This seems like a straightforward security question. I'll eliminate the options that are too broad or don't directly address the "default network security posture" aspect. I'm leaning towards Option D as the best answer.
I'm a little confused by the wording of this question. I'll need to re-read it a few times and think about the specific security measures that would be applied by default after a deployment.
Okay, I think I've got it. The key is to focus on what the "default network security posture" does to minimize external threats. Option D sounds like the best answer, as it mentions blocking access to specific services and ports.
I'm a bit unsure about this one. The options all seem similar, but I need to make sure I understand the exact meaning of "default network security posture" and how that relates to minimizing external threats.
Okay, I've used vmstat before, so I think I have a good handle on this. The most important info is probably the memory swapping data, since that can be a key indicator of performance issues.
No problem, I've got this. The /etc/hosts file is pretty straightforward, and I'm confident I can identify the two correct options from these examples.
