Free Practice Questions for Cisco 800-150 Exam

Right-To-Use (RTU) licensesare locally managed licenses that allow users to activate specific features on Cisco devices without the need for external tools or connectivity to Cisco's licensing infrastructure. These licenses operate on an honor-based system, where the user agrees to comply with the licensing terms without mandatory enforcement mechanisms.​

In contrast:​

Hybrid licensescombine aspects of traditional and smart licensing models.

PAK (Product Authorization Key) licensesrequire registration and activation through Cisco's licensing portal.

Smart licensesnecessitate communication with Cisco's Smart Licensing servers for activation and management.​

In enterprise networking, remote sites or branch offices connect to the central campus network using:​

WAN Links:These are dedicated communication paths that connect geographically dispersed networks. WAN links can be leased lines, MPLS circuits, or other forms of long-distance connectivity that facilitate reliable data transmission between remote sites and the main campus.​

IPsec VPN Tunnels:Internet Protocol Security (IPsec) VPNs provide secure, encrypted tunnels over the public internet, allowing remote sites to connect to the enterprise network securely. This method is cost-effective and widely used for connecting branch offices to the central network infrastructure.​

Access layer switches (Option A) and LAN core switches (Option E) are components within a local network and do not facilitate remote connectivity. Ad hoc Wi-Fi networks (Option D) are temporary and lack the security and reliability required for enterprise-level remote connections.​

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.

On Cisco Catalyst 8000 Series Edge platforms, removing the chassis cover provides access to internal components such asDIMMs (Dual In-line Memory Modules)andSSDs (Solid-State Drives). These components are located internally and require the removal of the chassis cover for maintenance or replacement.​

DIMMsare used for system memory and are essential for the router's operation.

SSDsprovide storage for system software and configurations.​

Other components likeNetwork Interface Modules (NIMs)andtransceiversare typically accessible externally and do not require chassis cover removal.​

In theFLDTEC curriculum, Cisco emphasizes understanding of virtualized components in enterprise networks and UCS environments:

Virtual Switch– Operates within a hypervisor, replicates L2 behavior for inter-VM and external connectivity.

Type 1 Hypervisor– Also called “bare-metal,” examples include VMware ESXi and Microsoft Hyper-V Core; optimized for data center performance.

Virtual Machine (VM)– A logical instance of a system that runs its own OS and apps, powered by virtualized CPU, RAM, and storage.

Type 2 Hypervisor– Runs atop an existing OS (e.g., VMware Workstation, VirtualBox), ideal for labs and dev/testing.

Mastering these definitions supports field technicians inUCS deployments, virtualization troubleshooting, and remote infrastructure diagnostics.

This procedure is taught in theFLDTEC courseunder theDevice Configuration and Verificationsection and reflects standard field technician workflows:

Connect to the console portusing a console cable and terminal software (like PuTTY or Tera Term).

Access the CLIof the Cisco device by logging in via the console session.

Create a log fileor enable logging in the terminal emulator to begin capturing output.

Check the router statususing commands such as show running-config, show ip interface brief, or show version.

Save the output filefrom the terminal emulator for documentation, troubleshooting, or escalation.

This logical flow ensures accurate diagnostics and traceability during field support operations.

TheWireless LAN Controller (WLC)plays a central role in Cisco’s Unified Wireless Network solution by providing centralized management, configuration, and monitoring for multiple access points (APs). It allows for streamlined policy enforcement, seamless mobility, load balancing, and security management across wireless networks.

While WLCs facilitate wireless connectivity indirectly, their main role is tocentrally manage and controlaccess points — not to function as Layer 3 routers or format data frames.

According to theCisco FLDTEC training and product documentation:

Cisco PTZ 4K Camera: Offers high-definition video capture with pan-tilt-zoom features and 4K resolution — ideal for large conference spaces.

Cisco Webex Board Pro: Interactive collaboration device that combines video conferencing, whiteboarding, and wireless content sharing.

Cisco Quad Camera: Features multiple cameras for wide-angle views, speaker tracking, and automatic framing — great for medium to large meeting rooms.

Cisco Room Navigator: A touchscreen device that provides intuitive control for room settings, scheduling, and call management.

Component to configure→ interface

Interface type→ FastEthernet

Port→ 1

Slot→ 0

This command structure is part of theDevice Configuration and Verificationsection in the FLDTEC course. It teaches how to navigate and configure interfaces on Ciscodevices using the IOS CLI:

interface is the global configuration mode command to begin configuring a network interface.

FastEthernet specifies thetype of interface(could also be GigabitEthernet, Serial, etc.).

0/1 represents theslot/portstructure used on Cisco devices:

The first digit (before the slash) is theslot number.

The second digit (after the slash) is theport numberwithin that slot.

This structure allows Cisco to modularly address interfaces, especially in devices with multiple slots or module-based configurations.

In theInfrastructure as a Service (IaaS)model, the cloud provider is responsible for managing and maintaining the underlying infrastructure components, including:

Networking: The cloud provider handles all aspects of network configuration, hardware, and virtual networking.

Storage: The cloud provider supplies and manages the physical and virtual storage infrastructure required to support the consumer’s data needs.

The customer is responsible for managing:

Operating Systems

Applications

Data

This model offers flexibility while shifting infrastructure maintenance responsibilities to the service provider.
