Question 70
At the Yorkport airport network, a renovated campus will power 48 cameras and phones from a switch whose PoE budget has not been calculated. Which explanation best accounts for the concern?
Explanation
Correct Answer
The strongest explanation is that a port count alone does not guarantee simultaneous available PoE watts. This accounts for the outcome and supports the action to budget per port PoE requirements and total switch power with reserve for critical endpoints. This result addresses the stated challenge at the Yorkport airport network.
Incorrect Answers
Multicast delivery and control depend on membership learning and appropriate Layer 3 design. The present question instead depends on this mechanism: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. 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 recalculate PoE headroom when cameras or phones are upgraded. The alternative does not directly settle the required root-cause explanation.
Core undersizing can create campus-wide congestion and costly replatforming. In this question, the decisive issue is: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. That is why the offered option is not the most direct root-cause explanation.
