300-435 Question 112
Single answerYou are tasked with automating configuration backups for network devices using Cisco DNA Center APIs. The requirement is to ensure backups are taken every day at a specific time. Which approach would best meet this requirement?
- A
Use a periodic scheduler within Cisco DNA Center to trigger the backup API daily.
- B
Manually trigger the backup API call from Cisco DNA Center's GUI each day.
- C
Configure a cron job on an external server to call the Cisco DNA Center backup API daily.
- D
Rely on Cisco DNA Center's default configuration backup behavior, as it automatically runs backups daily.
Show answer and explanation
Correct answer: C
Explanation
The requirement is to automate daily backups using Cisco DNA Center's API, which does not have a built-in periodic scheduler for API calls. An external mechanism, such as a cron job, is needed to ensure the backup API is triggered daily at the required cadence. This meets the automation and periodic requirements effectively.
- A. Incorrect.
Cisco DNA Center does not have a built-in periodic scheduler for triggering API calls directly. Additional external tools or configurations are required for scheduling API calls.
- B. Incorrect.
Manually triggering backups does not meet the requirement for automation and daily execution. This approach is not scalable or efficient.
- C. Correct.
Using a cron job on an external server to call the Cisco DNA Center backup API daily is a valid and effective automation solution. This approach ensures backups are scheduled and executed at the desired cadence.
- D. Incorrect.
Cisco DNA Center does not automatically perform daily backups unless explicitly configured. The task requires an automated solution to ensure periodic backups happen daily.
