Question
The current status of a given pool is ffline.(red). Which condition could explain that state. Assume the descriptions below include all monitorsThe current status of a given pool is .ffline.(red). Which condition could explain that state. Assume the descriptions below include all monitors assigned for each scenario.
Options
- ANo monitors are currently assigned to any pool, member or node.
- BThe pool has a monitor assigned to it, and none of the pool members passed the test. The pool
- CThe pool has a monitor assigned to it, and only some of the pool's members passed the test.
- DA monitor is assigned to all nodes and all nodes have passed the test. The pool's members have

Why each option
A BIG-IP pool shows Offline (red) status when a monitor is assigned and every pool member fails the health check.
Without any monitors assigned, BIG-IP cannot evaluate member health, so the pool would display an Unknown (blue) status rather than Offline (red).
When a monitor is assigned to a pool and all pool members fail their health checks, BIG-IP marks the pool as Offline (red) because no member is available to receive traffic. This total failure condition is the specific trigger that drives a pool to the red Offline state.
If only some members fail their checks, the pool remains Available (green) because at least one member can still accept traffic and the pool is considered functional.
If all nodes pass their assigned monitors, pool members inherit that availability, and the pool would show as Available (green), not Offline (red).
