Which statement is true concerning cookie persistence?
The correct answer is A. Cookie persistence allows persistence independent of IP addresses. Cookie persistence establishes client affinity by embedding server information in an HTTP cookie, allowing subsequent requests to be directed to the same server even if the client's IP address changes.

Why each option
Cookie persistence establishes client affinity by embedding server information in an HTTP cookie, allowing subsequent requests to be directed to the same server even if the client's IP address changes.
Cookie persistence relies on a unique identifier stored within an HTTP cookie on the client's browser to direct subsequent requests to the original server. This mechanism allows the load balancer to maintain persistence even if the client's source IP address changes during a session.
Cookie persistence requires the load balancer to inspect HTTP headers to manage cookies, which is not possible with end-to-end encryption unless SSL offloading or bridging is performed.
