D.

Explanation:
The Class of Restrictions (COR) feature provides the ability to deny certain call attempts
based on the incoming and outgoing CORs provisioned on the dial-peers. COR is used to specify which
incoming dial-peer can use which outgoing dial-peer to make a call. Each dial-peer can be provisioned
with an incoming and an outgoing COR list.
<Rule> If the COR applied on an incoming dial-peer (for incoming calls) is a super set or equal to the
COR applied to the outgoing dial-peer (for outgoing calls), the call goes through.
Based on the rule, B and C are correct. In addition, Extension 1010 is able to call 911 and other IP phones
such as 1011,1012 but NOT 1013. Extension 1012 can be called by Executives,external callers,as well as
Lobby and Staff.
