Free Practice Questions for Cisco 800-150 Exam

These command associations are part of Cisco IOS essentials taught in FLDTEC's "Device Configuration and Verification" topic. Here's how each command functions:

show running-config

Displays the active configuration stored in RAM.

This command is used to verify the current settings on a Cisco device.

copy running-config startup-config

Saves the current running configuration to NVRAM, ensuring the configuration persists after a reboot.

This is critical after making changes to devicesettings.

copy tftp: running-config

Loads a configuration from a TFTP server and applies it to the current running configuration.

Often used during remote device setup or restoration.

copy usbflash0:backup.cfg running-config

Restores a saved configuration file from a USB drive.

Useful in field operations where physical backup media is used during maintenance.

These tasks are routine for field technicians performing configuration backups, restorations, and diagnostics in Cisco environments.

Cisco Webex Callingis a cloud-based, enterprise-grade PBX (Private Branch Exchange) solution designed to provide comprehensive voice communication services via the Webex cloud platform. It enables IP phones and softphones to register to the cloud, allowing for centralized call control, voicemail, and collaboration features without the need for an on-premises call manager.

Cisco Hosted Collaboration Solutionsare partner-hosted services.

Webex Meetingssupports virtual video conferencing.

Webex Teams(now part of Webex App) supports messaging and collaboration, not PBX functionality.

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.

Theprimary reasonfor placing heavier equipment, such as UPS units or core switches, at thebottom of a rackis tomaintain stability. A lower center of gravity reduces the risk of tipping, especially when the rack is not yet bolted or braced.

This is a standard safety precaution in network hardware installation and is particularly important when racks are being serviced or relocated.

Before installing or replacingDIMMs (Dual In-line Memory Modules)in a Cisco UCS server, it is essential to verify thecurrent DIMM configuration and the population order. Cisco UCS servers have strict memory population rules to ensure optimal performance and compatibility, particularly in relation to memory channels and banks.

While the type, capacity, and firmware compatibility are important, failing to follow the correct population guidelines can result in failed boot processes or suboptimal performance.

Kickstart Image→ Specialized bootloader that initializes the hardware

System Image→ Contains the full NX-OS kernel and operating system

Global configuration command mode→ Provides access to the broadest range of commands that affect the device as a whole

EXEC command mode→ Allows for displaying device status and configuration information

This knowledge is covered underCisco IOS/NX-OS Software Basicsin the FLDTEC training:

Kickstart Image:Alightweight bootloader image that initializes hardware and launches the system image. It's comparable to ROMMON in traditional IOS devices.

System Image:Includes the full NX-OS operating system, services, drivers, and kernel required to run the device.

Global Configuration Mode:After entering privileged EXEC mode (enable), this mode allows changes to system-wide settings such as interfaces, routing protocols, and VLANs.

EXEC Mode:Has two levels—User EXECandPrivileged EXEC. User EXEC provides limited diagnostic commands, while Privileged EXEC allows more extensive system views (show commands, reload, etc.).

Understanding these layers is essential when maintaining or restoring NX-OS devices in field environments.

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 theFLDTEC course, underMaintenance and RMA Procedures, Cisco outlines a specific sequence for bringing up anE-Series server modulein an ISR router. The sequenceensures proper recognition, IOS compatibility, and network readiness:

Power up the router and server: Ensures both components are initialized and POST begins.

Verify that the router recognized the server: Use service-module commands or show platform to confirm server visibility.

Load a compatible Cisco IOS image onto the ISR: The IOS must support the E-Series module to provide integration and configuration functionality.

Connect the server to the network: Establish network connectivity for services, remote access, or deployment.

This structured approach is essential for minimizing errors duringmodular hardware upgrades or RMAsin the field.

Cisco MDS switches are segmented into two key categories: Director-Class and Fabric Switches, each tailored for different SANenvironments:

Director-Class Switches (e.g., Cisco MDS 9700 Series):

Modular and highly scalable

Support hot-swappable components (line cards, supervisors, fabric modules)

High port density and performance for core SANs in enterprise data centers

Fabric Switches (e.g., Cisco MDS 9148T):

Compact, fixed-form factor

Best suited for smaller SANs or edge locations

Cost-effective and simple to deploy

This distinction is important when selecting hardware for data center core vs access layers in SAN architectures.
