HPE Aruba Certified Professional (ACP) – SD-WAN — Question 67

Your customer has an existing gateway cluster that they are using to tunnel traffic from APs and would like to configure the same for their CX switches. Which tunnelling option should you recommend?

Answer options

• A. UBT
• B. GRE
• C. IPSec
• D. VNBT

Correct answer: A

Explanation

UBT (Unified Bridge Tunneling) is specifically designed for tunneling in environments like this, making it the ideal recommendation for the customer's needs. GRE, IPSec, and VNBT do not provide the same level of integration with the existing setup and may not support the specific requirements for CX switches as effectively as UBT does.
