You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads data from a source system that uses the SQL Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete operations.
Which data flow transformation should you use?

Note: This question is part of a series of questions that use the same set of answer choices. An answer choice may be correct for more than one question in the series.
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: One of the hard disk drives chat stores the transactional database fails at 23:32 hours. Attempts to create a tail log backup are unsuccessful.

You need to ensure that the transactional database is restored. You also need to ensure that data loss is minimal,

HOTSPOT
You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads rows from a source system and compares them to rows in a destination system. New rows will be inserted and changed rows will be updated.
You have used a Lookup transformation and a Conditional Split transformation. The Lookup transformation joins the source and destination table on the business key, and includes all columns from the destination table in the data flow output. The Conditional Split transformation inspects the destination columns and directs data flow to either insert new records or update existing records.
You need to configure the Lookup transformation to ensure that all records flow to the Conditional Split transformation, regardless of whether the rows match an existing row in the destination table.
Which setting should you select? (To answer, select the appropriate option in the answer area.)

Correct Answer:
DRAG DROP
You administer three Microsoft SQL Server 2012 servers named ServerA, Servers, and ServerC.
ServerA is the acting principal and ServerB is the mirror.
You need to add ServerC as a witness to the existing mirroring session between ServerA and ServerB. You need to achieve this goal without delaying synchronization.
Which three 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.)
Correct Answer:
You administer a Microsoft SQL Server 2012 server. You plan to deploy new features to an application.
You need to evaluate existing and potential clustered and non-clustered indexes that will improve performance.

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 S 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 implement log shipping of the financial database to another SQL Server 2012 instance. You decide to failoverto this secondary database.
You need to ensure that all transactions will be replicated to the secondary database.
Which backup option should you use?

You are developing a SQL Server Integration Services (SSIS) project by using the Project Deployment model. A package in the project extracts data from a Windows Azure SQL Database database. The package is deployed to SQL Server.
The package is not producing the desired results.
You need to generate the .mdmp and .tmp debug files in order to troubleshoot the issues.

You are developing a SQL Server Integration Services (SSIS) package.
The package uses a data flow task to source data from a SQL Server database for loading into a dimension table in a data warehouse.
You need to create a separate data flow path for data that has been modified since it was last processed.
Which data flow components should you use to identify modified data? (Each correct answer presents a complete solution. Choose all that apply.)
