300-435 Question 225
Single answerYou are tasked with automating the deployment of device configurations across a Cisco SD-WAN network. Using the Template APIs, you apply a pre-configured feature template to a group of devices in your network. After applying the template, you notice some devices fail to synchronize the configuration. What is the most likely step you should take using the Template APIs to troubleshoot this issue?
- A
Retrieve the device configuration status using the Template Status API.
- B
Reapply the same feature template without any modifications.
- C
Delete the devices from the network and re-add them before reapplying the template.
- D
Fetch the device-specific errors using the Template Attach API and resolve any mismatched variables.
Show answer and explanation
Correct answer: D
Explanation
When applying templates via Template APIs, failures can occur due to mismatched variables or device-specific errors. The Template Attach API provides detailed error messages and validation outputs that can help identify and resolve issues. Simply reapplying the template or performing drastic actions like deleting devices without understanding the cause of the failure would be inefficient and potentially disruptive.
- A. Incorrect.
This option is incorrect because while retrieving the configuration status using the Template Status API can provide a high-level status, it does not provide the specific variable mismatches or errors needed to troubleshoot failed synchronizations.
- B. Incorrect.
This option is incorrect because reapplying the same template without addressing the root cause of the failure will likely result in the same issue.
- C. Incorrect.
This option is incorrect because deleting and re-adding devices is a drastic measure and is not necessary for troubleshooting template application errors.
- D. Correct.
This option is correct because the Template Attach API allows you to fetch specific errors, including variable mismatches or validation issues, which can help you identify and resolve the problem.
