Q16. - (Topic 2)
You need to configure per-user security authentication for reporting against the Sales cube.
What should you do? (Each correct answer presents part of the complete solution. Choose all that apply.)
A. Create Service Principal Names (SPNs).
B. Configure account delegation.
C. Enable forms-based authentication.
D. Enable mixed-mode authentication.
Answer: A,D
Explanation: * From scenario:
/ Administrative staff from around the world will produce sales reports with Microsoft Excel
2010 based on the Sales cube.
/ Security requirements
When possible, the system must use Windows authentication for all database connections.
The system must prevent users from querying data from outside of their region.
The system must allow certain users to query data from multiple regions.
A: To use Kerberos authentication with SQL Server requires both the following conditions to be true: The client and server computers must be part of the same Windows domain, or in trusted domains. A Service Principal Name (SPN) must be registered with Active Directory, which assumes the role of the Key Distribution Center in a Windows domain. The SPN, after it is registered, maps to the Windows account that started the SQL Server instance service. If the SPN registration has not been performed or fails, the Windows security layer cannot determine the account associated with the SPN, and Kerberos authentication will not be used.
D: For windows authentication we need to enable mixed-mode authentication

Q20. - (Topic 3)
You need to configure the Scenario attribute to ensure that business users appropriately query the Sales Plan measure.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
A. Set the AttributeHierarchyVisible property to False.
B. Set the IsAggregatable property to False.
C. Set the Usage property to Parent.
D. set the DefaultMember property to the Forecast member.
E. Set the AttributeHierarchyEnabled property to False.
F. Set the RootMemberIf property to ParentIsMissing.
Answer: C,D
Explanation:
The Sales measure group is based on the FactSales table. The Sales Plan measure group is based on the FactSalesPlan table. The Sales Plan measure group has been configured with a multidimensional OLAP (MOLAP) writeback partition. Both measure groups use MOLAP partitions, and aggregation designs are assigned to all partitions.
Topic 4, Contoso, Ltd Case A
General Background You are the SQL Server Administrator for Contoso, Ltd. You have been tasked with upgrading all existing SQL Server instances to SQL Server 2012.
Technical Background The corporate environment includes an Active Directory Domain Services (AD DS) domain named contoso.com. The forest and domain levels are set to Windows Server 2008. All default containers are used for computer and user accounts. All servers run Windows Server 2008 R2 Service Pack 1 (SP1). All client computers run Windows 7 Professional
SP1. All servers and client computers are members of the contoso.com domain.
The current SQL Server environment consists of a single instance failover cluster of SQL
Server 2008 R2 Analysis Services (SSAS). The virtual server name of the cluster is
SSASCluster. The cluster includes two nodes: Node1 and Node2. Node1 is currently the
active node. In anticipation of the upgrade, the prerequisites and shared components have
been upgraded on both nodes of the cluster, and each node was rebooted during a weekly
maintenance window.
A single-server deployment of SQL Server 2008 R2 Reporting Services (SSRS) in native
mode is installed on a server named SSRS01. The Reporting Server service is configured
to use a domain service account. SSRS01 hosts reports that access the SSAS databases
for sales data as well as modeling data for the Research team. SSRS01 contains 94
reports used by the organization. These reports are generated continually during business
hours. Users report that report subscriptions on SSRS01 are not being delivered. You run
the reports on demand from Report Manager and find that the reports render as expected.
A new server named SSRS02 has been joined to the domain, SSRS02 will host a single-
server deployment of SSRS so that snapshots of critical reports are accessible during the
upgrade.
The server configuration is shown in the exhibit. (Click the Exhibit button.)
The production system includes three SSAS databases that are described in the following table.
All SSAS databases are backed up once a day, and backups are stored offsite.
Business Requirements After the upgrade users must be able to perform the following tasks: . Ad-hoc analysis of data in the SSAS databases by using the Microsoft Excel PivotTable client. . Daily operational analysis by executing a custom application that uses ADOMD.NET and existing Multidimensional Expressions (MDX) queries.
...
The detailed data must be stored in the model.
Technical Requirements You need to minimize downtime during the SSASCluster upgrade. The upgrade must minimize user intervention and administrative effort.
The upgrade to SQL Server 2012 must maximize the use of all existing servers, require the least amount of administrative effort, and ensure that the SSAS databases are operational as soon as possible.
You must implement the highest level of domain security for client computers connecting to SSRS01. The SSRS instance on SSRS01 must use Kerberos delegation to connect to the SSAS databases. Email notification for SSRS01 has not been previously configured. Email notification must be configured to use the SMTP server SMTP01 with a From address of reports@contoso.com. Report distribution must be secured by using SSL and must be limited to the contoso.com domain.
You have the following requirements for SSRS02:
Replicate the SSRS01 configuration.
Ensure that all current reports are available on SSRS02.
Minimize the performance impact on SSR501.
In preparation for the upgrade, the SSRS-related components have been installed on the new SSRS02 server by using the Reporting Services file-only installation mode. The Reporting Services databases have been restored from SSRS01 and configured appropriately.
You must design a strategy to recover the SSRS instance on SSRS01 in the event of a system failure. The strategy must ensure that SSRS can be recovered in the minimal amount of time and that reports are available as soon as possible. Only functional components must be recovered.
SSRS02 is the recovery server and is running the same version of SSRS as SSRS01. A full backup of the SSRS databases on SSRS01 is performed nightly. The report server configuration files, custom assemblies, and extensions on SSRS02 are manually synchronized with SSRS01. Prior to implementing the upgrade to SQL Server 2012, you must back up all existing SSAS databases.
Databases on SSRS01 is performed nightly. The report server configuration files, custom assemblies, and extensions on SSRS02 are manually synchronized with SSRS01.
Prior to implementing the upgrade to SQL Server 2012, you must back up all existing SSAS databases. The backup must include only the partitioning, metadata, and aggregations to minimize the processing time required when restoring the databases. You must minimize processing time and the amount of disk space used by the backups.
Before upgrading SSAS on the SSASCluster, all existing databases must be moved to a temporary staging server named SSAS01 that hosts a default instance of SQL Server 2012 Analysis Services. This server will be used for testing client applications connecting to SSAS 2012, and as a disaster recovery platform during the upgrade. You must move the databases by using the least amount of administrative effort and minimize downtime. All SSAS databases other than the Research database must be converted to tabular BI Semantic Models (BISMs) as part of the upgrade to SSAS 2012. The Research team must have access to the Research database for modeling throughout the upgrade. To facilitate this, you detach the Research database and attach it to SSAS01.
While testing the Research database on SSAS01, you increase the compatibility level to 1100. You then discover a compatibility issue with the application. You must roll back the compatibility level of the database to 1050 and retest.
After completing the upgrade, you must do the following:
1.
Design a role and assign an MDX expression to the Allowed member set property of the Customer dimension to allow sales representatives to browse only members of the Customer dimension that are located in their sales regions. Use the sales representatives' logins and minimize impact on performance.
2.
Deploy a data model to allow the ad-hoc analysis of data. The data model must be cached and source data from an OData feed.
