Identify the reason a pool is not working as expected

Question Image

Refer to the exhibit.

A BIG-IP Administrator observes that one server running an application is not receiving any traffic. The administrator reviews the application’s configuration status and sees the shown monitor configuration and affected Pool Member status.

What is a possible cause of this issue?

  • A The Node Health Monitor is NOT responding.
  • B HTTP 1.1 is NOT appropriate for monitoring purposes.
  • C The BIG-IP device is NOT able to reach the Pool Member.
  • D The application is NOT responding with the expected Receive String.
Explanation

A pool member whose status is Offline (Enabled) - Parent down is unavailable because its parent node has been marked down. BIG-IP applies node health status to pool members that use that node’s IP address; therefore, a nonresponding node health monitor can cause the member to receive no new traffic even when the member-level HTTPS monitor is available.
