300-435 Question 110
Single answerA network engineer is tasked with automating the collection of network device metrics using Cisco DNA Center. The metrics should be gathered at regular intervals to ensure up-to-date performance data is available for analysis. Which approach should the engineer use to configure automation with a periodic cadence?
- A
Configure a Python script to execute on-demand via an API call to Cisco DNA Center.
- B
Set up a Cisco DNA Center Assurance automation task with a recurring schedule.
- C
Use a REST API to retrieve metrics once and export them to an external monitoring tool.
- D
Configure an event-based webhook in Cisco DNA Center to collect metrics when specific conditions are met.
Show answer and explanation
Correct answer: B
Explanation
To achieve periodic data collection, a recurring schedule or task is required. Cisco DNA Center provides the ability to configure Assurance-based recurring automation tasks, ensuring metrics are collected at regular intervals without manual intervention. This aligns with the principle of periodic cadence in automation.
- A. Incorrect.
On-demand API calls are not suitable for periodic data collection, as they require manual or additional external automation triggers.
- B. Correct.
Setting up a recurring task in Cisco DNA Center aligns with the requirement for periodic cadence, as it ensures metrics are collected at regular intervals automatically.
- C. Incorrect.
Retrieving metrics a single time does not fulfill the requirement for regular data collection over time.
- D. Incorrect.
Event-based webhooks depend on specific triggers or conditions, which do not guarantee periodic data collection at regular intervals.
