Cisco 800-150 Exam With Confidence Using Practice Dumps

When connectingtwo devices of the same type(e.g., two routers, two switches, or two DTEs), acrossover cableis required. This cable swaps the transmit and receive pairs to allow direct communication between devices without the need for an intermediate device like a switch.

Straight-through cablesare used to connect different types of devices (e.g., PC to switch).

Rolled cablesare used for console access.

USB Type A to Bcables are typically used for peripheral device connections, not networking.

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.

===========

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.​
