TCP provides reliability through acknowledgments and retransmission. TFTP is a lightweight file-transfer protocol that runs over UDP on port 69 and typically does not use authentication. In Cisco environments, TFTP is commonly used for simple image and configuration transfers during boot or recovery workflows, while FTP is the reliable TCP-based option.\n\n**Learn more:** [RFC 959 – File Transfer Protocol (FTP)](https://www.rfc-editor.org/rfc/rfc959) · [RFC 1350 – The TFTP Protocol](https://www.rfc-editor.org/rfc/rfc1350)"} reuse={false} />

The current ordering is wrong. The correct answers are: FTP uses ports 20 and 21 over TCP by default and is more reliable for loading IOS images TFTP uses port 69 and UDP by default and does not require user credentials TFTP is appropriately named for being simple to configure and use. It is less reliable and you may often see failures or bad hashes when loading files or images instead of using FTP.

Correct.

Answers are wrong! ND: the Answers has to be in the correct order otherwise the system will mark you incorrect

Y como sabe el software si están o no en orden las respuestas?... Creo que lo importante es la respuesta o respuestas y no el orden de las mismas

FTP: PROVIDE REALIBILITY, PORT 20 21, TCP TFTP: DOESN'T AUTHEN, PORT 69, UDP FTP: - PORT 20 :create connect to client, receive request client - PORT 21: transfer data to client

TFTP gives reliability when loading an IOS image upon boot up. FTP can be used for IOS image transfers after the device has booted.

Do the answers have to be in a particular order to be considered correct?

yes this is correct! I googled it.

Looks like everybody is wrong on this one. I double checked with google and chatgpt to make sure I had it right because none of it made any sense when I looked at it. Should be TCP Uses Ports 20 and 21 IOS Image UDP Uses Port 69 Does not require User Auth You always want the protocol FIRST to start the connection FIRST, THEN the port, etc.

The trickiest item is "provides reliability when loading an IOS image upon boot up" — this goes to TFTP, not because TFTP itself is reliable (it's UDP), but because it's the protocol Cisco devices specifically use during the boot/ROMMON process to load IOS images from a TFTP server. It is not FTP
