Surprised that name resolution is still an issue after the access list was applied!

Wait, why would you add a permit for UDP? Isn't that risky?

I feel like I should inspect the traffic, but I can't recall if it should be done globally or just on the interface.

I think option B sounds right because it mentions UDP and the domain, but I’m a bit confused about the logging part.

This question feels similar to one we practiced where we had to modify access lists for DNS. I think adding a permit statement is key here.

I remember something about allowing DNS traffic specifically, but I'm not sure if it's UDP or TCP for IPv6.

Hmm, I'm not sure about this one. The options seem a bit similar, and I'm not entirely clear on the difference between MTTR and MTRS. I'll need to review those concepts before making a decision.

Hmm, I'm a bit unsure about this one. I'll need to think it through carefully. Maybe I should review my notes on BPMN subprocesses again.
