HPE Aruba Certified Mobility Expert (ACMX) — Question 28

An Administrator supports a group of employees that connect to the corporate office using the VIA client. An Aruba Mobility Controller (MC), behind a corporate firewall, terminates the users VPN sessions. The VPN sessions fail to establish because of the existing firewall rules.
Which connections must the administrator allow on the firewall? (Choose three.)

Answer options

• A. UDP 8202
• B. UDP 4500
• C. UDP 8211
• D. TCP 4443
• E. TCP 443

Correct answer: A, B, E

Explanation

The correct answer includes UDP 8202, UDP 4500, and TCP 443, which are necessary for establishing and maintaining VPN connections through the firewall. UDP 8202 is used for the control channel, UDP 4500 is for NAT traversal, and TCP 443 is commonly used for secure connections. The other options, UDP 8211 and TCP 4443, are not required for this specific VPN setup.
