Q122. DRAG DROP - (Topic 9)
You are the database administrator of a SQL Server 2012 data warehouse implemented as a single database on a production server. The database is constantly updated by using SQL Server Integration Services (SSIS) packages and SQL Server Analysis Services (SSAS) cube writeback operations.
The database uses the full recovery model. A backup strategy has been implemented to minimize data loss in the event of hardware failure.
SQL Server Agent jobs have been configured to implement the following backup operations:
A full database backup every day at 12:00 A.M.
Differential database backups every day at 6:00 A.M., 12:00 P.M., and 6:00 P.M.
Transaction log backups every hour on the hour.
...
At 2:38 P.M. a SSIS package corrupts the data in a fact table. The corruption cannot be undone. You are notified at 3:15 P.M. You immediately take the database offline to prevent further data access and modification.
You need to restore the data warehouse and minimize downtime and data loss.
Which four 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.

Q123. - (Topic 10)
You are working with multiple tabular models deployed on a single SQL Server Analysis Services (SSAS) instance.
You need to ascertain the memory consumed by each object in the SSAS instance.
What should you do?
A. Use the $System.discover_object_memory_usage dynamic management view.
B. Use the Usage Based Optimization wizard to design appropriate aggregations.
C. Use SQL Server Profiler to review session events for active sessions.
D. Use the Performance Counter group named Processing.
Answer: A
Q124. HOTSPOT - (Topic 9)
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.

Q126. DRAG DROP - (Topic 10)
You are developing a SQL Server Analysis Services (SAS) multidimensional project that is configured to source data from a SQL Azure database.
You plan to use multiple servers to process different partitions simultaneously. You create and configure a new data source.
You need to create a new partition and configure SQL Server Analysis Services (SSAS) to use a remote server to process data contained within the partition.
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.)

A. Use a required package parameter.
B. Use a required project parameter.
C. Use a package configuration.
D. Use a global variable.
Answer: B
Topic 6, WingTip Toys
General Background
You are a data architect for WingTip Toys. The company uses SQL Server 2012 Enterprise
edition. SQL Server Analysis Services (SSAS) and SQL Server Reporting Services (SSRS)
are installed on separate servers.
Data Warehouse
The company's data warehouse initially contained less than 100 MB and 100 million rows
of data from only one data source. It now contains more than 10 TB and 10 billion rows of
data, in 25 tables, from 12 data sources.
The largest table in the data warehouse, the factOrders table, contains 5 TB of data. The
factOrders table contains three date keys: OrderDateKey InvoiceDateKey, and
ShipDateKey. The data warehouse server has 1 TB of RAM. Memory usage is currently at
20 percent.
One billion rows of data are added to the data warehouse each month. New data is copied
each night from the data sources into SQL Server staging tables, and existing records are
not updated. The largest data set is order information, which is loaded in parallel into
multiple staging tables, one for each data source. All the staging tables have the same
structure and belong to the same filegroup as the factOrders table.
The dimCustomers table stores customer information that may change over time.
Data Models
You are developing three SSAS databases, as described in the following table.
Reporting
Business users frequently generate reports in Microsoft Excel by using PowerPivot. The
PowerPivot Management Dashboard does not currently display any usage data.
Several SSRS reports exist that use the data warehouse as a source. The data warehouse
queries are aggregate queries that use the factOrders table and one or more dimension
tables. All SSRS data sources use Integrated Windows authentication.
SSRS displays a security access error message when managers run SSRS reports based
on the Operations database.
Reporting performance has become unacceptably slow.
Business Requirements
Improve the query speed of the SSRS reports.
Allow business users to create reports by using PowerPivot and Power View.
Ensure that all users other than business users can view metadata for the Customers
dimension. Ensure that business users cannot view metadata for the Customers
dimension.
Technical Requirements
Modify the tables in the data warehouse to minimize aggregate query processing time.
Minimize disk storage in the data warehouse.
Ensure that all multidimensional models process data as quickly as possible.
Create a fact table named factCustomerContact in the data warehouse to store the contact
date, customer key, and communication type for each instance of customer contact.
Store the history of customer information changes in the dimCustomers table.
Move data from the staging tables into the factOrders table as quickly as possible. When
creating dimensions for the date keys in the factOrders table, minimize storage space
requirements and optimize the cube processing time.
Ensure that queries against the Sales database return the most current data in the data
warehouse.
Ensure that the SSAS model of the Finance database does not page to disk or return a
memory error as the size of the database grows.
Create an SSAS monitoring solution that tracks the following data: Queries answered per second Queries from cache direct per second Queries from file per second.
...
Q128. - (Topic 9)
An existing cube dimension that has 30 attribute hierarchies is performing very poorly. You have the following requirements:
. Implement drill-down browsing. . Reduce the number of attribute hierarchies but ensure that the information contained within them is available to users on demand. . Optimize performance.
You need to redesign the cube dimension to meet the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. set the AggregateFunction property to Sum on all measures. Use the SCOPE statement in a Multidimensional Expressions (MDX) calculation to tune the aggregation types.
B. Set the AttributeHierarchyOptimizedState property to FullyOptimized on the attribute hierarchies.
C. Create user-defined hierarchies. For the attributes sourced by the levels of the user-defined hierarchies, set the RelationshipType property to Rigid. Run incremental processing.
D. Remove as many attribute hierarchies as possible from the dimension. Reintroduce the information in the attribute hierarchies as properties. Implement natural hierarchies and set the AttributeHierarchyVisible property to False for attributes used as levels in the natural
hierarchies.
Answer: D
Q129. - (Topic 5)
You need to scale out SSAS.
What should you do?
A. Back up the cube on ServerB and restore it on ServerC each day.
B. Create an empty cube on ServerC and link to the objects in the cube on ServerB.
C. Process the cube on both ServerB and ServerC each day.
D. Synchronize the cube from ServerB to ServerC each day.
Answer: D
