You have an Azure subscription that contains two SAP HANA on Azure (Large Instances) deployments named HLI1 and HLI2. HLI1 is deployed to the East US Azure region. HLI2 is deployed to the West US 2 Azure region.

You need to minimize network latency for inter-region communication between HLI1 and HLI2.

What should you implement?

  1. a NAT gateway
  2. IP routing tables
  3. ExpressRoute FastPath
  4. ExpressRoute Global Reach

Answer(s): D

Explanation:

ExpressRoute Global Reach SAP HANA on Azure (Large Instances) for inter-region communication With ExpressRoute Global Reach, you can link ExpressRoute circuits together to make a private network between your on-premises networks.
Use case
ExpressRoute Global Reach is designed to complement your service provider's WAN implementation and connect your branch offices across the world. For example, if your service provider primarily operates in the United States and has linked all of your branches in the U.S., but the service provider doesn't operate in Japan and Hong Kong Special Administrative Region, with ExpressRoute Global Reach you can work with a local service provider and Microsoft to connect your branches there to the ones in the U.S. using ExpressRoute and
our global network.
Note: If SAP HANA on Azure (Large Instances) is deployed in multiple Azure regions, a separate tenant is deployed in the HANA Large Instance stamp. You can run both under the same Azure subscription provided these instances are part of the same SAP landscape.
Incorrect:
Not C: FastPath is designed to improve the data path performance between your on-premises network and your virtual network. When enabled, FastPath sends network traffic directly to virtual machines in the virtual network, bypassing the gateway.

NOTE: Each correct selection is worth one point.

Hot Area:

  1. See Explanation for the Answer.

Answer(s): A

Explanation:



Box 1: SAP Database Option (DMO) with System Move

Database Migration Option (DMO)
DMO of Software Update Manager (SUM) in a nutshell

SUM does not only offer to update software components, but can also execute a database migration (for ABAP based systems)
DMO is the combination of software update with the database migration To only migrate the database (without software update), the approach "DMO without system update" can be used
The standard DMO is an inplace-procedure, as it keeps the Application Server level unchanged, only changes the database (host)
To combine the database migration with a move of the system to a different environment, "DMO with system move" can be used
Specifically for the conversion to SAP S/4HANA, DMOVE2S4 can be used as alternative for "DMO with system move"
DMO allows an easy reset of the procedure at any point in time DMO allows migration to SAP HANA DB, and (depending on scenario) to other database types as well SUM 1.0 (for target systems based on SAP BASIS 7.40 and lower) allows to execute a Unicode conversion as part of the migration

Incorrect:
* Azure Database Migration Service
Azure Database Migration Service enables seamless migrations from multiple database sources to Azure Data platforms with minimal downtime. The service uses the Data Migration Assistant to generate assessment reports that provide recommendations to guide you through the changes required before performing a migration. When you're ready to begin the migration process, Azure Database Migration Service performs all the required steps.

* Data Migration Assistant (DMA)
The Data Migration Assistant (DMA) helps you upgrade to a modern data platform by detecting compatibility issues that can impact database functionality in your new version of SQL Server or Azure SQL Database.

Note: With Microsoft Azure, you can migrate your existing SAP application running on IBM Db2 for Linux, UNIX, and Windows (LUW) to Azure virtual machines. With SAP on IBM Db2 for LUW, administrators and developers

can still use the same development and administration tools, which are available on-premises.

Box 2: AzCopy
The size of the files, 50 GB, makes it suitable for AzCopy rather than for Databox.

Use AzCopy from a Windows or Linux command line to easily copy data to and from Blob Storage, Azure File Storage, and Azure Table Storage with optimal performance. AzCopy supports concurrency and parallelism, and the ability to resume copy operations when interrupted. You can also use AzCopy to copy data from AWS to Azure. For programmatic access, the Microsoft Azure Storage Data Movement Library is the core framework that powers AzCopy. It's provided as a .NET Core library.

Incorrect:
* Azure Migrate
The Azure Migrate: Discovery and assessment tool discovers and assesses on-premises VMware VMs, Hyper- V VMs, and physical servers for migration to Azure. Here's what the tool does: Azure readiness: Assesses whether on-premises servers, SQL Servers and web apps are ready for migration to Azure.

* Azure Data Box
The Microsoft Azure Data Box cloud solution lets you send terabytes of data into and out of 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.

You can order the Data Box device via the Azure portal to import or export data from Azure. Once the device is received, you can quickly set it up using the local web UI. Depending on whether you will import or export data, copy the data from your servers to the device or from the device to your servers, and ship the device back to Azure. If importing data to Azure, in the Azure datacenter, your data is automatically uploaded from the device to Azure. The entire process is tracked end-to-end by the Data Box service in the Azure portal.

Use cases
Data Box is ideally suited to transfer data sizes larger than 40 TBs in scenarios with no to limited network connectivity. The data movement can be one-time, periodic, or an initial bulk data transfer followed by periodic transfers.



You are planning a small-scale deployment of an SAP HANA on Azure (Large Instances) landscape.

You identify the costs of the virtual machine SKU required to host the HANA Large Instances landscape.

Which additional costs will be incurred?

  1. a Linux support contract
  2. an ExpressRoute circuit between the HANA Large Instances stamp and Azure
  3. a Site-to-Site VPN connection between the HANA Large Instances stamp and Azure
  4. an Azure Rapid Response support contract

Answer(s): B

Explanation:

SAP HANA (Large Instances) network architecture
Azure offers different services that allow you to run the DBMS, NetWeaver, and S/4HANA systems in Azure.
Azure offers network technology to make Azure look like a virtual data center to your on-premises software deployments. The Azure network functionality includes:
Azure virtual networks connected to the ExpressRoute circuit that connects to your on-premises network assets.
An ExpressRoute circuit that connects on-premises to Azure with a minimum bandwidth of 1 Gbps or higher.
This circuit allows adequate bandwidth for the transfer of data between on-premises systems and systems that run on virtual machines (VMs). It also allows adequate bandwidth for connection to Azure systems from on- premises users.
All SAP systems in Azure set up in virtual networks to communicate with each other.
Active Directory and DNS hosted on-premises are extended into Azure through ExpressRoute from on- premises. They may also run completely in Azure.



Your on-premises network has a 100-Mbps internet connection and contains an SAP production landscape that has 14 TB of data files.

You plan to migrate the on-premises SAP landscape to Azure.

You need to migrate the data files to an Azure Files share. The solution must meet the following requirements:

Migrate the files within seven days.


Minimize administrative effort.


Minimize service outages.


What should you use?

  1. Azure Migrate
  2. AzCopy
  3. Azure Data Box
  4. Azure Site Recovery

You are planning a deployment of SAP on Azure that will use SAP HANA.

You need to ensure that the SAP application servers are in the same datacenter as the HANA nodes.

What should you use?

  1. an application group
  2. a proximity placement group
  3. a resource group
  4. a virtual machine scale set

Answer(s): B

Explanation:

Proximity Placement Groups
Proximity placement groups enable the grouping of different VM types under a single network spine, ensuring optimal low network latency between them. When the first VM is deployed in proximity placement group, that VM gets bound to a specific network spine. As all the other VMs that are going to be deployed into the same proximity placement group, those VMs get grouped under the same network spine.



HOTSPOT (Drag and Drop is not supported)

You have an Azure subscription.

You need to deploy multiple virtual machines that will host SAP HANA by using an Azure Resource Manager (ARM) template. The solution must meet SAP certification requirements.

How should you complete the template? To answer, select the appropriate options in the answer area.

  1. See Explanation for the Answer.

Answer(s): A

Explanation:




Box 1: EnableAcceleratedNetworking
Maximize your VM's Performance with Accelerated Networking now generally available for both Windows and Linux.

Note: We are happy to announce that Accelerated Networking (AN) is generally available (GA) and widely available for Windows and the latest distributions of Linux providing up to 30Gbps in networking throughput, free of charge!

AN provides consistent ultra-low network latency via Azure's in-house programmable hardware and technologies such as SR-IOV. By moving much of Azure's software-defined networking stack off the CPUs and into FPGA-based SmartNICs, compute cycles are reclaimed by end user applications, putting less load on the VM, decreasing jitter and inconsistency in latency.

With the GA of AN, region limitations have been removed, making the feature widely available around the

world. Supported VM series include D/DSv2, D/DSv3, E/ESv3, F/FS, FSv2, and Ms/Mms.

Box 2: Standard_M64s
Comparing what is certified (in general) with what is certified for HANA, we can see the following (as at Apr 2020):

VM Type VMSize Mem 2-Tier SAPS
Standard_M32ts 32vCPU 192 33,670
Standard_M32ls 32vCPU 256 33,670
