How does Option D even remove non-digits?

I’m a bit confused about the syntax in these options. I hope I remember the right regex for digits when I see it!

I feel like Option C looks familiar, but I can't recall if it correctly captures all non-digit characters.

I remember practicing a similar question where we had to filter out characters. I think it was about using `.replace()` with a regex.

I think we need to use a regex pattern that matches non-digit characters, but I'm not sure which method to use for removal.

I think Option C is the way to go here. The regular expression looks clear and easy to understand, and the replace() method should do the job nicely. I'm confident I can implement this solution correctly.

Option D seems like the most verbose solution, so I'm going to rule that one out. I'm leaning towards Option B or C, but I'll need to double-check the documentation to make sure I'm using the right method to remove the non-digit characters.

Hmm, I'm a bit unsure about this one. I'll need to carefully review the regular expression syntax to make sure I understand how it works. Maybe I'll try a few test cases to see which option works best.

This looks like a straightforward regular expression problem. I think I'll go with Option B - it looks like the most concise and efficient way to remove the non-digit characters.

Hmm, I'm a bit confused. Is this a unique value map with multiple fields, or is it a proportional symbol map? I'll have to think this through carefully.

I practiced a question similar to this where we used the docker service update command. It really seems like we should choose parallel upgrades or rolling updates, but I'm leaning towards C for sure.

Okay, I think I've got it. The security policy only allows controller web management traffic from the IT subnet, so the issue must be that the guest wireless traffic is being blocked. I'll go with option D.

I'm a bit confused by the wording of the question. Are informal controls and procedural controls the same thing? I'll have to re-read the question a few times to make sure I understand it correctly.
