   How does RSTP reduce convergence time compared to STP?

   • ABy using a shorter forward delay timer
   • BBy eliminating the need for BPDUs
   • CBy using a handshake mechanism and port roles to transition ports quickly
   • DBy using a shorter hello timer

   A service provider is designing a network with 200 VLANs and requires rapid convergence and per-VLAN load balancing. The network team is evaluating MSTP and VSTP. The team is concerned about the scalability of running a separate instance for each VLAN. Which protocol should the team choose to meet the requirements while minimizing the number of instances?

   • ASTP
   • BMSTP
   • CVSTP
   • DRSTP

   In MSTP, what is the purpose of mapping VLANs to multiple spanning tree instances (MSTIs)?

   • ATo reduce the number of spanning tree instances needed while allowing load balancing across VLANs
   • BTo eliminate the need for a root bridge
   • CTo provide faster convergence than RSTP
   • DTo allow each VLAN to have its own independent spanning tree

   A network administrator is managing a network with 200 VLANs and wants to use VSTP to provide per-VLAN spanning tree instances. The administrator is concerned about the scalability of running a separate instance for each VLAN. Which statement accurately describes a limitation of VSTP in this scenario?

   • AVSTP requires all VLANs to be mapped to a single spanning tree instance.
   • BVSTP consumes more CPU and memory resources as the number of VLANs increases.
   • CVSTP is only supported on access switches, not on core switches.
   • DVSTP does not support rapid convergence.

   A network engineer is comparing STP and RSTP for a network that experiences frequent link failures. The engineer wants to minimize the time it takes for the network to recover after a link failure. Which feature of RSTP directly contributes to faster convergence compared to STP?

   • ARSTP uses a longer max age timer.
   • BRSTP uses a shorter hello timer.
   • CRSTP uses a single spanning tree instance for all VLANs.
   • DRSTP uses a proposal-agreement handshake to rapidly transition ports to forwarding.
