I thought we had more than 5 nodes ready, that's surprising!

Nice, but what if some nodes are still in the process of starting up?

Wait, are we sure those taints are being applied correctly?

I feel like we should write the output to the file using redirection, but I'm a bit confused about the syntax for that part.

If I remember correctly, we might need to use `--field-selector` to exclude the NoSchedule taint, but I need to double-check that.

I remember practicing a similar question where we had to count nodes, but I can't recall the exact command for excluding tainted ones.

I think we need to use `kubectl get nodes` to check the status, but I'm not sure how to filter out the tainted nodes.

This question is a bit tricky. I'm not sure if I should use the table buffer or just reference the table directly in the SQL statement. I'll need to think this through carefully before selecting an answer.

I'm pretty sure the correct option is D. hovtest. That's the SAS procedure used to test for homogeneity of variance.

Hmm, I'm a bit unsure about this one. I know IKE has something to do with establishing a secure connection, but I'm not sure about the specific functions. I'll have to think this through carefully.
