A customer investigating the Aruba SD-Branch solution asks about how the solution will improve WAN performance. What is one answer you should give?

Question

Options

• AAruba User Experience Insight (UXI) sensors continuously monitor the WAN and suggest settings
• BAruba ClearPass Integrates Aruba branch gateways with best-in-industry, third-party WAN
• CAruba CX switches provide the WAN uplinks and offer optimized, fast-converging routing
• DAruba gateways support WAN compression to help the customer get more out the WAN

• B

• C
  9% (2)
• D
  83% (19)

Explanation

Option D is correct because Aruba branch gateways include WAN compression as a built-in capability, reducing the volume of data that must traverse the WAN link. This means customers can effectively squeeze more throughput from their existing WAN circuits without upgrading bandwidth - a direct, tangible WAN performance improvement that is central to the SD-Branch value proposition.

Why the distractors are wrong:

• A - UXI sensors are passive experience-monitoring probes that measure Wi-Fi and application health from the end-user perspective; they observe WAN conditions but do not optimize or improve them.
• B - ClearPass is a network access control (NAC) and policy platform focused on authentication and authorization, not WAN optimization or integration with third-party WAN services.
• C - Aruba CX switches are campus/access-layer switches; WAN uplinks and WAN-facing routing in SD-Branch are handled by the branch gateways, not CX switches.

Memory tip: Anchor on the word "gateway" - in Aruba SD-Branch, the gateway is the device that faces the WAN, so any WAN performance feature (compression, optimization, QoS) lives there. When a distractor names a different Aruba product (UXI, ClearPass, CX), ask yourself "does that product touch the WAN?" - if not, it can't improve WAN performance.
