Question 10
At the Ashbourne manufacturing plant, a campus building needs resilient aggregation of several access closets but selects a device with insufficient port speeds. Which explanation best accounts for the concern?
Explanation
Correct Answer
This identifies the root issue: undersized aggregation links can oversubscribe building traffic and weaken resiliency. At the Ashbourne manufacturing plant, the team should therefore select an appropriate CX 6300 class deployment using tested uplink capacity and redundancy needs.
Incorrect Answers
The option states: Access device selection does not establish the capacity and latency suitability of aggregation links. By contrast, the current situation is governed by: undersized aggregation links can oversubscribe building traffic and weaken resiliency. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.
Uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The present question instead depends on this mechanism: undersized aggregation links can oversubscribe building traffic and weaken resiliency. That difference matters for the requested root-cause explanation.
The offered alternative states: Multicast delivery and control depend on membership learning and appropriate Layer 3 design. The reported facts point to a different controlling condition: undersized aggregation links can oversubscribe building traffic and weaken resiliency. The alternative does not directly settle the required root-cause explanation.
