A.

Increase the tempdb size on the SQL Server virtual machines.


B.

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


A.

Yes


B.

No





B.
  

No



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

You have an SAP production landscape that uses SAP HANA databases on Azure. The HANA database server is a Standard.M32ms Azure virtual machine that has 864 GB of RAM. The HANA database is 400 GB. You expect the database to grow by 40 percent during the next 12 months. You resize the HANA database server virtual machine to Standard_m64ms and ,024 GB of RAM. You need to recommend additional changes to minimize performance degradation caused by database growth What should you recommend for the HANA database server?


A.

Increase the number of vCPUs.


B.

Configure additional disks


C.

Add a secondary network interface.


D.

Add a scale out node.





A.
  

Increase the number of vCPUs.



You have an SAP environment on Azure. your on-promises network connects to Azure by using a site-to-site VPN connection.

6u need to alert technical support if the network bandwidth usage between the on-premises network and Azure exceeds 900 Mbps 10 minutes. What should you use?


A.

Azure Network Watcher


B.

NIPING


C.

Azure Monitor


D.

Azure Enhanced Monitoring for SAP





C.
  

Azure Monitor



Explanation:
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.

You are deploying an SAP environment on Azure that will use an SAP HANA database server. You provision an Azure virtual machine for SAP HANA by using the M64s virtual machine SKU.  You need to set the swap space by using the Microsoft Azure Linux Agent (waagent) configuration file. Which two settings should you configure? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.


A.

ResourceDisk.EnableSwapEncryption=n


B.

AutoUpdate.Enabled=n


C.

ResourceDisk.SwapSizeMB=229376


D.

ResourceDisk.EnableSwap=y





C.
  

ResourceDisk.SwapSizeMB=229376



D.
  

ResourceDisk.EnableSwap=y



Explanation:

To create a swap file in the directory that's defined by the ResourceDisk.MountPoint parameter, you can update the /etc/waagent.conf file by setting the following three parameters:
ResourceDisk.Format=y ResourceDisk.EnableSwap=y ResourceDisk.SwapSizeMB=xx

You have an Azure subscription.You plan to deploy a SAP NetWeaver landscape that will use SQL Server on Azure virtual machines. The solution must meet the following requirements:

The SAP application and database tiers must reside in the same Azure zone. The application tier in the Azure virtual machines must belong to the same Availability Set.

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.

NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.






Answer:

Explanation:

Step 1: Create a proximity placement group
A proximity placement group is a logical grouping of Azure resources within the same Azure data center in order to reduce latency.

Step 2: Create an Availability Set
Create an availability set that references the Azure proximity group.
By adding the availability sets to proximity placement groups, the network latencies are considerably reduced, thereby improving the overall performance.

Step 3: Deploy SQL Server on Azure Virtual machines

Step 4: Deploy the application tier in the Azure virtual machines
Deploy the application layer VMs by referencing the availability set and the proximity placement group.
