No traffic on traffic-group-1 seems like a big factor.

I think it's definitely the racoon service issue.

I feel like the lack of traffic on traffic-group-1 could be a reason for the failover, but I need to double-check if that’s a common trigger we discussed.

I’m a bit confused about the racoon service. I know it’s related to VPNs, but I’m not sure if its stopping is the main cause of the failover here.

I think the log mentions the peer group score, which might indicate that the peer device left the traffic group. That sounds familiar from our practice questions.

I remember something about HA group scores affecting failover, but I'm not entirely sure how that works in this context.

This one looks tricky, but I think I can figure it out. The key is to remember the PIM DR election process and how the different priorities and IP addresses factor in.

Hmm, I'm a bit unsure about the differences between some of these options. I'll need to re-read the question and the options carefully to make sure I select the right three.

This seems like a straightforward question about exchange rate risks. I'll think through the different types and see which one best fits the scenario.
