NEW QUESTION # 80
A Solutions Architect is designing a highly available core layer for a campus network using two HPE Aruba Networking CX 8325 switches. The primary goals are to provide a single, unified management point, eliminate Spanning Tree Protocol (STP) for core links, and ensure seamless failover for downstream access layer switches and connected devices. The architect has chosen to implement Virtual Switching Framework (VSF) to stack the two core switches. What is the primary benefit of using VSF in this design compared to traditional redundancy protocols like STP?
- A. It provides faster convergence than STP by using Layer 3 OSPF for loop prevention.
- B. It allows both switches in the stack to actively forward traffic simultaneously, effectively doubling the core bandwidth.
- C. It increases the number of available physical ports by combining the ports of both switches.
- D. It simplifies IP address management by assigning a separate IP address to each switch in the stack.
Answer: B
