information.
