   What is the primary purpose of the original Spanning Tree Protocol (802.1D) in a switched network?

   • ATo increase the speed of frame forwarding by using all available links
   • BTo provide redundancy by allowing multiple active paths between switches
   • CTo provide load balancing across multiple equal-cost paths
   • DTo prevent Layer 2 loops by creating a loop-free logical topology

   A service provider operates a large campus network with multiple VLANs. The network team wants to reduce the number of spanning tree instances while still providing per-VLAN load balancing across two distribution switches. They decide to use MSTP. Which configuration step is essential to ensure that switches in the same MST region agree on the VLAN-to-instance mapping?

   • AEnable RSTP on all switches to ensure rapid convergence.
   • BConfigure the same MST region name and revision number on all switches in the region.
   • CConfigure a different MST region name on each switch to avoid conflicts.
   • DAssign each VLAN to a different MST instance on each switch.

   What is the role of the Internal Spanning Tree (IST) in an MSTP region?

   • AIt is a mechanism to map VLANs to multiple spanning tree instances
   • BIt is a separate spanning tree instance for each VLAN in the region
   • CIt is the spanning tree instance that carries BPDUs and connects the region to other regions
   • DIt is a protocol used to elect the regional root bridge

   A network administrator is configuring MSTP across multiple sites. The administrator wants to ensure that switches in different sites can be part of the same MST region. What must be true for this to happen?

   • AAll switches must use the same bridge priority.
   • BAll switches must be connected directly to each other.
   • CAll switches must be in the same Layer 2 broadcast domain.
   • DAll switches must have the same region name, revision number, and VLAN-to-instance mapping.
