Question 370
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: A copper uplink flaps because a port is hard-set to an incompatible speed while its neighbor autonegotiates. Which result BEST demonstrates that this specific issue was resolved?
Explanation
Correct Answer
Interface flaps cease and link negotiation reports the supported common speed. This is the relevant acceptance observation for the reported issue: A copper uplink flaps because a port is hard-set to an incompatible speed while its neighbor autonegotiates. The intended corrective choice is: Align supported speed and autonegotiation settings and check copper media. At Pine Valley Telecom, this outcome verifies actual operation under planned fault-domain isolation, rather than only a ticket marked complete.
Incorrect Answers
Encapsulated packets at the intended size traverse the fabric without fragmentation-related loss. Such an observation would verify a separate issue: An overlay tunnel fails to carry otherwise valid tenant traffic when the underlay path has an insufficient MTU. It would follow the distinct action: Check encapsulation overhead and raise supported underlay MTU consistently along the path. Here the reported failure is A copper uplink flaps because a port is hard-set to an incompatible speed while its neighbor autonegotiates. The decisive result for Pine Valley Telecom must instead be: Interface flaps cease and link negotiation reports the supported common speed.
The replacement reports expected stack membership and stable fabric connectivity. Such an observation would verify a separate issue: An access VSF member repeatedly fails to join after replacement because its stack/member configuration is inconsistent. It would follow the distinct action: Verify compatible software, VSF link topology and assigned member identity before reintegration. Here the reported failure is A copper uplink flaps because a port is hard-set to an incompatible speed while its neighbor autonegotiates. The decisive result for Pine Valley Telecom must instead be: Interface flaps cease and link negotiation reports the supported common speed.
The next synchronization retains the approved local value and all mandated baseline settings. Such an observation would verify a separate issue: A Central template overwrites a necessary switch-specific value during the nightly compliance push. It would follow the distinct action: Reconcile the device's approved exception with group-template variables and configuration ownership. Here the reported failure is A copper uplink flaps because a port is hard-set to an incompatible speed while its neighbor autonegotiates. The decisive result for Pine Valley Telecom must instead be: Interface flaps cease and link negotiation reports the supported common speed.
