You administer a Microsoft SQL Server database server. One of the databases on the server supports a highly active OLTP application.

Users report abnormally long wait times when they submit data into the application. You need to identify which queries are taking longer than 1 second to run over an extended period of time.

Correct Answer:

Explanation:

Starting with the update to Microsoft SQL Server 2012 Service Pack 1, customers with SQL Server 2012 failover cluster instances can greatly benefit from the fully automated update process provided by Cluster-Aware Updating (CAU). CAU causes minimal down time for SQL Server 2012 client connectivity. While the primary node is being updated, the SQL Server clustered role (also called the resource group) goes through two failovers. The first failover happens before updating the primary node when CAU brings the original primary node into maintenance mode. During the update process on the original primary node, the SQL clustered role is temporarily brought online on a new primary node. The second failover happens once the update process is complete on the original primary node, and CAU fails back the SQL Server clustered role to the original primary node and brings it online.

You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).

The financial database has the following characteristics:

– A data file of 2 terabytes is located on a dedicated LUN (drive D).

– A transaction log of 10 GB is located on a dedicated LUN (drive E).

– Drive D has 1 terabyte of free disk space.

– Drive E has 5 GB of free disk space.

The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.

The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.

These data load operations must occur in the minimum amount of time.

A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.

You need to ensure that your backup will continue if any invalid checksum is encountered.

Which backup option should you use?
