A network engineer plans to upgrade the firmware of a Cisco UCS B-Series chassis by using the Auto Install feature. Which component is upgraded during the infrastructure firmware upgrade stage?

The correct answer is C. I/O module. Cisco UCS Auto Install firmware upgrade is divided into two distinct stages. The infrastructure firmware stage upgrades fabric-level components: Fabric Interconnects (FIs) and I/O modules (IOMs, also called FEX modules). These are chassis/fabric infrastructure components.

Explanation

Cisco UCS Auto Install firmware upgrade is divided into two distinct stages. The infrastructure firmware stage upgrades fabric-level components: Fabric Interconnects (FIs) and I/O modules (IOMs, also called FEX modules). These are chassis/fabric infrastructure components. The blade firmware stage (server firmware upgrade) handles server-side components: BIOS, Cisco IMC (Integrated Management Controller), adapters, and storage controllers. This separation allows the fabric infrastructure to be updated independently from the compute nodes, minimizing disruption. Since the question asks specifically about the infrastructure stage, I/O modules (option C) is correct.
