Prepare With New Microsoft 70-767 Practice Questions

QUESTION 1
You are developing a SQL Server Integration Services (SSIS) package. An Execute SQL task in the package checks
product stock levels and sets a package variable named InStock to TRUE or FALSE depending on the stock level
found.
After the successful execution of the Execute SQL task, one of two data flow tasks must run, depending on the value of
the InStock variable.
You need to set the precedence constraints.
Which value for the evaluation operation should you use? (To answer, select the appropriate option for the evaluation
operation in the answer area.)

QUESTION 2
You are designing a SQL Server Integration Services (SSIS) package. The package moves order-related data to a
staging table named Order. Every night the staging data is truncated and then all the recent orders from the online
store
database are inserted into the staging
table.
Your package must meet the following requirements:
If the truncate operation fails, the package execution must stop and report an error.
If the Data Flow task that moves the data to the staging table fails, the entire refresh operation must be rolled back.
For auditing purposes, a log entry must be entered in a SQL log table after each execution of the Data Flow task.
The TransactionOption property for the package is set to Required.
You need to design the package to meet the requirements.
How should you design the control flow for the package? (To answer, drag the appropriate setting from the list of
settings to the correct location or locations in the answer area.)

QUESTION 3
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may
be correct for more than one question in the series. Each question is independent of the other questions in this series.
Information and details provided in a question apply only to that question.
You are developing a Microsoft SQL Server Integration Services (SSIS) package.
You are importing data from databases at retail stores into a central data warehouse. All stores use the same database
schema.
The query being executed against the retail stores is shown below:

examdemoprogram 70-767 exam questions-q3

The data source property named IsSorted is set to True. The output of the transform must be sorted.
You need to add a component to the data flow.
Which SSIS Toolbox item should you use?
A. CDC Control task
B. CDC Splitter
C. Union All
D. XML task
E. Fuzzy Grouping
F. Merge
G. Merge Join
Correct Answer: C

QUESTION 4
You develop a SQL Server Integration Services (SSIS) package that imports SQL Azure data into a data warehouse
every night.
The SQL Azure data contains many misspellings and variations of abbreviations. To import the data, a developer used
the Fuzzy Lookup transformation to choose the closest- matching string from a reference table of allowed values. The
number of rows in the reference table is very large.
If no acceptable match is found, the Fuzzy Lookup transformation passes a null value.
The current setting for the Fuzzy Lookup similarity threshold is 0.50.
Many values are incorrectly matched.
You need to ensure that more accurate matches are made by the Fuzzy Lookup transformation without degrading
performance.
What should you do?
A. Decrease the maximum number of matches per lookup.
B. Change the similarity threshold to 0.55.
C. Change the Exhaustive property to True.
D. Increase the maximum number of matches per lookup.
Correct Answer: B

QUESTION 5
You are designing the data warehouse to import data from three different environments. The sources for the data
warehouse will be loaded every hour.
Scenario A includes tables in a Microsoft Azure SQL Database:
1.
Millions of updates and inserts occur per hour
2.
A periodic query of the current state of rows that have changed is needed.
3.
The change detection method needs to be able to ignore changes to some columns in a table.
4.
The source database is a member of an AlwaysOn Availability group.
Scenario B includes tables with status update changes:
1.
Tracking the duration between workflow statuses.
2.
All transactions must be captured, including before/after values for UPDATE statements.
3.
To minimize impact to performance, the change strategy adopted should be asynchronous.
Scenario C includes an external source database:
1.
Updates and inserts occur regularly.
2.
No changes to the database should require code changes to any reports or applications.
3.
Columns are added and dropped to tables in the database periodically. These schema changes should not require any
interruption or reconfiguration of the change detection method chose.
4.
Data is frequently queried as the entire row appeared at a past point in time.
All tables have primary keys.
You need to load each data source. You must minimize complexity, disk storage, and disruption to the data sources and
the existing data warehouse.
Which change detection method should you use for each scenario? To answer, drag the appropriate loading methods to
the correct scenarios. Each source may be used once, more than once, or not at all. You may need to drag the split bar
between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Box A: System-Versioned Temporal Table
System-versioned temporal tables are designed to allow users to transparently keep the full history of changes for later
analysis, separately from the current data, with the minimal impact on the main OLTP workload.
Box B: Change Tracking
Box C: Change Data Capture
Change data capture supports tracking of historical data, while that is not supported by change tracking.

while
others might not have a correct solution.
After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not

development efforts and maintenance:

examdemoprogram 70-767 exam questions-q6

 Solution: You add the control flow to a control flow package part. You add an instance of the control flow package part
to each data warehouse load package. Does the solution meet the goal?
A. Yes
B. No
Correct Answer: A
A package consists of a control flow and, optionally, one or more data flows. You create the control flow in a package by
using the Control Flow tab in SSIS Designer. References: https://docs.microsoft.com/en-us/sql/integrationservices/control-flow/control-flow

QUESTION 7
After you answer a question in this section, you will NOT be able to return to it. As a result these questions will not
appear in the review screen.
You are configuring a Microsoft SQL server named dw1for a new data warehouse. The server contains eight drives and
eight processor cores. Each drive uses a separate physical disk.
You need to configure storage for the tempdb database. The solution must minimize the amount of time it takes to

The fact table must meet the following requirements:
Correct Answer: C

 QUESTION 13
You are developing a Microsoft SQL Server Integration Services (SSIS) package to incrementally load new and
changed records from a data source.
The SSIS package must load new records into Table1 and updated records into Table1_Updates. After loading records,
the package must call a Transact-SQL statement to process updated rows according to existing business logic.

Correct Answer:

examdemoprogram 70-767 exam questions-q13-2

Step 1: CDC Control Task Get Processing Range
Step 2: Mark Processed Range
Step 3: Data Flow
The Data Flow task encapsulates the data flow engine that moves data between sources and destinations, and lets the
user transform, clean, and modify data as it is moved. Addition of a Data Flow task to a package control flow makes it
possible for the package to extract, transform, and load data.
Step 4: CDC Source
The CDC source reads a range of change data from SQL Server 2017 change tables and delivers the changes
downstream to other SSIS component.
Step 5: CDC Splitter
The CDC splitter splits a single flow of change rows from a CDC source data flow into different data flows for Insert,
Update and Delete operations.
