I think three failures is a bit harsh for "unhealthy."

Health checks run every 10 seconds, that's correct.

I’m pretty confident that three failed checks transitioning to unhealthy is standard, but I can't recall if the interval is always ten seconds.

I feel like the health check timing could vary based on the service. I need to double-check if it's always ten seconds in Docker Compose files.

I remember a similar question where the health check was defined with different intervals. I think three failed checks is a common threshold, so it might be correct.

I think the health check interval is indeed set to ten seconds, but I'm not sure about the number of failed checks needed to mark it as unhealthy.

I'm a bit confused on this one. All of the options sound like they could be valid task management functions. I'll have to really think this through carefully before selecting an answer.

I've got a good feeling about this one. Based on my understanding of the ADM process, the Implementation and Migration Plan is coordinated in Phase C. But I'll double-check to be sure.

Hmm, I'm not entirely sure about this one. I'll need to think it through carefully. The options seem similar, so I want to make sure I don't miss anything.
