Question 770
A campus team wants to detect unexpected configuration changes on access switches. Which configuration decision most directly resolves the situation?
- Configure supported port mirroring to an authorized packet-capture destination
- Use supported configuration audit/events and NAE checkpoints where appropriate
- Deduplicate devices by authoritative serial and management identity
- Verify API credentials, user role, endpoint permissions and supported version
Explanation
Correct Answer
B:Configuration history can link a new symptom to a recent change. A diff establishes the actual altered setting.
Incorrect Answers
A:Mirroring provides traffic evidence while the production link remains active. In this situation, configuration history can link a new symptom to a recent change.
C:One physical switch should not appear as independent incidents in two systems. By contrast, configuration history can link a new symptom to a recent change.
D:REST access depends on authentication and authorization independent of network ping. It would not resolve the documented symptom; configuration history can link a new symptom to a recent change.
Question 771
A campus team wants to detect unexpected configuration changes on access switches. Which check most directly demonstrates the desired network behavior?
- Check a UXI or test-client workflow from association through app response
- Verify source/destination mirror direction and captured frames during a small test
- Inspect HTTP status, requested URI and the role assigned to the token/account
- Compare a documented baseline with the device's changed interfaces and associated timestamps
Explanation
Correct Answer
D:A diff establishes the actual altered setting. Configuration history can link a new symptom to a recent change.
Incorrect Answers
A:End-to-end measurement locates the failure beyond AP status. By contrast, a diff establishes the actual altered setting.
B:An empty capture can indicate incorrect mirroring rather than no traffic. The relevant technical distinction is that a diff establishes the actual altered setting.
C:A 403-style denial can differ from missing endpoint or reachability. It would not resolve the documented symptom; a diff establishes the actual altered setting.
Question 772
A campus team wants to detect unexpected configuration changes on access switches. Which assumption would be most misleading when investigating this situation?
- Grant unrestricted administrator rights to the automation account immediately
- Disable all monitoring forever because one NAE agent is noisy
- Assume a green AP inventory icon guarantees every client application is reachable
- Assume every user complaint must originate from an ISP event rather than a local change
Explanation
Correct Answer
D:Local configuration changes frequently explain sudden reachability issues. Configuration history can link a new symptom to a recent change.
Incorrect Answers
A:Broad privileges conceal the correct access model and increase risk. Here, however, local configuration changes frequently explain sudden reachability issues.
B:A tuning problem does not justify losing operational visibility. The relevant technical distinction is that local configuration changes frequently explain sudden reachability issues.
C:Control connectivity is different from user data service. By contrast, local configuration changes frequently explain sudden reachability issues.
Question 773
A campus team wants to detect unexpected configuration changes on access switches. Which TWO actions together implement the required change and verify that it works? Choose TWO.
- Use supported configuration audit/events and NAE checkpoints where appropriate
- Deduplicate devices by authoritative serial and management identity
- Compare a documented baseline with the device's changed interfaces and associated timestamps
- Set service-level thresholds and an owner for each application test
- Configure supported port mirroring to an authorized packet-capture destination
Explanation
Correct Answers
A:Configuration history can link a new symptom to a recent change. A diff establishes the actual altered setting.
C:A diff establishes the actual altered setting. Configuration history can link a new symptom to a recent change.
Incorrect Answers
B:One physical switch should not appear as independent incidents in two systems. The relevant technical distinction is that configuration history can link a new symptom to a recent change.
D:Alerts need actionable definitions and response responsibility. Here, however, governance improves accountability and recovery.
E:Mirroring provides traffic evidence while the production link remains active. In this situation, configuration history can link a new symptom to a recent change.
Question 774
An administrator attempts an API automation but receives HTTP authorization errors from the AOS-CX switch. What is the most appropriate first technical change?
- Configure supported port mirroring to an authorized packet-capture destination
- Verify API credentials, user role, endpoint permissions and supported version
- Verify whether ingress, egress or both directions are mirrored and confirm the analyzer link
- Track error counters over time with supported NAE or monitoring telemetry
Explanation
Correct Answer
B:REST access depends on authentication and authorization independent of network ping. A 403-style denial can differ from missing endpoint or reachability.
Incorrect Answers
A:Mirroring provides traffic evidence while the production link remains active. It would not resolve the documented symptom; rEST access depends on authentication and authorization independent of network ping.
C:Mirror direction settings determine which frames can be observed. In this situation, rEST access depends on authentication and authorization independent of network ping.
D:Time series reveal whether a defect correlates with load or maintenance. Here, however, rEST access depends on authentication and authorization independent of network ping.
Question 775
An administrator attempts an API automation but receives HTTP authorization errors from the AOS-CX switch. Which observation would best verify that the intended behavior is working?
- Inspect HTTP status, requested URI and the role assigned to the token/account
- Correlate session ID, RADIUS response and interface event for a sample login
- Verify source/destination mirror direction and captured frames during a small test
- Compare per-branch application latency and failed service steps with incident reports
Explanation
Correct Answer
A:A 403-style denial can differ from missing endpoint or reachability. REST access depends on authentication and authorization independent of network ping.
Incorrect Answers
B:Matching identifiers separate policy denial from unreachable services. By contrast, a 403-style denial can differ from missing endpoint or reachability.
C:An empty capture can indicate incorrect mirroring rather than no traffic. It would not resolve the documented symptom; a 403-style denial can differ from missing endpoint or reachability.
D:The monitoring result must map to the problem users experience. In this situation, a 403-style denial can differ from missing endpoint or reachability.
Question 776
An administrator attempts an API automation but receives HTTP authorization errors from the AOS-CX switch. Which belief about the configuration should the team reject?
- Grant unrestricted administrator rights to the automation account immediately
- Rely exclusively on a single point-in-time show command after an intermittent fault stops
- Assume enabling syslog automatically records every packet payload on the switch
- Delete every duplicate-looking alarm without checking whether two physical switches share a hostname
Explanation
Correct Answer
A:Broad privileges conceal the correct access model and increase risk. REST access depends on authentication and authorization independent of network ping.
Incorrect Answers
B:Transient errors may no longer be visible in one snapshot. By contrast, broad privileges conceal the correct access model and increase risk.
C:Event logs do not replace traffic capture. The relevant technical distinction is that broad privileges conceal the correct access model and increase risk.
D:Names alone do not guarantee device identity. It would not resolve the documented symptom; broad privileges conceal the correct access model and increase risk.
Question 777
An administrator attempts an API automation but receives HTTP authorization errors from the AOS-CX switch. What should be included in the rollout plan to limit a foreseeable failure?
- Place sensors in representative user areas and review alert thresholds
- Define an escalation path combining wired, WLAN and application teams
- Require reviewed change tickets and alert on out-of-window modifications
- Create a least-privilege service identity with credential rotation
Explanation
Correct Answer
D:Automated tools should not share a human super-admin account. A 403-style denial can differ from missing endpoint or reachability.
Incorrect Answers
A:A sensor in a quiet closet may not reflect classrooms. The relevant technical distinction is that automated tools should not share a human super-admin account.
B:Cross-domain ownership avoids slow ticket handoffs. By contrast, automated tools should not share a human super-admin account.
C:Governance improves accountability and recovery. Here, however, automated tools should not share a human super-admin account.
Question 778
A customer service manager wants a dashboard representing actual Wi-Fi application quality at several branches. What should the network engineer do to address this requirement?
- Correlate AP telemetry with client role, DNS and application reachability measurements
- 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
- Track error counters over time with supported NAE or monitoring telemetry
Explanation
Correct Answer
C:Synthetic clients can measure business service from the user's perspective. The monitoring result must map to the problem users experience.
Incorrect Answers
A:Infrastructure health is one layer of a complete service path. In this situation, synthetic clients can measure business service from the user's perspective.
B:UXI can simulate end-user service from the physical location. The relevant technical distinction is that synthetic clients can measure business service from the user's perspective.
D:Time series reveal whether a defect correlates with load or maintenance. Here, however, synthetic clients can measure business service from the user's perspective.
Question 779
A customer service manager wants a dashboard representing actual Wi-Fi application quality at several branches. What should the team inspect to confirm the result?
- Verify source/destination mirror direction and captured frames during a small test
- Compare per-branch application latency and failed service steps with incident reports
- Inspect HTTP status, requested URI and the role assigned to the token/account
- Increase errors in a safe lab test and inspect the agent's time-series graph and alert
Explanation
Correct Answer
B:The monitoring result must map to the problem users experience. Synthetic clients can measure business service from the user's perspective.
Incorrect Answers
A:An empty capture can indicate incorrect mirroring rather than no traffic. Here, however, the monitoring result must map to the problem users experience.
C:A 403-style denial can differ from missing endpoint or reachability. In this situation, the monitoring result must map to the problem users experience.
D:A configured script must actually create the expected monitored event. It would not resolve the documented symptom; the monitoring result must map to the problem users experience.
Question 780
A customer service manager wants a dashboard representing actual Wi-Fi application quality at several branches. Which misconception is most likely to obstruct a correct fix?
- Use only core switch CPU data as a complete measurement of student Wi-Fi experience
- Assume an NAE script file produces alerts before an agent is instantiated or enabled
- Count access points alone and use that as the main application reliability metric
- Rely exclusively on a single point-in-time show command after an intermittent fault stops
Explanation
Correct Answer
C:Hardware count does not measure end-to-end performance. Synthetic clients can measure business service from the user's perspective.
Incorrect Answers
A:Healthy switches cannot prove every app works at the edge. In this situation, hardware count does not measure end-to-end performance.
B:A script definition is not necessarily a running monitoring instance. By contrast, hardware count does not measure end-to-end performance.
D:Transient errors may no longer be visible in one snapshot. It would not resolve the documented symptom; hardware count does not measure end-to-end performance.
