Agreed, I think Option C is the way to go. Now let's just hope the exam doesn't throw us a curveball and have a trick answer!

I'm still a bit confused, but I think Option C makes the most sense based on the information provided. The question specifically mentions 'alt-src-host', so that seems like the right command to use.

Ha, I just had a thought - maybe we could use the 'alt-src-host' command to set the new interface as a delivery candidate, and then use the 'loadbalance auto' command to spread the load across all the interfaces. That could be a clever solution!

A: Option C seems reasonable, but have you considered Option D as well?
