Configure high-performance compute and storage to support AI workloads using Cisco UCS

Short answer

C Adding an OS image to the software repository and adding a server configuration utility to the software repository.

Question

A data center administrator for a medium-sized manufacturing facility uses Intersight to perform unattended operating system installation on already discovered X-Series servers with server profiles assigned. Which set of prerequisites must be met for installing an operating system on a server in Cisco Mode?
  1. configuring a firmware policy adding an operating system configuration file to the software repository
  2. adding an OS image to the software repository adding an operating system configuration file to the software repository
  3. adding an OS image to the software repository adding a server configuration utility to the software repository Correct Answer
  4. configuring a virtual KVM policy adding a server configuration utility to the software repository

Key Takeaways

The question tests knowledge of Cisco Mode's unique requirement for a Server Configuration Utility (SCU) alongside the OS image, distinct from UEFI Mode which may use different mechanisms.

This page explains the specific prerequisites for performing unattended operating system installation on Cisco X-Series servers using Intersight in Cisco Mode, highlighting the required repository components.

Common mistake: Candidates often select options involving firmware policies or virtual KVM policies, failing to recognize that Cisco Mode specifically mandates the Server Configuration Utility (SCU) for boot and installation.

Expert Analysis

Why the Answer Is Correct

In Cisco Mode within Cisco Intersight, unattended OS installation relies on the Server Configuration Utility (SCU) to handle the boot process and OS deployment. Therefore, both the OS image itself and the SCU must be present in the software repository. This ensures that the server can boot into the utility environment and then proceed with the silent installation of the guest OS.

Why the Other Options Are Wrong

Option A is incorrect because a firmware policy does not directly facilitate OS installation; it manages BIOS/UEFI settings. Option B is incomplete as it omits the critical SCU component required by Cisco Mode. Option D is wrong because virtual KVM policies are used for remote console access, not for the automated OS installation pipeline.

Community Comment Notes

Community consensus strongly supports Option C, with users noting that 'Cisco Mode' specifically distinguishes itself by requiring the Server Configuration Utility (SCU). As one commenter noted, 'The distinguishing detail is "Cisco Mode." In Intersight's unattended OS install, Cisco Mode uses the Server Configuration Utility (SCU) image to drive the installation.' This confirms that the presence of the SCU is the key discriminator.

Exam Strategy

When dealing with Intersight OS deployment questions, always check if the mode is specified. If it is 'Cisco Mode', look for the Server Configuration Utility (SCU) in the answer choices. If it is 'UEFI Mode', the requirements might differ, often relying on iPXE or other standard boot methods.

Frequently Asked Questions

Why is SCU required for Cisco Mode?

SCU provides the necessary boot environment and drivers to automate the OS installation process on Cisco X-Series servers without user intervention.

What is the difference between Cisco Mode and UEFI Mode?

Cisco Mode uses the SCU for automated deployment, while UEFI Mode typically relies on standard network boot protocols like iPXE to load the OS installer.

    The answer is C: adding an OS image to the software repository + adding a server configuration utility to the software repository. The distinguishing detail is "Cisco Mode." In Intersight's unattended OS install, Cisco Mode uses the Server Configuration Utility (SCU) image to drive the installation — so the repository needs both the OS image and the SCU.

    The key clue is "Cisco Mode". The Intersight OS Installation process requires: 1- An OS Image (ISO) 2- A Server Configuration Utility (SCU) image for unattended installations and customization/tracking capabilities.
