Given the security constraint in a DD：
101.<security-constraint>
102.<web-resource-collection>
103.<web-resource-name>Foo</web-resource-name>
104.<url-pattern>/Bar/Baz/*</url-pattern>
105.<http-method>POST</http-method>
106.</web-resource-collection>
107.<auth-constraint>
108.<role-name>DEVELOPER</role-name>
109.</auth-constraint>
110.</security-constraint>
And given that "MANAGER" is a valid role-name，which four are true for this security constraint？（）
A.MANAGER can do a GET on resources in the /Bar/Baz directory.
B.MANAGER can do a POST on any resource in the /Bar/Baz directory.
C.MANAGER can do a TRACE on any resource in the /Bar/Baz directory.
D.DEVELOPER can do a GET on resources in the /Bar/Baz directory.
E.DEVELOPER can do only a POST on resources in the /Bar/Baz directory.
F.DEVELOPER can do a TRACE on any resource in the /Bar/Baz directory.
Given this fragment in a servlet：
23.if（req.isUserInRole（"Admin"）） {
24.// do stuff
25.}
And the following fragment from the related Java EE deployment descriptor：
812.<security-role-ref>
813.<role-name>Admin</role-name>
814.<role-link>Administrator</role-link>
815.</security-role-ref>
900.<security-role>
901.<role-name>Admin</role-name>
902.<role-name>Administrator</role-name>
903.</security-role>
What is the result？（）
A.Line 24 can never be reached.
B.The deployment descriptor is NOT valid.
C.If line 24 executes， the user’s role will be Admin.
D.If line 24 executes， the user’s role will be Administrator.
E.If line 24 executes the user’s role will NOT be predictable.

Given：
3.class MyServlet extends HttpServlet {
4.public void doPut（HttpServletRequest req， HttpServletResponse resp） throws ServletException，IOException {
5.// servlet code here ...
26.}
27.}
If the DD contains a single security constraint associated with MyServlet and its only <http method> tagsand <auth-constraint> tags are：<http-method>GET</http-method><http-method>PUT</http-method>
<auth-constraint>Admin</auth-constraint>
Which four requests would be allowed by the container？（）
A.A user whose role is Admin can perform a PUT.
B.A user whose role is Admin can perform a GET.
C.A user whose role is Admin can perform a POST.
D.A user whose role is Member can perform a PUT.
