1. Configure the SqlMembershipProvider in the web.config file.
2. Configure the SqlProfileProvider in the web.config file.

Question: You are creating an ASP.NET Web site. You create a HTTP module named CustomModule, and you register the module in the web.config file. The CustomModule class contains the following code. public class CustomModule : IHttpModule {string footerContent = “<div>Footer Content</div>”; public void Dispose( ) {} } You need to add code to CustomModule to append the footer content to each processed ASP.NET page. Which code segment should you use?

1. public CustomModule(HttpApplication app) {app.EndRequest += new EventHandler(app_EndRequest); } void app_EndRequest(object sender, EventArgs e) {HttpApplication app = sender as HttpApplication;app.Response.Write(footerContent); }
2. public void Init(HttpApplication app) {app.EndRequest += new EventHandler(app_EndRequest); } void app_EndRequest(object sender, EventArgs e) {HttpApplication app = new HttpApplication();app.Response.Write(footerContent); }
3. public CustomModule() {HttpApplication app = new HttpApplication();app.EndRequest += new EventHandler(app_EndRequest); } void app_EndRequest(object sender, EventArgs e) {HttpApplication app = sender as HttpApplication;app.Response.Write(footerContent); }
4. public void Init(HttpApplication app) {app.EndRequest += new EventHandler(app_EndRequest); } void app_EndRequest(object sender, EventArgs e) {HttpApplication app = sender as HttpApplication;app.Response.Write(footerContent); }

2. Add the following configuration to the web.config file. <system.web><customErrors redirectMode=”ResponseRewrite”mode=”On” defaultRedirect=”~/Error.aspx” /> </system.web>
3. Add the following code segment to the Global.asax file. void Application_Error(object sender, EventArgs e) {Response.Redirect(“~/Error.aspx”); }

Question: You are implementing an ASP.NET Web site. The site uses a component that must be dynamically configured before it can be used within site pages. You create a static method named SiteHelper.Configure that configures the component. You need to add a code segment to the Global.asax file that invokes the SiteHelper.Configure method the first time, and only the first time, that any page in the site is requested. Which code segment should you use?

1. void Application_Start(object sender, EventArgs e) {SiteHelper.Configure (); }
2. void Application_Init(object sender, EventArgs e) {SiteHelper.Configure (); }
3. void Application_BeginRequest(object sender, EventArgs e) {SiteHelper.Configure (); } Object lockObject = new Object();
4. void Application_BeginRequest(object sender, EventArgs e) {lock(lockObject){SiteHelper.Configure ();} }
