Topic #: 1
[All 70-466 Questions]

You have a SQL Server 2012 instance that hosts a single-user database. The database does not contain user-created stored procedures or user-created functions. You need to minimize the amount of memory used for query plan caching.
Which advanced server option should you modify?

  • A. Enable Contained Databases
  • B. Allow Triggers to Fire Others
  • C. Optimize for Ad hoc Workloads
  • D. Scan for Startup Procs

Suggested Answer: C 🗳️
The optimize for ad hoc workloads option is used to improve the efficiency of the plan cache for workloads that contain many single use ad hoc batches. When this option is set to 1, the Database Engine stores a small compiled plan stub in the plan cache when a batch is compiled for the first time, instead of the full compiled plan. This helps to relieve memory pressure by not allowing the plan cache to become filled with compiled plans that are not reused.
