   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. HOTSPOT

      You are evaluating the proposed backup policy.

      For each of the following statements, select Yes if the statement is true. Otherwise, select No.

      NOTE: Each correct selection is worth one point.

      

      

      Explanation:

      Box 1: Yes
      Scenario: Technical requirements: Ensure that an application server can be restored from a backup created during the last five days within 15 minutes.

      Instant Restore has ‘The instance recovery snapshot(s) for 5 Day(s)’.

      Box 2: No
      Scenario: Ensure that all the production application servers can restore daily backups from the last 21 days.

      The Retention of daily backup point is set to for 14 days only.

      Box 3: Yes

   2. HOTSPOT

      You are planning replication of the SAP HANA database for the disaster recovery environment in Azure.

      For each of the following statements, select Yes if the statement is true. Otherwise, select No.

      NOTE: Each correct selection is worth one point.

      

      

      Explanation:

      Box 1: No
      SAP HANA Replication consists of one primary node and at least one secondary node. Changes to the data on the primary node are replicated to the secondary node synchronously or asynchronously.
      ‎
      Box 2: No
      Since SPS11 SAP HANA system replication can be run in two different operation
      modes:
      – delta_datashipping
      – logreplay

      Box 3: Yes

3. You are migrating SAP to Azure. The ASCS application servers are in one Azure zone, and the SAP database server in in a different Azure zone. ASCS/ERS is configured for high availability.

   During performance testing, you discover increased response times in Azure, even though the Azure environment has better computer and memory configurations than the on-premises environment.

   During the initial analysis, you discover an increased wait time for Enqueue.

   What are three possible causes of the increased wait time? Each correct answer presents a complete solution.

   NOTE: Each correct selection is worth one point.

   • a missing Enqueue profile
   • disk I/O during Enqueue backup operations
   • misconfigured load balancer rules and health check probes for Enqueue and ASCS
   • active Enqueue replication
   • network latency between the database server and the SAP application servers

   Explanation:

   E: The network latency across Availability Zones is not the same in all Azure regions. In some cases, you can deploy and run the SAP application layer across different zones because the network latency from one zone to the active DBMS VM is acceptable. But in some Azure regions, the latency between the active DBMS VM and the SAP application instance, when deployed in different zones, might not be acceptable for SAP business processes.

4. You have an on-premises SAP environment that uses AIX servers and IBM DB2 as the database platform.

   You plan to migrate SAP to Azure. In Azure, the SAP workloads will use Windows Server and Microsoft SQL Server as the database platform.

   What should you use to export from DB2 and import the data to SQL Server?

   • R3load
   • Azure SQL Data Warehouse
   • SQL Server Management Studio (SSMS)
   • R3trans
   Explanation:

   To migrate DB2 databases to SQL Server, you must connect to the DB2 database that you want to migrate. When you connect, SSMA obtains metadata about all DB2 schemas, and then displays it in the DB2 Metadata Explorer pane.

5. HOTSPOT

   You are designing the backup for an SAP database.

   You have an Azure Storage account that is configured as shown in the following exhibit.

   

   Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.

   NOTE: Each correct selection is worth one point.

   

   

   Explanation:

   Box 1: standard solid-state drives (SSDs)
   Standard SSD Managed Disks, a low-cost SSD offering, are optimized for test and entry-level production workloads requiring consistent latency.

   Box 2: to another Azure region
   Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region that is hundreds of miles away from the primary region.

6. DRAG DROP

   You migrate SAP ERP Central Component (SAP ECC) production and non-production landscapes to Azure.

   You are licensed for SAP Landscape Management (LaMa).

   You need to refresh from the production landscape to the non-production 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: From the Azure portal, create a service principal
   The Azure connector can use a Service Principal to authorize against Microsoft Azure. Follow these steps to create a Service Principal for SAP Landscape Management (LaMa).

   Step 2: Add permissions to the service principal
   The Service Principal does not have permissions to access your Azure resources by default. You need to give the Service Principal permissions to access them.

   Step 3: From the Cloud Managers tab in LaMa, add an adapter
   Create a new connector in SAP LaMa
   Open the SAP LaMa website and navigate to Infrastructure. Go to tab Cloud Managers and click on Add. Select the Microsoft Azure Cloud Adapter

   Step 4: Install and configure LaMA on an SAP NetWeater instance
   Provision a new adaptive SAP system
   You can manually deploy a new virtual machine or use one of the Azure templates in the quickstart repository. It contains templates for SAP NetWeaver ASCS, SAP NetWeaver application servers, and the database. You can also use these templates to provision new hosts as part of a system copy/clone etc.

   Note: To support customers on their journey into a cloud model (hybrid or entirely public cloud), SAP and Microsoft partnered to create an adapter that integrates the SAP management capabilities of LaMa with the IaaS advantages of Microsoft Azure.

7. HOTSPOT

   For each of the following statements, select Yes if the statement is true. Otherwise, select No.

   NOTE: Each correct selection is worth one point.

   

   

   Explanation:

   Box 1: Yes

   Box 2: Yes
   Oracle Database 12c Release 2 (12.2) is certified on Microsoft Windows Server 2016 (Standard, Datacenter, and Essentials Editions), which includes support for the database client, server, and Oracle Real Application Clusters.
   Organizations can run SAP applications with Oracle databases on the same code base on Unix, Linux, and Windows operating systems.

   Box 3: Yes
