Wait, can you really remove memory from a powered on VM? Sounds risky!

C is correct, you definitely need to power off for that.

I believe you can add CPU while the VM is running, but I’m not confident about the memory changes. I should have reviewed that section more!

I'm a bit confused about whether you can remove memory from a powered-on VM. I thought it depended on the OS, but I can't recall the details.

I feel like I practiced a question similar to this, and it mentioned that you definitely need to power off the VM to reduce memory.

I think I remember that you can add CPU to a powered-on VM if the guest OS supports it, but I'm not entirely sure about the specifics.

Hmm, I'm a little unsure about the difference between activity, output, and outcome measures. I'll need to review my notes to refresh my memory on those concepts.

Based on the question, I would go with option C and use the GetExaWatcherResults.sh script. It seems like it's designed to pull data from the Exadata environment, which should help identify the network issue.

Hmm, this seems like a question about information processing systems. I'll need to think carefully about the different options and what they might represent.
