Refer to the exhibit. An engineer must provide a redesign for the distribution and access layers of the network. Which correction allows for a more efficient design?
The correct answer is B. Reconfigure the Distribution Switch A to become the HSRP Active. In a typical campus distribution/access design, the HSRP active router should align with the Spanning Tree Protocol (STP) root to avoid suboptimal traffic paths. If Distribution Switch A is the STP root but Distribution Switch B is the HSRP active gateway, traffic from access…

Explanation
In a typical campus distribution/access design, the HSRP active router should align with the Spanning Tree Protocol (STP) root to avoid suboptimal traffic paths. If Distribution Switch A is the STP root but Distribution Switch B is the HSRP active gateway, traffic from access switches follows STP to Distribution Switch A, then must cross the distribution interconnect link to reach Distribution Switch B (the HSRP gateway) - an inefficient and asymmetric path. Making Distribution Switch A the HSRP active (B) aligns HSRP with STP, ensuring traffic takes the shortest path. An EtherChannel (C) adds bandwidth but does not fix the topology asymmetry. A routed link (A) between distribution switches does not resolve the HSRP/STP misalignment.
