Question 190
A junior engineer needs to see interface counters without editing the device. What command class fits?
- Role-limited administrator access
- Global configuration mode
- Privileged operational show commands
- Interface-specific context
Explanation
Correct Answer
C:Operational show output is diagnostic and nonmutating. Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis.
Incorrect Answers
A:Operators should use least-privilege accounts for approved tasks. But this does not address the case requirement to inspect switch state without configuration changes.
B:Global configuration context is used to change device-wide settings with appropriate authority. But this does not address the case requirement to inspect switch state without configuration changes.
D:Per-port settings must be reviewed and applied within the intended interface scope. But this does not address the case requirement to inspect switch state without configuration changes.

C:Operators should use least-privilege accounts for approved tasks. But this does not address the case requirement to change the correct physical interface.
D:The persistent configuration should be committed or saved according to supported AOS-CX workflow. But this does not address the case requirement to change the correct physical interface.
Question 193
A fix works until an unexpected reboot restores old startup settings. What process was omitted?
- Configuration comparison and checkpoints
- Save persistent running configuration
- Role-limited administrator access
- Privileged operational show commands
Explanation
Correct Answer
B:Persisting the approved configuration protects it across restart. The persistent configuration should be committed or saved according to supported AOS-CX workflow.
Incorrect Answers
A:Comparing changes with known-good state limits mistakes and supports rollback. But this does not address the case requirement to save the intended running state durably.
C:Operators should use least-privilege accounts for approved tasks. But this does not address the case requirement to save the intended running state durably.
D:Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis. But this does not address the case requirement to save the intended running state durably.
Question 194
A switch change caused an outage and the team cannot tell which lines changed. What practice would help?
- Global configuration mode
- Configuration comparison and checkpoints
- Role-limited administrator access
- Interface-specific context
Explanation
Correct Answer
B:Configuration differences and checkpoints enable controlled recovery. Comparing changes with known-good state limits mistakes and supports rollback.
Incorrect Answers
A:Global configuration context is used to change device-wide settings with appropriate authority. But this does not address the case requirement to compare new settings with a known-good version.
C:Operators should use least-privilege accounts for approved tasks. But this does not address the case requirement to compare new settings with a known-good version.
D:Per-port settings must be reviewed and applied within the intended interface scope. But this does not address the case requirement to compare new settings with a known-good version.
Question 195
Contractors currently log in as full administrators to read counters. What control is more appropriate?
- Role-limited administrator access
- Save persistent running configuration
- Configuration comparison and checkpoints
- Privileged operational show commands
Explanation
Correct Answer
A:Role-limited credentials restrict unnecessary configuration power. Operators should use least-privilege accounts for approved tasks.
Incorrect Answers
B:The persistent configuration should be committed or saved according to supported AOS-CX workflow. But this does not address the case requirement to provide operational visibility with minimal privileges.
C:Comparing changes with known-good state limits mistakes and supports rollback. But this does not address the case requirement to provide operational visibility with minimal privileges.
D:Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis. But this does not address the case requirement to provide operational visibility with minimal privileges.
Question 196
A routing neighbor is down and the operator needs to see the OSPF state first. Which interaction should be performed?
- Save persistent running configuration
- Configuration comparison and checkpoints
- Privileged operational show commands
- Global configuration mode
Explanation
Correct Answer
C:Inspect operational status before attempting blind changes. Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis.
Incorrect Answers
A:The persistent configuration should be committed or saved according to supported AOS-CX workflow. But this does not address the case requirement to observe current device state using show commands.
B:Comparing changes with known-good state limits mistakes and supports rollback. But this does not address the case requirement to observe current device state using show commands.
D:Global configuration context is used to change device-wide settings with appropriate authority. But this does not address the case requirement to observe current device state using show commands.
Question 197
A port-security change was added under the wrong interface. What should be inspected?
- Privileged operational show commands
- Interface-specific context
- Save persistent running configuration
- Configuration comparison and checkpoints
Explanation
Correct Answer
B:Interface configuration context links policy to the exact port. Per-port settings must be reviewed and applied within the intended interface scope.
Incorrect Answers
A:Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis. But this does not address the case requirement to correct configuration scope.
C:The persistent configuration should be committed or saved according to supported AOS-CX workflow. But this does not address the case requirement to correct configuration scope.
D:Comparing changes with known-good state limits mistakes and supports rollback. But this does not address the case requirement to correct configuration scope.
Question 198
After successful testing a change is present only in runtime state. What should happen before release closes?
- Interface-specific context
- Privileged operational show commands
- Configuration comparison and checkpoints
- Save persistent running configuration
Explanation
Correct Answer
D:Save or commit the approved configuration as supported. The persistent configuration should be committed or saved according to supported AOS-CX workflow.

B:Show commands reveal actual interfaces, VLANs, neighbors and system information for diagnosis. But this does not address the case requirement to retain settings across a restart.
C:Comparing changes with known-good state limits mistakes and supports rollback. But this does not address the case requirement to retain settings across a restart.
Question 199
Switch management must not be routable from ordinary user subnets. Which network construct can isolate it?
- Management VRF isolation
- AAA administrative authorization
- HTTPS REST service exposure
- Time synchronization via NTP
Explanation
Correct Answer
A:A management VRF separates a management routing table. A separate VRF can keep management traffic apart from the ordinary production data-plane routes.
Incorrect Answers
B:Operator privileges and authentication servers control who can manage the switch. But this does not address the case requirement to partition administrative traffic from user routes.
C:REST management access depends on an enabled service and appropriate VRF/reachability/security controls. But this does not address the case requirement to partition administrative traffic from user routes.
D:Consistent clocks make distributed logs, certificates and event correlation reliable. But this does not address the case requirement to partition administrative traffic from user routes.
Question 200
An API client cannot reach an AOS-CX REST endpoint even though ordinary ping succeeds. What service setup should be checked?
- SSH administrative access
- HTTPS REST service exposure
- DNS resolver configuration
- AAA administrative authorization
Explanation
Correct Answer
B:HTTPS/REST server configuration and VRF exposure control the API. REST management access depends on an enabled service and appropriate VRF/reachability/security controls.
Incorrect Answers
A:Secure shell supports encrypted remote CLI sessions subject to management ACLs and identity. But this does not address the case requirement to allow authorized structured management over the intended VRF.
C:Management agents that use hostnames require correct resolver configuration. But this does not address the case requirement to allow authorized structured management over the intended VRF.
D:Operator privileges and authentication servers control who can manage the switch. But this does not address the case requirement to allow authorized structured management over the intended VRF.
