Which CX switch model supports ERPS/VSX DCI?

Full set: 98 questions
Answer options
A: 5130
B: 8100
C: 8325 Correct answer
D: 2930F
Correct Answer:
C. 8325
Explanation

The Aruba 8325 Switch Series is a high-performance data center and core switch platform running the ArubaOS-CX network operating system. It is specifically designed to support advanced resiliency and Data Center Interconnect (DCI) features. The combination of Virtual Switching Extension (VSX) for device-level redundancy and Ethernet Ring Protection Switching (ERPS) for Layer 2 loop prevention is a validated DCI solution on the 8325 platform. This architecture provides a highly available, loop-free, and resilient network fabric suitable for interconnecting data centers.

Why Incorrect

A. 5130: This switch runs the Comware operating system, not ArubaOS-CX, and therefore does not support the VSX feature required for this solution.
B. 8100: While the 8100 is an ArubaOS-CX switch that supports VSX, it is positioned for campus aggregation and is not the platform validated for the advanced ERPS/VSX DCI solution.
D. 2930F: This switch runs the ArubaOS-Switch operating system, which uses Virtual Switching Framework (VSF) for stacking, not the VSX high-availability technology.

"Supported platforms": This guide lists the switch series that support VSX

which includes the 8325. It confirms that models like the 2930F and 5130

which do not run ArubaOS-CX

are not on the list.
