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.

Wait, does it really always go to the master? Sounds odd.

Definitely not load sharing, that's for sure!

I agree, it's all about the primary gateway in the UBT zone.

I think it's actually the active device gateway.

The switch sends traffic to the VRRP master.

I feel like load sharing is not how UBT typically operates with VRRP, so I would probably rule out option C.

I'm a bit confused about whether the switch always sends traffic to the primary gateway or the active device. I should have reviewed that part more.

I remember practicing a question similar to this, and I think it was about how UBT zones work with gateways. I might lean towards option D.

I think the switch sends traffic to the VRRP master, but I'm not completely sure. It feels like I studied that concept a lot.

I'm a bit confused by this question. The wording is a bit complex, and I'm not entirely familiar with the UBT and VRRP concepts. I'll need to review my notes and try to piece together how the switch would handle this scenario.

Okay, I think I've got this. The key is understanding how the switch interacts with the VRRP gateways. Based on the information provided, I believe the switch would load-share the users' traffic across both gateways, so I'll go with option C.

Hmm, this is a tricky one. I'm not entirely sure how the switch would handle the UBT traffic in this setup with VRRP. I'll need to think through the different possibilities and see if I can eliminate any of the answer choices.

This question seems to be testing my understanding of how the AOS-CX switch handles UBT traffic when there are VRRP gateways involved. I'll need to carefully consider the different options and how the switch would behave in that scenario.

Option A is the way to go, my friends. After all, the VRRP master is the one who's calling the shots, right? Gotta keep that traffic flowing!

I think option D is the way to go. The switch should send the traffic to the gateway assigned as the active device, which makes the most sense for the VRRP configuration.

Yes, sending all users' traffic to the gateway assigned as the active device makes sense in this scenario.
