That is a question that may be coming back under close scrutiny. Few observers maintain that any response could have arrived in time to save Ambassador Chris Stevens and Sean Smith, who died in the initial attack at the consulate. The question remain, however, since the incident lasted 8 hours and moved to the annex building, whether the other two victims could have been rescued. In the below link, investigative reporter Sheryl Attkisson argues that a number of military assets could have arrived in time, but for some reason, never entered Libya.
Apparently, Trey Gowdy (R-SC), who heads up the select committee investigating Benghazi, has also been told by several sources that those assets were not allowed to proceed to Libya.
In addition, three of the men who were at the annex when the attack began have publicly stated ( on Sean Hannity's Fox show) that a CIA supervisor at the annex ordered them not to proceed to the consulate.
