A network architect has planned redundant links as shown in the exhibit. What should the network
architect do to ensure that the redundant link design is truly resilient?

A.
Implement the features such as link aggregation, backplane stacking, and intelligent Resilient
Framework (IRF)

B.
Add another link between the Layer 2 switches and the core so that up to the two links can fail

C.
Implement a feature such as bidirectional forwarding detection (BFO) on each redundant link

D.
Make sure that each HP 10508 switch is configured as a root in one Multiple Spanning Tree
Protocol (MSTP) instance
