CCIE/CCNP 350-401 ENCOR Dumps Full Questions with VCE & PDF 133

  • A. DSW2 operates in Rapid PVST+ and the new switch operates in PVST+
  • B. Both switches operate in the PVST+ mode
  • C. Spanning tree is disabled automatically on the network
  • D. Both switches operate in the Rapid PVST+ mode.

Explanation: From the output we see DSW2 is running in RSTP mode (in fact Rapid PVST+ mode as Cisco does not support RSTP alone). When a new switch running PVST+ mode is added to the topology, they keep running the old STP instances as RSTP (in fact Rapid PVST+) is compatible with PVST+.
