QuestionQ277

Automation Design

An engineer is developing a framework for automated, repetitive tasks required to manage a Cisco Nexus 9000 Series Switch. The engineer intends to use a programmatic interface and must consider the following:

  • The customer environment requires the script to authenticate before performing further actions.
  • The customer’s security requirements require HTTP transport.
  • The automation team is familiar with parsing messages encoded in XML or JSON.

Which solution fulfills these requirements?

  • A SNMPv3
  • B gRPC
  • C RESTCONF
  • D NX-API
Explanation

NX-API exposes Cisco Nexus 9000 NX-OS CLI operations through HTTP/HTTPS, uses HTTP Basic Authentication, and supports XML and JSON message formats. It therefore supports authenticated, script-driven switch management using the required transport and encodings.
