Question 570
At Pine Valley Telecom, the provider infrastructure team is preparing a regional hub modernization. The operational constraint is planned fault-domain isolation. A production-readiness reviewer asks for proof addressing: Switch memory utilization climbs after a firmware update and the team ignores software health statistics. Which result BEST demonstrates that this specific issue was resolved?
Explanation
Correct Answer
Memory use stabilizes after verified remediation and no longer threatens availability. This is the relevant acceptance observation for the reported issue: Switch memory utilization climbs after a firmware update and the team ignores software health statistics. The intended corrective choice is: Compare memory, process and software-version telemetry with the prechange baseline and known defect guidance. At Pine Valley Telecom, this outcome verifies actual operation under planned fault-domain isolation, rather than only a ticket marked complete.
Incorrect Answers
The identified environmental or link problem is addressed and timed flap alarms cease. Such an observation would verify a separate issue: Logs repeatedly report interface flap events at the same hour when janitorial equipment is powered. It would follow the distinct action: Correlate timestamped switch syslog, power events and physical link counters before concluding the root cause. Here the reported failure is Switch memory utilization climbs after a firmware update and the team ignores software health statistics. The decisive result for Pine Valley Telecom must instead be: Memory use stabilizes after verified remediation and no longer threatens availability.
The peer reaches Established and route exchange follows intended filters. Such an observation would verify a separate issue: A BGP session moves between Idle and Active and receives no routes. It would follow the distinct action: Inspect transport reachability, peer IP, ASNs, TCP/179 policy and authentication conditions. Here the reported failure is Switch memory utilization climbs after a firmware update and the team ignores software health statistics. The decisive result for Pine Valley Telecom must instead be: Memory use stabilizes after verified remediation and no longer threatens availability.
All intended members report synchronized forwarding and aggregate utilization follows expected paths. Such an observation would verify a separate issue: An LACP group has four configured members but only two report collecting and distributing. It would follow the distinct action: Inspect LACP partner state, compatible keys and bundle parameters for the inactive members. Here the reported failure is Switch memory utilization climbs after a firmware update and the team ignores software health statistics. The decisive result for Pine Valley Telecom must instead be: Memory use stabilizes after verified remediation and no longer threatens availability.
