• Question 31:

  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: Back up directly to disk, copy the backups to an Azure virtual machine, and then copy the backup to an Azure Storage account.

  Does this meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead you should create a Recovery Services vault and a backup policy.

  What should you use?

  A. ethtool

  B. netsh

  C. iometer

  D. fio

  Correct Answer: A

  Check for activity on the VF (virtual function) with the ethtool -S eth0 | grep vf_ command. If you receive output similar to the following sample output, accelerated networking is enabled and working.

  vf_rx_packets: 992956 vf_rx_bytes: 2749784180 vf_tx_packets: 2656684 vf_tx_bytes: 1099443970 vf_tx_dropped: 0 Accelerated Networking is now enabled for your VM.

• Question 35:

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

  You have an SAP environment on Azure that uses Microsoft SQL Server as the RDBMS.

  You plan to migrate to an SAP HANA database.

  To calculate the amount of memory and disk space required for the database, you can use SAP Quick Sizer.

  Instructions: Review the underlined text. If it makes the statement correct, select “No change is needed”. If the statement is incorrect, select the answer choice that makes the statement correct.

  A. No change is needed

  B. Azure Migrate

  C. /SDF/HDB_SIZING

  D. SQL Server Management Studio (SSMS)

  Correct Answer: C

  If you want to move an existing deployed system from another relational database management system (RDBMS) to HANA. SAP provides reports to run on your existing SAP system. If the database is moved to HANA, these reports check

  the data and calculate memory requirements for the HANA instance.

  /SDF/HDB_SIZING is a standard Executable ABAP Report available within your SAP system (depending on your version and release level).

  Incorrect Answers:

  A: When you're starting an implementation from scratch, SAP Quick Sizer will calculate memory requirements of the implementation of SAP software on top of HANA.

• Question 36:

  You have an SAP landscape on Azure that contains the virtual machines shown in the following table.

  

  You need to ensure that the Application Server role is available if a single Azure datacenter fails.

  What should you include in the solution?

  A. a local network gateway

  B. Azure Load Balancer Standard

  C. Azure Virtual WAN

  D. Azure Active Directory (Azure AD) Application Proxy

  Correct Answer: B

  For the load balancers of the failover clusters of SAP Central Services and the DBMS layer, you need to use the Standard SKU Azure Load Balancer. The Basic Load Balancer won't work across zones.

  Note:

  The DBMS also is a single point of contact in an SAP system. You need to protect it by using a high-availability solution. The following figure shows a SQL Server AlwaysOn high-availability solution in Azure, with Windows Server Failover

  Clustering and the Azure internal load balancer.

  Incorrect Answers:

  C: Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface.

  D: Application Proxy is recommended for giving remote users access to internal resources. Application Proxy replaces the need for a VPN or reverse proxy for these remote access use cases.

• Question 37:

  You have an on-premises third-party enterprise resource planning (ERP) system that uses Microsoft SQL Server 2016.

  You plan to migrate the ERP system to SAP Business Suite on SAP HANA on Azure virtual machines.

  You need to identify the appropriate sizing for Business Suite on HANA.

  What should you use?

  A. SAP Quick Sizer for HANA Cloud

  B. HANA Cockpit

  C. SAP Quick Sizer for HANA

  D. SAP Cloud Platform Cockpit

  Correct Answer: A

  If a customer runs non-SAP systems, the only way of Sizing the required Hardware for SAP HANA is the Quick-Sizer tool.

  B. DB01

  C. DB12

  D. ST06

  Correct Answer: D

• Question 39:

  You have an on-premises SAP landscape that contains an IBM DB2 database.

  You need to recommend a solution to migrate the landscape to Azure and the database to SAP HANA. The solution must meet the following requirements:

  1.

  Be supported by SAP.

  2.

  Minimize downtime.

  What should you include in the recommendation?

  A. SAP Database Migration Option (DMO) with System Move

  C. Azure Import/Export service

  D. Azure Data Box Gateway

  Correct Answer: A

  In 2013, SAP introduced new procedure called Database Migration Option (part of Software Update Manager), which can help you during the migration to HANA database. It combines Unicode conversion, system update and database migration into a single step which extremely simplified the overall process.

  Reference: https://blogs.sap.com/2017/10/05/your-sap-on-azure-part-2-dmo-with-system-move/

• Question 40:

  You have an on-premises SAP landscape that contains a 20-TB IBM DB2 database. The database contains large tables that are optimized for read operations via secondary indexes.

  You plan to migrate the database platform to SQL Server on Azure virtual machines.

  You need to recommend a database migration approach that minimizes the time of the export stage.

  What should you recommend?

  A. log shipping

  B. deleting secondary indexes

  C. SAP Database Migration Option (DMO) in parallel transfer mode
