第1题：

You are implementing an ASP.NET application that uses data-bound GridView controls in multiple pages. You add JavaScript code to periodically update specific types of data items in these GridView controls. You need to ensure that the JavaScript code can locate the HTML elements created for each row in these GridView controls， without needing to be changed if the controls are moved from one page to another. What should you do？（）

• B、Set the ClientIDMode attribute to Predictable in the web.config file.
• C、Set the ClientIDRowSuffix attribute of each unique GridView control to a different value.
• D、Set the @ OutputCache directives VaryByControl attribute to the ID of the GridView control.

第2题：

Your web application requires the adding and deleting of many session attributes during a complex usecase. A bug report has come in that indicates that an important session attribute is being deleted too soonand a NullPointerException is being thrown several interactions after the fact. You have decided to create asession event listener that will log when attributes are being deleted so you can track down when theattribute is erroneously being deleted. Which listener class will accomplish this debugging goal？（）

• A、Create an HttpSessionAttributeListener class and implement the attributeDeleted method and log the attribute name using the getName method on the event object.
• B、Create an HttpSessionAttributeListener class and implement the attributeRemoved method and log the attribute name using the getName method on the event object.
• C、Create an SessionAttributeListener class and implement the attributeRemoved method and log the attribute name using the getAttributeName method on the event object.
• D、Create an SessionAttributeListener class and implement the attributeDeleted method and log the attribute name using the getAttributeName method on the event object.

One of the use cases in your web application uses many session-scoped attributes. At the end of the usecase，you want to clear out this set of attributes from the session object. Assume that this static variableholds this set of attribute names： 201.private static final Set USE_CASE_ATTRS；  202.static { 203.USE_CASE_ATTRS.add（"customerOID"）； 204.USE_CASE_ATTRS.add（"custMgrBean"）； 205.USE_CASE_ATTRS.add（"orderOID"）； 206.USE_CASE_ATTRS.add（"orderMgrBean"）； 207.} Which code snippet deletes these attributes from the session object？（）

• A、session.removeAll（USE_CASE_ATTRS）；
• B、for （ String attr ： USE_CASE_ATTRS ） {session.remove（attr）；}
• C、for （ String attr ： USE_CASE_ATTRS ） {session.removeAttribute（attr）；}
• D、for （ String attr ： USE_CASE_ATTRS ） {session.deleteAttribute（attr）；}
• E、session.deleteAllAttributes（USE_CASE_ATTRS）；

第6题：

Users of your web application have requested that they should be able to set the duration of their sessions.So for example， one user might want a webapp to stay connected for an hour rather than the webapp’sdefault of fifteen minutes； another user might want to stay connected for a whole day. Furthermore， youhave a special login servlet that performs user authentication and retrieves the User object from the database. You want to augment this code to set up the user’s specified session duration. Which codesnippet in the login servlet will accomplish this goal？（）

• A、User user = // retrieve the User object from the database session.setDurationInterval（user.getSessionDuration（））；
• B、User user = // retrieve the User object from the database session.setMaxDuration（user.getSessionDuration（））；
• C、User user = // retrieve the User object from the database session.setInactiveInterval（user.getSessionDuration（））；
• D、User user=//retrieve the User object from the database session.setDuration（user.getSessionDuratio（））；
