Cisco NX-OS PowerOn Auto Provisioning uses DHCP to provide initial addressing, gateway, DNS, and boot-script location information. The switch then contacts a TFTP or HTTP server to download the Python configuration script. Therefore, the configuration script must be deployed on the TFTP server. The DHCP server supplies the script location but does not normally host or execute the script itself. Software images and final configuration files can reside on one or more file servers referenced by the Python script, so placing the image on a TFTP server may also be part of the complete design. However, the action specifically required to execute the Python-based POAP workflow is hosting the configuration script on TFTP. Cisco’s POAP requirements explicitly identify a TFTP server containing the configuration script used to automate image installation and configuration. Cisco POAP requirements

The correct answer is C. standby supervisor.

From the exhibit, the command output clearly shows:

Module 6 SUP Yes disruptive Module Upgradable and later confirms:

Module 6 EPLD upgrade is successful and 6 SUP Success.

This indicates that the EPLD upgrade was performed on a Supervisor (SUP) module, specifically module 6. In Cisco MDS 9700 architecture, supervisor modules operate in a redundant pair (active and standby). When EPLD upgrades are performed, Cisco best practice and system behavior typically upgrade the standby supervisor first, because it allows the system to maintain control-plane continuity and minimizes disruption.

The output does not mention PSU, fan, or fabric modules, eliminating options A, B, and D. The explicit reference to SUP confirms that the upgrade applies to a supervisor module.

Thus, based on the module type shown in the output and standard Cisco upgrade behavior, the EPLD upgrade is applied to the standby supervisor, making C the correct answer.

A switch with only one supervisor has no redundant supervisor available to maintain control-plane operation while the active supervisor reloads. Even when the selected upgrade mechanism is described as nondisruptive, the absence of supervisor redundancy means that the switch cannot provide a seamless stateful supervisor switchover. The switch therefore experiences an interruption during the reload. Option B is impossible because the platform has no standby supervisor. Option A incorrectly assumes that the nondisruptive upgrade designation overrides the physical redundancy requirement. Although some line-card forwarding behavior can vary by platform and upgrade path, a single-supervisor reload cannot provide the same continuity as a dual-supervisor system. The effect is also broader than merely losing the management interface because the only supervisor is responsible for essential system control functions. Redundant supervisors are required for fully nondisruptive supervisor switchover behavior.

NX-API Sandbox is an interactive development utility that allows an administrator to enter familiar NX-OS CLI commands and view the corresponding API request and response structures. It can generate example code and display message formats such as XML and JSON, making it appropriate for translating traditional CLI operations into programmatic requests. JSON-RPC is an API message protocol, not the interactive translation and code-generation utility requested. Guest Shell supplies a Linux container in which scripts and tools can run, but it does not itself translate CLI commands into XML or JSON requests. Open NX-OS describes the broader programmability architecture and open interfaces available in NX-OS rather than a specific translation utility. Therefore, NX-API Sandbox is the tool that directly satisfies both the CLI translation and code-generation requirements on the Nexus platform.
