   Currently, all SAP applications are in the litware.com domain.

   Problem Statements

   The current version of SAP ECC has a transaction that, when run in batches overnight, takes eight hours to complete. You confirm that upgrading to SAP Business Suite on HANA will improve performance because of code changes and the SAP HANA database platform.

   Litware is dissatisfied with the performance of its current hosted infrastructure vendor. Litware experienced several hardware failures and the vendor struggled to adequately support its 24/7 business operations.

   Requirements

   Business Goals

   Litware identifies the following business goals:

   – Increase the performance of SAP ECC applications by moving to SAP HANA. All other SAP databases will remain on SQL Server.
   – Move away from the current infrastructure vendor to increase the stability and availability of the SAP services.
   – Use the new Environment, Health and Safety (EH&S) in Recipe Management function.
   – Ensure that any migration activities can be completed within a 48-hour period during a weekend.

   Planned Changes

   Litware identifies the following planned changes:

   – Migrate SAP to Azure.
   – Upgrade and migrate SAP ECC to SAP Business Suite on HANA Enhancement Pack 8.

   Technical Requirements

   Litware identifies the following technical requirements:

   – Implement automated backups.
   – Support load testing during the migration.
   – Identify opportunities to reduce costs during the migration.
   – Continue to use the litware.com domain for all SAP landscapes.
   – Ensure that all SAP applications and databases are highly available.
   – Establish an automated monitoring solution to avoid unplanned outages.
   – Remove all SAP components from the on-premises network once the migration is complete.
   – Minimize the purchase of additional SAP licenses. SAP HANA licenses were already purchased.
   – Ensure that SAP can provide technical support for all the SAP landscapes deployed to Azure.

   1. What should you use to perform load testing as part of the migration plan?

      • JMeter
      • SAP LoadRunner by Micro Focus
      • Azure Application Insights
      • Azure Monitor
      Explanation:
      Scenario: Upgrade and migrate SAP ECC to SAP Business Suite on HANA Enhancement Pack 8.

      With the SAP LoadRunner application by Micro Focus, you can accelerate testing and development, reduce slowdowns and expenses, and gain a better understanding of performance issues. Validate software performance, virtualize your network, simulate workloads, benchmark production system performance, and optimize your deployment of SAP HANA software

3. Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

   After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

   You deploy SAP HANA on Azure (Large Instances).

   You need to back up the SAP HANA database to Azure.

   Solution: You use a third-party tool that uses backint to back up the SAP HANA database to Azure storage.

   Does this meet the goal?

   • Yes
   • No

4. DRAG DROP

   You have an SAP environment on Azure.

   You use Azure Site Recovery to protect an SAP production landscape.

   You need to validate whether you can recover the landscape in the event of a failure. The solution must minimize the impact on the landscape.

   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.

   

   

   Explanation:

   Step 1: Create a virtual network…
   We recommended that for test failover, you choose a network that’s isolated from the production recovery site network specific in the Compute and Network settings for each VM. By default, when you create an Azure virtual network, it is isolated from other networks. The test network should mimic your production network:

   The test network should have same number of subnets as your production network. Subnets should have the same names.
   The test network should use the same IP address range.

   Step 2: Add a public IP address…
   Because Site Recovery does not replicate the cloud witness, we recommend that you deploy the cloud witness in the disaster recovery region.

   Step 3: Shut down production virtual machines
   Make sure that the primary VM is shut down when you run the test failover. Otherwise there will be two VMs with the same identity, running in the same network at the same time. This can lead to unexpected consequences.

   Step 4: Select Test failover from the Recovery Plans blade

5. You recently migrated an SAP HANA environment to Azure.

   You plan to back up SAP HANA databases to disk on the virtual machines, and then move the backup files to Azure Blob storage for retention.

   Which command should you run to move the backups to the Blob storage?

   • robocopy
   • backint
   • azcopy
   • scp
   Explanation:

   To store directories and files on Azure storage, one could use CLI or PowerShell. There is also a ready-to-use utility, AzCopy, for copying data to Azure storage.

6. Case Study This is a case study. Case studies are not timed separately. You can use as much exam time as you would like to complete each case. However, there may be additional case studies and sections on this exam. You must manage your time to ensure that you are able to complete all questions included on this exam in the time provided.

   Problem Statements

   Contoso identifies the following issues in its current environment:

   – The SAP HANA environment lacks adequate resources.
   – The Windows servers are nearing the end of support.
   – The datacenters are at maximum capacity.

   Requirements

   Planned Changes

   Contoso identifies the following planned changes:

   – Deploy Azure Virtual WAN.
   – Migrate the application servers to Windows Server 2016.
   – Deploy ExpressRoute connections to all of the offices and manufacturing facilities.
   – Deploy SAP landscapes to Azure for development, quality assurance, and production.

   All resources for the production landscape will be in a resource group named SAPProduction.

   Business goals

   Contoso identifies the following business goals:

   – Minimize costs whenever possible.
   – Migrate SAP to Azure without causing downtime.
   – Ensure that all SAP deployments to Azure are supported by SAP.
   – Ensure that all the production databases can withstand the failure of an Azure region.
   – Ensure that all the production application servers can restore daily backups from the last 21 days.

   Technical Requirements

   Contoso identifies the following technical requirements:

   – Inspect all web queries.
   – Deploy an SAP HANA cluster to two datacenters.
   – Minimize the bandwidth used for database synchronization.
   – Use Active Directory accounts to administer Azure resources.
   – Ensure that each production application server has four 1-TB data disks.
   – Ensure that an application server can be restored from a backup created during the last five days within 15 minutes.
   – Implement an approval process to ensure that an SAP administrator is notified before another administrator attempts to make changes to the Azure virtual machines that host SAP.

   It is estimated that during the migration, the bandwidth required between Azure and the New York office will be 1 Gbps. After the migration, a traffic burst of up to 3 Gbps will occur.

   Proposed Backup Policy

   An Azure administrator proposes the backup policy shown in the following exhibit.

   

   Azure Resource Manager Template

   An Azure administrator provides you with the Azure Resource Manager template that will be used to provision the production application servers.

   

   

   1. Once the migration completes, to which size should you set the ExpressRoute circuit to the New York office to meet the business goals and technical requirements?

      • 500 Mbps
      • 1,000 Mbps
      • 2,000 Mbps
      • 5,000 Mbps
      Explanation:
      ExpressRoute circuits are configured to allow you to burst up to two times the bandwidth limit you procured for no additional cost.

      Scenario: It is estimated that during the migration, the bandwidth required between Azure and the New York office will be 1 Gbps. After the migration, a traffic burst of up to 3 Gbps will occur.

   2. You are planning the Azure network infrastructure to support the disaster recovery requirements.

      What is the minimum number of virtual networks required for the SAP deployment?

      • 1
      • 2
      • 3
      • 4
      Explanation:
      Scenario: Ensure that all the production databases can withstand the failure of an Azure region.

      Note: Use Azure Site Recovery to replicate applications across regions. Azure Site Recovery replicates workloads running on physical and virtual machines from a primary site (either on-premises or in Azure) to a secondary location (in Azure). When an outage occurs at the customer’s primary site, a failover can be triggered to quickly return the customer to an operational state. After the primary location is restored, customers can then fail back.

7. HOTSPOT

   You have an on-premises SAP environment.

   Backups are performed by using tape backups. There are 50 TB of backups.

   A Windows file server has BMP images of checks used by SAP Finance. There are 9 TB of images.

   You need to recommend a method to migrate the images and the tape backups to Azure. The solution must maintain continuous replication of the images.

   What should you include in the recommendation? To answer, select the appropriate options in the answer area.

   NOTE: Each correct selection is worth one point.

   

   

   Explanation:

   Tape backups: Azure DataBox
   The Microsoft Azure Data Box cloud solution lets you send terabytes of data into Azure in a quick, inexpensive, and reliable way. The secure data transfer is accelerated by shipping you a proprietary Data Box storage device. Each storage device has a maximum usable storage capacity of 80 TB and is transported to your datacenter through a regional carrier. The device has a rugged casing to protect and secure data during the transit.

   File server: Azure Storage Explorer
   Azure Storage Explorer is an application which helps you to easily access the Azure storage account through any device on any platform, be it Windows, MacOS, or Linux. You can easily connect to your subscription and manipulate your tables, blobs, queues, and files.

   Incorrect Answers:
   Not Azure Data Box Edge: Azure Data Box Edge is rebranded as Azure Stack Edge. Azure Stack Edge is a Hardware-as-a-service solution. Microsoft ships you a cloud-managed device with a built-in Field Programmable Gate Array (FPGA) that enables accelerated AI-inferencing and has all the capabilities of a network storage gateway.

8. You need direct connectivity from an on-premises network to SAP HANA (Large Instances). The solution must meet the following requirements:

   – Minimize administrative effort.
   – Provide the highest level of resiliency.

   What should you use?

   • ExpressRoute Global Reach
   • Linux IPTables
   • ExpressRoute
   • NGINX as a reverse proxy
   Explanation:

   The Azure network functionality used is:
   – Azure virtual networks are connected to the ExpressRoute circuit that connects to your on-premises network assets.
   – An ExpressRoute circuit that connects on-premises to Azure should have a minimum bandwidth of 1 Gbps or higher. This minimal bandwidth allows adequate bandwidth for the transfer of data between on-premises systems and systems that run on VMs. It also allows adequate bandwidth for connection to Azure systems from on-premises users.
   – All SAP systems in Azure are set up in virtual networks to communicate with each other.

9. You have an on-premises SAP environment hosted on VMware vSphere.

   You plan to migrate the environment to Azure by using Azure Site Recovery.

   You need to prepare the environment to support Azure Site Recovery.

   What should you deploy first?

   • an on-premises data gateway to vSphere
   • Microsoft System Center Virtual Machine Manager (VMM)
   • an Azure Backup server
   • a configuration server to vSphere
   Explanation:

   When you set up disaster recovery for on-premises VMware VMs, Site Recovery needs access to the vCenter Server/vSphere host so that the Site Recovery process server can automatically discover VMs, and fail them over as needed. By default the process server runs on the Site Recovery configuration server. Add an account for the configuration server to connect to the vCenter Server/vSphere host.

10. HOTSPOT

    You have an on-premises SAP environment. Application servers run on SUSE Linux Enterprise Server (SLES) servers. Databases run on SLES servers that have Oracle installed.

    You need to recommend a solution to migrate the environment to Azure. The solution must use currently deployed technologies whenever possible and support high availability.

    What should you include in the recommendation? To answer, select the appropriate options in the answer area.

    NOTE: Each correct selection is worth one point.

    

    

11. DRAG DROP

    You have an SAP environment on Azure.

    You use Azure Recovery Services to back up an SAP application server.

    You need to test the restoration process of a file on the server.

    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.

    

    

    Explanation:

    Step 1: From Azure Recover Vault, select File Recovery
    To restore files or folders from the recovery point, go to the virtual machine and choose the desired recovery point.

    Step 2: Download and run the mount disk executable

    Step 3: recover the file and unmount the disk

    

12. This question requires that you evaluate the underlined text to determine if it is correct.
