    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.)

    Dumps4Cert 2018 PDF and VCE

    The production system includes three SSAS databases that are described in the following table.

    Dumps4Cert 2018 PDF and VCE

    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#39; 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.

      Question No: 35 – (Topic 4)

      You need to implement the security requirement for the sales representatives. Which MDX expression should you use?

Question No: 36 – (Topic 4)

You need to perform the pre-upgrade database backup operation by using SQL Server Management Studio (SSMS).

How should you configure the backup options?

  1. Select the Apply compression check box. Select the Encrypt backup file check box and supply a password.

  2. Clear the Apply compression check box. Select the Encrypt backup file check box and supply a password.

  3. Clear the Apply compression check box. Clear the Encrypt backup file check box.

  4. Select the Apply compression check box. Clear the Encrypt backup file check box.

Answer: D

Question No: 37 – (Topic 4)

You need to re-establish subscriptions on SSRS01. What should you do?

  1. Manually failover the active node.

  2. Install prerequisites and upgrade shared components on Node1 and Node2.

  3. Generate a SQL Server 2012 configuration file by running the SQL Server Setup executable.

  4. Upgrade Node1 by using the SQL Server 2012 Upgrade wizard.

Answer: A Explanation:

SSRS reports are scheduled by SQL server Agent jobs. Start the SQL Server Agent on SSRS01.

Question No: 38 – (Topic 4)

You need to configure security for the SSRS instance on SSRS01 to connect to SSAS and minimize downtime.

What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

  1. Register a service principal name for the Report Server service.

  2. Register a service principal name for the Analysis Services service.

  3. Restart the IIS service.

  4. Configure SSRS01 to use the Negotiate authentication type.

  5. Configure SSRS01 to use the Custom authentication type.

Answer: A,D

Explanation: A (not B): If you are deploying Reporting Services in a network that uses the Kerberos protocol for mutual authentication, you must create a Service Principal Name (SPN) for the Report Server service if you configure it to run as a domain user account.

D (not E):

* See step 6 below.

To register an SPN for a Report Server service running as a domain user

->Install Reporting Services and configure the Report Server service to run as a domain user account. Note that users will not be able to connect to the report server until you complete the following steps.

->Log on to the domain controller as domain administrator.

->Open a Command Prompt window.

->Copy the following command, replacing placeholder values with actual values that

are valid for your network:

->Setspn -a http/lt;computer-namegt;.lt;domain-namegt;:lt;portgt;lt;domain-user-accountgt;

->Run the command.

->Open the RsReportServer.config file and locate the lt;AuthenticationTypesgt; section. Add lt;RSWindowsNegotiate/gt; as the first entry in this section to enable NTLM.

  • RSWindowsNegotiate. If you initially set the Windows service account for the report server to NetworkService or LocalSystem in Reporting Services Configuration Manager, RSWindowsNegotiate is added to the RSReportServer.config file as the default setting. With this setting, the report server can accept requests from client applications requesting Kerberos or NTLM authentication. If Kerberos is requested and the authentication fails, the report server switches to NTLM authentication and prompts the user for credentials unless the network is configured to manage authentication transparently.

    Using RSWindowsNegotiate is your best option because it provides the greatest flexibility for multiple clients in an intranet environment.

    Not C: IIS is not mention in this scenario. Note:

  • From scenario:

    / 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.

    Reference: Register a Service Principal Name (SPN) for a Report Server

    Question No: 39 – (Topic 4)

    You need to roll back the compatibility level of the Research database. What should you do?

    1. Restore a backup of the previous version of the database.

    2. Use an ALTER DATABASE statement to set the compatibility option.

    3. Change the CompatibilityLevel property in the XMLA script, and then execute the script.

    4. In SQL Server Management Studio (SSMS), change the compatibility level in the database properties.

    Answer: A

    Question No: 40 – (Topic 4)

    You need to develop a BISM that meets the business requirements for ad-hoc and daily operational analysis. You must minimize development effort.

    Which development approach and mode should you use?

    1. Develop a tabular project and configure the model with the DirectQuery mode setting on and the project query mode set to DirectQuery.

    2. Develop a tabular project and configure the model with the DirectQuery mode setting on and the project query mode set to In-Memory with DirectQuery.

    3. Develop a multidimensional project and configure the model with the DirectQuery mode setting off.

    4. Develop a multidimensional project and configure the cube to use hybrid OLAP (HOLAP) storage mode.

    Answer: C Explanation:

    / 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 (which uses MDX).

    / Daily operational analysis by executing a custom application that uses ADOMD.NET and existing Multidimensional Expressions (MDX) queries.

    / 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.

    We cannot use DirectQuery mode so C is the only answer that will provide the required caching.

    When a model is in DirectQuery mode, it can only be queried by using DAX. You cannot use MDX to create queries. This means that you cannot use the Excel Pivot Client, because Excel uses MDX.
