800-150 Exam Dumps - Cisco Certified Field Technician (CCT) Questions and Answers

A → Power supply modules

B → Fan tray assembly

C → Line card slots 1 and 2

D → Supervisor modules

E → Line card slots 5, 6, and 7

The power supply units (A) are at the top, the fan tray (B) is a vertical module on the left, line cards (C and E) span multiple slots horizontally, and supervisor modules (D) are typically placed centrally for control functions.

In theFLDTEC courseunderCisco Modular Hardware Overview, the Cisco Catalyst 9400 series is broken down into clearly defined FRU zones:

Power Supply Modules (A):Located at thetop of the chassis, these provide redundant, hot-swappable power to the switch.

Fan Tray Assembly (B):Mounted vertically on the left, this ensures proper cooling and airflow throughout the chassis.

Line Card Slots 1 and 2 (C):Located in the upper section for network expansion.

Supervisor Modules (D):Positioned centrally, they handle control plane operations, management, and switching logic.

Line Card Slots 5, 6, and 7 (E):Lower slots for high-density port expansion.

Correct FRU identification ensures successful maintenance, upgrades, and hardware replacement during field operations.

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.

Cisco 8000Series routers are primarily designed for service provider and web-scale networks, offering high-performance routing capabilities to handle large-scale, high-bandwidth environments typically found in service provider infrastructures and data centers.

The Cisco 8000 Series routers are part of Cisco’s high-performance routing portfolio. As documented in the official Cisco product and FLDTEC study materials:

Cisco 8000 Series routers are purpose-built for service provider and cloud-scale datacenters.

They are designed to support massive bandwidth, 5G core, and edge routing demands.

These routers provide scalable, high-performance architecture, using Cisco Silicon One ASICs, enabling terabits of throughput with advanced telemetry and network programmability.

Why the other options are incorrect:

A. Remote branches and retail typically use ISR/ASR 1000/1100 Series.

C. Home or small business networks use Cisco RV Series or Meraki MX Series.

D. LAN access/distribution layers in campuses commonly use Catalyst 9000 Series switches or ISR routers, not high-end core routers.

The 8000 Series is typically found in service provider core, data center interconnect, and hyperscale cloud deployments (e.g., Google, Meta, AWS).

In theFLDTEC course, underSafety and ESD Procedures, Cisco outlines the following safety workflow before working on any network hardware:

Locate Emergency Power-Off Switch: Identifying how to cut power quickly is essential in case of an electrical fault or emergency.

Disconnect Power: Always ensure the power source is turned off and disconnected before handling any components.

Verify with Multimeter: Use a multimeter to confirm that no voltage is present before proceeding.

Connect ESD Strap: Once confirmed safe, attach your ESD strap to a grounded point to prevent electrostatic damage to sensitive components.

Following this process is critical not only forpersonal safetybut also forequipment protection, especially duringhardware installation, maintenance, or RMA replacements.

Theinstall allcommand is the standard method used to install or upgrade Cisco NX-OS software on Nexus switches. This command streamlines the installation process by automating tasks such as verifying the software image, checking for compatibility, and managing the installation of optional packages or SMUs (Software Maintenance Upgrades). It ensures a comprehensive and efficient upgrade process, minimizing the potential for errors.​Cisco

In contrast:​

copy tftp: running-configis used to copy configuration files, not software images.

install kickstartis an outdated command from earlier NX-OS versions.

boot systemsets the boot variable but does not handle the full installation process.​

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.

In a Class B network, the default subnet mask is 255.255.0.0, which allocates:​

16 bits for the network portion

16 bits for the host portion​

When the subnet mask is changed to255.255.255.0, it becomes:​

24 bits for the network portion

8 bits for the host portion​

This indicates that8 bitshave been borrowed from the host portion to create additional subnets. Borrowing bits allows for the division of the original network into smaller sub-networks, enhancing organization and security within the network.​

In ablade server environment, thechassisserves as the enclosure thathouses multiple blade servers. It provides shared power, cooling, and connectivity resources. Blade servers are compact server modules that insert into the chassis, and the shared infrastructure makes the entire system efficient in space, power, and management.

The chassis does not act as a switch or storage array itself but provides interconnects and sometimes integrated networking components.

Anon-premises deploymentmodel minimizes dependence on internet connectivity for core collaboration functions. In this model, all critical services, including call control, messaging, and conferencing, are hosted within the organization's local infrastructure. This ensures that internal communication services remain operational even if internet connectivity is lost.​

In contrast, cloud-based deployments (Options A and C) and Hosted Collaboration Solutions (Option D) rely on internet connectivity to access services hosted externally, making them more susceptible to internet outages.​

Cisco UCS E-Series serversare integrated, blade-style compute modules that can be installed insideCisco ISR(Integrated Services Routers). Their primary advantage is toprovide local compute resources in branch officeswithout needing a full data center environment.

This enables:

Hosting of virtual machines or applications locally

Reduced latency for edge computing

Lowered dependency on central data center resources

These servers are ideal for runningbranch-office workloads, virtualization, or edge analytics, allowing enterprises to deploy scalable compute capabilities closer to the data source.
