Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

1. You develop a Microsoft SQL Server 2012 database. The database is used by two web applications that access a table named Products. You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data. You need to ensure that the following requirements are met:
Future modifications to the table definition will not affect the applications' ability to access data.
The new object can accommodate data retrieval and data modification.
You need to achieve this goal by using the minimum amount of changes to the existing applications.
What should you create for each application?

A) table-valued functions
B) table partitions
C) stored procedures
D) views

2. You administer a Microsoft SQL Server 2012 clustered instance that has two nodes named Node 1 and Node 2. Node 1 fails and the cluster fails over to Node 2. You need to replace Node 1 and add it to the cluster. Which four actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Build List and Reorder:

3. You administer several Microsoft SQL Server 2012 database servers. Merge replication has been configured for an application that is distributed across offices throughout a wide area network (WAN). Many of the tables involved in replication use the XML and varchar(max) data types. Occasionally, merge replication fails due to timeout errors. You need to reduce the occurrence of these timeout errors. What should you do?

A) Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
B) Change the Merge agent on the problem subscribers to run continuously.
C) Set the Remote Connection Timeout on the Publisher to 0.
D) Set the Merge agent on the problem subscribers to use the slow link agent profile.

4. You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day. The reporting database is only updated from the transactional database. The recovery model and backup schedule are configured as shown in the following table:

The differential backup of the reporting database fails. Then, the reporting database fails at 14:00 hours.
You need to ensure that the reporting database is restored. You also need to ensure that data loss is minimal. What should you do?

A) Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
B) Perform a page restore.
C) Restore the latest full backup. Then, restore the latest differential backup.
D) Restore the latest full backup.
E) Perform a point-in-time restore.
F) Perform a partial restore.
G) Restore the latest full backup, and restore the latest differential backup. Then, restore each log backup taken before the time of failure from the most recent differential backup.
H) Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.

You need to assign a PartitionNumber for each record in the Customers table. You also need to ensure that the PartitionNumber satisfies the following conditions:
Always starts with 1.
Starts again from 1 after it reaches 100. Which Transact-SQL statement should you use?

A) CREATE SEQUENCE CustomerSequence AS int START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 100 CYCLE UPDATE Customers SET PartitionNumber = NEXT VALUE FOR CustomerSequence
DROP SEQUENCE CustomerSequence
B) CREATE SEQUENCE CustomerSequence AS int START WITH 1 INCREMENT BY 1 MINVALUE 0 MAXVALUE 100 CYCLE UPTATE Customers SET PartitionNumber = NEXT VALUE FOR CustomerSequence DROP SEQUENCE CustomerSequence
C) CREATE SEQUENCE CustomerSequence AS int START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 100 UPDATE Customers SET PartitionNumber = NEXT VALUE FOR CustomerSequence + 1 DROP SEQUENCE CustomerSequence
D) CREATE SEQUENCE CustomerSequence AS int START WITH 0 INCREMENT BY 1 MINVALUE 1 MAXVALUE 100 UPDATE Customers SET PartitionNumber = NEXT VALUE FOR CustomerSequence DROP SEQUENCE CustomerSequence
