You are developing a site-provisioning engine for a company. You create a site request page that employees
use to specify the site template, title, and URL for a site. The site request page stores site requests in a list
named Site Requests that is at the root of the site collection. You configure an approval workflow for the list.
Site creation must start at 3:00 AM each day. You must create sites in batches of no more than 10 sites. You
must not create sites until they are approved.
You need to create the site-provisioning engine.
Which two actions would you perform? Each correct answer presents part of the solution.

A.
Create an ItemUpdated event receiver for the Site Requests list. Initiate site provisioning if the value of the
ModerationInformation property is set to the value SPModerationStatusType.Approved.

B.
Create a new timer job that derives from SPWorkItemJobDefinition. Schedule the timer job to run at 3:00
AM.

C.
Create a new timer job that derives from SPJobDefinition. Schedule the timer job to run at
3:00 AM.

D.
Create an ItemAdded event receiver for the Site Requests list. Initiate site provisioning if the value of the
ModerationInformation property is set to the value SPModerationStatusType.Approved.

E.
Create an ItemUpdated event receiver for the Site Requests list. Create a new work item if the value of the
ModerationInformnation property is set to the value SPModerationStatusType.Approved.

Explanation:

queue where you add list items that need to be processed. When the Work Item Timer Job runs, it pulls items
from the queue and process the item.
