A BIG-IP Administrator needs to make sure that requests from a single user are directed to the server that was initially selected (unless that server is marked down). What should the administrator con

A caching profile stores and serves static content to reduce server load, but it does not control which server a request is routed to.

A TCP profile configures transport-layer connection behavior such as timeouts and buffer sizes, not session stickiness or server selection.

A persistence profile tracks client connections using methods such as source IP or cookie insertion and forwards repeat requests to the same pool member that handled the initial connection. This is the core mechanism for session persistence on BIG-IP, ensuring stateful applications function correctly. Without it, load balancing would distribute each request independently, potentially breaking session-dependent workflows.

A security policy enforces access control and application firewall rules, not the routing of requests to a specific backend server.
