800-150 Exam Dumps : Supporting Cisco Devices for Field Technicians (FLDTEC)

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.

===========

After powering off a Cisco device in preparation for chassis replacement, theimmediate next stepis tolabel and remove all I/O cables. This step is crucial to ensure that all connections can be accurately restored after the new chassis is installed.​

Proper labeling prevents confusion and potential misconfigurations during reassembly. Only after all cables are safely disconnected should you proceed to remove the chassis ground and then the chassis itself.​
