Isn't it surprising that the master can be unresponsive in a running cluster?

Agreed, the master authorized network entries make sense here.

Wait, why would you assign a public IP? That seems risky.

Definitely need to check the firewall settings.

I feel like assigning a public IP could expose the instance unnecessarily. I’m leaning towards creating a firewall policy instead.

I think I saw a similar question where we had to set up network access for the master. Maybe it's option D?

I remember something about needing to configure access to the master node, but I'm not sure if it's about firewall rules or something else.

I’m a bit confused about the difference between the firewall policy and the master authorized networks. I guess I need to review that part again.

I'm a bit unsure about this one. I'll need to review the details of the model-driven app and the form configuration to figure out the best approach.

Hmm, I'm not totally sure about this one. The senior responsible owner or programme manager might also have a lot of interaction with governance bodies. I'll have to think this through carefully.
