Cisco Certified Field Technician (CCT) 800-150 Cisco Study Notes

The main advantage ofCisco Intersightis itscloud-based architecture, which allows IT administrators tomanage infrastructure from any locationwithout needing to install or maintain traditional on-premises management tools.

This provides:

Centralized visibility and control over UCS servers and HyperFlex infrastructure

Remote firmware upgrades and configuration

Policy-driven automation

Unlike on-premises tools, Intersight eliminates the overhead of maintaining dedicated infrastructure for management.

For standalone Cisco Secure Firewall deployments, theCisco Secure Firewall Device Manager (FDM)is the most appropriate management option. FDM is a browser-based, on-box management tool that allows administrators to configure and manage a single firewall device without the need for external management infrastructure. It provides an intuitive interface for basic configurations, policy management, and monitoring.​

In contrast:​

Cisco Secure Firewall Management Center (FMC)is designed for centralized management of multiple firewall devices.

Cisco Defense Orchestrator (CDO)is a cloud-based solution for managing security policies across various devices.

Cisco Security Manageris an older platform primarily used for managing ASA devices.​

Theshow inventorycommand is used on Cisco devices to display detailed information about thehardware components installed, including:

Product Identifier (PID)

Version Identifier (VID)

Serial Number (SN)

Description of the component

In the exhibit, the output clearly shows:

NAME: "Chassis", DESCR: "Cisco ISR4451-X/K9"

PID:ISR4451-X/K9, VID: V01, SN: FCW2134L0SH

This confirms thatshow inventoryis the correct command to retrieve theserial numberand hardware inventory details.

show versionprovides some system information and sometimes includes serial numbers, but it's not as reliable or detailed for component-level hardware info.

show idpromis not commonly used and not supported on all platforms.

show platformprovides platform-specific info but not typically the serial number.

The highlighted components in all three Cisco UCS server models (5108 B-Series Blade Server Chassis, X9508 X Series Modular Server Chassis, and C225 M6 Rack Server) are fan modules, which are field-replaceable units responsible for cooling the system.

The highlighted components in the images correspond tocooling fans— these are essential for maintaining optimal thermal conditions within each Cisco UCS server type.Here's a breakdown of what's visible in each:

Cisco UCS 5108 B-Series Blade Server Chassis: The highlighted vertical rectangular components arefan modules, which provide high-efficiency airflow for the densely packed blades.

Cisco UCS X9508 X-Series Modular Server Chassis: The front-facingfan traysare clearly marked, used to cool the modular nodes and shared infrastructure.

Cisco UCS C225 M6 Rack Server: The highlighted components on the side of the motherboard are alsofan modules, directly responsible for cooling the CPU, memory, and other internal components.

These fans arefield-replaceable units (FRUs)and are routinely accessed by technicians during preventive maintenance or fault replacement.
