Question 730
A campus operator needs to diagnose intermittent packet loss without disrupting an active user port. What should the network engineer do to address this requirement?
- Configure supported port mirroring to an authorized packet-capture destination
- Use the supported authenticated REST API with read-only scope for inventory collection
- Use supported configuration audit/events and NAE checkpoints where appropriate
- Verify API credentials, user role, endpoint permissions and supported version
Explanation
Correct Answer
A:Mirroring provides traffic evidence while the production link remains active. An empty capture can indicate incorrect mirroring rather than no traffic.
Incorrect Answers
B:Structured state retrieval can reduce manual transcription errors. It would not resolve the documented symptom; mirroring provides traffic evidence while the production link remains active.
C:Configuration history can link a new symptom to a recent change. In this situation, mirroring provides traffic evidence while the production link remains active.
D:REST access depends on authentication and authorization independent of network ping. By contrast, mirroring provides traffic evidence while the production link remains active.
Question 731
A campus operator needs to diagnose intermittent packet loss without disrupting an active user port. What should the team inspect to confirm the result?
- Compare per-branch application latency and failed service steps with incident reports
- Compare historical values and the exact timestamps of alerts with service performance
- Inspect HTTP status, requested URI and the role assigned to the token/account
- Verify source/destination mirror direction and captured frames during a small test
Explanation
Correct Answer
D:An empty capture can indicate incorrect mirroring rather than no traffic. Mirroring provides traffic evidence while the production link remains active.
Incorrect Answers
A:The monitoring result must map to the problem users experience. It would not resolve the documented symptom; an empty capture can indicate incorrect mirroring rather than no traffic.
B:Actual counter behavior reveals whether the rule is too sensitive. The relevant technical distinction is that an empty capture can indicate incorrect mirroring rather than no traffic.
C:A 403-style denial can differ from missing endpoint or reachability. By contrast, an empty capture can indicate incorrect mirroring rather than no traffic.
Question 732
A campus operator needs to diagnose intermittent packet loss without disrupting an active user port. Which misconception is most likely to obstruct a correct fix?
- Assume enabling syslog automatically records every packet payload on the switch
- Assume a green AP inventory icon guarantees every client application is reachable
- Delete every duplicate-looking alarm without checking whether two physical switches share a hostname
- Rely exclusively on a single point-in-time show command after an intermittent fault stops
Explanation
Correct Answer
A:Event logs do not replace traffic capture. Mirroring provides traffic evidence while the production link remains active.
Incorrect Answers
B:Control connectivity is different from user data service. By contrast, event logs do not replace traffic capture.
C:Names alone do not guarantee device identity. The relevant technical distinction is that event logs do not replace traffic capture.
D:Transient errors may no longer be visible in one snapshot. Here, however, event logs do not replace traffic capture.
Question 733
A campus operator needs to diagnose intermittent packet loss without disrupting an active user port. What precaution is most important before the change is expanded?
- Restrict capture access and retention of sensitive data
- Retain meaningful historical windows and monitor disk/resource limits
- Pilot revised thresholds and document why the alert rule changed
- Define an escalation path combining wired, WLAN and application teams
Explanation
Correct Answer
A:Mirrored frames can contain confidential information. An empty capture can indicate incorrect mirroring rather than no traffic.
Incorrect Answers
B:Monitoring must not consume unreasonable switch resources. Here, however, mirrored frames can contain confidential information.
C:Controlled tuning preserves a trusted monitoring baseline. In this situation, mirrored frames can contain confidential information.
D:Cross-domain ownership avoids slow ticket handoffs. The relevant technical distinction is that mirrored frames can contain confidential information.
Question 734
A monitoring team wants an alert when a specific AOS-CX interface error counter rises unusually fast. Which configuration decision most directly resolves the situation?
- Deploy an appropriate NAE agent with monitored counter and alert threshold
- Use the supported authenticated REST API with read-only scope for inventory collection
- Install a supported UXI sensor with wired/wireless and application tests appropriate to the site
- Deploy UXI tests for selected internal/external apps and align sites with monitoring tags
Explanation
Correct Answer
A:NAE can track local switch telemetry and respond to changes. A configured script must actually create the expected monitored event.
Incorrect Answers
B:Structured state retrieval can reduce manual transcription errors. Here, however, nAE can track local switch telemetry and respond to changes.
C:UXI can simulate end-user service from the physical location. It would not resolve the documented symptom; nAE can track local switch telemetry and respond to changes.
D:Synthetic clients can measure business service from the user's perspective. In this situation, nAE can track local switch telemetry and respond to changes.
Question 735
A monitoring team wants an alert when a specific AOS-CX interface error counter rises unusually fast. Which check most directly demonstrates the desired network behavior?
- Compare historical values and the exact timestamps of alerts with service performance
- Verify source/destination mirror direction and captured frames during a small test
- Compare AP/client logs, switch port changes and UXI results by timestamp
- Increase errors in a safe lab test and inspect the agent's time-series graph and alert
Explanation
Correct Answer
D:A configured script must actually create the expected monitored event. NAE can track local switch telemetry and respond to changes.
Incorrect Answers
A:Actual counter behavior reveals whether the rule is too sensitive. By contrast, a configured script must actually create the expected monitored event.
B:An empty capture can indicate incorrect mirroring rather than no traffic. It would not resolve the documented symptom; a configured script must actually create the expected monitored event.
C:Correlation separates radio loss from wired or application impact. In this situation, a configured script must actually create the expected monitored event.
Question 736
A monitoring team wants an alert when a specific AOS-CX interface error counter rises unusually fast. Which assumption would be most misleading when investigating this situation?
- Assume a green AP inventory icon guarantees every client application is reachable
- Assume an NAE script file produces alerts before an agent is instantiated or enabled
- Assume enabling syslog automatically records every packet payload on the switch
- Count access points alone and use that as the main application reliability metric
Explanation
Correct Answer
B:A script definition is not necessarily a running monitoring instance. NAE can track local switch telemetry and respond to changes.
Incorrect Answers
A:Control connectivity is different from user data service. It would not resolve the documented symptom; a script definition is not necessarily a running monitoring instance.
C:Event logs do not replace traffic capture. By contrast, a script definition is not necessarily a running monitoring instance.
D:Hardware count does not measure end-to-end performance. The relevant technical distinction is that a script definition is not necessarily a running monitoring instance.
Question 737
A monitoring team wants an alert when a specific AOS-CX interface error counter rises unusually fast. Which safeguard best reduces the deployment risk in this case?
- Restrict capture access and retention of sensitive data
- Use bounded thresholds and alert ownership to prevent floods
- Define an escalation path combining wired, WLAN and application teams
- Create a least-privilege service identity with credential rotation
Explanation
Correct Answer
B:Overly chatty monitoring can hide important incidents. A configured script must actually create the expected monitored event.
Incorrect Answers
A:Mirrored frames can contain confidential information. Here, however, overly chatty monitoring can hide important incidents.
C:Cross-domain ownership avoids slow ticket handoffs. By contrast, overly chatty monitoring can hide important incidents.
D:Automated tools should not share a human super-admin account. The relevant technical distinction is that overly chatty monitoring can hide important incidents.
Question 738
A remote operations team wants to know whether a classroom's Wi-Fi experience is degraded even without user complaints. What is the most appropriate first technical change?
- Install a supported UXI sensor with wired/wireless and application tests appropriate to the site
- Deploy UXI tests for selected internal/external apps and align sites with monitoring tags
- Verify API credentials, user role, endpoint permissions and supported version
- Use the supported authenticated REST API with read-only scope for inventory collection
Explanation
Correct Answer
A:UXI can simulate end-user service from the physical location. Service-level tests reveal failures missed by infrastructure-up status.
Incorrect Answers
B:Synthetic clients can measure business service from the user's perspective. The relevant technical distinction is that uXI can simulate end-user service from the physical location.
C:REST access depends on authentication and authorization independent of network ping. In this situation, uXI can simulate end-user service from the physical location.
D:Structured state retrieval can reduce manual transcription errors. Here, however, uXI can simulate end-user service from the physical location.
Question 739
A remote operations team wants to know whether a classroom's Wi-Fi experience is degraded even without user complaints. Which observation would best verify that the intended behavior is working?
- Compare AP/client logs, switch port changes and UXI results by timestamp
- Inspect HTTP status, requested URI and the role assigned to the token/account
- Compare alert sources and unique hardware identifiers for repeated events
- Review DNS, DHCP, WLAN association and application test outcomes from the sensor
Explanation
Correct Answer
D:Service-level tests reveal failures missed by infrastructure-up status. UXI can simulate end-user service from the physical location.
Incorrect Answers
A:Correlation separates radio loss from wired or application impact. It would not resolve the documented symptom; service-level tests reveal failures missed by infrastructure-up status.
B:A 403-style denial can differ from missing endpoint or reachability. In this situation, service-level tests reveal failures missed by infrastructure-up status.
C:Source correlation distinguishes duplication from real second failures. Here, however, service-level tests reveal failures missed by infrastructure-up status.
Question 740
A remote operations team wants to know whether a classroom's Wi-Fi experience is degraded even without user complaints. Which belief about the configuration should the team reject?
- Count access points alone and use that as the main application reliability metric
- Disable all monitoring forever because one NAE agent is noisy
- Use only core switch CPU data as a complete measurement of student Wi-Fi experience
- Assume a green AP inventory icon guarantees every client application is reachable
Explanation
Correct Answer
C:Healthy switches cannot prove every app works at the edge. UXI can simulate end-user service from the physical location.
Incorrect Answers
A:Hardware count does not measure end-to-end performance. It would not resolve the documented symptom; healthy switches cannot prove every app works at the edge.
B:A tuning problem does not justify losing operational visibility. In this situation, healthy switches cannot prove every app works at the edge.
D:Control connectivity is different from user data service. By contrast, healthy switches cannot prove every app works at the edge.
