Question 50
At the Harborwick regional library system, an enterprise wants single-switch failure tolerance but its access layer has only one upstream device. What risk should the team identify as the primary issue?
Explanation
Correct Answer
The architectural weakness is that a single upstream path contradicts the stated campus availability objective. It can be addressed through the controlled change to plan supported redundant uplinks with the appropriate loop prevention or multi-chassis technology. This result addresses the stated challenge at the Harborwick regional library system.
Incorrect Answers
The option states: Cloud management discovery and authentication can fail without basic underlay services. By contrast, the current situation is governed by: it requires the team to retest topology after link and switch replacements. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.
Undersized aggregation links can oversubscribe building traffic and weaken resiliency. The present question instead depends on this mechanism: it requires the team to retest topology after link and switch replacements. That difference matters for the requested root-cause explanation.
data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product. The reported facts point to a different controlling condition: it requires the team to retest topology after link and switch replacements. The alternative does not directly settle the required root-cause explanation.
