Question
When designing a Data Center Interconnect solution, which two statements describe benefits of utilizing A-VPLS for Layer 2 extension? (Choose two.)
Options
- ARedundancy is addressed without enabling Spanning Tree Protocol in the core
- BThe overlay of the Layer 2 connection on the Layer 3 transport hides any physical convergence.
- CIntegrated Layer 3 technology responds upon failure
- DA-VPLS utlzes the Cisco Catalyst 6500 Series VSS feature to provide native dual-homing.
- EA-VPLS provides flow-based load balancing over equal-cost multipath paths.

Explanation
interconnect/design_guide_c07-647422.html The Cisco ® Layer 2 VPN (L2VPN) Advanced VPLS (A-VPLS) feature introduces the following enhancements to VPLS: • Capability to load-balance traffic across multiple core interfaces using equal-cost multipathing Simplified Redundancy A-VPLS is supported by the Cisco Catalyst ® 6500 and Catalyst 6800 Series Virtual Switching A-VPLS benefits from the multihoming features of VSS and does not require Spanning Tree Protocol for loop prevention. A-VPLS needs to be configured only once
