   What is a primary advantage of RSTP over classic STP?

   • ARSTP supports more VLANs than STP
   • BRSTP provides faster convergence on topology changes
   • CRSTP eliminates the need for a root bridge
   • DRSTP uses a shorter BPDU format

   A network engineer is configuring RSTP on a pair of Juniper EX4600 switches that are connected via two links. The engineer wants to use link aggregation (LAG) to provide redundancy and increase bandwidth. The engineer has configured the LAG interface `ae0` and assigned both physical interfaces to it. However, the engineer is unsure whether RSTP will operate correctly on the LAG interface. What should the engineer do to ensure RSTP works correctly with the LAG?

   • AConfigure RSTP on the ae0 interface instead of the individual physical interfaces.
   • BConfigure RSTP on each physical interface individually, and disable RSTP on the ae0 interface.
   • CEnable RSTP on the ae0 interface and also on the physical interfaces for redundancy.
   • DRSTP is not supported on LAG interfaces, so the engineer must use a different protocol.

   A service provider operates a large campus network with multiple VLANs. The network team wants to use MSTP to reduce the number of spanning-tree instances while providing load balancing across redundant links. They have decided to map VLANs 10, 20, and 30 to instance 1, and VLANs 40, 50, and 60 to instance 2. The network has two core switches, CORE-1 and CORE-2, and several access switches. What additional configuration is required on all switches to ensure that the VLAN-to-instance mapping is consistent across the network?

   • AConfigure the same MSTP region name and revision number on all switches.
   • BEnable RSTP on all interfaces that connect to other switches.
   • CAssign a unique MSTP instance ID to each VLAN on every switch.
   • DConfigure the same bridge priority for the root bridge in each MST instance.
