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 theFLDTEC curriculum, technicians are trained on physical tools essential for support in the field. These tools and their uses are explained as follows:

Flash Card Reader:Used with removable CompactFlash cards commonly found in older Cisco routers and switches. These cards hold the IOS image or config files.

USB Thumb Drive:Used for transferring IOS files or configs directly to and from Cisco devices that support USB storage. Convenient for portable backups.

RJ-45 Ethernet Loopback Connector:A diagnostic tool that loops the signal back into the port. Helps verify port functionality by simulating a live Ethernet connection.

RJ-45 Coupler:Allows two patch cables to be connected, effectively extending the reach of a cable — useful in setups where a single cable is not long enough.

Theboot systemcommand is used in globalconfiguration mode to specify the source and filename of the Cisco IOS software image that should be loaded during the device’s boot process. This command ensures that the device loads a specific IOS image, whether it's stored locally in flash or fetched from a TFTP server.

Syntax example:

boot system flash:c1900-universalk9-mz.SPA.157-3.M3.bin

boot image,boot ios, andboot sourceare invalid or non-existent in standard Cisco IOS.

The commandcopy tftp: running-configis used to retrieve a configuration file from a TFTP server and merge it with the current running configuration of a Cisco device. Thisoperation is additive, meaning it integrates the new configuration commands into the existing running configuration without removing any pre-existing commands unless explicitly overridden.​

This method is particularly useful when restoring configurations to a replacement device, as it allows for the seamless integration of necessary settings without disrupting the current operational state.​

In contrast, usingcopy tftp: startup-configwould overwrite the startup configuration file, which could lead to unintended consequences upon the next device reload. The optionsload tftp: running-configandmerge tftp: running-configare not valid Cisco IOS commands.​

Theserial numberfor Cisco switches is typically found on a label located on therear panel near the power supplies. This positioning allows technicians to quickly access identification information even when the device is not powered on.

This label is essential for inventory tracking, RMA procedures, and registration for support. Serial numbers are not typically placed on the top or bottom surfaces for devices mounted in a rack, as those areas are less accessible.

TheCisco Catalyst 9000 Seriesis engineered to address the evolving needs of modern enterprise networks by integrating the functionalities of both the core and distribution layers into a unified, converged architecture. This series offers advanced capabilities such as high-speed data forwarding, enhanced security features, and support for automation and programmability, making it suitable for scalable and efficient network designs.​

The Catalyst 9000 Series includes models like the Catalyst 9500 and 9600, which are optimized for core and distribution roles, providing high throughput and reliability. These switches support advanced features like Software-Defined Access (SD-Access) and are designed to meet the demands of cloud-scale and security-focused environments.​

In contrast, theMeraki MS400 Series(Option A) is tailored for cloud-managed aggregation and lacks the comprehensive feature set required for core functionalities. TheCatalyst 6500 E-Series(Option B), while historically significant, is considered a legacy platform and may not support the latest advancements in network convergence. TheCatalyst 1300 Series(Option C) is designed for small to medium-sized businesses and is not intended for core or distribution layer deployments.​

Before shutting down any Cisco collaboration device (such as an IP phone, video endpoint, or codec) for replacement, it is essential toback up the configuration. This ensures that all custom settings, including user profiles, network configurations, and service settings, are preserved and can be quickly restored on the replacement device.

This backup minimizes downtime and avoids manual reconfiguration errors during the swap process.

After disconnecting the network cable from an SFP transceiver, theimmediate next step is to reinstall the dust plugsinto the optical bores. This action prevents contamination from dust or debris that can damage the optical interfaces or degrade performance.

It’s important to protect the exposed optical port before handling the rest of the transceiver module. Dust plugs help maintain the integrity of the component until a new cable or module is connected.

NVRAM → Startup configuration

RAM → Running configuration

ROM → Bootstrap code, POST code, ROM monitor

Flash memory → Cisco IOS software, backup configuration

Each memory type in a Cisco device serves a specific function in the boot process and runtime operation. NVRAM retains configuration across reboots, RAM is volatile and holds active configs, ROM handles initial boot tasks, and flash stores the operating system.

This content is covered thoroughly in"Cisco Equipment and Related Hardware"in the FLDTEC curriculum. Here's the breakdown:

ROM (Read-Only Memory)

Stores bootstrap code, POST (Power-On Self-Test), and ROM Monitor.

These are essential for the device’s initial power-on operations and recovery modes.

NVRAM (Non-Volatile RAM)

Holds thestartup configuration file, which is loaded during the boot process.

Content remains intact after a reboot or power cycle.

RAM (Random Access Memory)

Stores therunning configurationand current operational state of the router or switch.

Also used for routing tables, ARPcache, and packet buffers.

Data is lost when the device is powered off or rebooted.

Flash Memory

Contains theCisco IOS image, system files, and can storebackup configurations.

It is a non-volatile storage, so it retains data after reboots.

Within theFLDTECtraining, especially underMaintenance and RMA Procedures, there is a strong emphasis on safely transferring and adapting configurations from failed or decommissioned devices to replacement units.

The official guidance includes the following:

"When reusing a configuration from an old device, make sure to retain the necessary security elements such as username entries. This ensures the replacement device is still accessible under the correct user credentials."

Here's a breakdown of why the correct answer isB:

A. Remove all configurations under line vty 0 4:This would eliminate remote access settings, making it harder to manage the device.

B. Retain all username entries:Correct. Keeping the username entries ensures continued secure access and avoids loss of administrative control.

C. Keep all access-list commands intact:Not always required — ACLs are often tailored to interface-specific settings or environments which may differ between devices.

D. Add the enable password cisco command:Not a best practice. Default passwords (like cisco) should be avoided for security reasons, and it's not required if enable secret is already in use.
