Which two can be a part of a pool's definition. (Choose two.)

iRules are attached to virtual servers, not pools; they intercept and evaluate traffic before it is forwarded to a pool member.

Profiles such as TCP, HTTP, and SSL are assigned to virtual servers to define how the BIG-IP processes connections, not to pool definitions.

Health monitors are defined directly on a pool to periodically check the availability of each member; BIG-IP uses monitor results to mark members up or down and automatically stops sending traffic to any member that fails its health check. Monitors are a native pool-level object in the BIG-IP configuration hierarchy.

Persistence type is configured on the virtual server because persistence tracking operates at the connection-handling layer above the pool, mapping clients to specific members before pool selection occurs.

The load balancing mode is a required pool property that specifies the algorithm - such as Round Robin, Least Connections, or Ratio - used to select a member for each new connection, and it is set within the pool definition itself.
