Question 560 A router's FTP backup script stores configuration files in cleartext on an untrusted transit network, conflicting with an encryption requirement. Which lasting design or operational safeguard best prevents this particular issue from recurring? Include secure management protocol activation and certificate lifecycle in router hardening templates. Add SCP service checks to configuration-backup automation acceptance. Ban insecure VTY transports and audit remote-access protocol settings regularly. Classify management-file transfers and default to encrypted protocols in automation templates. ExplanationCorrect Answer D:Classify management-file transfers and default to encrypted protocols in automation templates. This addresses the recurring cause: Traditional FTP exposes control credentials and file contents unless specifically protected by a secure variant. A targeted acceptance check is: Verify a complete backup over the encrypted transport and review captured packets for exposed credentials. Other Answers A:Include secure management protocol activation and certificate lifecycle in router hardening templates. Traditional FTP exposes control credentials and file contents unless specifically protected by a secure variant. B:Add SCP service checks to configuration-backup automation acceptance. Traditional FTP exposes control credentials and file contents unless specifically protected by a secure variant. C:Ban insecure VTY transports and audit remote-access protocol settings regularly. Traditional FTP exposes control credentials and file contents unless specifically protected by a secure variant.
Question 561 An SNMPv2c monitor can poll a router using a public community from a broad subnet, violating the organization's network-management policy. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Replace broad community access with restricted SNMPv3 credentials and management-source controls where supported. Bind the SNMPv3 user to an appropriately restricted read view and avoid write access. Check the enabled notification types, receiver configuration and trap source interface. Align the sender's notification user, security level and receiver's accepted identity. ExplanationCorrect Answer A:Replace broad community access with restricted SNMPv3 credentials and management-source controls where supported. SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. Poll authorized OIDs as an SNMPv3 user while unauthorized community and source tests fail. Other Answers B:Bind the SNMPv3 user to an appropriately restricted read view and avoid write access. SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. C:Check the enabled notification types, receiver configuration and trap source interface.

Question 562 An SNMPv2c monitor can poll a router using a public community from a broad subnet, violating the organization's network-management policy. Which technical mechanism best explains the behavior observed in this scenario? SNMPv3 notifications are subject to the receiver's user/security-level validation independent of network transport. SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. SNMP views and group permissions distinguish readable OIDs from writable management operations. SNMP polling and event notifications use different initiation paths; a working GET does not prove traps are enabled. ExplanationCorrect Answer B:SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. This explains why the initial condition produces the observed failure. The direct repair is: Replace broad community access with restricted SNMPv3 credentials and management-source controls where supported. Validate through: Poll authorized OIDs as an SNMPv3 user while unauthorized community and source tests fail. Other Answers A:SNMPv3 notifications are subject to the receiver's user/security-level validation independent of network transport.

Question 563 An SNMPv2c monitor can poll a router using a public community from a broad subnet, violating the organization's network-management policy. After applying the correction, which verification evidence most directly demonstrates that this issue is resolved? Validate matching engine ID and a successful SNMPv3 request after reprovisioning users. Confirm approved GET operations succeed and an unauthorized SET operation is rejected. Poll authorized OIDs as an SNMPv3 user while unauthorized community and source tests fail. Check accepted traps with matching SNMPv3 security identity and no unknown-user errors. ExplanationCorrect Answer C:Poll authorized OIDs as an SNMPv3 user while unauthorized community and source tests fail. This checks the affected traffic or control-plane behavior, not merely a generic up/down indicator. The underlying mechanism is: SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. Other Answers A:Validate matching engine ID and a successful SNMPv3 request after reprovisioning users. SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections. B:Confirm approved GET operations succeed and an unauthorized SET operation is rejected.

Question 564 An SNMPv2c monitor can poll a router using a public community from a broad subnet, violating the organization's network-management policy. Which lasting design or operational safeguard best prevents this particular issue from recurring? Use read-only management identities by default and review SNMP write privileges. Maintain a joint inventory of sender/receiver SNMPv3 notification credentials. Include event-trap functional tests in monitoring onboarding. Use SNMPv3 authPriv and least-privilege source scoping for production monitoring. ExplanationCorrect Answer D:Use SNMPv3 authPriv and least-privilege source scoping for production monitoring. This addresses the recurring cause: SNMPv2c community strings provide weak shared-secret style access and lack SNMPv3 auth/privacy protections.

Question 565 SNMPv3 polling with `authPriv` fails after a credential rotation because the monitoring server's privacy password does not match the router user. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Synchronize the SNMPv3 user's authentication and privacy credentials and selected algorithms. Bind the SNMPv3 user to an appropriately restricted read view and avoid write access. Replace broad community access with restricted SNMPv3 credentials and management-source controls where supported. Align the sender's notification user, security level and receiver's accepted identity.
