An LTM object contains both IP address and port combinations 20.18.9.250:80 and 20.18.9.251:80 and host the same Web application. What is this object?

A Pool is the F5 BIG-IP object that logically groups multiple pool members - each defined by a unique IP:port pair - that serve the same application, and load balancing decisions are made across these members. Traffic arriving at a virtual server is distributed among the pool's members according to the configured load balancing method. The two entries 20.18.9.250:80 and 20.18.9.251:80 are individual pool members contained within this single pool.

A Self-IP is an IP address assigned to a BIG-IP network interface for routing and management purposes, not an object that groups application server endpoints.

A Node represents only the IP address of a back-end server without a port, and is a lower-level component used to define pool members rather than an object that contains multiple IP:port pairs.

A Pool Member is a single IP:port endpoint representing one server instance, not an object that contains or groups multiple IP:port combinations.

A Virtual Server is the front-end IP:port address that clients connect to on the BIG-IP itself, not a back-end object grouping application servers.
