Nope, -D is for deleting specific rules, not all.

I’m a bit confused about the -h option; I think it’s for help, but I can't recall if it has any other function related to removing rules.

I feel like -A is for adding rules, so it can't be the answer here. I think -F is the one we need.

I think I remember that to flush all rules from the chains, we might use the -F option, but I'm not completely sure.

I recall that -A is for adding rules, so that can't be the right answer. I think -F is definitely the one we need here.

I’m a bit confused because I thought -D was for deleting specific rules, but now I’m not sure how that fits in with removing all rules.

I practiced a similar question where we had to clear the rules, and I believe the command was IPTABLES -F. It makes sense to flush them all at once.

I think I remember that to flush all rules, you use a command that starts with -F, but I'm not entirely sure if it's the right one for removing all rules.

I'm a bit confused on this one. I know cloud scripts use some kind of scripting language, but I'm not sure if it's shell, PowerShell, JavaScript, or something else. I'll have to think this through carefully.

Ah, I think I've got it! A Display Business Rule can't access the GlideSystem object. That's the one it doesn't have access to.
