QUESTION 22

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:

 

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

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

Ÿ   Drive D has 1 terabyte of free disk space.

Ÿ   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?

QUESTION 26

DRAG DROP

You are developing a SQL Server Integration Services (SSIS) package that imports data into a data

warehouse. You are developing the part of the SSIS package that populates the ProjectDates

dimension table. The business key of the ProjectDates table is the ProjectName column. The

business user has given you the dimensional attribute behavior for each of the four columns in

the ProjectDates table:

 

Ÿ   ExpectedStartDate – New values should be tracked over time.

Ÿ   ActualStartDate – New values should not be accepted.

Ÿ   ExpectedEndDate – New values should replace existing values.

Ÿ   ActualEndDate – New values should be tracked over time.

 

You use the SSIS Slowly Changing Dimension Transformation. You must configure the Change

Type value for each source column. Which settings should you select?

 

To answer, select the appropriate setting or settings in the answer area.

 

Select and Place:

clip_image001

 

Correct Answer:

clip_image002

 

 

 

 

 

QUESTION 27

You are developing a data flow transformation to merge two data sources. One source contains

product data and the other source contains data about the country in which the product was

manufactured. Both data sources contain a two-character CountryCode column and both use SQL

Server. Both data sources contain an ORDER BY clause to sort the data by the CountryCode

column in ascending order. You use a Merge Join transformation to join the data.

transformations. What should you do? (Each answer presents a part of the solution. Choose all

that apply.)
