Refer to the exhibit. When designing an MPLS-based LAN extension between DC-1 and DC-2, what are three advantages of deploying VSS? (Choose three.)

VSS with MEC (Multichassis EtherChannel) supports Layer 2, 3, and 4 flow-based load balancing across both chassis, maximizing bandwidth utilization of the LAN extension link.

VSS provides native stateful failover for both the virtual switch and MEC connections without requiring Cisco IOS EEM scripts or waiting for STP topology recalculation.

VSS achieves sub-second failover because the standby supervisor continuously synchronizes state with the active supervisor, enabling near-instantaneous switchover with no STP reconvergence delay.

VPLS does not require VSS and can be configured independently on MPLS-capable devices; VSS is not a prerequisite for VPLS operation.

Failover depending on EEM scripts and STP convergence describes the behavior of a traditional dual-switch design without VSS, which is the limitation VSS is specifically designed to eliminate.

Limited VLAN-based VPLS traffic hashing is a drawback of non-VSS designs; VSS with MEC improves traffic hashing capabilities, making this a disadvantage to avoid rather than an advantage to claim.
