Designing Cisco Network Service Architectures (ARCH, legacy) — Question 69

When designing a Data Center Interconnect solution, which two statements describe benefits of utilizing A-VPLS for Layer 2 extension? (Choose two.)

Answer options

• A. Redundancy is addressed without enabling Spanning Tree Protocol in the core.
• B. The overlay of the Layer 2 connection on the Layer 3 transport hides any physical convergence.
• C. Integrated Layer 3 technology responds upon failure.
• D. A-VPLS utilizes the Cisco Catalyst 6500 Series VSS feature to provide native dual-homing.
• E. A-VPLS provides flow-based load balancing over equal-cost multipath paths.

Correct answer: D, E

Explanation

The correct answers are D and E because A-VPLS indeed employs the Cisco Catalyst 6500 Series VSS feature to allow for native dual-homing, enhancing redundancy. Additionally, it provides flow-based load balancing over equal-cost multipath paths, optimizing traffic distribution. Options A, B, and C do not specifically highlight the unique advantages of A-VPLS for Layer 2 extension.
