Agreed, but the steps look solid overall!

I think the tar command should include the `-j` flag for bzip2 directly.

Wait, did you really reboot after checking SELinux? Seems unnecessary.

Yup, bzip2 is the way to go for compression.

Just a reminder, make sure SELinux is set to enforcing!

I recall that we should use `tar cvjf` for creating a bzip2 compressed archive, but I’m not entirely sure if I need to specify the compression option separately.

I’m a bit confused about the order of commands. Should I check SELinux status before or after creating the backup file?

I think we did a similar question where we had to check SELinux status. I just need to remember the command to switch it to enforcing mode if it’s not already.

I remember we practiced creating tar files, but I’m not sure if I need to use the `-j` option for bzip2 compression directly with tar.

I'm a bit confused by this question. There are a few different options, and I'm not sure which one is the most appropriate. I think I'll need to review the AWS security best practices to make sure I understand the differences between security groups, network ACLs, and VPC flow logs.

I'm a bit confused on this one. I know Dimensions can be used to control spacing, but I'm not sure if that's the best option for preserving design intent. I'll have to review my notes.

Hmm, this is a tricky one. I'll need to think carefully about the different network components involved in IPMP and how probe-based failure detection works.

Okay, let's see. Route reflectors and confederations - that's my best guess. I'll mark those and move on.
