Question 550
A router automation app can read device state but unexpectedly receives permission to change every interface. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. This checks the relevant condition before an engineer modifies production access or detection behavior. Programmable interfaces are management planes with security obligations comparable to CLI access; enabling RESTCONF does not itself validate an automation request. The controlled response would be: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. This supplies the diagnostic evidence needed for the complementary action. Situation: A router automation app can read device state but unexpectedly receives permission to change every interface.
Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. This control addresses the failure mechanism and narrows the enforcement boundary. Programmable interfaces are management planes with security obligations comparable to CLI access; enabling RESTCONF does not itself validate an automation request. Confirm pre-change conditions using: Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. This is the implementation portion of the complementary pair. Situation: A router automation app can read device state but unexpectedly receives permission to change every interface.
Incorrect Answers
Inspect source/destination tuples, flow duration, byte counts, exporters, collector receipt, and sampling configuration. This step could matter for NetFlow and telemetry flow analysis but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A router automation app can read device state but unexpectedly receives permission to change every interface.
Intended users receive the correct policy and connection failures can be attributed to a specific AAA stage. This step could matter for RADIUS network access troubleshooting but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A router automation app can read device state but unexpectedly receives permission to change every interface.
Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views. This step could matter for SNMPv3 authenticated encrypted polling but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A router automation app can read device state but unexpectedly receives permission to change every interface.
