Cisco 350-401: Cisco pyATS for Network Validation
Network automation is incomplete if it can make a change but cannot prove the network still behaves correctly afterward. Cisco pyATS addresses that validation problem with a Python-based test framework and the Genie libraries for device connectivity, parsers, APIs, and network-oriented models.
‘ A test can confirm that neighbors remain up, interfaces keep the right state, routes exist in the correct VRFs, or key counters do not regress. That makes 350-401 ENCOR automation topics concrete: validation becomes part of the change process rather than an afterthought.
