Microsoft Microsoft Certifications AZ-120 Questions & Answers

• Question 61:

  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 the makes the stamen 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).

• Question 62:

  You plan to deploy a high availability SAP environment that will use a failover clustering solution.

  You have an Azure Resource Manager template that you will use for the deployment. You have the following relevant portion of the template.

  

  What is created by the template?

  A. a zone-redundant public IP address for the internal load balancer

  B. a zone-redundant frontend IP address for the internal Azure Basic Load Balancer

  C. a zone-redundant frontend IP address for the internal Azure Standard Load Balancer

  D. a zonal frontend IP address for the internal Azure Standard Load Balancer

  Correct Answer: D

  A Load Balancer can either be zone redundant, zonal, or non-zonal.

  Goto azure portal and create a load balancer it would give you 5 options possibly for Availability Zone : No Zone , Zone Redundant , 1 , 2, 3.

• Question 63:

  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?

  A. robocopy

  B. backint

  C. azcopy

  D. scp

  Correct Answer: C

  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.

  Reference: https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/sap-hana-backup-file-level

• Question 64:

  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?

  A. an on-premises data gateway to vSphere

  B. Microsoft System Center Virtual Machine Manager (VMM)

  C. an Azure Backup server

  D. a configuration server to vSphere

  Correct Answer: D

  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.

  Reference: https://docs.microsoft.com/en-us/azure/site-recovery/vmware-azure-manage-vcenter

• Question 65:

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

  When deploying SAP HANA to an Azure virtual machine, you can enable Write Accelerator to reduce the latency between the SAP application servers and the database layer.

  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. install the Mellanox driver

  C. start the NIPING service

  D. enable Accelerated Networking

  Correct Answer: D

  To further reduce network latency between Azure VMs, we [Microsoft] recommend that you choose Azure Accelerated Networking. Use it when you deploy Azure VMs for an SAP workload, especially for the SAP application layer and the SAP DBMS layer.

  Incorrect Answers:

  A: Write Accelerator is a disk capability for M-Series Virtual Machines (VMs) on Premium Storage with Azure Managed Disks exclusively. As the name states, the purpose of the functionality is to improve the I/O latency of writes against Azure Premium Storage.

  B: Mellanox offers a robust and full set of protocol software and driver for Linux with the ConnectX EN family cards. Designed to provide a high performance support for Enhanced Ethernet with fabric consolidation over TCP/IP based LAN applications. The driver and software in conjunction with the Industry's leading ConnectX family of cards achieve full line rate, full duplex of up to 100Gbps performance per port.

  C: To analyze network issue or measure network metrics you can test the connection using SAP's NIPING program. You can use NIPING to analyze the network connection between any two machines running SAP software.

• Question 66:

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

  1.

  Minimize administrative effort.

  2.

  Provide the highest level of resiliency. What should you use?

  A. ExpressRoute Global Reach

  B. Linux IPTables

  C. ExpressRoute

  D. NGINX as a reverse proxy

  Correct Answer: A

  https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/hana-network-architecture

  Express Route Global Reach Microsoft introduced a new functionality called ExpressRoute Global Reach. Global Reach can be used for HANA Large Instances in two scenarios:

  Enable direct access from on-premises to your HANA Large Instance units deployed in different regions Enable direct communication between your HANA Large Instance units deployed in different regions Direct Access from on-premises In

  the Azure regions where Global Reach is offered, you can request enabling the Global Reach functionality for your ExpressRoute circuit that connects your on-premises network to the Azure virtual network that connects to your HANA Large

  Instance units as well.

• Question 67:

  You are deploying SAP Fiori to an SAP environment on Azure.

  You are configuring SAML 2.0 for an SAP Fiori instance named FPP that uses client 100 to authenticate to an Azure Active Directory (Azure AD) tenant.

  Which provider named should you use to ensure that the Azure AD tenant recognizes the SAP Fiori instance?

  A. https://FPP

  B. ldap://FPP

  C. https://FPP100

  D. ldap://FPP-100

  Correct Answer: C

  By default, the provider name is in the format . Azure AD expects the name in the format ://. We recommend that you maintain the provider name as https:// so you can configure multiple SAP Fiori ABAP engines in Azure AD.

  Example:

• Question 68:

  You have an SAP environment on Azure.

  Your on-premises network connects to Azure by using a site-to-site VPN connection.

  What should you use?

  A. NIPING

  B. Azure Enhanced Monitoring for SAP

  C. Azure Network Watcher

  D. Azure Monitor

  Correct Answer: D

  You set up alerts on Azure VPN Gateway metrics. Azure Monitor provides the ability to set up alerts for Azure resources. You can set up alerts for virtual network gateways of the "VPN" type.

  Metric: AverageBandwidth: Average combined bandwidth utilization of all site-to-site connections on the gateway.
