800-150 Cisco Supporting Cisco Devices for Field Technicians (FLDTEC) Free Practice Exam Questions (2025 Updated)

Cisco Room Kit→ All-in-one devices for personal workspaces and meeting rooms

Cisco Desk Series→ Standalone modular video conferencing systems

Quad Camera→ Multi-angle video capture for immersive experiences

Room Navigator→ Touch panel for room controls and scheduling

Cisco Board→ Interactive touchscreen displays supporting video conferencing

Cisco’s collaboration portfolio includes a wide variety ofhardware endpointsused toenhance remote communication and conference room experiences. These are highlighted in the FLDTEC material as follows:

Cisco Room Kit: Combines camera, codec, speakers, and microphones into one device — designed for easy integration with displays in meeting spaces.

Cisco Desk Series: Purpose-built for desktop video conferencing and modular setups.

Quad Camera: Offersautomatic speaker trackingandintelligent framing, used in large rooms for immersive experiences.

Room Navigator: Used tocontrol meetings, reserve rooms, and manage smart building functions.

Cisco Board: Interactive digital whiteboard that integratesvideo conferencing, whiteboarding, and wireless sharing.

In Cisco Room systems such as the Room Kit Pro and similar setups, replacing thequad camerainvolves a physical disassembly process. Specifically, theupper textile grille must be removedto gain access to the internal mounting mechanism. After that,release levers are used to disengage the quad camera unitfrom its housing.

This procedure ensures secure installation while allowing relatively straightforward removal when maintenance or replacement is necessary. The codec, loudspeaker, and antenna module do not typically require this specific removal method.

A speed mismatch occurs when two connected Ethernet devices are configured to operate at different speeds. In scenario A, one device is manually set to 1 Gbps, while the other is set to 100 Mbps. Since both ends are hard-coded to different speeds, they cannot successfully negotiate a common speed, leading to a mismatch and resulting in a failed or unstable link.​

In contrast, scenario B, where both ends are manually set to the same speed, ensures compatibility and stable communication. Scenario C can lead to a duplex mismatch rather than a speed mismatch; the auto-negotiating end may default to half-duplex if it cannot determine the duplex setting of the manually configured end. Scenario D is less common; if auto-negotiation fails, devices may revert to their lowest common speed, but this typically results in reduced performance rather than a complete mismatch.​

Cisco NX-OSis the operating system specifically developed forCisco Nexus series switches, which are widely used in modern data centers. NX-OS is optimized forscalability, high availability, and virtualization features.

It differs from IOS and IOS XE (used in traditional routers and switches) and IOS XR (used in carrier-grade platforms). NX-OS includes advanced features such as Virtual Port Channels (vPC), FabricPath, and integrated Layer 2/3 capabilities tailored for data center networks.

TheUCS Fabric Interconnectis the central management and communication hub of theCisco UCS (Unified Computing System)environment. It integrates compute, network, and storage access into a unified system.

Fabric Interconnects:

Manage all servers and I/O modules connected to the UCS domain

Provide connectivity and are the point of integration with the Cisco UCSManager

Offer high-availability and centralized policy management

Other options like the Nexus or MDS switches do not serve this unified management function in a UCS deployment.

Asubnet maskis a 32-bit number used in IP networking to divide an IP address into network and host portions. This division is crucial for routing traffic within and between networks. The subnet mask works in tandem with the IP address to identify which part of the address refers to the network and which part refers to the host. This distinction allows for efficient IP address allocation and routing.​

For example, in the IP address 192.168.1.10 with a subnet mask of 255.255.255.0, the first three octets (192.168.1) represent the network portion, while the last octet (10) identifies the specific host within that network.​

After upgrading the firmware on aCisco UCS C-Series serverusing theHost Upgrade Utility (HUU), it is critical toverify the update statusto ensure thatall targeted components(such as BIOS, CIMC, and RAID controller firmware) have beensuccessfully updated.

Firmware upgrades often involve multiple subsystems, and partial or failed updates can result in inconsistencies or even device instability. Verifying the update status allows the technician to identify any missed components and perform corrective actions if necessary.

Options like generating compliance reports, third-party application checks, or license activations are not the primary reasons for this verification step in the HUU process.

When connectingtwo devices of the same type(e.g., two routers, two switches, or two DTEs), acrossover cableis required. This cable swaps the transmit and receive pairs to allow direct communication between devices without the need for an intermediate device like a switch.

Straight-through cablesare used to connect different types of devices (e.g., PC to switch).

Rolled cablesare used for console access.

USB Type A to Bcables are typically used for peripheral device connections, not networking.

The highlighted component on the Cisco I/O module is the chassisconnections LED, which indicates the status of connectivity between the I/O module and the chassis.

In the exhibit, the orange arrow points to asmall rectangular LED indicatorlocated to the left side of the I/O module (Cisco UCS-IOM-2304). This specific LED isnot aligned with the ports, fans, or screws, which helps identify it correctly.

Chassis connections LED (B)is responsible for indicating thestatus of uplink/downlink communicationbetween the I/O module and the chassis.

Greenusually indicates a healthy link.

Amberoroffmay indicate a problem or no connection.

Why the other answers are incorrect:

A. Captive screw→ These are at the far corners, not where the arrow points.

C. Fan module LED→ This IOM doesn’t have user-visible fan LEDs atthe front face.

D. Fixed port→ These are the large rectangular SFP ports clearly visible in the middle, not near the arrow.

This identification is important whentroubleshooting chassis-to-IOM connectivityor verifyingmodule status LEDsduring field maintenance.
