HOTSPOT (Drag and Drop is not supported)You are planning the deployment of a three-tier SAP landscape on Azure that will use SAP HANA. The solution must meet the following requirements:Network latency between SAP NetWeaver and HANA must be minimized.An SAP production landscape on Azure must be supported.Network performance must be validated regularly.What should you include in the solution? To answer, select the appropriate options in the answer area.NOTE: Each correct selection is worth one point.Hot Area:
Answer(s): A
Box 1: A proximity placement groupAzure offers proximity placement groups. Proximity placement groups can be used to force grouping of different VM types into a single Azure datacenter to optimize the network latency between these different VM types to the best possible. In the process of deploying the first VM into such a proximity placement group, the VM gets bound to a specific datacenter.Note: SAP applications based on the SAP NetWeaver or SAP S/4HANA architecture are sensitive to network latency between the SAP application tier and the SAP database tier. This sensitivity is the result of most of the business logic running in the application layer. Because the SAP application layer runs the business logic, it issues queries to the database tier at a high frequency, at a rate of thousands or tens of thousands per second. In most cases, the nature of these queries is simple. They can often be run on the database tier in 500 microseconds or less.Box 2: Enable Accelerated NetworkingTo further reduce network latency between Azure VMs, we 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:Azure Write Accelerator is a functionality that is available for Azure M-Series VMs exclusively. As the name states, the purpose of the functionality is to improve I/O latency of writes against the Azure premium storage. For SAP HANA, Write Accelerator is supposed to be used against the /hana/log volume only. Therefore, the /hana/data and /hana/log are separate volumes with Azure Write Accelerator supporting the / hana/log volume only.Box 3: Network Performance MonitorNetwork Performance Monitor (NPM) - a cloud-based network monitoring solution for cloud-only, on-premises, and hybrid networking environments.Network Performance Monitor offers three broad capabilities:Performance Monitor: You can monitor network connectivity across cloud deployments and on-premises locations, multiple data centers, and branch offices and mission-critical multitier applications or microservices. With Performance Monitor, you can detect network issues before users complain.Service Connectivity MonitorExpressRoute MonitorNote 2: Azure Monitor for SAP Solutions is an Azure-native monitoring product for anyone running their SAP landscapes on Azure. It works with both SAP on Azure Virtual Machines and SAP on Azure Large Instances.Incorrect Answers:Apache JMeter is a free and open source tool for performance testing of web applications.SAP application server to database server latency can be tested with ABAPMeter report /SSA/CAT. Latency between SAP application server and DBMS server can be tested using TCPPing (Ping is not an accurate tool on Azure) or the SAP ABAP report /SSA/CAT -> ABAPMeter columns DB Access and E. DB Access.
HOTSPOT (Drag and Drop is not supported)For each of the following statements, select Yes if the statement is true. Otherwise, select No.NOTE: Each correct selection is worth one point.Hot Area:
Box 1: YesThe following is a quick checklist of storage configuration best practices for running your SQL Server on AzureVM:Place data, log, and tempdb files on separate drives.Box 2: YesAccelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the data path, which reduces latency, jitter, and CPU utilization for the most demanding network workloads on supported VM types.Box 3: NoNote: The maximum transmission unit (MTU) is the largest size frame (packet), specified in bytes, that can be sent over a network interface. The MTU is a configurable setting. The default MTU used on Azure VMs, and the default setting on most network devices globally, is 1,500 bytes.
HOTSPOT (Drag and Drop is not supported)You have an SAP production landscape that uses SAP HANA databases.You configure a metric alert for the primary HANA server as shown in the following exhibit.You have an action group shown in the following exhibit.The amy_email is configured as shown in the following exhibit.For each of the following statements, select Yes if the statement is true. Otherwise, select No.NOTE: Each correct selection is worth one point.Hot Area:
Box 1: NoThe period is 15 minutes. Only alerts or emails will be sent.Box 2: YesBox 3: Yes
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: 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?
Answer(s): B
Instead you should create a Recovery Services vault and a backup policy.

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?
For this question these are the correct answers:* Azure Application Gateway v2Application Gateway is available under a Standard_v2 SKU. Web Application Firewall (WAF) is available under a WAF_v2 SKU. The v2 SKU offers performance enhancements and adds support for critical new features like autoscaling, zone redundancy, and support for static VIPs.Zone redundancy: An Application Gateway or WAF deployment can span multiple Availability Zones, removing the need to provision separate Application Gateway instances in each zone with a Traffic Manager. You can choose a single zone or multiple zones where Application Gateway instances are deployed, which makes it more resilient to zone failure. The backend pool for applications can be similarly distributed across availability zones.Zone redundancy is available only where Azure Zones are available.* Azure Load Balancer StandardFor 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.For this question these are the incorrect answers:* a local network gateway* Azure Active Directory (Azure AD) Application Proxy* Azure AD Application ProxyApplication 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.* Azure Application Gateway v1* Azure Basic Load BalancerThe Basic Load Balancer won't work across zones.* Azure Private Link* Azure Virtual WANAzure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface.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 WindowsServer Failover Clustering and the Azure internal load balancer.
