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

Rules, such as iRules, are typically associated with virtual servers, not directly configured within a pool's definition, to apply custom logic to traffic flow.

Profiles are usually assigned to virtual servers to enable specific network or application protocol features (e.g., HTTP, SSL), rather than being a direct part of a pool's definition.

Health monitors are integral to a pool's definition, as they continuously assess the operational status and health of pool members, ensuring traffic is only sent to functional servers.

Persistence types are commonly configured on virtual servers (often via persistence profiles) to maintain client-server affinity for a series of connections, not as a direct property of the pool itself.

The load balancing mode is a core component of a pool's definition, determining the algorithm (e.g., Round Robin, Least Connections) used to distribute incoming client connections among its member servers.
