Question 540 SSH from a management jump host succeeds, but attempts from user VLANs also reach the router despite a policy forbidding them. Which lasting design or operational safeguard best prevents this particular issue from recurring? Classify management-file transfers and default to encrypted protocols in automation templates. Standardize secured backup transport and include actual transfer tests rather than ping-only checks. Include secure management protocol activation and certificate lifecycle in router hardening templates. Maintain a controlled management-source allowlist and test it on new devices. ExplanationCorrect Answer D:Maintain a controlled management-source allowlist and test it on new devices. This addresses the recurring cause: VTY access-class policy governs which source networks may establish remote management sessions. A targeted acceptance check is: Confirm permitted jump-host access and denied test connections from a user subnet.

Question 541 An engineer enables an HTTPS device GUI but sees only HTTP active after importing certificates; users are warned about cleartext access. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Enable and validate the device's HTTPS secure server service while disabling the unnecessary HTTP service. Verify SCP server capability and enable the supported SCP service with the required authentication/authorization. Permit only the necessary TFTP transport flow between the approved endpoints or use a secure alternative. Configure an appropriate local user with secret and privilege or bind the approved AAA method list. ExplanationCorrect Answer A:Enable and validate the device's HTTPS secure server service while disabling the unnecessary HTTP service. A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP. Verify successful HTTPS with expected certificate and refusal of insecure HTTP on the management interface. Other Answers B:Verify SCP server capability and enable the supported SCP service with the required authentication/authorization. A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP. C:Permit only the necessary TFTP transport flow between the approved endpoints or use a secure alternative. A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP. D:Configure an appropriate local user with secret and privilege or bind the approved AAA method list. A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP.
Question 542 An engineer enables an HTTPS device GUI but sees only HTTP active after importing certificates; users are warned about cleartext access. Which technical mechanism best explains the behavior observed in this scenario? Console and VTY line settings are separate management entry points, so local console success does not prove remote line configuration. A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP. SCP rides over SSH but its server-side file-transfer capability can require distinct feature activation and privilege. TFTP uses UDP exchanges and data ports that do not behave like a single persistent TCP session. ExplanationCorrect Answer B:A certificate alone does not necessarily activate the secure HTTP management listener or disable plaintext HTTP. This explains why the initial condition produces the observed failure. The direct repair is: Enable and validate the device's HTTPS secure server service while disabling the unnecessary HTTP service. Validate through: Verify successful HTTPS with expected certificate and refusal of insecure HTTP on the management interface.
