Retrieving Updated Firmware for Network Switches

A network technician is performing a firmware upgrade on a switch.

The firmware needs to be downloaded to the device.

Which of the following methods should the technician use to retrieve the updated firmware?

A.

RDP

B.

SSH

C.

TFTP

D.

Telnet.

C.

Sure, I'd be happy to explain!

When performing a firmware upgrade on a switch, the updated firmware needs to be downloaded to the device. To retrieve the updated firmware, the most appropriate method to use would be TFTP (Trivial File Transfer Protocol).

TFTP is a simple file transfer protocol that is commonly used to transfer firmware updates to network devices such as switches and routers. It is a lightweight protocol that does not provide authentication or encryption, but it is useful for transferring firmware and configuration files quickly and efficiently.

RDP (Remote Desktop Protocol) is a protocol used to remotely control a computer or device. It is not a file transfer protocol, so it would not be appropriate for downloading firmware to a switch.

SSH (Secure Shell) is a network protocol that provides secure access to a remote device. Like RDP, it is not a file transfer protocol, so it would not be appropriate for downloading firmware to a switch.

Telnet is an older network protocol that is used to provide remote access to a device. However, it is not secure and has largely been replaced by SSH. Like RDP and SSH, it is not a file transfer protocol, so it would not be appropriate for downloading firmware to a switch.

So, the correct answer is C. TFTP.
