Cisco Updated 800-150 Exam Questions and Answers by taran

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.

InInstall mode, thepackages.conffile plays a crucial role in the boot process of Cisco IOS XE Software. It specifies the list of software packages to be loaded and the sequence in which they should be initialized during system startup. This file ensures that all necessary components are correctly loaded, providing a modular and flexible approach to software management.​

Contrary to the other options:​

Thepackages.conffile does not extract the bin file; it references already extracted packages.

It does not contain the entire bundled image; that's characteristic of Bundle mode.

While it resides in the flash memory, it is not a subdirectory but a configuration file.​

Cloud-based managementis a core feature of Cisco Merakiswitches and significantly simplifies the device replacement process. When a failed switch is replaced:

The new hardware can be claimed in the Meraki dashboard.

The previously assigned configuration is automatically applied to the replacement device.

This eliminates the need for local reconfiguration and ensures continuity with minimal manual effort.

This centralized approach ensures that configurations are stored securely and consistently applied across devices.

To apply a prewritten configuration to a new Cisco device, the console terminal must be inGlobal Configuration Mode. This mode allows administrators to enter configuration commands that affect the device's overall operation. To access Global Configuration Mode, one must first enter Privileged EXEC Mode by typingenable, and then enterconfigure terminal. Once in Global Configuration Mode, theprewritten configuration can be pasted, and the device will accept the commands accordingly.​
