QuestionQ38

Analyze requirements

You are selecting switches for a new rack that must support several traffic types, including HTTPS multicast streaming and iSCSI traffic. You are deciding between the CX 8360v2-32Y6C and CX 8325-48Y8C models, both of which satisfy the rack’s port requirements.

Which technical requirement should lead you toward the 8325 model?

  • A A requirement to route the multicast traffic across multiple subnets
  • B A requirement to support a mix of 10GbE and 25GbE server connections
  • C A requirement to allocate two different specific amounts of buffer space to platinum-tier and to gold-tier iSCSI storage
  • D A requirement to support both IP ECN AND PFC
Explanation

The Aruba CX 8325 has three configurable lossless QoS buffer pools, allowing distinct buffer allocations for separate iSCSI service tiers. The CX 8360 has a single fixed lossless QoS pool that is not exposed for configuration, so it cannot provide independently sized platinum-tier and gold-tier lossless buffer allocations.
