Hmm, this is a tricky one. I'm leaning towards option C, but I'm not 100% sure. Maybe I should re-read the question and the code a few more times to make sure I'm not missing anything.

I'm not sure, but I think it might be D because it sends the client to Pool WebClient1 if the IP is NOT on the list.

Ah, I see! The iRule is checking if the client IP is on the whitelist. If it is, it forwards the traffic to the WebClient1 pool. Otherwise, it discards the traffic and logs the invalid IP. Makes sense to me.

I agree with you, Angella. Option C makes the most sense based on the iRule provided.

This iRule is definitely comparing the client IP to a list, but I'm not sure what the intended behavior is. Is it supposed to discard or forward the traffic? I'll need to read it more carefully.

I think the answer is C because it sends the client to Pool WebClient1 if the IP is on the list.
