4. Given the two security constraints in a deployment descriptor:
1 01. <security-constraint>
1 02. <!--a correct url-pattern and http-method goes here-->

1 03. <auth-constraint>
1 04. <role-name>SALES</role-name>
1 05. </auth-constraint>
1 06. </security-constraint>
1 07. <security-constraint>
1 08. <!--a correct url-pattern and http-method goes here-->
1 09. <!-- Insert an auth-constraint here -->
1 10. </security-constraint>
If the two security constraints have the same url-pattern and http-method, which two, inserted independently at line 109, will allow users with role names of either SALES or
MARKETING to access this resource? (Choose two.)

A) <auth-constraint>
< role-name>ANY</role-name>
