I think they might be looking for verification also, which is where you can see: Graceful Restart Capability: advertised E. Issue the show ip bgp neighbors command.

Selected Answer: D

I think it is only D. Although a reload of the router would also work, it is not necessary to do that, you only need to restart the BGP session/s with "clear ip bgp *" If you enter this command after the BGP session has been established, you must restart the session in order for the capability to be exchanged with the BGP neighbor.
