Designing Business Intelligence Solutions with Microsoft SQL Server 2012

Question No: 101 – (Topic 7)

You are redesigning a SQL Server Analysis Services (SSAS) database that contains a cube named Sales. Before the initial deployment of the cube, partition design was

optimized for processing time. The cube currently includes five partitions named FactSalesl through FactSales5. Each partition contains from 1 million to 2 million rows.

The FactSales5 partition contains the current year#39;s information. The other partitions contain information from prior years; one year per partition. Currently, no aggregations are defined on the partitions.

You remove fact rows that are more than five years old from the fact table in the data source and configure query logs on the SSAS server.

Several queries and reports are running very slowly.

You need to optimize the partition structure and design aggregations to improve query performance and minimize administrative overhead.

What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

  1. Use the Usage-Based Optimization Wizard to create aggregations for the current partitions.

  2. Use the Aggregation Design Wizard to create aggregations for the current partitions.

  3. Combine all the partitions into a single partition. Use the Usage-Based Optimization Wizard to create aggregations.

  4. Combine all the partitions into a single partition. Use the Aggregation Design Wizard to create aggregations.

Answer: A

Question No: 103 – (Topic 7)

You are designing an extract, transform, load (ETL) process for loading data from a SQL Server database into a large fact table in a data warehouse each day with the prior day#39;s sales data.

The ETL process for the fact table must meet the following requirements:

->Load new data in the shortest possible time.

->Remove data that is more than 36 months old.

->Ensure that data loads correctly.

->Minimize record locking.

->Minimize impact on the transaction log.

You need to design an ETL process that meets the requirements.

What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

  1. Partition the destination fact table by date. Insert new data directly into the fact table and delete old data directly from the fact table.

  2. Partition the destination fact table by date. Use partition switching and staging tables both to remove old data and to load new data.

  3. Partition the destination fact table by customer. Use partition switching both to remove old data and to load new data into each partition.

  4. Partition the destination fact table by date. Use partition switching and a staging table to remove old data. Insert new data directly into the fact table.

Answer: B

Question No: 104 HOTSPOT – (Topic 7)

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.

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.

Question No: 105 – (Topic 7)

You have a SQL Server Reporting Services (SSRS) 2008 instance integrated with an Internet-facing Microsoft SharePoint 2010 farm. PerformancePoint Services and Excel Services are installed and configured.

You need to upgrade to SSRS 2012 with the minimum downtime and hardware requirements.

What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

  1. Migrate SSRS content to a separate instance of SSRS 2012 on the same server.

  2. Perform an in-place upgrade of the SSRS environment.

  3. Migrate SSRS content to new servers that run SSRS 2012.

  4. Install SSRS 2012 on a new SharePoint farm and migrate content to the new farm.

Answer: C

Question No: 106 DRAG DROP – (Topic 7)

You are the administrator of a SQL Server Integration Services (SSIS) catalog. You have access to the original password that was used to create the SSIS catalog.

A full database backup of the SSISDB database on the production server is made each day. The server used for disaster recovery has an operational SSIS catalog.

The production server that hosts the SSISDB database fails.

Sensitive data that is encrypted in the SSISDB database must not be lost.

You need to restore the production SSIS catalog to the disaster recovery server.

Which three steps 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.

Question No: 107 DRAG DROP – (Topic 7)

Your network contains a development environment, a staging environment, and a production environment.

You have a SQL Server Integration Services (SSIS) project. All of the packages in the project load data from files in a shared network folder. The packages use indirect XML configurations to set the location of the network folder.

The project is deployed to the three environments. Each environment has a different set of source files and a different network folder for the source files.

Currently, if an environment variable is missing, the package will use the network folder specified in the package, not the folder specified in the XML configuration file.

You need to ensure that each time a package is executed, the network folder location specified in the package is NOT used.

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.

Question No: 108 – (Topic 7)

You are designing a partitioning strategy for a large fact table in a Manufacturing data warehouse.

Tens of millions of new inventory fact records are loaded into the data warehouse weekly, outside of business hours. Most queries against the database are generated by reports and by cube processing. Data is frequently queried at the day level and occasionally at the month level.

  1. Partition the inventory fact table by month, and compress each partition.

  2. Partition the inventory fact table by day, and compress each partition.

  3. Partition the inventory fact table by year.

  4. Partition the inventory fact table by week.

Answer: B

->Partition the measure group by month.

->Create a staging table that contains only data which is more recent than the last time the cube was processed.

->Do not include data updates or deletions in the staging table.

->Insert records from the staging table into the appropriate partition.

You need to change the process option to meet the requirements.

Which process option should you choose?

To answer, select the appropriate option from the drop-down list in the dialog box.

Note: ProcessAdd

ProcessAdd applies only to dimensions and partitions.

ProcessAdd is a new processing option for dimensions that did not exist in Analysis Services 2000. It essentially optimizes ProcessUpdate for the scenario where only new members are added. ProcessAdd never deletes or updates existing members. It only adds new members. The user can restrict the dimension table so that ProcessAdd reads only the new rows.

ProcessAdd for partitions is the equivalent of incremental partition processing in Analysis Services 2000. The user typically specifies an alternate fact table or a filter condition pointing to the new rows. ProcessAdd internally creates a temporary partition, processes it with the specified fact data, and merges it into the target partition.

Question No: 110 – (Topic 7)
