Given that a scoped attribute cart exists only in a user's session, which two, taken independently, ensure the scoped attribute cart no longer exists? (Choose two.)

• B.<c:remove var="cart" />
• C.<c:remove scope="session">${cart}</c:remove>
• D.<c:remove var="cart" scope="session" />
• E.<c:remove var="${cart}" scope="session" />

Given the two security constraints in a deployment descriptor:
101.
<security-constraint>
102.
<!--a correct url-pattern and http-method goes here-->
103.
<auth-constraint><role-name>SALES</role-name></auth-
103.
<auth-constraint>
104.
<role-name>SALES</role-name>
105.
</auth-constraint>
106.
</security-constraint>
107.
<security-constraint>
108.
<!--a correct url-pattern and http-method goes here-->
109.
<!-- Insert an auth-constraint here -->
110.
</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/>
• B.<auth-constraint> <role-name>*</role-name> </auth-constraint>
• C.<auth-constraint> <role-name>ANY</role-name> </auth-constraint>
• D.<auth-constraint> <role-name>MARKETING</role-name> </auth-constraint>

You are creating a servlet that generates stock market graphs. You want to provide the web browser with precise information about the amount of data being sent in the response stream. Which two HttpServletResponse methods will you use to provide this information? (Choose two.)

• A.response.setIntHeader("Length", numberOfBytes);
• B.response.setLength(numberOfBytes);
• C.response.setHeader("Content-Length", numberOfBytes);
• D.response.setIntHeader("Content-Length", numberOfBytes);
• E.response.setHeader("Length", numberOfBytes);
• F.response.setContentLength(numberOfBytes);

A developer for the company web site has been told that users may turn off cookie support in their browsers. What must the developer do to ensure that these customers can still use the web application?

• A.The developer must ensure that every URL is properly encoded using the appropriate URL rewriting APIs.
• B.The developer must provide an alternate mechanism for managing sessions and abandon the HttpSession mechanism entirely.
• C.The developer must add the string ?id=<sessionid> to the end of every URL to ensure that the conversation with the browser can continue.
• D.The developer can ignore this issue. Web containers are required to support automatic URL rewriting when cookies are not supported.
