Seems odd, but I guess that's how it works with health monitors.

I thought it would show all members as down if any return 404.

Wait, so the pool still shows one member available even with 404s?

That’s right! 200 OK means it's good to go.

Only one member is healthy, so the pool will show one available.

The pool will show 100% member availability, because the health monitor is only looking for a response, not a specific status code. 404 is still a valid response.

I'd say the pool will show 33.33% member availability, since only one out of the three members is considered healthy.

Haha, looks like the BIG-IP admin needs to double-check their pool configuration and make sure all members are set up correctly.

Hmm, the health monitor is checking for a 200 OK response, so the pool will only consider the member that responded with 200 OK as available.

The pool will show 66.67% member availability, as two out of the three members are not responding with a 200 OK status.

I feel like there might be exceptions based on the monitor settings, but generally, I think the pool will show only one member as available.

This seems similar to a practice question we did on health monitors. If I recall correctly, only the member returning 200 OK would be marked as available.

I'm not entirely sure, but I remember something about how a 404 response might still count as healthy in some configurations.

I think the health monitor checks for a successful response, so only the member with 200 OK should be considered available, right?

Sounds good. I'll make sure to walk through the health monitor logic step-by-step to arrive at the right answer.

I think I've got it. Since the health monitor is looking for a 200 OK, and only one member is returning that, the pool will likely show that member as available and the other two as unavailable.

I'm a bit confused - if one member is responding with 200 OK, shouldn't that mean the pool shows that member as available?

Okay, so the default http health monitor is checking for a 200 OK response, right? If two members are returning 404, that means they're not passing the health check.

Hmm, this seems like a tricky one. I'll need to think through the health monitor logic carefully.
