NEW QUESTION # 50
You plan to deploy an SAP environment on Azure that will use Azure Availability Zones.
Which load balancing solution supports the deployment?
Answer: A
Explanation:
When you deploy Azure VMs across Availability Zones and establish failover solutions within the same Azure region, some restrictions apply:
You can't use an Azure Basic Load Balancer to create failover cluster solutions based on Windows Server Failover Clustering or Linux Pacemaker. Instead, you need to use the Azure Standard Load Balancer SKU.

Box 1: A proximity placement group
Azure 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 thebest 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 Networking
To 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.
Box 3: Network Performance Monitor
Network 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 Monitor
ExpressRoute Monitor
Note 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.

NEW QUESTION # 54
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:
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.
