You administer a Microsoft SQL Server 2012 database that includes a table named Application.Events.Application.Events contains millions of records about user activity in an application.
Records in Application.Events that are more than 90 days old are purged nightly. When records are purged,
table locks are causing contention with inserts.
You need to be able to modify Application.Events without requiring any changes to the applications that utilize
Application.Events.
Which type of solution should you use?

A.
Partitioned tables

B.
Online index rebuild

C.
Change data capture

D.
Change tracking

Explanation:
Partitioning large tables or indexes can have manageability and performance benefits including:
You can perform maintenance operations on one or more partitions more quickly. The operations are more
efficient because they target only these data subsets, instead of the whole table.
