HPE Aruba Certified Campus Access Professional (ACAP) — Question 12

A company currently has 45 IAP-315 at a remote site. These IAPs connect to the main office on a WAN link and use an IPsec VPN to an MC. The company has determined that it needs better optimization and higher VPN throughput for traffic sent to the main office.
What should the network architect propose to fill this gap?

Answer options

• A. a subscription to Aruba Central services for WAN optimization
• B. the deployment of several additional IAP-315 to boost throughput
• C. the deployment of a local MC at the remote site
• D. the purchase of SD-WAN licenses for the remote site IAPs

Correct answer: D

Explanation

The correct answer, D, is appropriate because SD-WAN licenses enhance VPN performance and provide better traffic management over the WAN. Options A and B do not specifically address the need for higher VPN throughput, and option C, while potentially beneficial, does not directly resolve the optimization issue as effectively as implementing SD-WAN solutions.
