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

iRules, referred to as rules, can be directly associated with a virtual server to provide highly customizable traffic management and content manipulation capabilities.

A virtual server is fundamentally designed to forward client traffic to a pool, which is a logical group of backend servers, making pools a core part of its definition.

Monitors are typically associated with pools or individual pool members to check their health, not directly with the virtual server itself.

Node addresses are defined independently and then utilized within pools as pool members; they are not directly configured as part of a virtual server's definition.

The load balancing method is an attribute configured on a pool to determine how traffic is distributed among its members, not directly on the virtual server.
