A network architect is proposing this solution to a customer. The customer network manager has a
preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast
convergence when a link fails and also provides per-VLAN load-sharing over links.
How would the network architect explain why the solution fits these requirements?

A.
The MSTP component of the solution fulfills the same needs as PVST+ MSTP simply balances
traffic per instance rather than per-VLAN

B.
The redundant links between the switches are protected by MSTP and the built-in loop guard
on HP-3800 switches. MSTP provides load-sharing and loop guard provides resiliency

C.
The solution as shown provides the same load-sharing benefits as PVST+. To achieve the
same resiliency benefits, the architect can add smart link to the meshed stack

D.
The link aggregation between tiers provide even better resiliency and load-sharing than PVST+
while MSTP protects against accidental loops
