Question 380
At the Marshport regional library system, workstations see unnecessary high bandwidth video packets when no one on their access ports has joined the stream. How should the organization sustain the improvement?
Explanation
Correct Answer
The continuing safeguard is to track IGMP group and querier health as media demand grows. It helps avoid the original condition: without valid membership tracking multicast can be flooded to unrelated ports. This result addresses the stated challenge at the Marshport regional library system.
Incorrect Answers
it requires the team to monitor peak queue usage and burst indicators. The offered alternative applies that mechanism: Monitor peak queue usage and burst indicators. The reported facts point to a different controlling condition: without valid membership tracking multicast can be flooded to unrelated ports. The alternative does not directly settle the required recurrence control.
Review port-disable records during incident handoff. Its technical scope is explained by: an administratively disabled switch interface cannot forward packets regardless of cable health. In this question, the decisive issue is: without valid membership tracking multicast can be flooded to unrelated ports. That is why the offered option is not the most direct recurrence control.
Review spanning tree root placement and topology change logs. This option is based on the following distinct technical behavior: spanning tree intentionally blocks some redundant Layer 2 paths to avoid loops. The present question instead depends on this mechanism: without valid membership tracking multicast can be flooded to unrelated ports. That difference matters for the requested recurrence control.
