A network technician has just installed a TFTP server on the administrative segment of the network to store router and switch configurations. After a transfer attempt
to the server is made, the process errors out. Which of the following is a cause of the error?
Only FTP can be used to copy configurations from switches
Anonymous users were not used to log into the TFTP server
An incorrect password was used and the account is now locked
Port 69 is blocked on a router between the network segments
The question states that the TFTP server is installed on the “administrative segment of the network”. This implies that the network has multiple segments (subnets)
and TFTP server is on a different network segment to other computers.
For a computer on one subnet to connect to a computer on a different subnet, a router is required to route traffic between the two subnets. Routers often include
firewalls so they can be configured to allow specific traffic to be routed between the subnets and block unwanted traffic.
TFTP uses UDP port 69. The most likely cause of the connection timeout error in the question is that the firewall has not been configured to allow traffic using UDP
