Selected Answers: B
The default HTTP health monitor on BIG-IP sends an HTTP request (usually GET /) and expects a 200 OK response.
Any response other than 200 OK (such as 404 Not Found) is treated as a monitor failure.
Given results:
2 pool members return 404 Not Found → ❌ monitor fail → Offline
1 pool member returns 200 OK → ✅ monitor pass → Online
✅ Pool status result:
Two members offline and one member online
This is a classic F5 CAB1 / LTM health monitor question.

El monitor http por defecto en BIG-IP:
Envía una solicitud HTTP GET /
Considera UP solo si la respuesta es 200 OK
Cualquier otro código (como 404 Not Found) se considera DOWN
En tu escenario:
2 pool members responden 404 Not Found → ❌ OFFLINE
1 pool member responde 200 OK → ✅ ONLINE

When you assign the default HTTP health monitor to a pool, it expects a 200 OK response to mark a member as available.
Two members return 404 Not Found → the monitor interprets this as a failure.
One member returns 200 OK → the monitor interprets this as success.
👉 Correct answer: A. Two members offline and one member online.

Since both a 200 OK and a 404 Not Found response return data from the server, the default monitor considers all three responses as successful, marking all pool members as online. To fix this and mark the 404 members offline, an administrator would need to configure a custom HTTP monitor with a specific Receive String (e.g., "200 OK").
A BIG-IP Administrator assigns the default http health monitor to a pool that has three members listening on port 80. When the administrator connects to each pool member via the CURL utility, two of the members respond with a status of 404 Not Found while the third responds with 200 OK. What will the pool show for member availability? (Choose one answer)
