QUESTION 18
Drag and Drop Questions
You are creating a SQL Server Integration Services (SSIS) package to populate a fact table from a source table. The fact table and source table are located in a SQL Azure database. The source table has a price field and a tax field. The OLE DB source uses the data access mode of Table. You have the following requirements:
– The fact table must populate a column named TotalCost that computes the sum of the price and tax columns.
– Before the sum is calculated, any records that have a price of zero must be discarded.
You need to create the SSIS package in SQL Server Data Tools. In what sequence should you order four of the listed components for the data flow task? (To answer, move the appropriate components from the list of components to the answer area and arrange them in the correct order.)

QUESTION 19
Drag and Drop Questions
You are designing a SQL Server Integration Services (SSIS) package to execute 12 Transact-SQL (T-SQL) statements on a SQL Azure database. The T-SQL statements may be executed in any order. The T-SQL statements have unpredictable execution times. You have the following requirements:
– The package must maximize parallel processing of the T-SQL statements.
– After all the T-SQL statements have completed, a Send Mail task must notify administrators.
You need to design the SSIS package. 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.)
Answer:
Explanation:
Box 1: Add a Sequence container to the control flow.
Box 2: Add 12 Execute SQL tasks to the Sequence container and configure the tasks.
Box 3: Add a Send mail task to the control flow. Add a precedence constraint for Completion to the to the Sequence container and link it to the Send Mail task.
Note:
The Sequence container defines a control flow that is a subset of the package control flow. Sequence containers group the package into multiple separate control flows, each containing one or more tasks and containers that run within the overall package control flow.
Reference: Sequence Container

You are configuring the partition storage settings for a SQL Server Analysis Services (SSAS) cube. The partition storage must meet the following requirements:
– Optimize the storage of source data and aggregations in the cube.
– Use proactive caching.
– Drop cached data that is more than 30 minutes old.
– Update the cache when data changes, with a silence interval of 10 seconds.
You need to select the partition storage setting. Which setting should you select? To answer, select the appropriate setting in the answer area.
Answer:
Explanation:
Low Latency MOLAP. Detail data and aggregations are stored in multidimensional format. The server listens for notifications of changes to the data and switches to real-time ROLAP while MOLAP objects are reprocessed in a cache. A silence interval of at least 10 seconds is required before updating the cache. There is an override interval of 10 minutes if the silence interval is not attained. Processing occurs automatically as data changes with a target latency of 30 minutes after the first change. This setting would typically be used for a data source with frequent updates when query performance is somewhat more important than always providing the most current data. This setting automatically processes MOLAP objects whenever required after the latency interval. Performance is slower while the MOLAP objects are being reprocessed.
