If a client's browser does not accept cookies, what occurs when the client connects to a virtual server using cookie persistence.
The correct answer is C. The connection request is loadbalanced to an available pool member.. When a client's browser does not accept cookies, BIG-IP cannot maintain cookie persistence and falls back to standard load balancing for that connection.

Why each option
When a client's browser does not accept cookies, BIG-IP cannot maintain cookie persistence and falls back to standard load balancing for that connection.
The connection request is still processed by BIG-IP; the inability to set a cookie only affects session persistence, not whether the request is accepted and forwarded.
BIG-IP does not redirect the request to an apology server when cookies are unavailable - it handles the connection normally through load balancing.
If a client refuses cookies, the BIG-IP system has no way to store or read a persistence record for that client, so it treats the connection as a new session with no persistence in effect. The request is then distributed to an available pool member using the configured load balancing algorithm, just as it would be without any persistence profile.
BIG-IP does not refuse the connection or return an error message when a client does not accept cookies; the request proceeds without persistence.
Concept tested: F5 cookie persistence fallback to load balancing
