REST, or Representational State Transfer, is an architectural style that is characterized by its stateless nature, meaning each request from a client to a server must contain all the information needed to understand and complete the request without relying on any stored context on the server. This increases reliability and scalability. However, ‘stateful’ is not a guiding principle of REST; instead, it is ‘statelessness’ that is a core principle. The other main guiding principles include a uniform interface, cacheability, and a layered system

To create an SVI using NX-API CLI JSON-RPC interface, one would typically need to construct a Python dictionary that represents the RPC payload containing the necessary commands. The request call would then be made using a library like requests where this dictionary is passed as JSON data. In general terms, without specifying exact options since they are not visible in any provided resources or within my capabilities:

One option would likely involve specifying parameters for creating an SVI including its ID number.

Another option might involve setting specific attributes for the SVI such as name, description, or IP address. References :=

Cisco NX-OS iPXE supports both IPv4 and IPv6 network protocols. iPXE is an open-source network boot firmware that enhances the capabilities of the standard PXE by supporting additional protocols like HTTP and TFTP, which can operate over both IPv4 and IPv6 networks3.

Synchronous API calls are blocking, meaning they hold up code execution until a response is returned from the server. This can lead to perceived latency or performance lag in an application if not managed properly. In contrast, asynchronous API calls do not block code execution; they allow the program to continue running and handle the response once it’s available, typically through a callback function

In the NXAPI-CLI JSON-RPC interface on Cisco Nexus switches, the ‘cli’ command is used to execute non-configuration CLI commands, which is equivalent to a POST operation in this context. Therefore, option A is correct. References:

 The ucs_vlans module is part of the Ansible collection for Cisco UCS (Unified Computing System) and is used to manage VLANs on Cisco UCS Manager. When working with Cisco UCS, VLANs are a crucial aspect of network segmentation and management. The ucs_vlans module allows users to configure VLAN settings such as the VLAN ID, name, and state. It also supports advanced features like fabric configuration and multicast policies.

 To retrieve server profiles with “WEST15” in the name, the correct GET API request is D. GET https://intersight.com/api/v1/server/Profiles?$select=Name &$filter=startswith(Name, ‘WEST15’). This request filters the server profiles to only those that start with “WEST15”. For updating the name, option E is correct. The BODY = {” Name”: sp_name.replace(‘WEST15’,’LXT14’)} uses the Python replace method to change “WEST15” to “LXT14” in the server profile name. References: Cisco Intersight API documentation and Python programming resources.
