300-410 Question 258
Single answerAn enterprise network engineer needs to transfer a Cisco IOS image to a router using TFTP. The TFTP server is configured and reachable, but the transfer fails repeatedly. After examining the configuration, the engineer realizes that the issue is related to the lack of file permissions on the TFTP server directory. Which action should the engineer take to resolve the issue?
- A
Ensure that the TFTP server directory has write permissions enabled for all users.
- B
Restart the TFTP server to refresh the configuration.
- C
Use FTP instead of TFTP for the file transfer.
- D
Verify and enable UDP port 69 on the TFTP server.
Show answer and explanation
Correct answer: A
Explanation
TFTP servers need proper directory permissions to allow file operations such as reading and writing IOS images. Without the correct permissions, even if the TFTP server is reachable, the transfer will fail. Enabling write permissions on the TFTP server directory resolves this issue.
- A. Correct.
TFTP servers require appropriate permissions on their directories to allow file transfers. Enabling write permissions resolves the issue.
- B. Incorrect.
Restarting the TFTP server does not address the underlying issue of missing file permissions.
- C. Incorrect.
Switching to FTP is unnecessary as the issue is specific to the TFTP server's file permissions.
- D. Incorrect.
UDP port 69 is required for TFTP, but in this scenario, the issue is related to file permissions, not port availability.
