Reporting from a Star schema is simpler than reporting from a normalized online
transactional processing (OLTP) schema. What are the reasons for wanting simpler
reporting? (Choose all that apply.)

Selecciona una o más de las siguientes respuestas posibles:

  • A Star schema typically has fewer tables than a normalized schema. Therefore,
    queries are simpler because they require fewer joins.

  • Star schema has better support for numeric data types than a normalized rela-
    tional schema; therefore, it is easier to create aggregates.

  • There are specific Transact-SQL expressions that deal with Star schemas.

  • A Star schema is standardized and narrative; you can find the information you
    need for a report quickly.

You implement a Type 2 solution for an SCD problem for a specific column. What do
you actually do when you get a changed value for the column from the source system?

Selecciona una de las siguientes respuestas posibles:

  • Add a column for the previous value to the table. Move the current value of the
    updated column to the new column. Update the current value with the new value
    from the source system.

  • Insert a new row for the same dimension member with the new value for the
    updated column. Use a surrogate key, because the business key is now duplicated.
    Add a flag that denotes which row is current for a member.

  • Do nothing, because in a DW, you maintain history, you do not update dimen-
    sion data.

  • Update the value of the column just as it was updated in the source system.

How can you spot natural hierarchies in a Snowflake schema?

Selecciona una de las siguientes respuestas posibles:

  • You need to analyze the content of the attributes of each dimension.

  • Lookup tables for each dimension provide natural hierarchies.

  • A Snowflake schema does not support hierarchies.

  • You should convert the Snowflake schema to the Star schema, and then you would
    spot the natural hierarchies immediately.

You need to move data from a production database into a testing database. You need
to extract the data from several objects in the source database, but your manager
has asked you to only copy about 10 percent of the rows from the largest production
tables. The testing database already exists, but without any tables. How would you ap-
proach this task?

Selecciona una o más de las siguientes respuestas posibles:

  • Use the Import and Export Wizard, copy all tables from the source database to the
    empty destination database, and delete the excess rows from the largest tables.

  • Use the Import and Export Wizard multiple times—once for all the smaller tables,
    and once for each large table, using the Write A Query To Specify The Data To
    Transfer option to restrict the rows

  • Use the Import and Export Wizard, copy all tables from the source database to the
    empty destination database, and restrict the number of rows for each large table
    by using the Edit SQL option in the Column Mappings window

  • Use the Import and Export Wizard, configure it to copy all tables from the source
    database to the empty destination database, save the SSIS package, and then,
    before executing it, edit it by using SSDT to restrict the number of rows extracted
    from the large tables.

You need to move data from an operational database into a data warehouse for the
very first time. The data warehouse has already been set up, and it already contains
some reference data. You have just finished preparing views in the operational data-
base that correspond to the dimension and fact tables of the data warehouse. How
would you approach this task?

Selecciona una o más de las siguientes respuestas posibles:

  • Use the Import and Export Wizard and copy data from the dimension and fact
    views in the operational database into the tables in the data warehouse, by using
    the Drop And Re-create The Destination Table option in the Column Mappings
    window for every non-empty destination table.

  • Use the Import and Export Wizard, configure it to copy data from the dimension
    and fact views in the operational database into the tables in the data warehouse,
    save the SSIS package, and then edit it by using SSDT to add appropriate data
    merging functionalities for all destination tables.

  • Use the Import and Export Wizard and copy data from the dimension and fact
    views in the operational database into the tables in the data warehouse, by using
    the Merge Data Into The Destination Table option in the Column Mappings win-
    dow for every non-empty destination table.

  • Use SSDT instead of the Import and Export Wizard, because the wizard lacks ap-
    propriate data transformation and merging capabilities

You need to execute two data flow operations in parallel after an Execute SQL Task has
been completed. How can you achieve that? (Choose all that apply.)

Selecciona una o más de las siguientes respuestas posibles:

  • There is no way for two data flow operations to be executed in parallel in the same
    SSIS package.

  • You can place both data flows inside the same data flow task and create a prece-
    dence constraint leading from the preceding Execute SQL Task to the data flow task.

  • You can create two separate data flow tasks and create two precedence constraints
    leading from the preceding Execute SQL Task to each of the two data flow tasks.

  • You can create two separate data flow tasks, place them inside a third data flow
    task, and create a precedence constraint leading from the preceding Execute SQL
    Task to the third data flow task.

Some of the data your company processes is sent in from partners via email.
How would you configure an SMTP connection manager to extract files from email
messages?

Selecciona una de las siguientes respuestas posibles:

  • In the SMTP connection manager, configure the OperationMode setting to Send
    And Receive.

  • It is not possible to use the SMTP connection manager in this way, because it can
    only be used by SSIS to send email messages.

  • The SMTP connection manager supports sending and receiving email messages by
    default, so no additional configuration is necessary.

  • It is not possible to use the SMTP connection manager for this; use the IMAP (In-
    ternet Message Access Protocol) connection manager instead.

In your SSIS solution, you need to load a large set of rows into the database as quickly
as possible. The rows are stored in a delimited text file, and only one source column
needs its data type converted from String (used by the source column) to Decimal
(used by the destination column). What control flow task would be most suitable for
this operation?

Selecciona una de las siguientes respuestas posibles:

  • The File System task would be perfect in this case, because it can read data from
    files and can be configured to handle data type conversions.

  • The Bulk Insert task would be the most appropriate, because it is the quickest and
    can handle data type conversions.

  • The data flow task would have to be used, because the data needs to be trans-
    formed before it can be loaded into the table.

  • No single control flow task can be used for this operation, because the data needs
    to be extracted from the source file, transformed, and then loaded into the desti-
    nation table. At least three different tasks would have to be used—the Bulk Insert
    task to load the data into a staging database, a Data Conversion task to convert
    the data appropriately, and finally, an Execute SQL task to merge the transformed
    data with existing destination data.

A part of your data consolidation process involves extracting data from Excel work-
books. Occasionally, the data contains errors that cannot be corrected automatically.
How can you handle this problem by using SSIS?

Selecciona una de las siguientes respuestas posibles:

  • Redirect the failed data flow task to an External Process task, open the problematic
    Excel file in Excel, and prompt the user to correct the file before continuing the
    data consolidation process.

  • Redirect the failed data flow task to a File System task that moves the erroneous
    file to a dedicated location where an information worker can correct it later.

  • If the error cannot be corrected automatically, there is no way for SSIS to continue
    with the automated data consolidation process.

  • None of the answers above are correct. Due to Excel’s strict data validation rules,
    an Excel file cannot ever contain erroneous data.

How is the order of execution, or the sequence of operations, defined in an SSIS
package?

Selecciona una de las siguientes respuestas posibles:

  • The SSIS run time engine determines the order of execution automatically, based
    on the type of operations, the available software and hardware resources, and the
    size of data.

  • The sequence is defined by using precedence constraints.

  • The sequence is defined by using the Sequence container.

  • The sequence is defined at design time by using precedence constraints and
    Sequence containers, but at run time the SSIS engine executes the operations in
    the order set by the most appropriate execution plan for maximum performance.

How does the Failure constraint affect the execution order?

Selecciona una de las siguientes respuestas posibles:

  • The following task will only execute after the preceding task has failed.

  • The following task will only execute if the preceding task has not failed.

  • The following task will never execute, because this constraint is only used at
    design time.

  • The following task will execute regardless of whether the preceding task has failed,
    but an error will be written to the SSIS log.

In your ETL process, there are three external processes that need to be executed in
sequence, but you do not want to stop execution if any of them fails. Can this be
achieved by using precedence constraints? If so, which precedence constraints can
be used?

Selecciona una de las siguientes respuestas posibles:

  • No, this cannot be achieved just by using precedence constraints.

  • Yes, this can be achieved by using completion precedence constraints between the
    first and the second and between the second and the third Execute Process tasks,
    and by using a success precedence constraint between the third Execute Process
    task and the following task.

  • Yes, this can be achieved by using completion precedence constraints between
    the first and the second, between the second and the third, and between the third
    Execute Process task and the following task.

  • Yes, this can be achieved by using failure precedence constraints between the first
    and the second, and between the second and the third Execute Process tasks, and

In the control flow of your SSIS package, you need to add a data maintenance task that
will rebuild the indexes of your dimension tables after they have been populated suc-
cessfully. You have implemented each dimension table load in an individual data flow.
The Execute SQL task containing the index rebuild script must be executed after the
preceding data flow has completed successfully, but only on Saturdays. The name of
the current day is stored in a variable. Is it possible to achieve this in SSIS control flow?
If so, how?

Selecciona una o más de las siguientes respuestas posibles:

  • No, this is not possible in the control flow because the conditional split transforma-
    tion is only available in a data flow.

  • Yes, it is possible to achieve this in the control flow, but only by using a Script task.

  • Yes, this can be achieved by using a success precedence constraint leading from
    the data flow task to the Execute SQL task, with a precedence constraint expression
    checking whether the value of the variable is Saturday.

  • Yes, this can be achieved by using a regular success precedence constraint leading
    from the data flow task to the Execute SQL task.
