HP Exam HPE7-A02 Topic 12 Question 11 Discussion
Topic #: 12
An AOS-CX switch has been configured to implement UBT to two HPE Aruba Networking gateways that implement VRRP on the users' VLAN. What correctly describes how the switch tunnels UBT users' traffic to those gateways?
User-Based Tunneling (UBT) with VRRP:
UBT allows traffic from authenticated users to be tunneled to an HPE Aruba Networking gateway.
In the case of VRRP, where two gateways are configured for redundancy, the AOS-CX switch will always send the traffic to the primary gateway defined in the UBT zone configuration.
The VRRP state (master/backup) does not impact the UBT decision; the UBT primary configuration takes precedence.
Option Analysis:
Option A: Incorrect. UBT does not strictly follow the VRRP master; it adheres to the UBT primary gateway configuration.
Option B: Correct. The switch tunnels all traffic to the primary gateway configured in the UBT zone.
Option C: Incorrect. UBT does not load-share traffic between gateways.
Option D: Incorrect. UBT uses the primary gateway configured in the UBT zone, not dynamically determined active devices.
