I'm not sure where you got that question but, it looked an awful lot like one I recieved on my exam. DO NOT post actual questions

You're right! HttpSessionBindingListener causes an object to be notified when it is bound to or unbound from a session. The object is notified by an HttpSessionBindingEvent object. This may be as a result of a servlet programmer explicitly unbinding an attribute from a session, due to a session being invalidated, or die to a session timing out.

...but isn't also option 3 correct? Doesn't a AttributeListener also get notified when a attribute is "implitcly" deleted and "implicitly" added by an unbinding and binding respectively?
