Which type value on the spanning-tree mode type global command enables the use of RSTP?
- rapid-pvst
- pvst
- rstp
- rpvst
Explanation: Of the four answers, only pvst and rapid-pvst are valid options on the command. Of those, the rapid-pvst option enables Rapid Per VLAN Spanning Tree (RPVST+), which uses RSTP. The pvst option enables Per VLAN Spanning Tree (PVST) which uses STP, not RSTP. The other two options, if attempted, would cause the command to be rejected because the option does not exist.
