You are creating a Web Part in SharePoint Server 2010.
You need to ensure that the Web Part can send data to another Web Part.
Which interface should you override?

• A. IQueryable
• B. ISerializable
• C. IWebEditable
• D. IWebPartField

You have a SharePoint site collection. The root Web of the site collection has the URL http://intranet.
You plan to create a user solution that will contain a Web Part. The Web Part will display the title of the root Web.
You write the following code segment for the Web Part. (Line numbers are included for reference only.)
01 SPSite currentSite = new SPSite("http://intranet");
02
03 Label currentTitle = new Label();
04 currentTitle.Text = currentSite.RootWeb.Title;
You add the Web Part to a page in the root Web and receive the following error message: "Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred."
You need to prevent the error from occurring.
What should you do?

• A. Add the following line of code at line 02: currentSite.OpenWeb("http://intranet");
• B. Change line 04 to the following code segment: currentTitle.Text = currentSite.OpenWeb().Title;
• C. Add the following line of code at line 02: currentSite.OpenWeb();
• D. Change line 01 to the following code segment: SPSite currentSite = SPContext.Current.Site;

You have the following event receiver. (Line numbers are included for reference only.)
01 public override void FieldDeleting(SPListEventProperties properties)02 {
03 04
base.FieldDeleting(properties);
05 06 07
if (properties.FieldName == "Status"){
08
09
}
10 }
You need to cancel the operation and redirect the user to a custom error page if the name of the deleted field is Status.
Which code segments should you add at lines 07 and 08?

• A. 04 properties.Status = SPEventReceiverStatus.CancelWithRedirectUrl;05 properties.ReceiverData = "/_layouts/customErrorPage.aspx";
• B. 04 properties.Status = SPEventReceiverStatus.CancelWithRedirectUrl;05 properties.RedirectUrl = "/_layouts/customErrorPage.aspx";
• C. 04 properties.ReceiverData = "/_layouts/customErrorPage.aspx";05 properties.Cancel = true;
• D. 04 properties.RedirectUrl = "/_layouts/customErrorPage.aspx";05 properties.Cancel = true;

You create a Web Part that takes three values from three text boxes and creates a new SharePoint site when you click a button named CreateNewSite.
The Web Part contains the following code segment.
protected void CreateNewSite_Click(object sender, EventArgs e)
{ SPSite site = SPContext.Current.Site;
SPWeb web = site.AllWebs.Add(SiteNameTextBox.Text, SiteTitleTextBox.Text,SiteDescriptionTextBox.Text, 0, SPWebTemplate.WebTemplateSTS, false, false);}
You test the Web Part and it works properly.
When another user attempts to use the Web Part to create a new site, he receives the following error message: "Error: Access Denied."
You need to ensure that users can use the Web Part to create new sites.
What should you do?

• A. Add web.Update()after the code segment.
• B. Run the code segment inside a SPSecurity.RunWithElevatedPrivilegesdelegate.
• C. Add the following code after the code segment:
  SPUser currentUser = System.web.CurrentUser;
  web.Users.Add(currentUser.LoginName, currentUser.Email, currentUser.Name,"");
• D. Add web.ValidatesFormDigest()after the code segment.
