300-435 Question 305
Single answerA network engineer is configuring a WebHook alert API to notify an external application whenever a critical event occurs in the network. The engineer wants to ensure that the external application receives real-time updates and can process them immediately. Which key component must be configured for the WebHook API to function correctly?
- A
The callback URL of the external application
- B
The polling interval for the WebHook API
- C
The authorization token for API authentication
- D
The IP address of the network device generating the alert
Show answer and explanation
Correct answer: A
Explanation
WebHooks rely on a push-based mechanism, where updates are sent to a specified endpoint (callback URL) in real-time. Configuring the correct callback URL ensures that the external application receives the notifications as intended. Other elements like authorization tokens are important for security but are secondary to the callback URL in terms of the WebHook's core functionality.
- A. Correct.
The callback URL is essential because it defines where the WebHook will send the alert notifications. Without it, the WebHook cannot deliver the updates to the external application.
- B. Incorrect.
Polling intervals are not relevant for WebHooks, as they operate on a push-based mechanism rather than polling.
- C. Incorrect.
While an authorization token is often required for security, it is not the primary component that determines where alerts are sent.
- D. Incorrect.
The IP address of the network device generating the alert is not a required configuration for the WebHook API to send notifications.
