QUESTION 1
Hotspot Questions
A SQL Server Analysis Services (SSAS) cube contains billions of rows of data and is rapidly increasing in size.
The cube consists of a single measure group and a single partition.
The cube is currently processed by using the Process Full process option.
You have the following requirements to reduce the cube processing time:
– 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.
Answer:
Explanation:
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 2
Drag and Drop Questions
You administer a SQL Server Analysis Services (SSAS) instance.
You need to capture a continuous log of detailed event and subevent durations and custom trace events from queries executed in the SSAS instance.
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:
mdx script “discover_traces”
Box 1: Write an XMLA script to log the extended events of the trace.
Box 2: Launch SQL Server Management Studio and connect to the instance.
Box 3: Execute the script.
Note:
– Auditing an instance of SQL Server or a SQL Server database involves tracking and logging events that occur on the system. The SQL Server Audit object collects a single instance of server-or database-level actions and groups of actions to monitor. The audit is at the SQL Server instance level.
You can have multiple audits per SQL Server instance. The Server Audit Specification object belongs to an audit. You can create one server audit specification per audit, because both are created at the SQL Server instance scope.
– Trace events can be started and captured using SQL Server Profiler, , or can be started from an XMLA command as SQL Server Extended Events and later analyzed.
– Extended Event tracing is enabled using a similar XMLA create object script.

QUESTION 3
Drag and Drop Questions
You plan to deploy a SQL Server Integration Services (SSIS) project by using the project deployment model.
You need to monitor control flow tasks to determine whether any of them are running longer than usual.
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:
– execution_component_phases
Displays the time spent by a data flow component in each execution phase.
– The following example uses the catalog.execution_component_phases view to find the total amount of time that a specific package has spent executing in all phases (active_time), and the total elapsed time for the package (total_time).
use SSISDB
select package_name, task_name, subcomponent_name, execution_path, SUM(DATEDIFF(ms,start_time,end_time)) as active_time, DATEDIFF(ms,min(start_time), max(end_time)) as total_time from catalog.execution_component_phases
where execution_id = 1841
group by package_name, task_name, subcomponent_name, execution_path order by package_name, task_name, subcomponent_name, execution_path
– catalog.executables
This view displays a row for each executable in the specified execution.
An executable is a task or container that you add to the control flow of a package.
– (incorrect) catalog.executions (SSISDB Database)
Displays the instances of package execution in the Integration Services catalog. Packages that are executed with the Execute Package task run in the same instance of execution as the parent package.
This view displays a row for each instance of execution in the catalog.
– (incorrect) catalog.operation_messages
Displays messages that are logged during operations in the Integration Services catalog.
This view displays a row for each message that is logged during an operation in the catalog.
The message can be generated by the server, by the package execution process, or by the execution engine.

The fact table supporting the measure group is loaded with new data throughout the day.
You have the following requirements:
– Ensure that the cube displays current data as quickly as possible.
– Maximize availability of the cube.
– Maximize query performance for all aggregation levels.
You need to choose a partitioning strategy that meets the requirements.
Which partitioning strategy should you choose? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Create one partition for the current day that uses multidimensional OLAP (MOLAP) with
proactive caching as a storage mode.
B. Create one partition for the current month that uses hybrid OLAP (HOLAP) as a storage
mode.
C. Create one partition for the current day that uses relational OLAP (ROLAP) as a storage
mode.
D. Create one partition for the current day that uses multidimensional OLAP (MOLAP) as a
storage mode. Process the partition each night.
Answer: A

You are designing a SQL Server Reporting Services (SSRS) solution.
A report project must access multiple SQL Azure databases.
Each database is on a different host.
The databases have identical schema and security configurations.
You have the following requirements:
– The report must support subscriptions.
– Users must be able to select the host when running the report.
What should you do? To answer, drag the appropriate phrase or phrases from the list to the correct location or locations in the answer area. (Answer choices may be used once, more than once, or not all.)
Answer:
Explanation:
Note:
– To include data in a report, you must first create data connections, also known as data sources, and then create datasets.
– A data connection includes the data source type, connection information, and the type of credentials to use. There are two types of data sources: embedded and shared.
An embedded data source is defined in the report and used only by that report (fits this scenario).
A shared data source is defined independently from a report and can be used by multiple reports.
– Built-in data extensions include the following data connection types:
Microsoft SQL Server
Microsoft SQL Server Analysis Services
Microsoft SharePoint List
Windows Azure SQL Database
Etc.
– Expression-based connection strings are evaluated at run time.
For example, you can specify the data source as a parameter, include the parameter reference in the connection string, and allow the user to choose a data source for the report.
– Credentials You provide the credentials that are needed to access the data. The data source owner must have granted you the appropriate permissions to access both the data source and the specific data on the data source.

An existing report aggregates data from a SQL Server database in a chart.
You need to use the chart in a new report and ensure that other users can use the chart in their reports.
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:
Note:
– In Report Designer, after you create tables, charts, and other report items in a project, you can publish them as report parts to a report server or SharePoint site integrated with a report server so that you and others can reuse them in other reports.
– By using Report Builder, you can customize and update reports that were created in SQL Server Data Tools (SSDT) Report Designer.
– In Report Builder, IT pros and power users can create powerful operational reports, and reusable report parts and shared datasets.
