Explanation

Configuring link A as a Layer 3 routed link removes it from the Layer 2 topology, reducing the number of potential STP paths and preventing loops. Setting switch D as primary root and switch C as secondary root for VLAN 10 ensures predictable and optimal spanning-tree convergence with Rapid PVST+.
