A site would like to ensure that a given web server's default page is being served correctly prior to sending it client traffic. They assigned the default HTTP monitor to the pool. What would the…

A pool member is marked offline (red) for failures such as connection refusal, no response, or an explicitly configured HTTP error status code, not typically for an unexpected but valid response.

A default HTTP monitor primarily validates that the server responds with a valid HTTP status code, typically HTTP 200 OK. If the server sends an 'unexpected response' but it's still a successful HTTP response (e.g., a 200 OK with different content than anticipated), the monitor will consider the web service responsive and mark the pool member as online (green), as it met the basic criteria for availability.

A 'blue' or unknown status typically indicates that the monitor has not yet determined the status or there is an issue with the monitor itself.

The pool member would not alternate between red and green for a single, consistent 'unexpected response'; this behavior usually indicates intermittent network or server issues.
