Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 84

A heterogeneous network of vendors and device types needs automating for better efficiency and to enable future automated testing. The network consists of switches, routers, firewalls, and load balancers from different vendors; however, they all support the NETCONF/RESTCONF configuration standards and the
YANG models with every feature the business requires. The business is looking for a buy versus build solution because they cannot dedicate engineering resources, and they need configuration diff and rollback functionality from day 1.
Which configuration management or automation tooling is needed for this solution?

Answer options

Correct answer: C

Explanation

The correct answer is C, NSO, as it is specifically designed to manage heterogeneous networks and supports NETCONF/RESTCONF along with YANG models, making it ideal for this scenario. PyATS is more focused on testing rather than configuration management, AppDynamics is primarily an application performance monitoring tool, and Puppet is better suited for managing configurations in more homogeneous environments.
