Question 760
At the Highland government office, R-HIG-RT1 cannot complete a TFTP image retrieval; the team keeps changing SSH passwords even though the TFTP server's UDP reachability is blocked. Which continuing operational control is most directly relevant to preventing this problem?
Explanation
Correct Answer
The safeguard follows the failure mechanism at the Highland government office. Validate transfer protocol, path and access-control requirements before change windows.
Incorrect Answers
This is useful for another concern: Back up authorized management identity configuration and validate SSH after device recovery. It does not continuously test tftp reachability versus credentials at the Highland government office.
This would manage a different failure pattern. SNMPv3 authentication or privacy negotiation fails because the peers' user security settings differ. It is not the most direct recurring check for tftp reachability versus credentials at the Highland government office.
That safeguard protects against vty ssh transport restriction, not the concrete risk described at the Highland government office. The TFTP transfer path is unavailable or disallowed; SSH authentication is unrelated to TFTP reachability.
