Just make sure to check the grub config after the update!

I recall that we need to check the boot order after installation, but I’m not clear on how to verify that the original kernel is still available.

I’m a bit confused about the steps for making the updated kernel the default. Is it just changing the `default=` line in grub.conf?

I practiced a similar question where we had to ensure the original kernel was still bootable. I think it involved editing the grub configuration file.

I think I remember needing to use `rpm -ivh` for the kernel installation, but I’m not entirely sure about the exact flags.

I'm pretty sure it uses machine learning to classify the new application, so I'll go with option B.

Hmm, I'm not totally sure about this one. I know IPS systems monitor network traffic, but I'm not positive if they actively stop attacks. Let me think this through a bit more.

I'm kind of torn between `rm -rf` and maybe `reboot`, but I think the first one is definitely more likely to need a backup restore.
