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 :=

The output shown in the exhibit is a list of distinguished names (DNs) for Cisco Unified Computing System (UCS) blades within specific chassis. The correct PowerTool commands to provide this output would be those that retrieve information about UCS blade servers and then select their distinguished names. The command Get-UcsBlade | Select-Object Dn retrieves all the UCS blade servers and then pipes them to the Select-Object cmdlet to display only their distinguished names, which matches the pattern seen in the exhibit. Similarly, Get-UcsRackUnit | Select-Object Dn could potentially provide a similar output if rack units are named in a similar fashion to blades within the system’s naming conventions. References :=

 The network bootstrap program used by Cisco NX-OS for iPXE is called iPXE-POAP (Power-On Auto Provisioning). This process assists in automating the installation and configuration of Nexus switches. POAP automates the process of upgrading software images and installing configuration files on switches that are being deployed in the network for the first time. References: Cisco official documentation and training materials.

Kubernetes deployed with the ACI CNI plug-in offers Namespace Isolation and Cluster Isolation. Namespace Isolation segregates resources within the same cluster using Kubernetes namespaces, while Cluster Isolation ensures complete separation between different clusters. References:

To access the REST API browser within Cisco UCS Director, one must enable the Developer menu from the Cisco UCS Director interface. After enabling this option, select ‘Orchestration’ and then choose ‘REST API Browser’. This allows users to interact with the various APIs provided by Cisco UCS Director for automation and orchestration purposes. References: Cisco UCS Director REST API Guide
