Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 492

An engineer is responsible for several thousand network devices across many campus environments that are all connected to a common controller. Which action updates all devices with new security settings in this network?

Answer options

• A. Get a list of all devices from the controller and use a CLI to change the settings on individual devices.
• B. Track a list of all devices on a spreadsheet and use a CLI to change the settings on individual devices.
• C. Get a list of all devices from the controller and use RESTCONF to set a YANG model on the devices.
• D. Track a list of all devices on a spreadsheet and use RESTCONF to set a YANG model on the devices.

Correct answer: C

Explanation

The correct answer is C because RESTCONF is designed to work with YANG models, allowing for efficient bulk updates across multiple devices through the controller. Options A and B require manual changes via CLI, which is not practical for thousands of devices. Option D also uses a spreadsheet, which is inefficient for managing large networks.
