You have 3 SharePoint Server 2010 Service Pack 1 (SP1) server farm. The farm contains a publishing
site collection. You have a page that contains a Content Query Web Part. The Content Query Web
Part displays all items that use the task content type in the site collection. Users report that when
they add new task items to the site collection, the tasks take up to one minute to appear in the
Content Query Web Part. You need to reduce the amount of time it takes for the new tasks to
appear in the Content Query Web Part. What should you do?
A.
Edit the site collection object cache.
B.
Activate the BLOB cache.
C.
Edit the list view threshold.
D.
Activate the site collection output cache.
